What cells secrete lymphokines?

Lymphokines are a subset of cytokines that are produced by a type of immune cell known as a lymphocyte. They are protein mediators typically produced by T cells to direct the immune system response by signaling between its cells.

What is secreted by lymphocytes?

Helper lymphocytes secrete this enzyme in response to (1) soluble antigen which has been processed by cells bearing the appropriate MHC antigens; (2) immobilized antibodies against the T cell receptor complex; (3) a combination of phorbol ester and calcium ionophore.

What does lymphokine mean?

: any of various substances (as an interleukin) of low molecular weight that are not antibodies, are secreted by T cells in response to stimulation by antigens, and have a role (as the activation of macrophages or the enhancement or inhibition of antibody production) in cell-mediated immunity.

What is secreted by T cells?

Once stimulated by the appropriate antigen, helper T cells secrete chemical messengers called cytokines, which stimulate the differentiation of B cells into plasma cells (antibody-producing cells). Regulatory T cells act to control immune reactions, hence their name.
