Significant association was found between IL-27rs40837 polymorphisms with susceptibility to HIV infection (AG vs AA: adjusted OR = 1.60, 95% CI, 1.11-2.30, P = 0.012; AG+GG vs AA: adjusted OR = 1.44, 95% CI, 1.02-2.03, P = 0.038) and disease progression (LTNP: AG vs AA: adjusted OR = 2.33, 95% CI, 1.13-4.80, P = 0.021; TP: AG vs AA: adjusted OR = 1.50, 95% CI, 1.04-2.24, P = 0.030).
Here, we evaluated the anti-HIV effect of IL-27 pretreatment in CD4 T cells from healthy donors prior to HIV infection with HIVNL4.3 or vesicular stomatitis virus G glycoprotein (VSV-G)-pseudotyped HIV-luciferase virus (HIV-LUC-V).
IL-27 signaling (IL-27 and its receptor) may be involved in the pathogenesis of HIV infection and immune reconstitution in HIV/AIDS patients who underwent HAART.
Herein, we show that in vitro HIV infection, as well as intracellular HIV-Tat (Tat) and Tat peptides, inhibit LPS-induced IL-27 production in human MDMs, suggesting impairment of the TLR4 signaling pathway.
