Question

Match the cell type to its function.

Secrete interleukin-2 to facilitate B cell proliferation into memory B cells in addition to effector cells.

A) macrophages
B) helper T cells
C) mast cells
D) B cells
E) natural killer cells
F) cytotoxic T cells
G) plasma cells

Answer 1

Helper T cells are responsible for secreting interleukin-2, which aids in B cell proliferation and differentiation into memory B cells and effector cells such as plasma cells.

Step-by-step explanation:

The cell type that secretes interleukin-2 to facilitate B cell proliferation into memory B cells and effector cells is the helper T cell (Option B). These cells are critical in the immune response, performing a variety of functions, including the activation of B cells. Upon encountering an antigen, helper T cells release cytokines, such as interleukin-2, which stimulate the multiplication of B cells. These B cells can mature into plasma cells that produce antibodies targeting specific pathogens. The helper T cells also assist in activating cytotoxic T cells and enhancing the pathogen-killing functions of macrophages and natural killer cells.
