MSH: A soluble factor produced by activated T-LYMPHOCYTES that induces the expression of MHC CLASS II GENES and FC RECEPTORS on B-LYMPHOCYTES and causes their proliferation and differentiation. It also acts on T-lymphocytes, MAST CELLS, and several other hematopoietic lineage cells.,CSP: lymphokine produced by antigen or mitogen activated T lymphocytes that enhances the ability of B lymphocytes to present antigen, primes B lymphocytes to proliferate in response to anti-Ig and lipopolysaccharide, and regulates the production of IgG and IgE by B lymphocytes; it also acts as a growth factor for T lymphocytes and as a maturation factor for mast cells.,NCI: One of a group of related proteins made by leukocytes (white blood cells) and other cells in the body. Interleukin-4 is made by a type of T lymphocyte. It causes B lymphocytes to increase and to make antibodies and also increases the production of T lymphocytes. Interleukin-4 made in the laboratory is used as a biological response modifier to boost the immune s
