T Cells of the Immune System Include

Question

T cells of the immune system include
A) CD4, CD8, and plasma cells.
B) cytotoxic and helper cells.
C) plasma, antigen-presenting, and memory cells.
D) lymphocytes, macrophages, and dendritic cells.
E) class I MHC, class II MHC, and memory cells.

Accepted Answer

T cells include cytotoxic and helper cells. CD4 T cells are helper cells, while CD8 T cells are cytotoxic cells. Plasma cells are a type of B cell, and antigen-presenting and memory cells are not exclusive to T cells. Lymphocytes, macrophages, and dendritic cells are different types of immune cells that include T cells, B cells, and other cells. Class I and class II MHC are both involved in antigen presentation, but memory cells are not exclusive to T cells.
