_______ are Antigen-Presenting Cells

Question

_______ are antigen-presenting cells.
A) Plasma cells
B) Memory T cells
C) Macrophages
D) Mast cells

Accepted Answer

Macrophages are antigen-presenting cells, which means they are able to present antigens to other immune cells in order to activate an immune response. Plasma cells are responsible for producing and secreting antibodies, memory T cells are a type of immune cell that can recognize and respond to previously encountered pathogens, and mast cells are involved in allergic reactions and inflammation, but they are not antigen-presenting cells.
