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  - 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.

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.

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  - Multiple sclerosis (MS) is an inflammatory disorder of the central nervous system (CNS)
characterized by infiltration of lymphocytes that leads to myelin damage and neurodegeneration.
The complex interaction between CNS-infiltrating immune cells (CNS-IIC) and astrocytes is an
important contributor to the disease progression. Here, we investigate how naïve astrocytes respond
to autoreactive immune cells present in the CNS at different stages of the disease. For this purpose,
CNS-IICs were isolated from the spinal cords of rats with experimental autoimmune
encephalomyelitis at onset, late-onset and the peak of the disease. Naïve astrocytes, isolated from
the spinal cords of wild-type rat pups, responded to brief bath application of CNS-IIC by robust
elevation of intracellular Ca2+ independently of the disease stage. Our data suggest that direct
contact between astrocytes and CNS-IICs induces Ca2+ changes in astrocytes and points to the new
aspect of cell-cell interactions in the propagation of neuroinflammatory response in CNS
autoimmunity.

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.

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.

U cilju boljeg razumevanja faktora koji utiču na patogenezu MS-e, kao i definisanja novih potencijalnih terapeutika, u ovoj doktorskoj disertaciji je ispitivan efekat sporooslobađajućeg donora vodonik-sulfida, GYY4137, na imunske ćelije uključene u patogenezu eksperimentalnog autoimunskog encefalomijelitisa (EAE), najčešće korišćenog životinjskog modela MS-e. GYY4137 je ostvario jasan antiiflamacijski efekat na BV2 ćelije (ćelijska linija mikroglije), dok je njegov efekat na dendritske ćelije (DĆ) diferentovane iz ćelija kostne srži C57BL/6 miševa bio ograničen. Takođe, GYY4137 nije uticao na procentualnu zastupljenost Th1 i Th17 limfocita, glavnih patogenih populacija T limfocita u patogenezi EAE-a, unutar populacije ćelija poplitealnih limfnih čvorova (PLČ) imunizovanih C57BL/6 miševa i/ili DA pacova, ali je doveo do smanjenja zastupljenosti Th17 limfocita unutar populacije imunskih ćelija izolovanih iz kičmene moždine imunizovanih pacova. S druge strane, ovo jedinjenje je dovelo do smanjenja zastupljenosti regulatornih T limfocita (Treg) unutar populacije ćelija PLČ, ali nije uticalo na njihovu zastupljenost unutar populacije imunskih ćelija izolovanih iz kičmene moždine. Mehanizam kojim je GYY4137 ostvario efekat na zastupljenost Treg unutar populacije ćelija PLČ je obuhvatao smanjenje ekspresije transkripcionog faktora FoxP3, koje je najverovatnije bilo posredovano stimulacijom njegove proteazomalne degradacije. Pored toga, ovo jedinjenje je dovelo do povećanja produkcije reaktivnih vrsta kiseonika u BV2 ćelijama i CD4+ T limfocitima izolovanim iz PLČ imunizovanih miševa. Rezultati ove doktorske disertacije ukazuju na to da GYY4137 ostvaruje imunomodulacijski efekat na imunske ćelije uključene u patogenezu EAE-a, pri čemu priroda i intenzitet ovog efekta zavise od ćelijske populacije na koju se dejstvo ostvaruje, kao i od miljea iz kojeg ćelije potiču.
AB  - Multiple sclerosis (MS) is a chronic, inflammatory, demyelinating, neurodegenerative disease of the central nervous system. The aim of this doctoral dissertation has been to improve knowledge about factors that influence MS pathogenesis and to define new potential MS therapeutics by examination of the effects of slow-releasing hydrogen-sulfide donor, GYY4137, on immune cells involved in the pathogenesis of experimental autoimmune encephalomyelitis (EAE), commonly used MS animal model. Immunomodulatory effect of in vitro treatment with GYY4137 was investigated on BV2 cells (microglial cell line) and dendritic cells (DC) differentiated from bone marrow precursors of C57BL/6 mice. GYY4137 exerted potent anti-inflammatory effects on BV2 cells, while its effects on DC were limited. Further, GYY4137 effect on the percentage of different T cell subpopulations among cells isolated from popliteal lymph nodes (PLN) or spinal cords of immunized C57BL/6 mice and/or DA rats was evaluated. The results showed that, despite having no effect on the percentage of two major pathogenic T helper (Th) cell populations in EAE (Th1 and Th17 cells) among cells from PLN, GYY4137 reduced the percentage of Th17 among immune cells isolated from spinal cords of immunized rats. In contrast to the effect on the percentage of Th17 cells, GYY4137 reduced the percentage of regulatory T cells (Treg) among PLN cells, but not among immune cells obtained from spinal cords of immunized rats. GYY4137 accomplished its effect on the Treg percentage by reducing the relative protein expression of FoxP3, which was probably mediated by stimulation of its proteasomal degradation. Furthermore, GYY4137 potentiated reactive oxygen species generation in BV2 cells and CD4+ T cells isolated from PLN of immunized mice. The results of this doctoral thesis indicate that GYY4137 exerts immunomodulatory effects on immune cells involved in EAE pathogenesis, while the nature and intensity of these effects depend on the cell type and the milieu of cellular origin. Also, these results suggest that GYY4137 has a significant anti-encephalitogenic potential.

AB  - Interaction between autoreactive immune cells and astroglia is an important part of the pathologic processes that fuel neurodegeneration in multiple sclerosis. In this inflammatory disease, immune cells enter into the central nervous system (CNS) and they spread through CNS parenchyma, but the impact of these autoreactive immune cells on the activity pattern of astrocytes has not been defined. By exploiting naïve astrocytes in culture and CNS-infiltrated immune cells (CNS IICs) isolated from rat with experimental autoimmune encephalomyelitis (EAE), here we demonstrate previously unrecognized properties of immune cell-astrocyte interaction. We show that CNS IICs but not the peripheral immune cell application, evokes a rapid and vigorous intracellular Ca2+ increase in astrocytes by promoting glial release of ATP. ATP propagated Ca2+ elevation through glial purinergic P2X7 receptor activation by the hemichannel-dependent nucleotide release mechanism. Astrocyte Ca2+ increase is specifically triggered by the autoreactive CD4+ T-cell application and these two cell types exhibit close spatial interaction in EAE. Therefore, Ca2+ signals may mediate a rapid astroglial response to the autoreactive immune cells in their local environment. This property of immune cell-astrocyte interaction may be important to consider in studies interrogating CNS autoimmune disease.

AB  - The aim of this study was to examine the in vitro effects of the slow-releasing H2S donor GYY4137 on the immune cells involved in the pathogenesis of the central nervous system (CNS) autoimmune disease, multiple sclerosis (MS). GYY4137 specifically potentiated TGF-β expression and production in dendritic cells and significantly reduced IFN-γ and IL-17 production in the lymph node and spinal cord T cells obtained from mice immunized with CNS antigens. Both the proportion of FoxP3+ regulatory CD4+ T cells in the lymph node cells, and the percentage of IL-17+ CD4+ T cells in the spinal cord cells were reduced upon culturing with GYY4137. Interestingly, the peripheral blood mononuclear cells obtained from the MS patients had a lower expression of the H2S-producing enzyme, 3-mercaptopyruvate-sulfurtransferase (MPST), in comparison to those obtained from healthy donors. A significant inverse correlation between the expression of MPST and several pro-inflammatory factors was also observed. Further studies on the relevance of the observed results for the pathogenesis and therapy of MS are warranted.

AB  - Gut microbiota dysbiosis has been considered the essential element in the pathogenesis of multiple sclerosis and its animal model, experimental autoimmune encephalomyelitis (EAE). Antibiotics were administered orally to Dark Agouti (DA) rats early in their life with the aim of perturbing gut microbiota and investigating the effects of such intervention on the course of EAE. As a result, the diversity of the gut microbiota was reduced under the influence of antibiotics. Mainly, Firmicutes and Actinobacteria were replaced by Proteobacteria and Bacteroidetes, while decreased proportions of Clostridia and Bacilli classes were accompanied by an increase in Gamma-Proteobacteria in antibiotic-treated animals. Interestingly, a notable decrease in the Helicobacteraceae, Spirochaetaceae and Turicibacteriaceae was scored in antibiotic-treated groups. Also, levels of short chain fatty acids were reduced in the faeces of antibiotic-treated rats. Consequently, aggravation of EAE, paralleled with stronger immune response in lymph nodes draining the site of immunization, and increased inflammation within the CNS, were observed in antibiotic-treated DA rats. Thus, the alteration of gut microbiota leads to an escalation of CNS-directed autoimmunity in DA rats. The results of this study indicate that antibiotic use in early life may have subsequent unfavourable effects on the regulation of the immune system.

AB  - Dendritic cells (DC) are professional antigen presenting cells that have an important role in inducing the immune response. Under normal conditions, DC reside in peripheral tissues in an immature state. However, they undergo a series of maturation steps in response to inflammatory stimuli. During maturation, DC up-regulate major histocompatibility complex (MHC) class II molecules and co-stimulatory molecules (CD40, CD80, CD86) for antigen presentation and increasingly secrete cytokines. Tolerogenic DC (tolDC) have immunoregulatory properties and are characterized by low expression of MHC class II and co-stimulatory molecules, with limited production of proinflammatory cytokines. TolDC-based immunotherapy is a promising perspective in the treatment of autoimmune diseases. Benfotiamine (S-benzoylthiamine-O-monophosphate) is an S-acyl derivative of vitamin B1 with anti-inflammatory and anti-oxidative properties. Here, we explored the potential of benfotiamine to induce tolerogenic phenotype of DC. DC were cultivated from progenitor bone marrow cells isolated from the femur of C57BL/6 mice. The cells were cultured for 7 days in the presence of granulocyte-macrophage colony-stimulating factor (20 ng/mL) with 100 ng/mL lipopolysaccharide added for the last 24 h of cultivation for maturation. Treatment with benfotiamine (100 μM) was performed on days 0, 2, 4 and 6. FACS analysis showed that benfotiamine applied during differentiation of DC suppressed the expression of MHC class II and CD86, while it did not affect the expression of CD40. The secretion of proinflammatory cytokines TNF, IL-1β, and IL-6 was also decreased. Morphological analysis showed that DC treated with benfotiamine were similar in shape and size to immature DC, despite the maturation stimulus that they were exposed to. The effects of benfotiamine are associated with its suppression of NF-κB translocation to the nucleus. Together, these results show that benfotiamine has the potential to direct DC toward tolDC. Studies on the application of benfotiamine-treated DC in animal models of autoimmunity are warranted.

AB  - Aims: Multiple sclerosis (MS) is an in ammatory autoimmune disorder of the central nervous system (CNS). Complex
interactions between in ltrating immune cells (IIC) and resident glial cells of the CNS cause myelin loss and neuronal dysfunction
in MS. Here we aim to understand how naïve astrocytes functionally respond to the IIC invasion of the CNS.
Methods: We measured calcium activity of naïve astrocytes in culture upon application of IIC. An experimental autoimmune
encephalomyelitis (EAE) MS rat model was used to isolate IIC from the spinal cord of animals at the symptomatic stage. Naïve
astrocytes were isolated from the spinal cord of WT rats.
Results: We show that IIC and not the lymph node immune cells evoke vigorous increase in the astrocyte calcium activity.
This IIC-induced calcium response depends on an autocrine activation of the purinergic P2X7 receptors on the naïve astrocytes.
We also show that IIC induce ATP release from astrocytes by a mechanism that involves gap junctions and/or hemichannels
activation and not the vesicular pathway. Our data indicate that ATP release and subsequent increase in the astrocytic calcium
activity mainly depends on the cell-cell contact between naïve astrocytes and IIC.
Conclusions: These results show that naïve astrocytes functionally respond to the IIC by augmented release of ATP. An increase
in ATP release would alter astrocyte-neuron communication and a ect neuronal function in MS.
