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  - Acute respiratory distress syndrome (ARDS) became a focus of intensive research due to its death toll during the Covid-19 pandemic. An uncontrolled and excessive inflammatory response mediated by proinflammatory molecules such as high mobility group box protein 1 (HMGB1), IL-6, and TNF mounts as a response to infection. In this study, ethyl pyruvate (EP), a known inhibitor of HMGB1, was tested in the model of murine ARDS induced in C57BL/6 mice by intranasal administration of polyinosinic:polycytidylic (poly(I:C)). Intraperitoneal administration of EP ameliorated the ARDS-related histopathological changes in the lungs of poly(I:C)-induced ARDS and decreased numbers of immune cells in the lungs, broncho-alveolar lavage fluid and draining lymph nodes (DLN). Specifically, fewer CD8+ T cells and less activated CD4+ T cells were observed in DLN. Consequently, the lungs of EP-treated animals had fewer damage-inflicting CD8+ cells and macrophages. Additionally, the expression and production of proinflammatory cytokines, IL-17, IFN-γ and IL-6 were downregulated in the lungs. The expression of chemokine CCL5 which recruits immune cells into the lungs was also reduced. Finally, EP downregulated the expression of HMGB1 in the lungs. Our results imply that EP should be further evaluated as a potential candidate for ARDS therapy.

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  - Type 1 diabetes (T1D) is an autoimmune disease that leads to the death of insulin-producing
pancreatic β-cells. The autoimmune response in T1D becomes chronic as a consequence of
regulatory mechanisms unable to counteract this disease. In this study, we evaluated the
anti-diabetic potential of a new hybrid compound (HYCO-3) consisting of a CO-releasing
molecule conjugated to a fumaric ester derivative that is known to activate the Nrf2 and
increase the expression of the CO-producing enzyme heme oxygenase-1. T1D was induced
in C57BL/6 mice treated intraperitoneally for 5 consecutive days with multiple low doses of
streptozotocin (40 mg/kg BW). HYCO-3 (25 mg/kg BW daily) was administered by oral
gavage while the control group received the vehicle (DMSO/sesame oil) for 14 days, starting
on the first day of streptozotocin treatment. To evaluate the development of T1D, glycaemia
and body mass were measured weekly. At the end of the experiment the pancreas was
collected and histochemical analyses for insulin expression were performed. Insulitis, the
infiltration of immune cells in the pancreas, was also assessed. We found that treatment
with HYCO-3 lowered blood glucose levels compared to the control group in association
with a lower insulitis grade and a higher expression of insulin in pancreatic islets.
Furthermore, to assess the effect of HYCO-3 on antigen specific response, cells from the
draining pancreatic lymph nodes of diabetic animals were stimulated with insulin and
HYCO-3 to assess the production of pro-inflammatory markers in cell supernatants. HYCO-
3 was able to down-regulate the production of IL-17 in the cultures where antigen specific
response was induced with insulin.
Overall, our results show that HYCO-3 ameliorated T1D in C57BL/6 mice by inhibiting the
recruitment of immune cells into the pancreas. These results warrant future investigation of
cellular and molecular mechanisms by which HYCO-3 acts on immune cells that are of
importance in the pathogenesis of T1D.

AB  - HYCOs are a novel class of hybrid compounds consisting of fumaric esters conjugated to
carbon monoxide-releasing molecules (CO-RMs). They were designed based on the
consideration that fumaric esters are known to activate the transcription factor Nrf2 and that
CO possesses potent anti-inflammatory properties. The dual action of these hybrids has
shown promising therapeutic effects. in animal models of psoriasis and multiple sclerosis.
We have recently started with the group of Drs Motterlini and Foresti in France a
collaborative research project relevant to the BenBedPhar COST Action, focusing on the
immunomodulatory effects of HYCOs. These effects were examined in vitro in cultures of
myeloid-derived cells (macrophages and dendritic cells), lymph node cells, immune cells
isolated from the inflamed central nervous system, and microglia. By assessing the
production of immunoactive molecules, including nitric oxide, reactive oxygen species and
cytokines, we provide evidence that HYCOs display immunomodulatory effects in all cell
populations examined in vitro. Moreover, we were able to demonstrate that HYCOs are
efficient in ameliorating type 1 diabetes in an animal model of this autoimmune disease. Our
results indicate that HYCOs are Nrf2 activators with promising immunomodulatory
therapeutic properties.

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  - 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.

abstract = "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  - Rosmarinic acid is a polyphenolic compound, abundantly presentin herbs of the Lamiaceae
family. The aim of the study was to evaluate a recently developed rosmarinic acid
derivative (RAd), with an enhanced ability of diffusion through biological membranes 1, in
preclinical settingsof the central nervous system autoimmunity. To this extent,
experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis
was used. EAE was induced in DA rats by subcutaneous injection of autologous spinal
cord homogenate 2, while treatment with RAd (30 mg/kg) started at 7 day post
immunization and lasted for 15 days. Subcutaneous RAd administration successfully
ameliorated EAE, leading to abbreviation of the disease duration and reducement of
maximal, cumulative and meanclinical score. Also, RAd effects on draining lymph node
cells (DLNC) isolated in the inductive phase of EAE and spinal cord immune cells (SCIC)
obtained at the peak of the diseasewere evaluated. In vitro treatment with RAd (5 μM)
reduced production of major encephalitogenic cytokines, i.e.interferon (IFN)-γ and
interleukin (IL)-17, both in DLNC and SCIC. The reduction of IFN-γ and IL-17
production under the influence of RAd was also detected in the CD4+ T cells purified
fromDLNC, thus suggesting that RAd had a direct effect on CD4+ T cells. Additionally,
the effects of in vitro treatment with RAd were examinedon macrophages (Mf), immune
cells with important role in EAE pathogenesis. Treatment of peritoneal Mf,obtained from
non-immunized DA rats, with RAd (25 μM) led to reduction of NO and IL-6 production,
exterted no effect on IL-1beta production, and elevated tumor necrosis factor production in
Mf. Expression of MHC II and co-stimulatory molecule CD80, the phagocytic ability and
the production of reactive oxygen species in RAd-treated Mf were also downregulated.
Our results imply that RAd possesses anti-inflammatory and antiencephalitogenicproperties. Thus, further studies on the mechanisms behind the observed
effects and their relevance for the therapy of multiple sclerosis are warranted.

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.

A novel rosmarinic acid derivative (RAd) has been developed and tested in the animal model of type 1 diabetes (T1D) and the animal model of multiple sclerosis, experimental autoimmune encephalomyelitis (EAE). T1D was induced in male C57BL/6 mice using streptozotocin that was applied intraperitoneally for five consecutive days. EAE was induced in Dark Agouti (DA) rats by subcutaneous injection of autologous spinal cord homogenate. For T1D, intraperitoneal administration of RAd (10 mg/kg bw) began from the first streptozotocin injection and continued for 20 days, while for EAE, subcutaneous administration of RAd (28 mg/kg bw) started with the first clinical signs of the disease and continued for 15 days. RAd‐treated mice exhibited lower incidence of T1D (monitored up to 45 days from the disease induction), and fluorescent histochemical analysis showed that their pancreatic islets expressed more insulin. Additionally, RAd ameliorated EAE in DA rats. In T1D, RAd treatment significantly down‐regulated the proportions of CD11b⁺ and CD11c⁺ myeloid cells in the immune cell infiltrates in the pancreas, detected on day 10 after T1D induction. However, the proportions of cells of adaptive immunity (CD4⁺, CD8⁺, Th1, Th17) were comparable between the groups. These results suggest that chemically modified RA shows great promise for anti‐inflammatory approaches in autoimmune and inflammatory diseases, while our previous research illustrated that unmodified RA exerted no effect on T1D pathogenesis.

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.
