Unlike B lymphocytes, T lymphocytes do not generate a secreted form of their antigen receptor after they are activated and proliferate. This is because the effector functions of T cells are restricted to:
A) Responses important in protozoan infections, but not other types of infections
B) Interactions with large helminthic parasites, which cannot be phagocytosed
C) Interactions with other cells, such as virus-infected cells or other immune cells
D) Responses important in mucosal surfaces (e.g., the lung), where antibodies cannot go
E) Stimulating B cells and not any other types of cells

T cells interact with other cells, such as virus-infected cells or other immune cells, through direct cell-to-cell contact mediated by their T cell receptor (TCR) and other surface molecules. They do not secrete antibodies like B cells do, but instead, they can secrete cytokines that can activate other immune cells and coordinate immune responses.
