AB  - We have recently characterized experimental autoimmune encephalomyelitis (EAE) induced in DA rats with spinal cord homogenate without complete Freund’s adjuvant (CFA). The main advantage of this multiple sclerosis model is the lack of CFA-related confounding effects which represent the major obstacles in translating findings from EAE to multiple sclerosis. Here, antigen specificity of the cellular and humoral immune response directed against the central nervous system was explored. The reactivity of T and B cells to myelin basic protein, myelin oligodendrocyte glycoprotein, and β-synuclein was detected. Having in mind that reactivity against β-synuclein was previously associated with autoimmunity against the brain, the infiltration of immune cells into different brain compartments, i.e. pons, cerebellum, hippocampus, and cortex was determined. T cell infiltration was observed in all structures examined. This finding stimulated investigation of the effects of immunization on DA rat behavior using the elevated plus maze and the open field test. Rats recovered from EAE displayed increased anxiety-like behavior. These data support CFA-free EAE in DA rats as a useful model for multiple sclerosis research.

AB  - Experimental autoimmune encephalomyelitis (EAE) induced in inbred rodents, i.e., genetically identical animals kept under identical environmental conditions, shows variable clinical outcomes. We investigated such variations of EAE in Dark Agouti rats immunized with spinal cord homogenate and identified four groups: lethal, severe, moderate, and mild, at day 28 post immunization. Higher numbers of CD4+ T cells, helper T cells type 1 (Th1) and 17 (Th17) in particular, were detected in the spinal cord of the severe group in comparison with the moderate group. In addition, increased proportion of Th1 and Th17 cells, and heightened levels of interferon (IFN)-γ and interleukin (IL)-6 were detected in the small intestine lamina propria of the severe group. A selective agonist of free fatty acid receptor type 2 (Ffar2) applied orally in the inductive phase of EAE shifted the distribution of the disease outcomes towards milder forms. This effect was paralleled with potentiation of intestinal innate lymphoid cells type 3 (ILC3) regulatory properties, and diminished Th1 and Th17 cell response in the lymph nodes draining the site of immunization. Our results suggest that different clinical outcomes in DA rats are under determinative influence of intestinal ILC3 activity during the inductive phase of EAE.

AB  - Experimental autoimmune encephalomyelitis (EAE) in inbred rodents commonly shows different clinical courses, so that the diseased animals can be clustered into four groups: mild. moderate, severe and lethal. Our aim was to determine biomolecular markers in the preclinical phase of EAE that allow the prediction of clinical course. 
Methods: Female Dark Agouti rats were immunized with spinal cord homogenate without adjuvant and examined for four weeks for clinical signs of EAE. Cells and sera from blood collected on days 0, 3, and 7 after immunization were processed for detection of proinflammatory cytokines (IL-1, IL-6, TNF, and IFN) by "real-time" RT-PCR and ELISA, respectively. 
Results: Induction of EAE resulted in the downregulation of IFN and TNF in the preclinical phase of disease, whereas IL-1 and IL-6 expression levels were unaffected. However, there was no correlation between the relative expression of IFN or TNF and the cumulative clinical score (sum of daily clinical scores), suggesting that they are not predictive markers of EAE severity. Our preliminary results that suggest a negative correlation between IL-1 expression level before EAE induction and cumulative score require further justification. 
Conclusion: The proinflammatory cytokines investigated so far in our study cannot be considered as good biomarkers of EAE severity. However, the downregulation of IFN and TNF in the blood cells during the asymptomatic phase of EAE suggests that they enter the central nervous system early from the bloodstream, which argues for the study of chemokine and/or chemokine receptors expression as potential biomarkers for the clinical courses of EAE.

AB  - Experimental autoimmune encephalomyelitis (EAE) is commonly induced with
central nervous system antigens mixed with complete Freund’s adjuvant (CFA). This
adjuvant has a confounding influence on the translational capacity of EAE as multiple
sclerosis (MS) model. Thus, we developed a novel subtype of EAE induced in Dark
Agouti (DA) rats with spinal cord homogenate (SCH) without CFA and characterized
it as a reliable MS model. Despite genetic homogeneity of experimental animals and
controlled environmental conditions, we observed variations in EAE clinical course in
SCH-immunized DA rats and four clinical groups were identified: lethal, severe,
moderate, and mild. Immune cells of spinal cord, small intestine lamina propria and
lymph nodes draining the site of immunization were compared between moderate and
severe group. Higher numbers of CD4+ T cells, regulatory T cells (Treg), helper T
cells type 1 (Th1) and 17 (Th17), and B cells were detected in the spinal cords of
severe group. Also, higher levels of interferon (IFN)-γ and interleukin (IL)-6 and an
increased proportion of Th1 and Th17 cells were detected in the lamina propria of the
severe group. Aminoguanidine – an inducible nitric oxide synthase inhibitor that was
applied to the rats during the effector phase of the disease ameliorated EAE and
imposed a shift of clinical outcomes towards milder variants. Our results suggest that
different clinical outcomes in DA rats come as a consequence of variability in the
strength of the effector mechanisms exerted within the CNS. The study of the
underlying mechanisms for the observed variability is necessary.

AB  - Aril ugljovodonični receptor (AhR) je transkripcioni faktor aktiviran ligandom i prevashodno je eksprimiran u imunskom tkivu creva. Kako istraživanja ukazuju na povezanost mukoznog imuniteta i različitih inflamatornih i autoimunskih oboljenja, ispitivali smo modulaciju imunskih ćelija creva pomoću novosintetisanog liganda AhR (šifra C43). Primenjen u kulturi mišjih CD4+ ćelija izolovanih iz mezenteričnih limfnih čvorova (MLČ), kao i na humanim ćelijama izolovanih iz tonzila, C43 je značajno uvećao udeo Treg nakon 24h. Nakon što je pokazano da C43 ne ostvaruje toksičnost (ni pri najvećim koncentracijama) pri razviću embriona zebrica (lat. Danio rerio), gavažom je 5 dana davan zdravim C57BL/6 mužjacima. U odnosu zastupljenosti Th1/Treg u MLČ, uočeno je pomeranje balansa ka Treg, kao i povećanje udela Treg koje eksprimiraju Cyp1a1 (nishodni signalni molekul od AhR) kod tretiranih miševa. Kada je C43 gavažom davan C57BL/6 mužjacima kojima je dijabetes tipa 1 (DT1) indukovan streptozotocinom, glikemijski indeksi su bili niži, a histološka analiza pankreasa je pokazala bolje očuvanje β ćelija i pankreasnih ostrvaca. Analiza lamine proprije tankog creva je pokazala povećanje udela tolerogenih dendritskih ćelija (tolDC), dok je udeo CD11b+MHCII+ ćelija bio snižen. Udeo Treg je takođe bio veći, kao i Cyp1a1+ Treg i IL-10+ Treg. Analizom pankreasnog limfnog čvora uočeno je sniženje udela Th1 i CD8+ ćelija, uz povećanje udela tolDC koje eksprimiraju indolamin 2,3-dioksigenazu, što je zabeleženo i u inflitratima pankreasa. Na osnovu dobijenih rezultata može se zaključiti da C43 ostvaruje antiinflamatorni efekat u DT1 i da pristup stimulacije AhR u mukozi creva može imati povoljan efekat u modulaciji autoimunosti i/ili inflamatornih oboljenja.

AB  - Gallic acid is a phenolic acid present in various plants, nuts, and fruits. It is well known for
its anti-oxidative and anti-inflammatory properties. The phenethyl ester of gallic acid (PEGA) was
synthesized with the aim of increasing the bioavailability of gallic acid, and thus its pharmacological
potential. Here, the effects of PEGA on encephalitogenic cells were examined, and PEGA was
found to modulate the inflammatory activities of T cells and macrophages/microglia. Specifically,
PEGA reduced the release of interleukin (IL)-17 and interferon (IFN)-γ from T cells, as well as NO,
and IL-6 from macrophages/microglia. Importantly, PEGA ameliorated experimental autoimmune
encephalomyelitis, an animal model of chronic inflammatory disease of the central nervous system
(CNS)—multiple sclerosis. Thus, PEGA is a potent anti-inflammatory compound with a perspective
to be further explored in the context of CNS autoimmunity and other chronic inflammatory disorders.

AB  - This study aimed to evaluate the effects of a synthetic gallic acid (GA) derivative in the
central nervous system (CNS) autoimmunity, i.e. in experimental autoimmune
encephalomyelitis (EAE), an animal model of multiple sclerosis. EAE was induced in DA
rats by injection of autologous spinal cord homogenate, with a gallic acid derivative being
applied subcutaneously (20 mg/kg, day 7-22 post-immunization). GA derivative
ameliorated EAE. Cells from lymph nodes draining the site of immunization (DLNC),
isolated in the inductive phase of the disease, and spinal cord immune cells (SCIC),
isolated at the peak of disease, were exposed to GA derivative in vitro. Encephalitogenic
cytokines, interferon (IFN)-γ and interleukin (IL)-17, were decreased in SCIC and DLNC
under the influence of GA derivative. The proportion of IL-17-producing CD4+ T cells was
reduced in SCIC (flow cytometry). Treatment of microglial BV2 cells with GA derivative
led to inhibition of NO, IL-6, and tumor necrosis factor release. These results imply that
the synthesized GA derivative is a potent immunomodulator, able to ameliorate EAE. Its
effects on the CNS autoimmunity are related to the inhibition of encephalitogenic T cells
and macrophage/microglia activity in our study.

AB  - Rosmarinic acid is a polyphenolic compound, abundantly present in herbs of the Lamiaceae family. The aim of
the study was to evaluate the immunomodulatory properties of a recently developed phenethyl ester derivative
of rosmarinic acid (PERA), with enhanced ability of diffusion through biological membranes, in an animal model
of the central nervous system (CNS) autoimmunity. To this end, experimental autoimmune encephalomyelitis
(EAE), an animal model of multiple sclerosis was used. Daily subcutaneous administration of PERA (30 mg/kg)
from day 7 to day 22 after immunization successfully ameliorated EAE induced in Dark Agouti rats, shortening
the disease duration and reducing maximal, cumulative and mean clinical score. PERA efficiently reduced
production of major encephalitogenic cytokines, interferon (IFN)-γ and interleukin (IL)-17, in immune cells from
the CNS or the lymph nodes draining the site of immunization of EAE rats, as well as in CD4+ T cells purified
from the lymph nodes. Also, PERA inhibited NO production in the CNS and the lymph nodes, as well as in
macrophages and microglial cells. Finally, microglial ability to produce pro-inflammatory cytokines IL-6, and
tumor necrosis factor (TNF) were also reduced by PERA. Our results clearly imply that PERA possesses antiencephalitogenic properties. Thus, further studies on the relevance of the observed effects for the therapy of
multiple sclerosis are warranted.

AB  - Experimental autoimmune encephalomyelitis (EAE) is classically induced with complete Freund's adjuvant (CFA). The immune response against CFA has a confounding influence on the translational capacity of EAE as a multiple sclerosis model. Here, we compare clinical, cellular and molecular properties between syngeneic spinal cord homogenate (SCH)- and SCH + CFA-immunized Dark Agouti rats. EAE signs were observed earlier and the cumulative clinical score was higher without CFA. Also, a higher number of immune cells infiltrates in the spinal cords was noticed at the peak of EAE without CFA. High spinal cord abundance of CD8+CD11bc+MHC class II+ cells was detected in SCH-immunized rats. Myelin basic protein -specific response can be elicited in the cells from the lymph nodes draining the site of SCH immunization. This CFA-free EAE is a reliable multiple sclerosis model.

AB  - Experimental autoimmune encephalomyelitis (EAE) is classically induced with complete Freund's adjuvant (CFA). The immune response against CFA has a confounding influence on the translational capacity of EAE as a multiple sclerosis model. Here, we compare clinical, cellular and molecular properties between syngeneic spinal cord homogenate (SCH)- and SCH + CFA-immunized Dark Agouti rats. EAE signs were observed earlier and the cumulative clinical score was higher without CFA. Also, a higher number of immune cells infiltrates in the spinal cords was noticed at the peak of EAE without CFA. High spinal cord abundance of CD8+CD11bc+MHC class II+ cells was detected in SCH-immunized rats. Myelin basic protein -specific response can be elicited in the cells from the lymph nodes draining the site of SCH immunization. This CFA-free EAE is a reliable multiple sclerosis model.

AB  - The development of collagen type II (CII)-induced arthritis (CIA), a model of rheumatoid arthritis, in rats housed in cages with bedding composed of Celliant fibres containing ceramic particles, which absorb body heat and re-emit the energy back to the body in the form of infrared radiation (+IRF rats), and those housed in cages with standard wooden shaving bedding (−IRF control rats) was examined. The appearance of the first signs of CIA was postponed, while the disease was milder (judging by the arthritic score, paw volume, and burrowing behaviour) in +IRF compared with −IRF rats. This correlated with a lower magnitude of serum anti-CII IgG antibody levels in +IRF rats, and lower production level of IL-17, the Th17 signature cytokine, in cultures of their paws. This could be partly ascribed to impaired migration of antigen-loaded CD11b + dendritic cells and their positioning within lymph nodes in +IRF rats reflecting diminished lymph node expression of CCL19 /CCL21. Additionally, as confirmed in rats with carrageenan-induced paw inflammation (CIPI), the infrared radiation from Celliant fibres, independently from immunomodulatory effects, exerted anti-inflammatory effects (judging by a shift in pro-inflammatory mediator to anti-inflammatory/immunoregulatory mediator ratio towards the latter in paw cultures) and ameliorated burrowing behaviour in CIA rats.

AB  - The incidence of multiple sclerosis (MS) and susceptibility of animals to experimental autoimmune encephalomyelitis (EAE), the most commonly used experimental model of MS, decrease with aging. Generally, autoimmune diseases develop as the ultimate outcome of an imbalance between damaging immune responses against self and regulatory immune responses (keeping the former under control). Thus, in this review the age-related changes possibly underlying this balance were discussed. Specifically, considering the central role of T cells in MS/EAE, the impact of aging on overall functional capacity (reflecting both overall count and individual functional cell properties) of self-reactive conventional T cells (Tcons) and FoxP3+ regulatory T cells (Tregs), as the most potent immunoregulatory/suppressive cells, was analyzed, as well. The analysis encompasses three distinct compartments: thymus (the primary lymphoid organ responsible for the elimination of self-reactive T cells – negative selection and the generation of Tregs, compensating for imperfections of the negative selection), peripheral blood/lymphoid tissues (“afferent” compartment), and brain/spinal cord tissues (“target” compartment). Given that the incidence of MS and susceptibility of animals to EAE are greater in women/females than in age-matched men/males, sex as independent variable was also considered. In conclusion, with aging, sex-specific alterations in the balance of self-reactive Tcons/Tregs are likely to occur not only in the thymus/”afferent” compartment, but also in the “target” compartment, reflecting multifaceted changes in both T-cell types. Their in depth understanding is important not only for envisaging effects of aging, but also for designing interventions to slow-down aging without any adverse effect on incidence of autoimmune diseases.

AB  - Gut immune cells have been increasingly appreciated as important players in the central nervous system (CNS) autoimmunity in animal models of multiple sclerosis (MS). Among the gut immune cells, innate lymphoid cell type 3 (ILC3) is of special interest in MS research, as they represent the innate cell counterpart of the major pathogenic cell population in MS, i.e. T helper (Th)17 cells. Importantly, these cells have been shown to stimulate regulatory T cells (Treg) and to counteract pathogenic Th17 cells in animal models of autoimmune diseases. Besides, they are also well known for their ability to stabilize the intestinal barrier and to shape the immune response to the gut microbiota. Thus, proper maintenance of the intestinal barrier and the establishment of the regulatory milieu in the gut performed by ILC3 may prevent activation of CNS antigen-specific Th17 cells by the molecular mimicry. Recent findings on the role of ILC3 in the gut-CNS axis and their relevance for MS pathogenesis will be discussed in this paper. Possibilities of ILC3 functional modulation for the benefit of MS patients will be addressed, as well.

AB  - Monocytes' plasticity has an important role in the development of rheumatoid arthritis (RA), an autoimmune disease exhibiting greater prevalence in women. Contribution of this phenomenon to sex bias in RA severity was investigated in rat collagen-induced arthritis (CIA) model of RA. The greater severity of CIA in females (exhibiting signs of bone resorption) was accompanied by the higher blood level of advanced oxidation protein products and a more pro-oxidant profile. Consistently, in females, the greater density of giant multinuclear cells (monocytes/macrophages and osteoclasts) in inflamed joint tissue was found. This correlated with the higher frequencies of CCR2- and CX3CR1- expressing cells (precursors of inflammatory monocytes/macrophages and osteoclasts) among CD11b+ splenocytes. This in conjunction with the enhanced migratory capacity of CD11b+ monocytic cells in females compared with males could be linked with the higher frequencies of CCR2+CX3CR1-CD43lowCD11b+ and CCR2-CX3CR1+CD43hiCD11b+ cells (corresponding to "classical" and "non-classical" monocytes, respectively) and the greater density of CD68+ cells (monocytes/macrophages and osteoclast precursors/osteoclasts) in blood and inflamed paws from female rats, respectively. Consistently, the higher levels of GM-CSF, TNF-α and IL-6, IL-1β (driving Th17 cell differentiation), and IL-17 followed by the lower level of IL-10 were measured in inflamed paw cultures from female compared with male rats. To the greater IL-17 production (associated with enhanced monocyte immigration and differentiation into osteoclasts) most likely contributed augmented Th17 cell generation in the lymph nodes draining arthritic joints from female compared with male rats. Overall, the study suggests the sex-specific contribution of monocytic lineage cells to CIA, and possibly RA development.

AB  - The study examined germinal centre (GC) reaction in lymph nodes draining inflamed joints and adjacent tissues (dLNs) in male and female Dark Agouti rat collagen type II (CII)-induced arthritis (CIA) model of rheumatoid arthritis. Female rats exhibiting the greater susceptibility to CIA mounted stronger serum CII-specific IgG response than their male counterparts. This correlated with the higher frequency of GC B cells in female compared with male dLNs. Consistently, the frequency of activated/proliferating Ki-67+ cells among dLN B cells was higher in females than in males. This correlated with the shift in dLN T follicular regulatory (Tfr)/T follicular helper (Tfh) cell ratio towards Tfh cells in females, and greater densities of CD40L and CD40 on their dLN T and B cells, respectively. The higher Tfh cell frequency in females was consistent with the greater dLN expression of mRNA for IL-21/27, the key cytokines involved in Tfh cell generation and their help to B cells. Additionally, in CII-stimulated female rat dLN cell cultures IFN-γ/IL-4 production ratio was shifted towards IFN-γ. Consistently, the serum IgG2a(b)/IgG1 CII-specific antibody ratio was shifted towards an IgG2a(b) response in females. Thus, targeting T-/B-cell interactions should be considered in putative further sex-based translational pharmacology research.

Additionally, in CII-stimulated female rat dLN cell cultures IFN-γ/IL-4 production ratio was shifted towards IFN-γ. Consistently, the serum IgG2a(b)/IgG1 CII-specific antibody ratio was shifted towards an IgG2a(b) response in females. Thus, targeting T-/B-cell interactions should be considered in putative further sex-based translational pharmacology research.",

AB  - Collagen type II-induced arthritis (CIA) in Dark Agouti rats, a model of rheumatoid arthritis (RA), reproduces sexual dimorphism in the incidence and severity of the human disease. Th17 cells are central in the induction/propagation of autoimmune inflammation in CIA and RA. To assess mechanisms underlying this dimorphism in CIA rats, in lymph nodes draining inflamed joints and adjacent tissues (dLNs) from CIA rats of both sexes Th17/CD25+Foxp3+CD4+ T-regulatory cell (Treg) ratio, Th17 cell redifferentiation in functionally distinct subsets and Treg transdifferentiation into IL-17-producing cells (exTregs) were examined. In female rats (developing more severe CIA than their male counterparts) the higher frequency of all Th17 cells (reflecting partly their greater proliferation), followed by the higher frequency of highly pathogenic IFN-γ/GM-CSF-co-producing cells, but lower frequency of less pathogenic/immunoregulatory IL-10-producing cells among them was found. Additionally, compared with male rats, in female rats the lower frequency of Tregs was observed. Moreover, Tregs from female rats exhibited diminished proliferative and suppressive capacity (judging by PD-1 expression) and enhanced conversion into IL-17-producing cells. Given that TGF-β concentration was comparable in collagen-type II-stimulated dLN cell cultures from female and male rats, the shift in Th17/Treg ratio followed by augmented Th17 cell redifferentiation into IFN-γ/GM-CSF-co-producing cells and Treg transdifferentiation into IL-17-producing cells in female rats was associated with increased concentration of IL-6 in female rat dLN cell cultures, and the higher frequency of IL-1β- and IL-23-producing cells among their dLN cells. The lower frequency of IL-10-producing B cells, presumably B regulatory cells (Bregs) could also contribute to the shift in Th17/Treg ratio in female rat compared with male rat dLNs. Consistently, the lower expression of IL-35 (the cytokine promoting Treg expansion directly and indirectly, by favoring Breg expansion and conversion into IL-10/IL-35-producing cells) in female rat dLN cells was detected. Thus, the study identified putative cellular and molecular substrates of the sexual dimorphism in the immunopathogenesis and clinical outcome of CIA and suggested mechanisms to be targeted in females to improve control of Th17 response, and consequently clinical outcome of CIA, and possibly RA.

AB  - Collagen-induced arthritis (CIA) is a frequently used animal model of rheumatoid arthritis, human autoimmune disease that exhibits clear sex bias in incidence and clinical course. Female Dark Agouti rats immunized for CIA showed also greater incidence and higher arthritic score than their male counterparts. The study investigated sex differences in mechanisms controlling the primary immune responses in draining lymph nodes (dLNs), as a factor contributing to this dimorphism. The higher frequencies of CD4 + CD25 + Foxp3- cells, presumably activated effector T (Teff) cells, and IL-17+, IFN-γ + and IL-17 + IFN-γ + T cells were found in female compared with male rat dLNs. However, the frequency of CD4 + CD25 + Foxp3+ T regulatory cells (Treg) did not differ between sexes. Thus, CD4+ Teff cells/Treg ratio, and IL-17+ T cells/Treg and IFN-γ + T cells/Treg ratios were higher in female than in male rats, and among them was found lower frequency of PD-1+ cells. This suggested less efficient control of (auto)immune Th1/Th17 cell responses in female rat dLNs. On the contrary, the frequency of IL-4+ T cells was lower in female than in male rat dLNs. Consistently, the ratio of serum levels of collagen-specific IgG2a (IFN-γ-dependent, with an important pathogenic role in CIA) and IgG1 (IL-4-dependent) was shifted towards IgG2a in female compared with male rats. As a whole, the study suggests that sexual dimorphism in the control of T cell activation/polarization could contribute to sex bias in the susceptibility to CIA. Moreover, the study advises the use of animals of both sexes in the preclinical testing of new drugs for rheumatoid arthritis.

AB  - Cell-based tolerogenic therapy is a promising approach for the treatment of autoimmune diseases and transplant rejection. Regulatory T cells and tolerogenic dendritic cells have been particularly explored in the treatment of various autoimmune disorders in experimental models of disease. Although some of these cells have already been tested in a limited number of clinical trials, there is still a need for preclinical research on tolerogenic cells in animal models of autoimmunity. This review will focus on the relevance of data obtained from studies in experimental animal models for the use of tolerogenic cell-based therapy in humans. Also, perspectives for further improvement of tolerogenic cell preparation towards enhanced suppressive activity and stability of the cells will be discussed.

AB  - To close the gap in our knowledge of sex influence on age-related changes in inflammation-oxidation state in spinal cord (SC) relevant to inflammation/oxidative-stress associated neuropathologies, 2–3 month-old (young) and 18–20 month-old (old) rats, exhibiting increased level of IL-6, a commonly used marker of inflamm-aging, were examined for inflammatory/redox status, and the underlying regulatory networks’ molecules expression. With age, rat SC microglia became sensitized (“primed”), while SC tissue shifted towards mild inflammatory state, with increased levels of proinflammatory IL-1β (key marker of microglial systemic inflammation-induced neurotoxicity), which was more prominent in males. This, most likely, reflected age- and sex-related impairment in the expression of CX3CR1, the receptor for fractalkine (CX3CL1), the soluble factor which regulates microglial activation and diminishes production of IL-1β (central for fractalkine neuroprotection). Considering that (i) age-related changes in SC IL-1β expression were not followed by complementary changes in SC IL-6 expression, and (ii) the reversal in the direction of the sex bias in circulating IL-6 level and SC IL-1β expression, it seems obvious that there are tissue-specific differences in the proinflammatory cytokine profile. Additionally, old male rat SC exhibited greater oxidative damage than female, reflecting, most likely, their lower capacity to maintain the pro-oxidant-antioxidant balance. In conclusion, these findings, apart from highlighting the significance of sex for age-associated changes in SC inflammation-oxidation, may be relevant for understating sex differences in human inflammation/oxidative-stress related SC diseases, and consequently, for optimizing their prevention/therapy.

AB  - The aim of this study was to examine the influence of sex on age-related changes in phenotype and functional capacity of rat macrophages. The potential role of estradiol as a contributing factor to a sex difference in macrophage function with age was also examined. Thioglycollate-elicited peritoneal macrophages derived from the young (2 months old) and the naturally senescent intact middle-aged (16 months old) male and female rats were tested for cytokine secretion and antimicrobial activity (NO and H2O2 production and myeloperoxidase activity). Serum concentration of estradiol and the expression of estrogen receptor (ER)α and ERβ on freshly isolated peritoneal macrophages were also examined. Decreased secretion of IL-1β and IL-6 by macrophages from middle-aged compared to the young females was accompanied with the lesser density of macrophage ERα expression and the lower systemic level of estradiol, whereas the opposite was true for middle-aged male rats. Macrophages in the middle-aged females, even with the diminished circulating estradiol levels, produce increased amount of IL-6, and comparable amounts of IL-1β, TNF-α, and NO to that measured in macrophages from the middle-aged males. Age-related changes in macrophage phenotype and the antimicrobial activity were independent of macrophage ERα/ERβ expression and estradiol level in both male and female rats. Although our study suggests that the sex difference in the level of circulating estradiol may to some extent contribute to sex difference in macrophage function of middle-aged rats, it also points to more complex hormonal regulation of peritoneal macrophage activity in females.

AB  - The study examined (a) whether there is sex difference in spinal cord and plasma oxidative stress profiles in Dark Agouti rats immunised for experimental autoimmune encephalomyelitis (EAE), the principal experimental model of multiple sclerosis, and (b) whether there is correlation between the oxidative stress in spinal cord and neurological deficit. Regardless of rat sex, with the disease development xanthine oxidase (XO) activity and inducible nitric oxide synthase (iNOS) mRNA expression increased in spinal cord, whereas glutathione levels decreased. This was accompanied by the rise in spinal cord malondialdehyde level. On the other hand, with EAE development superoxide dismutase (SOD) activity decreased, while O2− concentration increased only in spinal cord of male rats. Consequently, SOD activity was lower, whereas O2− concentration was higher in spinal cord of male rats with clinically manifested EAE. XO activity and iNOS mRNA expression were also elevated in their spinal cord. Consistently, in the effector phase of EAE the concentration of advanced oxidation protein product (AOPP) was higher in spinal cord of male rats, which exhibit more severe neurological deficit than their female counterparts. In as much as data obtained in the experimental models could be translated to humans, the findings may be relevant for designing sex-specific antioxidant therapeutic strategies. Furthermore, the study indicated that the increased pro-oxidant–antioxidant balance in plasma may be an early indicator of EAE development. Moreover, it showed that plasma AOPP level may indicate not only actual activity of the disease, but also serve to predict severity of its course.

AB  - In the present study, upon showing sexual dimorphism in dimethyl fumarate (DMF) efficacy to moderate the clinical severity of experimental autoimmune encephalomyelitis (EAE) in Dark Agouti rats, cellular and molecular substrate of this dimorphism was explored. In rats of both sexes, DMF administration from the day of immunization attenuated EAE severity, but this effect was more prominent in males leading to loss of the sexual dimorphism observed in vehicle-administered controls. Consistently, in male rats, DMF was more efficient in diminishing the number of CD4+ T lymphocytes infiltrating spinal cord (SC) and their reactivation, the number of IL-17+ T lymphocytes and particularly cellularity of their highly pathogenic IFN-γ+GM-CSF+IL-17+ subset. This was linked with changes in SC CD11b+CD45+TCRαβ− microglia/proinflammatory monocyte progeny, substantiated in a more prominent increase in the frequency of anti-inflammatory phygocyting CD163+ cells and the cells expressing high surface levels of immunoregulatory CD83 molecule (associated with apoptotic cells phagocytosis and implicated in downregulation of CD4+ T lymphocyte reactivation) among CD11b+CD45+TCRαβ– cells in male rat SC. These changes were associated with greater increase in the nuclear factor (erythroid-derived 2)-like 2 expression in male rats administered with DMF. In accordance with the previous findings, DMF diminished reactive nitrogen and oxygen species generation and consistently, SC level of advanced oxidation protein products, to the greater extent in male rats. Overall, our study indicates sex-specificity in the sensitivity of DMF cellular and molecular targets and encourages sex-based clinical research to define significance of sex for action of therapeutic agents moderating autoimmune neuroinflammation-/oxidative stress-related nervous tissue damage.
