Spontaneous release of leukocyte migration inhibition factor (LMIF) by lymphocytes in chronic lymphatic leukemia patients. 1984

S M Crivii, and M Crişan, and M Crişan

Leukocyte migration inhibition factor (LMIF) activity expressed as a migration index was studied in sera of 13 chronic lymphatic leukemia (CLL) patients and 14 healthy subjects. LMIF activity was present in 92.8% of CLL patients and 14% of controls. The LMIF activity of lymphocyte culture supernatants in the same patients and 7 controls was also studied. A LMIF-like activity was found both, in the sera and phytohemagglutinin (PHA) unstimulated cell supernatants in 9 of 13 patients (69.2%). These results demonstrate the ability of malignant B cells to release LMIF or LMIF-like factors spontaneously.

D007961 Leukocyte Migration-Inhibitory Factors Protein factor(s) released by sensitized lymphocytes (and possibly other cells) that inhibit the movement of LEUKOCYTES, especially polymorphonuclear cells, away from their site of release. Assays for these factors are used as tests for cellular immunity. Two of the common assays are the LEUKOCYTE MIGRATION CAPILLARY TUBE TECHNIQUE (LMCT) and the LEUKOCYTE MIGRATION AGAROSE TEST (LMAT).
