| migration inhibition test | A test which measures the presence of migration-inhibitory factor. Usually peritoneal macrophages are placed in a capillary tube in the presence or absence of supernatants from activated T-cells. If MIF is present, the migration of monocyte/macrophages is reduced. Synonym: macrophage migration inhibition test, migration inhibition test. (05 Mar 2000) |

| migration theory | An obsolete theory that sympathetic ophthalmia is caused by a migration of the pathogenic agent through the lymph channels of the optic nerve. (05 Mar 2000) |
| migration-inhibitory factor | <growth factor> A soluble, nondialysable factor that is produced by sensitised lymphocytes following exposure to a specific antigen. It inhibits macrophage migration and causes adherence. It was originally defined on the basis of inhibition of emigration of mononuclear cells from capillary (haematocrit) tubes, more recently a 13 kD protein with migration inhibitory activity has been isolated. Acronym: MIF Synonym: inhibition factor. (22 Sep 2002) |
