Since human immunodeficiency virus type 1 ( HIV-1 ) replication is known to be favored under oxidative stress conditions, ex vivo experiments using uninfected PBMCs , primary monocytes or a latently infected promonocytic U1 cell line show that HIV-1 replication and reactivation, monitored by p24 antigen measurement , are inhibited by PAO in a time- and concentration-dependent manner .
 protein: p24 antigen; cell type: primary monocytes; cell type: PBMCs; cell line: promonocytic U1 cell line
