How HIV evades CTL recognition.

Abstract:

:The human immunodeficiency virus (HIV) is unique in its capacity to produce chronic disease in almost all infected hosts. To accomplish this, it has evolved multiple mechanisms to effectively evade the immune response. HIV encodes at least one protein that makes infected cells resistant to CTL killing by downmodulating epitope (peptide plus MHC-I protein) density on the infected cell surface. In addition, HIV encodes several mechanisms to promote apoptosis of HIV-specific CTLs. The end result is that infected cells have a reduced susceptibility to CTLs, survive longer and produce more viral antigenic variants that can further evade the immune response.

  • Potential Role of Regulatory T Cells in Mother-to-Child Transmission of HIV.

    abstract:BACKGROUND:Mother-to-child transmission of HIV-1 occurs in a minority of HIVinfected mother-infant pairs, even without any interventions. The mechanisms that protect the majority of HIV-exposed infants from infection are unclear. T regulatory cells (Treg) have important immunomodulatory functions, but their role in the...
