IL-23 Promotes TCR-mediated Negative Selection of Thymocytes through the Upregulation of IL-23 Receptor and RORγt
Transient thymic involution is frequently found during inflammation, yet the mode of action of inflammatory cytokines is not well defined. Here we report that interleukin-23 (IL-23) production by the thymic dendritic cells (DCs) promotes apoptosis of the CD4(hi)CD8(hi) double-positive (DP) thymocytes. A deficiency in IL-23 signalling interferes with negative selection in the male D(b)/H-Y T-cel...
متن کاملCytokines (IL-17, IL-23, and IL-33) in Systemic lupus erythematosus in Trinidad and Tobago.
Systemic lupus erythematosus (SLE) is the most common autoimmune disease. It is characterized by the presence of hundreds of autoantibodies against many organs and tissues, including the presence of a large number of autoantibodies, which are specific to self-antigens mainly of nuclear origin such as Smith antigen, double-stranded DNA (dsDNA), anti-Sjögren’s syndrome-related antigen A and B (SS...
متن کاملIL-23 Gene and Protein Expression in Childhood Asthma
Background: Asthma is the chronic inflammation of airways characterized by eosinophilic infiltration, mucus overproduction, airway hyper-responsiveness and airway remodeling. These changes are induced mostly by cytokines which are produced by T helper (Th) 2 cells. Recently, the role of interleukin-23 (IL-23) in the pathogenesis of adultallergic asthma has been studied. Objective: To explore IL...
متن کاملRole of IL-12 in intrathymic negative selection.
Cytokines are central regulatory elements in peripheral lymphocyte differentiation, but their role in T cell ontogeny is poorly defined. In the present study, we evaluated the role of IL-12 in thymocyte selection more directly by determining its role in two models of in vivo negative selection. In initial studies we demonstrated that abundant intrathymic IL-12 synthesis occurs during OVA peptid...
متن کاملIL-23/IL-27 Ratio in Peripheral Blood of Patients with Breast Cancer
Background: Interleukin (IL)-23 and IL-27 are two IL-12-related cytokines which their function may dramatically influence the inflammatory response to tumor development. IL-12 and IL-27 seem to have antagonistic roles with IL-23 in tumor site. In this study, IL-23 and IL-27 mRNA expressions were analyzed in peripheral blood of patients with breast cancer and healthy volunteers using quantitativ...
