abstract = {Interleukin (IL)-36 cytokines belong to the IL-1 family and include three agonists, IL-36 α, β and γ and one inhibitor, IL-36 receptor antagonist (IL-36Ra). IL-36 and IL-1 (α and β) activate similar intracellular pathways via their related heterodimeric receptors, IL-36R/IL-1RAcP and IL-1R1/IL-1RAcP, respectively. However, excessive IL-36 versus IL-1 signaling induces different phenotypes in humans, which may be related to differential expression of their respective receptors. We examined the expression of IL-36R, IL-1R1 and IL-1RAcP mRNA in human peripheral blood, tonsil and skin immune cells by RT-qPCR. Monocyte-derived dendritic cells (MDDC), M0, M1 or M2-polarized macrophages, primary keratinocytes, dermal macrophages and Langerhans cells (LC) were stimulated with IL-1β or IL-36β. Cytokine production was assessed by RT-qPCR and immunoassays. The highest levels of IL-36R mRNA were found in skin-derived keratinocytes, LC, dermal macrophages and dermal CD1a(+) DC. In the blood and in tonsils, IL-36R mRNA was predominantly found in myeloid cells. By contrast, IL-1R1 mRNA was detected in almost all cell types with higher levels in tonsil and skin compared to peripheral blood immune cells. IL-36β was as potent as IL-1β in stimulating M2 macrophages, keratinocytes and LC, less potent than IL-1β in stimulating M0 macrophages and MDDC, and exerted no effects in M1 and dermal macrophages. Levels of IL-1Ra diminished the ability of M2 macrophages to respond to IL-1. Taken together, these data are consistent with the association of excessive IL-36 signaling with an inflammatory skin phenotype and identify human LC and M2 macrophages as new IL-36 target cells.},

abstract = {Retro-inverso peptides which contain NH-CO bonds instead of CO-NH peptide bonds are much more resistant to proteolysis than L-peptides. Moreover, they have been shown recently to be able to mimic natural L-peptides with respect to poly- and monoclonal antibodies (Guichard, G., Benkirane, N., Zeder-Lutz, G., Van Regenmortel, M. H. V., Briand, J. P., and Muller, S. (1994b) Proc. Natl. Acad. Sci. U.S.A. 91, 9765-9769). We have further tested the capacity of retro-inverso peptidomimetics to serve as possible targets for antibodies produced by lupus mice and by patients with rheumatic autoimmune diseases. Several retro-inverso peptides corresponding to sequences known to be recognized by autoantibodies were synthesized, namely peptides 28-45 and 130-135 of H3, 277-291 of the Ro/SSA 52-kDa protein, and 304-324 of the Ro/SSA 60-kDa protein, and tested with autoimmune sera by enzyme-linked immunosorbent assay. We have found that retro-inverso peptides are recognized as well as or even better than natural peptides by antibodies from autoimmune patients and lupus mice. This new approach may lead to important progress in the future development of immunodiagnostic assays, particularly in the case of diseases characterized by inflammatory reactions in the course of which the level of degradative enzymes is increased.},
