Question

The development of memory B cells in response to an antigen requires the secretion of ________ from ________ cells.

A) interferon-γ : cytotoxic T cells
B) tumor necrosis factor-α : natural killer cells
C) interleukin-6 : helper T cells
D) interleukin-1 : cytotoxic T cells
E) interleukin-2 : helper T cells

Answer 1

The development of memory B cells is facilitated by cytokines secreted from helper T cells, particularly Th2 cells, which promote the differentiation of B cells into antibody-producing plasma cells.

Step-by-step explanation:

The development of memory B cells in response to an antigen requires the secretion of cytokines from helper T cells. Specifically, Th2 cells are a type of helper T cell that secretes cytokines which act on B cells to drive their differentiation into plasma cells that produce antibodies. This process is critical for the adaptive immune response as it helps the body to quickly and more effectively fight off pathogens that it has previously encountered.
