Psoriasis is a T-cell-mediated autoimmune disease involving the skin. Two cytokines, interleukin-12 (IL-12) and IL-23 have been shown to play a pivotal role in the pathogenesis of the disease. Ustekinumab (Stelara) is a therapeutic monoclonal antibody (mAb) targeted against the p40 shared subunit of IL-12 and IL-23. Recently the ability of therapeutic proteins (TP) including mAbs that target ei...
Aberrant cytokine expression has been proposed as an underlying cause of psoriasis, although it is unclear which cytokines play critical roles. Interleukin (IL)-23 is expressed in human psoriasis and may be a master regulator cytokine. Direct intradermal administration of IL-23 in mouse skin, but not IL-12, initiates a tumor necrosis factor-dependent, but IL-17A-independent, cascade of events r...
Cutting edge: IL-23 receptor gfp reporter mice reveal distinct populations of IL-17-producing cells.
IL-23, an IL-12 family member, has been implicated in the development of Th17 cells and the progression of autoimmune diseases. However, due to the lack of availability of sensitive Ab reagents specific for the IL-23 receptor (IL-23R), it has been difficult to characterize the cell types that express the IL-23R and are responsive to IL-23 in vivo. To address the role of IL-23 in vivo, we have g...
OBJECTIVE Cytokines are believed to have a role in the pathophysiology of major depression. The alteration in levels of pro-inflammatory cytokines [interleukin 1β (IL-1β), IL-2, IL-6, IL-12, interferon γ, and tumor necrosis factor α] in major depression supports the cytokine hypothesis of this illness. IL-23 and IL-17 are also pro-inflammatory cytokines, but few studies have focused on their ro...
Cathelicidin LL37 is overexpressed in plaques psoriasis. Microbial ligands are part of the triggers over-expression. [Our objectives were] to assess expression LL37, interleukins 17 and 23 skin ex vivo submitted a microbial ligand, then effects AGH8 (vegetal extract) same model. Human explants were ligand: zymosan A at 1% was applied surface on day 0, D2, D3 D6. topically after removal zymosan-...
IL-12 and IL-23 are produced by activated antigen-presenting cells but the two induce distinct immune responses by promoting Th1 and Th17 cell differentiation, respectively. IL-23 is a heterodimeric cytokine consisting of two subunits: p40 that is shared with IL-12 and p19 unique to IL-23. In this study, we showed that the production of IL-23 but not IL-12 was negatively regulated by protein ph...
Objective(s): Systemic lupus erythematosus (SLE) is a multi-factorial autoimmune disease which may be characterized by T lymphocytes dysfunctions. Th17 cells have been identified as new effector cells, which play an important role in the pathogenesis. In recent years, immunomodulatory effect of vitamin D3 has been noticed. In the present experiment, the effect of vitamin D3 on the expression of...
