TL;DR: The data indicate that the immunoregulatory PD-1/PD-L1 pathway is operative during a persistent viral infection in humans, and define a reversible defect in HIV-specific T-cell function.
Journal ArticleDOI
CD107a as a functional marker for the identification of natural killer cell activity
TL;DR: It is suggested that employing CD107a as a marker of NK cell functional activity may allow for the identification of a large fraction of activated NK cells that may degranulate in the absence of cytokine secretion.
Journal ArticleDOI

TL;DR: Differences in binding to viral peptide antigens by HLA may be the major factors underlying genetic differences between HIV controllers and progressors, and genome-wide association results implicate the nature of the HLA–viral peptide interaction as the major factor modulating durable control of HIV infection.
Journal ArticleDOI
Immune control of HIV-1 after early treatment of acute infection
Eric S. Rosenberg,Marcus Altfeld,Samuel H. Poon,Mary N. Phillips,Barbara M. Wilkes,Robert L. Eldridge,Gregory K. Robbins,Richard T. D'Aquila,Philip J. R. Goulder,Bruce D. Walker +9 more
TL;DR: It is shown that, despite rebound in viraemia, all subjects were able to achieve at least a transient steady state off therapy with viral load below 5,000 RNA copies per ml, suggesting that functional immune responses can be augmented in a chronic viral infection.
Journal ArticleDOI

TL;DR: Data show that the process of accumulation of escape mutations within HIV is not inevitable, and complex epitope- and residue-specific selection forces, including CTL-mediated positive selection pressure and virus-mediated purifying selection, operate in tandem to shape HIV evolution at the population level.
