Differential regulation of interleukin-12 (IL-12)/IL-23 by Tim-3 drives T(H)17 cell development during hepatitis C virus infection.
Cytokine production by innate immunity is critical for shaping the adaptive immunity through regulation of T cell differentiation. In this report, we studied T cell immunoglobulin mucin domain protein 3 (Tim-3) expression on monocytes and its regulatory effect on interleukin-12 (IL-12)/IL-23 production by CD14(+) monocytes, as well as IL-17 production by CD4(+) T cells in individuals with chron...
متن کاملTim-3 pathway controls regulatory and effector T cell balance during hepatitis C virus infection.
Hepatitis C virus (HCV) is remarkable at disrupting human immunity to establish chronic infection. Upregulation of inhibitory signaling pathways (such as T cell Ig and mucin domain protein-3 [Tim-3]) and accumulation of regulatory T cells (Tregs) play pivotal roles in suppressing antiviral effector T cell (Teff) responses that are essential for viral clearance. Although the Tim-3 pathway has be...
متن کاملRegulation of proinflammatory Th17 responses during Trypanosoma cruzi infection by IL-12 family cytokines.
Previously, we reported that the transcription factor T-bet (Tbx21) regulates Th17 responses to Trypanosoma cruzi infection in an IFN-γ-independent manner. In an effort to further understand this regulation, we examined the development and plasticity of Th17 cells during T. cruzi infection. Th17 cells recovered from infected Tbx21(-/-) mice were amenable to the inhibitory effects of T-bet, as e...
متن کاملEnhanced Immune Responses of a Hepatitis C Virus core DNA Vaccine by co-Inoculating Interleukin-12 Expressing Vector in Mice
Background: Hepatitis C (HCV) is a worldwide problem without an effective vaccine with more than 170 million chronically infected people worldwide. DNA vaccines expressing antigenic portions of the virus with adjutants have recently been developed as a novel vaccination technology. Objectives: In the present study, a DNA vaccine expressing HCV core protein was developed with IL12 as a genetic a...
متن کاملDifferential regulation of interleukin-10 (IL-10) and IL-12 by glucocorticoids in vitro.
Antigen-presenting cells are thought to modulate the development of Th1 and Th2 cells by the secretion of interleukin-10 (IL-10) and IL-12. Because glucocorticoids (GC) favor the development of Th2 responses, we determined whether dexamethasone (DEX) and hydrocortisone (HC) have differential effects on lipopolysaccharide-induced IL-10 and IL-12 production in whole-blood cultures. Significant in...
