I mean, everyone knows that AIDS patients don't die of the HIV infection, rather the opportunistic infections. But if HIV only affects T lymphocytes, and destroys them, then that means only cell mediated immunity and humoral immunities are affected (since B cells need helper T cells to be activated).
The body should still be producing other types of leukocytes like neutrophils and macrophages, which should eliminate most bacteria. So does HIV infection render the mononucleaf phagocytic system useless as well? If yes, how so?
