This infectious agent's genome codes for pol and gag, and the TAR hairpin of its genome binds to the tat protein, which interacts with receptors for CXCR4, also known as fusin, which itself is a receptor for SDF-1. This virus uses the Env cap made up of gp41 and gp120 proteins to latch onto CD4 receptors. Infection by this virus is treated with [*] AZT, and Kaposi's sarcoma can be found in patients infected with it. This

Infection by this virus is treated with [*] AZT, and Kaposi's sarcoma can be found in patients infected with it. This virus uses reverse transcriptase to attack leukocytes known either as "helper" or "cytotoxic" T cells, and infection with this lentivirus can cause opportunistic infection and immune system collapse. For 10 points, name this retrovirus that causes AIDS.
