WebT cells carry fragments of pathogens into the lymph nodes, where a B cell evolution factory is created. B cells that bind to the T cells (actually the antigen the T cells are carrying), even a little bit, are stimulated to divide with "somatic hypermutation" so you get a lot of varying copies. The ones that best match the T cells are stimulated ... WebHow are T cells linked to HIV and AIDS? HIV enters its genetic information into helper T cells to make copies of itself. When this happens, the helper T cells die. This severely...
