WebThe CD8+ cell noncytotoxic anti-HIV response (CNAR) A subset of CD8+ cells can suppress HIV replication in infected CD4+ cells without killing the infected cells. HIV replication can be blocked at low CD8+ cell/CD4+ cell ratios ( < 0.05:1). This CNAR is somewhat stronger with cell activation and involves production of a CD8+ cell antiviral ... WebThe high mutation rate of HIV has allowed the virus to escape CD8+ T-cell recognition in addition to its ability to down-regulate surface MHC-I expression from infected cells. Also, by altering the pattern of cytokine production and engagement of cellular receptors, HIV disrupts proper CD8+ T-cell signaling.
