Question

Quizplus · Accepted Answer

Helper T cells, particularly the CD4+ T cells, are the primary target of HIV-1. During the final phase of infection, when an individual is said to have AIDS, there is a significant decline in the number of helper T cells in the body. This decline weakens the immune system and makes individuals more susceptible to infections and other complications. B cells, memory B cells, and plasma cells are not typically affected in the same way as helper T cells during HIV-1 infection.
