Brief Report: Impaired CD4 T-Cell Response to Autophagy in Treated HIV-1-Infected Individuals

J Acquir Immune Defic Syndr. 2017 Feb 1;74(2):201-205. doi: 10.1097/QAI.0000000000001201.

Abstract

Autophagy restricts infection of CD4 T lymphocytes by HIV-1, but little is known about autophagy in treated HIV-1-infected individuals. We have analyzed the capability of CD4 T cells from aviremic-treated individuals to trigger autophagy and correlated this response with parameters known to be important for immunological recovery. Autophagy was significantly decreased in CD4 T cells from HIV-1-treated individuals compared with uninfected controls, and this defective autophagic response was more pronounced in individuals with poor CD4 T-cell recovery, suggesting a link between impaired autophagy in CD4 T cells and chronic immunological defects that remain in treated HIV infection.
