摘 要:T-cells critically contribute to protection against Mycobacterium tuberculosis infection,and impaired T-cell responses can lead to disease ***-inflammatory and immunosuppressive cytokines affect T-cells,and fine-tuned regulation of cytokine signaling via the Jak/STAT signaling pathways is crucial for appropriate T-cell *** STAT3 phosphorylation as a consequence of aberrant cytokine signaling has been described to occur in pathognomonic T-cell responses in inflammatory and autoimmune *** characterized blood samples from tuberculosis patients(n=28)and healthy contacts(n=28)from Ghana for ***-specific T-cell responses,constitutive cytokine production,and SOCS3 and pSTAT3 *** modulation of primary CD4+T-cells was performed to determine the effects of SOCS3 on T-cell functions.T-cells from tuberculosis patients expressed higher levels of IL-10 and IL-6 and lower levels of T helper type(TH)17 cytokines after ***-specific stimulation compared to healthy *** addition,tuberculosis patients had higher IL-10 and IL-6 levels in the supernatants of non-stimulated immune cells and plasma samples compared to healthy ***,aberrant cytokine expression was accompanied by high constitutive pSTAT3 levels and SOCS3 expression in *** analysis identified an IL-6/IL-10 co-expression-based principal component in tuberculosis patients that correlated with high pSTAT3 ***3 contributed to a regulatory component,and tuberculosis patients with high SOCS3 expression showed decreased TH1 cytokine expression and impaired IL-2-induced STAT5 ***3 over-expression in primary CD4+T-cells confirmed the SOCS3 inhibitory function on IL-2-induced STAT5 *** conclude that constitutive pSTAT3 and high SOCS3 expression are influential factors that indicate impaired T-cell functions in tuberculosis patients.
