Mitochondria are crucial in cell life, as they are the main intracellular source of energy, and have a main role in cell death as they contain molecules able to trigger apoptosis. However, mitochondria can also release molecules called ‘damage-associated molecular patterns’ (DAMPs) that trigger a potent innate immune response and cause inflammation through the engagement of the Toll-like receptors (TLR). During human immunodeficiency virus (HIV) infection, a proinflammatory status is present that is not completely explained by the activity of the virus per se, or by the effective immune response against the virus. However, the presence of significant amounts of DAMPs of mitochondrial origin, such as extracellular plasmatic mtDNA, in the peripheral blood of subjects with HIV infection suggests that part of the inflammation typical of such infection could be because of the activity of these molecules, and thus opens new therapeutic perspectives.

Abstract

Mitochondria are crucial in cell life, as they are the main intracellular source of energy, and have a main role in cell death as they contain molecules able to trigger apoptosis. However, mitochondria can also release molecules called ‘damage-associated molecular patterns’ (DAMPs) that trigger a potent innate immune response and cause inflammation through the engagement of the Toll-like receptors (TLR). During human immunodeficiency virus (HIV) infection, a proinflammatory status is present that is not completely explained by the activity of the virus per se, or by the effective immune response against the virus. However, the presence of significant amounts of DAMPs of mitochondrial origin, such as extracellular plasmatic mtDNA, in the peripheral blood of subjects with HIV infection suggests that part of the inflammation typical of such infection could be because of the activity of these molecules, and thus opens new therapeutic perspectives.
