Pełny tekst źródłaCirculating immune complexes play an important role in the modulation of antibody responses and in the pathogenesis of immune diseases. This thesis deals with the in vivo regulatory properties of antibodies and their specific Fc receptors.
The immunosuppressive function of IgG is used clinically, to prevent rhesus-negative women from becoming sensitized to rhesus-positive erythrocytes from the fetus. The mechanism behind this regulation is poorly understood but involvement of a receptor for IgG, FcγRII, has been suggested. It is shown in this thesis that IgG and also IgE induce immunosuppression against sheep erythrocytes to a similar extent both in mice lacking all the known Fc receptors as in wild-type animals. These findings imply that antibody-mediated suppression of humoral responses against particulate antigens is Fc-independent and that the major operating mechanism is masking of epitopes.
Immunization with soluble antigens in complex with specific IgG leads to an augmentation of antibody production. The cellular mechanism behind this control is examined here and it is found that the capture of IgG2a immune complexes by a bone marrow-derived cell expressing FcγRI (and FcγRIII) is essential. An analysis of the ability of IgG3 to mediate this regulation indicated that, in contrast, this subclass of IgG augments antibody responses independently of FcγRI (and FcγRIII). These findings suggest that distinct mechanisms mediate the enhancing effect of different subclasses of antibodies.
Finally, the contribution of FcγRIII was studied in the development of collagen-induced arthritis (CIA), an animal model for rheumatoid arthritis in humans. It was discovered that while DBA/1 wild-type control mice frequently developed severe CIA, with high incidence, FcγRIII-deficient mice were almost completely protected, indicating a crucial role for FcγRIII in CIA.
The results presented here help to understand how immune complexes regulate immune responses in vivo and show that Fc receptors for IgG, if involved, could be new targets for the treatment of immune complex-related disorders.

Insects secrete antimicrobial peptides as part of the innate immune response. Most antimicrobial peptides from insects have antibacterial but not antifungal activity. We have characterized an antifungal peptide, diapausin-1 from hemolymph of a lepidopteran insect, Manduca sexta (tobacco hornworm). Diapausin-1 was isolated by size exclusion chromatography from hemolymph plasma of larvae that were previously injected with a yeast, Saccharomyces cerevisiae. Fractions containing activity against S. cerevisiae were analyzed by SDS-PAGE and MALDI-TOF MS/MS and found to contain a 45-residue peptide that was encoded by sequences identified in M. sexta transcriptome and genome databases. A cDNA for diapausin-1 was cloned from cDNA prepared from fat body RNA. Diapausin-1 is a member of the diapausin family of peptides, which includes members known to have antifungal activity. The M. sexta genome contains 14 genes with high similarity to diapausin-1, each with 6 conserved Cys residues. Diapausin-1 was produced as a recombinant protein in Escherichia coli. Purified recombinant diapausin-1 was active against S. cerevisiae, with IC₅₀ of 12 μM, but had no detectable activity against bacteria. Spores of some plant fungal pathogens treated with diapausin-1 had curled germination tubes or reduced and branched hyphal growth. Diapausin-1 mRNA level in fat body strongly increased after larvae were injected with yeast or with Micrococcus luteus. In addition, diapausin-1 mRNA levels increased in midgut and fat body at the wandering larval stage prior to pupation, suggesting developmental regulation of the gene. Our results indicate that synthesis of diapausin-1 is part of an antifungal innate immune response to infection in M. sexta. Biophysical analysis showed that diapausin-1 binds to the β-1,3 glucan component of the S. cerevisiae cell wall. A second insect peptide investigated in this project was M.sexta stress-response peptide 1(SRP1), an immune-related peptide upregulated under different stress conditions including immune-challenge. Preliminary results for NMR structure determination are presented. Most of the amino acid residue spin systems were assigned, and we determined the connectivities of many amino residues as a first step to solve the NMR structure. The circular dichroism spectrum of SRP1 indicates that the peptide lacks alpha-helical structure and may contain beta strands and turns.

Pełny tekst źródłaAn early hallmark of Toxoplasma gondii infection is the rapid control of the parasite population by a potent multifaceted innate immune response that engages resident and homing immune cells along with pro- and counter-inflammatory cytokines. In this context, IFN-γ activates a variety of T. gondii–targeting activities in immune and nonimmune cells but can also con- tribute to host immune pathology. T. gondii has evolved mechanisms to timely counteract the host IFN-γ defenses by interfering with the transcription of IFN-γ–stimulated genes. We now have identified TgIST (T. gondii inhibitor of STAT1 transcriptional activity) as a critical molecular switch that is secreted by intracellular parasites and traffics to the host cell nucleus where it inhibits STAT1-dependent proinflammatory gene expression. We show that TgIST not only sequesters STAT1 on dedicated loci but also promotes shaping of a nonpermissive chromatin through its capacity to recruit the nucleosome remodeling deacetylase (NuRD) transcriptional repressor. We found that during mice acute infection, TgIST-deficient parasites are rapidly eliminated by the homing Gr1+ inflammatory monocytes, thus highlighting the protective role of TgIST against IFN-γ–mediated killing. By uncovering TgIST functions, this study brings novel evidence on how T. gondii has devised a molecular weapon of choice to take control over a ubiquitous immune gene expression mechanism in metazoans, as a way to promote long-term parasitism

Pełny tekst źródłaPARP12 is a protein that possesses three main domains: A putative RNA binding N-terminal domain composed of tandem CCCH zinc-fingers, a central WWE domain and a C-terminal PARP catalytic domain. In this work, we have shown that the expression of PARP12 is strictly-dependent on type-I interferons, that it possesses ADP-ribosyl transferase activity and that in can regulate the translation of messenger RNA into proteins. PARP12 can be found in stress granules, sites of storage of untranslated mRNAs, and is capable of directly inhibiting the translation of a reporter mRNA when tethered to it, in a manner dependent on its catalytic activity. Furthermore overexpression of wild-type PARP12, in contrast to overexpression of a mutant with no detectable catalytic activity (PARP12-G575W), leads to a general arrest of most cellular translation.
On the other hand, we have shown that PARP12 can activate the transcription of genes under the control of an NFκB-dependent promoter, especially when its zinc-fingers are deleted or mutated (PARP12ΔZnF). PARP12ΔZnF is located in structures that can enclose TRIF, RIP1, NEMO, p62/SQSTM1 and ubiquitin. These proteins have all possess an important role in the activation of NFκB signalling cascades. Moreover, we have shown that endogenous PARP12 is situated in ALIS (Aggresome-Like Induced Structures) in LPS-stimulated macrophages. These structures have a possible role in the presentation of antigens on class I major histocompatibility complexes, implying that PARP12 may be involved in the regulation of antigen presentation.

Pełny tekst źródłaRécemment, de nouveaux lymphocytes T auxiliaires ont été décrits, les lymphocytes Th17, producteurs d’IL-17A, d’IL-17F et d’IL-22, d’une part, et les lymphocytes Tfh, sécrétant de l’IL-21 et exprimant CXCR5, ICOS et PD-1, d’autre part. La différenciation des lymphocytes Th17 dépend de la présence d’IL-6 ou d’IL-21 et de TGF-β, et est inhibée par l’IL-4 ;tandis que les lymphocytes Tfh sont induits en présence d’IL-21, d’IL-6 et du répresseur transcriptionnel Bcl6. Alors que les lymphocytes Th17 sont associés à des réponses inflammatoires par le recrutement de neutrophiles, les lymphocytes Tfh aident les lymphocytes B à produire des anticorps de haute affinité.
L’objectif principal de notre travail est l’étude du développement potentiel de réponses de type Th17 chez le nouveau-né de souris soumis à une stimulation allogénique et au manque d’IL-4. De plus, l’existence potentielle de lymphocytes Tfh induits chez le nouveau-né immunisé avec un vaccin constitué d’ovalbumine de poulet et d’Alum, sera investiguée.
Dans notre modèle de tolérance néonatale, l’immunisation de nouveau-nés BALB/c à l’aide de cellules spléniques semi-allogéniques F1 (AJAX x BALB/c) induit une polarisation de type Th2, associée à l’établissement d’un chimérisme lymphoïde et à l’acceptation d’une greffe de peau présentant les alloantigènes rencontrés à la naissance. Des nouveau-nés soumis à cette immunisation allogénique et à la privation d’IL-4, réalisée par l’utilisation d’anticorps monoclonaux ou de souris IL-4-/-, rejettent de façon aiguë les greffons de peau et présentent une proportion réduite de cellules chimériques. Cette rupture de la tolérance néonatale est associée à l’inhibition de la réponse allospécifique de type Th2 et au développement de lymphocytes Th17 alloréactifs, produisant de l’IL-17A. L’inhibition de la voie Th17 ne conduit toutefois pas à l’acceptation des allogreffes de peau. Par contre, la neutralisation de l’IL-6 ou de l’IL-17A et la réduction du nombre de neutrophiles restaurent la proportion de cellules chimériques présentes dans la rate, démontrant que la réponse de type Th17 allospécifique néonatale contrôle le chimérisme lymphoïde.
En réponse au vaccin OVA-Alum, les nouveau-nés présentent une proportion accrue de lymphocytes Tfh CXCR5+ PD-1+, bien que cette proportion lymphocytaire soit significativement diminuée par rapport aux adultes. Les lymphocytes Tfh néonataux expriment en outre des taux moindres des ARNm d’IL-21, d’IL-4 et de Bcl6, suggérant que la génération de lymphocytes Tfh est altérée en début de vie. En parallèle, les titres et la maturation des anticorps produits suite à la vaccination sont réduits chez les nouveau-nés, en comparaison avec les adultes. Cependant, qu’ils soient déficients en IL-4 ou non, des lymphocytes T CD4+ néonataux activés in vitro en présence d’IL-6 induisent une production d’anticorps par des lymphocytes B compétents, suggérant qu’il n’y a pas de défaut intrinsèque des lymphocytes T du nouveau-né à développer une capacité d’aide aux lymphocytes B.
En conclusion, nous avons montré que la polarisation de type Th2 néonatale inhibe la différenciation de lymphocytes Th17 alloréactifs contrôlant le rejet de cellules allogéniques, un mécanisme pouvant intervenir dans la relation immunitaire entre la mère et l’enfant. Nos résultats indiquent également que le nouveau-né est capable de différencier des lymphocytes Tfh, bien que le développement de ces derniers semble réduit. \
