WebThese residual cognitive impairments may involve aberrant deposition of amyloid β-peptides (Aβ). By unknown mechanisms, Aβ accumulates in the lysosomal and autophagic compartments of neurons in the HIV-infected brain. Here we identify the molecular events evoked by the HIV coat protein gp120 that facilitate the intraneuronal accumulation of Aβ.

WebPrevious studies have shown that in aged HIV patients, there is increased amyloid deposition and plaque formation (Daily et al. 2006; Green et al. 2005; Rempel and Pulliam 2005). However, it was unclear what is the earliest site for Aβ accumulation in patients with HIV and how this might be related to the alterations in protein handling during ... WebFragments of prostatic acid phosphatase (PAP248-286) in human semen dramatically increase HIV infection efficiency by increasing virus adhesion to target cells.
