IL-27 posttranslationally regulates Y-box binding protein-1 to inhibit HIV-1 replication in human CD4+ T cells.

ABSTRACT:

Objectives

IL-27 is known as an antiviral cytokine that inhibits HIV, hepatitis C virus, and other viruses. We have previously demonstrated that, IL-27 posttreatment after HIV-infection inhibits viral replication in primary CD4 T cells.

Design

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).

Methods

IL-27-treated CD4 T cells were infected with HIVNL4.3 or HIV-LUC-V and assessed the anti-HIV effect. HIV infection was monitored by p24 antigen ELISA or luciferase assay. HIV fusion/entry and uncoating were determined by BlaM-Vpr assay and HIV fate of capsid and/or HIV Entry/Uncoating assay ba
