Immune activation and inflammation in HIV‐1 infection: causes and consequences
Abstract
Thorough research on HIV is progressively enabling us to understand the intricate mechanisms that link HIV‐1 infection to the onset of immunodeficiency. The infection and depletion of CD4+ T cells represent the most fundamental events in HIV‐1 infection. However, in recent years, the role played by chronic immune activation and inflammation in HIV pathogenesis has become increasingly apparent: quite paradoxically, immune activation levels are directly associated with HIV‐1 disease progression. In addition, HIV‐1‐infected patients present intriguing similarities with individuals of old age: their immune systems are characterized by a loss of regenerative capacity and an accumulation of ageing T cells. In this review, we discuss the potential reasons for the establishment of sustained immune activation and inflammation from the early stages of HIV‐1 infection, as well as the long‐term consequences of this process on the host immune system and health. A simplified model of HIV pathogenesis is proposed, which links together the three major facets of HIV‐1 infection: the massive depletion of CD4+ T cells, the paradoxical immune activation and the exhaustion of regenerative capacity.

“The anti-CMV response appears to monopolize a significant fraction of the whole T cell repertoire [97], so that it might compromise the response to other antigens by shrinking the remaining T cell repertoire and reducing T cell diversity.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
