Helper T cells:

Quizplus · Accepted Answer

Helper T cells are activated by antigens presented with MHC II proteins on the surface of antigen-presenting cells. They do not secrete antibodies themselves, but instead stimulate B cells to produce antibodies. They also do not secrete perforin, which is instead released by cytotoxic T cells to induce apoptosis in infected cells. Helper T cells do not convert into plasma cells, which are a type of B cell that secretes large amounts of antibodies. Therefore, the correct answer is A.
