HIV virus selectively infects T helper cells, incorporates its own DNA into the T helper's DNA, and ultimately leads to cell lysis or death. This results in a progressive depletion of CD4+ T cells, which are critical for the immune response against infections. The loss of immune function ultimately leads to AIDS.
