Furkat [3]

The human immunodeficiency virus (HIV) that causes the disease known as aids selectively infects helper T cells (CD4+).

When CD4+ T cell numbers decrease below a critical level (due to the killing of this cells with different mechanisms), cell-mediated immunity is lost. As a result, the body becomes progressively more susceptible to infections, leading to the development of AIDS.
