Figure 2. Model of HIV-1 infection in HPCs.
Multipotent HPCs can become infected with HIV-1, leading either to active infection, cell death, and virion release, or to latent infection. Latently infected HPCs with self-renewal capacity will then continue to self-renew, generating an expanded reservoir of latent HIV-1 in these cells. If the host cell is stimulated to differentiate, the latent virus reactivates, leading to cell death and virion release.
