migration

any cyclical movements (usually annual) that occur during the life history of an animal at definite intervals, and always including a return trip from where they began. The exact derivation of the word is from the Latin ‘migrate’ meaning to go from one place to another, but biologically a return journey is part of the accepted definition of the term, the outward journey being termed EMIGRATION and the inward journey IMMIGRATION.

migration inhibition test
an in vitro test for detection of cell-mediated immunity (or delayed hypersensitivity) in which peritoneal exudate cells (lymphocytes and macrophages) are packed in capillary tubes and placed in a medium; if the medium contains an antigen to which the lymphocytes are primed, macrophage migration from the tubes is inhibited by lymphokines, particularly macrophage inhibiting factor, released by the antigen stimulated lymphocytes.
