É na maioria dos casos grave e incapacitante, afetando cerca de 2,5 milhões de pessoas em todo mundo. Encefalomielite autoimune experimental (EAE) é um modelo murino de doença autoimune, mediada por linfócitos Th1 e Th17, desenvolvido para o estudo da EM. O protocolo de indução do modelo utiliza o adjuvante completo de Freund (CFA) que contem padrões moleculares associados ao patógeno (PAMPs) que se ligam aos receptores Toll-like (TLRs), expressos em células apresentadoras de antígeno (APC), cruciais para ativação dos linfócitos T. Estes receptores são necessários à indução da EAE, ativando vias de sinalização nas células da imunidade inata e adaptativa, que podem induzir a produção de mediadores pró-inflamatórios, responsáveis pela lesão no SNC, ou mediadores anti-inflamatórios, que podem participar da regulação da doença. O presente estudo avaliou a resposta imune inata na fase inicial de desenvolvimento da EAE em camundongos C57BL/6 imunizados com o peptídeo MOG35-55 (glicoproteína mielínica de oligodendrócitos) e CFA (grupo EAE) ou somente CFA (grupo MOG negativo). Os animais foram sacrificados nos dias 2, 4 e 7 após a indução do modelo. Os linfonodos inguinais e a medula espinhal foram removidos e submetidos à análise histológica, dosagens de citocinas e quimiocinas, assim como avaliação da expressão dos TLRs. Os resultados obtidos indicaram que somente os animais do grupo EAE desenvolveram sinais clínicos da doença. Este grupo também apresentou intenso infiltrado celular na medula espinal no 7º dia após a indução, níveis elevados de quimiocinas CCL5 e CCL20 e citocinas IL-6, IL-12, IL-1β, TNF-α, IFN-γ, IL-17, IL-10 e TGF- β no SNC, além de maior número de APCs expressando TLR3, TLR4 e TLR9. Desta forma, estes dados sugerem que a expressão dos TLRs e a produção das citocinas pró-inflamatórias mostram-se como sendo fatores críticos para a indução da EAE e, o aumento de padrões anti-inflamatórios, ainda nos pontos iniciais do desenvolvimento da doença, sugere o uso destes padrões, como mecanismos de regulação do modelo experimental e, possivelmente da EM. / Multiple sclerosis (MS) is an inflammatory, chronic demyelinating disease of the central nervous system (CNS). It is in most cases severe and disabling, affecting about 2.5 million people worldwide. Experimental autoimmune encephalomyelitis (EAE) is a murine model of autoimmune disease mediated by Th1 and Th17 lymphocytes developed for studying MS. The induction protocol model uses the complete Freund's adjuvant (CFA) containing the pathogen associated molecular patterns (PAMPs) that bind to Toll-like receptors (TLRs) expressed on antigen presenting cells (APC), crucial for activation T lymphocytes. These receptors are necessary for the induction of EAE by activating signal pathways in cells of the innate and adaptive immunity, which can induce the production of pro-inflammatory mediators responsible for the CNS lesions or anti-inflammatory mediators that can participate in the regulation of disease. The present study evaluated the innate immune response in the initial phase of development of EAE in C57BL/6 mice immunized with MOG35-55 peptide (myelin oligodendrocyte glycoprotein) and CFA (group EAE) or CFA alone (group MOG negative). The animals were sacrificed on days 2, 4 and 7 after induction model. The inguinal lymph nodes and spinal cord were removed and subjected to histological, serum cytokines and chemokines, as well as evaluating the expression of TLRs. The results showed that only animals of group EAE developed clinical signs of disease. This group also showed an intense cellular infiltrate in the spinal cord on day 7 after induction, high levels of chemokines CCL5 and CCL20 and cytokines IL-6, IL-12, IL-1β, TNF-α, IFN-γ, IL-17, IL-10 and TGF-β in the CNS, and increased number of APCs expressing TLR3, TLR4 and TLR9. Thus, these data suggest that expression of TLRs and production of pro-inflammatory cytokines are shown as being critical for the induction of EAE, and increased anti-inflammatory patterns, still in the initial points of development of the disease, suggests the use of these patterns as regulation mechanisms of the experimental model and possibly the MS.

Les infections et l’activation du système immunitaire stimulent l’hématopoïèse. L’activation des récepteurs Toll-like (TLRs) des cellules souches hématopoïétiques, par leur reconnaissance de motifs moléculaires portés par des agents infectieux, en oriente la différenciation vers les voies myéloïdes, renforçant la capacité de notre organisme à lutter contre les infections. Ici, nous avons étudié si les agonistes TLRs peuvent, au contraire, induire au sein de la moelle osseuse l’émergence de progéniteurs hématopoïétiques présentant des propriétés immunorégulatrices. Nous montrons que l’incubation de moelle osseuse de souris en présence de l’agoniste TRL-9, CpG-B, entraîne l’émergence d’une population de progéniteurs au stade pro-B (appelée CpG-proBs). Le transfert adoptif de seulement 60,000 CpG-proBs par receveur, à l’apparition des premiers signes cliniques, confère une protection à long terme dans deux modèles expérimentaux de maladies auto-immunes, le Diabète de Type I (T1D) et l’Encéphalomyélite Auto-immune Expérimentale (EAE). La migration, la différenciation, et les mécanismes cellulaires et moléculaires de cette population protectrice sont décrits et comparés entre ces deux modèles. Dans les deux modèles, les CpG-proBs migrent vers le tissu cible de la réponse auto-immune et se différencient en cellules B matures régulatrices. Dans le T1D, l’interféron-γ (IFN-γ) produit par les cellules T s’avère essentiel pour induire la surexpression de FasL à la surface des CpG-proBs, entraînant l’apoptose des cellules T effectrices. De plus, l’IFN-γ produit par les CpG-proBs réduit la production par les cellules T de l’IL-21, une cytokine pathogène majeure dans le T1D. La descendance des CpG-proBs est composée de précurseurs transitionnels B, de cellules B de la zone marginale et de cellules B folliculaires, exprimant de forts niveaux de FasL et toujours capables d’induire l’apoptose des cellules T, prolongeant ainsi le contrôle des cellules effectrices T auto-immunes in vivo. Dans l’EAE, l’IFNγ est indirectement responsable de la rétention des cellules T, par l’internalisation de CCR7, au sein des ganglions lymphatiques, inhibant ainsi leur migration au système nerveux central (SNC). Dans la moelle épinière, tissu cible de l’EAE, les CpG-proBs se différencient en cellules B220+CD5+CD1dhiCD11b+, secrétant la cytokine anti-inflammatoire IL-10. Enfin, la mobilisation des progéniteurs hématopoïétiques par un cocktail de facteurs hématopoïétiques confère à une sous-population multipotente au stade MPP2 la propriété d’augmenter l’expansion des Foxp3+ Tregs et de prévenir la survenue du diabète de type 1. Nous montrons que les MPP2 mobilisés s’avèrent également capables d’exercer un effet protecteur envers l’EAE. Leur capacité à induire l’expansion de Treg Foxp3+ au sein du SNC et à la périphérie joue un rôle essentiel dans la protection des souris envers l’EAE, puisque la déplétion des Treg abolit la protection déjà établie. Pour conclure, nous avons mis en évidence que diverses stimulations de l’hématopoïèse induisent l’émergence de nouvelles populations de progéniteurs hématopoïétiques qui présentent des propriétés immunorégulatrices et constituent de nouveaux outils de thérapie cellulaire des maladies auto-immunes. / It is well known today that various infectious events or other stimuli of the immune system can trigger hematopoiesis. The hematopoeitic stem and/or progenitor cells express on their cell surface Toll-like receptors which can recognize molecular motifs of infectious agents. The stimulation of TLRs on hematopoietic stem cells favors their differentiation into myeloid lineages, reinforcing the capacity of our body to fight against the pathogens. Herein, we have investigated whether the stimulation of TLRs can induce, instead, the emergence within the bone marrow of selective progenitor cells with immunoregulatory properties. We show that incubation of bone marrow cells with the TLR-9 ligand CpG-B can induce a pro-B cell population (named CpG-proBs) whose adoptive transfer at low numbers of 60,000 cells provided long-lasting protection in two models of autoimmune diseases, Type I Diabetes (TID) and Experimental Autoimmune Encephalomyelitis (EAE) at the onset of clinical signs. The migration, differentiation and molecular mechanism of action of this protective population is described and compared between these two models. In both models, the CpG-proBs migrate to the target tissue of autoimmune responses and differentiate into more mature regulatory B cells. In TID, IFN-γ produced by both T and CpG-proB cells is essential for the upregulation of FasL at the surface of CpG-proBs, inducing the apoptosis of the effector T cells. In addition, IFN-γ reduced the T-cell production of IL-21, a major pathogenic cytokine in TID. The progeny of the adoptively transferred CpG-proBs, including transitional precursors B cells, marginal zone and follicular B cells, display high expression of FasL, promote apoptosis of effector T cells and prolong the control of autoimmune effector T cells in vivo. In EAE, IFN-γ was responsible for the restriction of T cells to the lymph nodes, inhibiting their homing to the CNS. IFN-γ indirectly induced the internalization of CCR7, a receptor required for the migration across the blood-brain barrier. In the spinal cord (target tissue in EAE), CpG-proBs differentiated into B220+CD5+CD1dhiCD11b+ cells secreting the anti-inflammatory cytokine IL-10. Finally, hematopoietic progenitor populations mobilized to the periphery by a cocktail of G-CSF and Flt3l, at the stage of MPP2, have already been shown to protect against TID by expanding the Foxp3+ Tregs. We evaluated them in the EAE model, showing that the ability of these mobilized progenitor cells to trigger the expansion of Foxp3+ Treg within the CNS and the periphery was necessary for providing protection to EAE mice since Treg depletion abrogated the protection once established. In conclusion, we provide evidence for the emergence of new populations of hematopoietic progenitor cells which can display immunoregulatory properties and might be used for cell therapy of autoimmune diseases.

Das Ausmaß der permanenten klinischen Defizite bei Multiple-Sklerose-Patienten entsteht durch axonale Schädigung und axonalem Verlust. In dieser Studie wird eine entscheidende Rolle des niedrigaffinen Neurotrophinrezeptors p75NTR in Bezug auf axonale Schädigung in der experimentellen autoimmunen Encephalitomyelitis (EAE) gezeigt. Nach EAE Induktion per aktiver Immunisierung mit dem Myelin-Oligodendrozyten-Glykoprotein-Peptid MOG35-55 zeigten p75NTR KO Mäuse einen verschlechterten Krankheitsverlauf, stärkere Demyelinisierung und erhöhte axonale Schädigung. Um festzustellen, ob die erhöhten Defizite von einer aggressiveren Inflammation oder von einem vulnerableren zentralen Nervensystem (ZNS) stammen, wurden das Immunsystem während der peripheren Krankheitsentstehung und der darauffolgenden Krankheitsphase und Zellen des ZNS in vivo, ex vivo und in vitro untersucht. Es wurde kein Unterschied in der Qualität der Inflammation mit Hilfe von immunohistochemischen, durchfluss-zytometrischen, ELISA- und mRNA-Analysen gefunden, wodurch eine entscheidende Rolle der untersuchten Immunzellpopulationen ausgeschlossen werden kann. Notzdestrotrotz legt die konstitutive Expression von p75NTR auf B-Zellen eine Rolle für p75NTR während der Generation der Immunantwort innerhalb der Lymphknoten nahe, da p75NTR KO Mäuse von Anfang an einen erhöhten Krankheitsverlauf zeigten. Um die Effekte der p75NTR-Defizienz während des peripheren Primings zu umgehen, wurde die EAE auch durch adoptiven Transfer eines encephalitogenen MOG35-55-spezifischen T-Zell-Klones in p75NTR KO und Wildtyp (wt) Mäusen iduziert. Sie zeigten ähnliche Inzidenz, Beginn und Kinetik der Krankheit. Ein vergleichbares Ausmaß und eine vergleichbare Qualität der Inflammation wurde mit immunohistochemischen und mRNA-Analysen in beiden Mausstämmen am Höhepunkt der Krankheit gefunden. Nichtsdestotrotz leideten p75NTR KO Mäuse an signifikant erhöhten Krankheits-Scores in der chronischen Phase infolge von erhöhtem axonalen Schaden und Verlust. Dies deutet auf eine protektive Rolle von p75NTR im ZNS hin. In dieser Arbeit wird gezeigt, dass Astrozyten, aber nicht Mikroglia, p75NTR konstitutiv exprimieren. Jedoch wurde keine p75NTR-mediierte Regulation von Cytokinen/Chemokinen und der Produktion von reaktiven Sauerstoff-Spezies in vitro gefunden. Aktive Immunisierung von Knochenmark-Chimären, in denen nur Immun- oder ZNS-Zellen einen funktionierenden p75NTR tragen, bestätigen diese Resultate. Während p75NTR KO in wt- und wt in p75NTR KO-Chimären im Vergleich zu wt in wt-Chimären unter einem stärker ausgeprägten Krankheitsverlauf am Höhepunkt der Krankheit leideten, zeigten nur wt in p75NTR KO-Tiere erhöhten axonalen Schaden und Verlust. Zusammengefaßt deuten diese Daten darauf hin, dass p75NTR-Defizienz zu einer aggressiveren peripheren Immunantwort führt (namentlich durch B-Zellen). Desweiteren hat p75NTR auch neuroprotektive Eigenschaften innerhalb des ZNS (namentlich auf Neuronen) unter experimentellen inflammatorischen Bedingungen im ZNS.

Angeborene lymphoide Zellen (ILCs) sind sich im Gewebe befindliche Zellen, die eine wichtige Rolle bei der Aufrechterhaltung der Gewebehomöostase spielen. ILCs wurden in verschiedenen Organen untersucht. Ob ILCs im zentralen Nervensystem (ZNS) vorhanden sind und wenn ja, welchen ​​Phänotyp und welche funktionellen Eigenschaften sie in diesem Organ aufweisen, sind Fragen, die bisher unbeantwortet blieben. NK-Zellen sind die seit langem bekannten ILC-Mitglieder, die viele Merkmale mit ILC1s teilen. Im Zusammenhang mit der Autoimmunität wurde gezeigt, dass NK-Zellen eine immunmodulatorische Rollen spielen. Anhand des Tiermodells von Multiple Sklerose, der experimentellen autoimmunen Enzephalomyelitis, zeigte unsere Gruppe, dass reife NK-Zellen auf CX3CR1-abhängige Weise in das ZNS rekrutiert werden. Auf der Grundlage dieser Beobachtungen will ich in meinem PhD Projekt die Chemokinrezeptoren definieren, die die Rekrutierung der unreifen NK-Zellen in das entzündete ZNS vermitteln. Des Weiteren will ich herausfinden, ob die phänotypisch definierten NK-Zellen (CD3-NK1.1 + -Zellen) die im gesunden ZNS vorhanden sind, echte NK-Zellen sind, oder sie zu den ILC1s gezählt werden können. Die Ergebnisse der vorliegenden Arbeit zeigen, dass die im gesunden ZNS vorhandenen CD3-NK1.1+ -Zellen verschiedene Typ-1-ILC-Subsets umfassen: NK-Zellen, ILC1s, Intermediat-ILC1s und Ex-ILC3s. CXCR3 wurde auf ILC1s und einer Fraktion von unreifen NK-Zellen exprimiert, trug jedoch nicht zur Rekrutierung von NK-Zellen in das ZNS im EAE-Modell bei. Die Expression von CD49a, CD69, CXCR6, DNAM-1high, TRAIL und CD200R und das Fehlen von Eomes unterschieden die ILC1 von den NK-Zellen im ZNS. Zusätzlich ILC1s sezernierten mehr TNF-α als NK-Zellen. ILC1s waren die dominante Typ-1-ILC Subgruppe im Plexus choroideus und im Gehirnparenchym und waren auch in den Meningen vorhanden. Zusammenfassend bietet die vorliegende Arbeit zum ersten Mal eine umfassende Charakterisierung von ILCs des Typs I im ZNS. / Innate lymphoid cells (ILCs) are tissue resident cells that play important roles in the maintenance of tissue homeostasis. ILCs have been characterized in diverse organs like the gut and liver. However, whether ILCs are present in the central nervous system (CNS) and if so, what are their phenotype and function in this organ are questions that remain unanswered. NK cells are the longer-known ILC members that share many phenotypical and functional features with ILC1s. Using the animal model of MS, the experimental autoimmune encephalomyelitis (EAE), our group showed that protective mature NK cells are recruited to the CNS on an CX3CR1-dependent manner. Based on that observations, my PhD project aimed to 1) define the chemokine receptors that mediate the recruitment of the immature NK cells into the inflamed CNS and to 2) determine whether the phenotypically defined NK cells (CD3-NK1.1+ cells) that are present in the CNS during steady state constitute bona fide NK cells or constitute also other group 1 ILC subsets. The results of this work indicate that the CD3-NK1.1+ cells present in the healthy CNS comprise diverse group 1 ILC subsets that include conventional NK cells, ILC1s, intermediate-ILC1s and ex-ILC3s. CXCR3 was expressed on ILC1s and a fraction of immature NK cells, but did not contributed to the recruitment of NK cells into the CNS in the EAE model. In addition, the phenotypic and functional characterization of the newly identified CNS-ILC1s is described. The exclusive expression of CD49a, CD69, CXCR6, DNAM-1high, TRAIL and CD200R, and lack of Eomes distinguished the ILC1s from the NK cells in the CNS. IILC1s secreted IFN-γ and more TNF-α than NK cells upon stimulation in the healthy and EAE mice and were the dominant group 1 ILC subset in the choroid plexus and brain parenchyma and were also present in the meninges. In sum, the present work provides for the first time a comprehensive characterization of group 1 ILCs in the CNS.

The events that trigger an autoimmune disease remain largely unknown. To study these events animal models are necessary because symptoms of autoimmune diseases are preceded by a long asymptomatic period in humans. Experimental autoimmune encephalomyelitis (EAE) is the best characterized model for cell mediated autoimmunity and an animal model for the human disease multiple sclerosis. EAE is induced in rodents by immunization with myelin antigens (Ags) together with adjuvants. After immunization, T cells are primed in the periphery by Ag presenting cells and subsequently invade the central nervous system where they mediate parenchymal inflammation, resulting in demyelination and clinical symptoms of an ascending paralysis. It is now generally recognised that the main cell type mediating EAE is the T helper type 17 (Th17) cell. Tolerance to EAE can be attained by DNA vaccination, but how the immune response against the myelin Ags is abrogated after DNA vaccination is not known. By employing short interfering RNA technology, induction of the innate immune signalling molecule interferon (IFN) -β was found to be necessary for the protective effect of DNA vaccination in EAE. In addition, DNA vaccination inhibited subsequent autoimmune Th17 cell responses. The Toll-like receptors (TLRs) of the innate immune system have evolved to recognise conserved molecular structures on microbes and signalling through them almost exclusively converge on the molecule MyD88. Signalling via MyD88 was found to be required for induction of EAE since mice deficient in this molecule did not develop disease. Upstream signalling via TLR4 and TLR9 had tolerogenic properties. In studies of Ag presentation in EAE, two major subtypes of dendritic cells (DCs) were examined. Plasmacytoid DCs were found to have a promoting role in the induction of EAE, partly via type 1 IFNs. Myeloid DCs had a redundant role in the induction phase of EAE, neither disease severity nor encephalitogenic Th17 responses were affected by their absence during priming. These studies further demonstrate that the cells and molecules of the innate immune system exhibit a crucial role in controlling the adaptive immune system which mediates tissue damage in autoimmune diseases.

Vaccination with DNA encoding the encephalitogenic autoantigen myelin oligodendrocyte glycoprotein (MOG), pMOG91-108, induce a protective immunity against experimental autoimmune encephalomyelitis (EAE), an animal model of human multiple sclerosis. By injection of a DNA vaccine that contains a DNA region encoding short interfering RNA specific for IFNβ (pMOG-IFNβ) the protective effect of the DNA vaccination is totally inhibited. This demonstrates that IFN-β is directly involved in the protective mechanism against EAE. The objective of this project was to study how molecules involved in the inflammatory process in EAE are regulated by suppressive DNA vaccination. mRNA expression of IL-1β, TGF β, IL-23p40 and Axl receptor tyrosine kinas did not show any significant differences between the groups vaccinated with these DNA vaccines. IL-6 and IFNγ mRNA expression after MOG stimulation in rats treated with pCI, a control vaccine was significantly higher compared to the group vaccinated with vaccine containing pMOG-IFNβ. IL-17 m RNA expression after MOG stimulation in pCl-treated rats was significantly higher compared to the group vaccinated with vaccine containing pMOG-91-108. Of these results the mRNA expression of IL-17 and IL-6 were of interest for the project.

L'inhibition du protéasome a un effet anti-inflammatoire en bloquant l'activation de NF-êB. Dans ce travail, nous avons étudié cette propriété anti-inflammatoire dans deux modèles animaux de maladies neurologiques: la sclérose en plaques et l'AVC. Nous avons utilisé le ritonavir, un antiprotéase du VIH et qui a des effets de modulation sur le protéasome. Ainsi l'administration du ritonavir a permis d'inhiber l'EAE modèle animal de SEP. D'autre part, un effet anti-ischémique cérébral a été obtenu ches les animaux ayant subi une occlusion de l'artère cérébrale moyenne, modèle animal d'AVC. Ces effets neuroprotecteurs ont été corrélés à une inhibition de la réponse inflammatoire chez les animaux traités. Ces résultats ouvrent des nouvelles perspectives thérapeutiques dans les maladies inflammatoires basées sur la modulation du protéasome
