Assay of human lymphokines in vitro. Evidence for a migration stimulation factor (MStF) which interferes with the macrophage migration inhibition assay. 1976

J G Aaskov, and H M Anthony

When cultured in vitro, human lymphocytes produced a range of materials which were able to reduce the migration inhibitory effect of human macrophage migration inhibition factor (MIF) and in some cases stimulated macrophage migration to greater than control levels. In addition, lymphocytes stimulated with antigen or mitogen produced a lymphokine-like migration stimulation "factor". Detectable production of this factor occurred 24--48 h after antigen stimulation. The migration stimulation factor (MStF) (MW 50-250,000; pI 6-5) was not chemotactic and could be separated from migration inhibition and chemotactic factors by chromatography and iso-electric focussing.

UI	MeSH Term	Description	Entries
D007525	Isoelectric Focusing	Electrophoresis in which a pH gradient is established in a gel medium and proteins migrate until they reach the site (or focus) at which the pH is equal to their isoelectric point.	Electrofocusing,Focusing, Isoelectric
D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008222	Lymphokines	Soluble protein factors generated by activated lymphocytes that affect other cells, primarily those involved in cellular immunity.	Lymphocyte Mediators,Mediators, Lymphocyte
D008263	Macrophage Migration-Inhibitory Factors	Proteins released by sensitized LYMPHOCYTES and possibly other cells that inhibit the migration of MACROPHAGES away from the release site. The structure and chemical properties may vary with the species and type of releasing cell.

D008264	Macrophages	The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D002464	Cell Migration Inhibition	Phenomenon of cell-mediated immunity measured by in vitro inhibition of the migration or phagocytosis of antigen-stimulated LEUKOCYTES or MACROPHAGES. Specific CELL MIGRATION ASSAYS have been developed to estimate levels of migration inhibitory factors, immune reactivity against tumor-associated antigens, and immunosuppressive effects of infectious microorganisms.
