Abstract

The loss of T helper cell (TH) function in asymptomatic HIV type 1-infected individuals occurs before the decline in CD4+ T cells. At least part of the loss in TH function results from changes in immunoregulatory cytokine profiles. To investigate the role of IL-10 in such dysregulation, we tested whether: (a) expression of IL-10-specific mRNA would be upregulated in PBMC from asymptomatic, HIV-infected (HIV+) individuals; (b) PBMC from these same individuals would produce increased levels of IL-10 when stimulated in vitro with phytohemagglutinin; and (c) defective antigen-specific TH function could be restored by anti-IL-10 antibody. We observed that IL-10-specific mRNA was marginally upregulated, and increased levels of IL-10 were produced by PBMC from HIV+ individuals compared with PBMC from uninfected individuals. Those individuals whose TH function was more severely compromised produced higher levels of IL-10. Additionally, defective antigen-specific TH function in vitro could be reversed by anti-IL-10 antibody, including the response to HIV envelope synthetic peptides. Furthermore, the antigen-specific TH responses of HIV-uninfected PBMC could be reduced with IL-10, a process reversed by anti-IL-10. These results confirm that the early loss of TH function in HIV+ individuals is due at least in part to cytokine-induced immune dysregulation, and support the hypothesis of a switch from a predominant type 1 state to a predominant type 2 condition in HIV infection.

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.

Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
