HIV-1 counteracts an innate restriction by amyloid precursor protein resulting in neurodegeneration

Abstract

HIV infection results in elevated beta-amyloid (Aβ) levels in the brain, but the underlying mechanisms are unclear. Here, the authors show that amyloid precursor protein inhibits virion production and that HIV Gag, counteracting this antiviral function, results in secretase-dependent Aβ production and neuron degeneration.
