Abstract
We evaluated the ability of normal human peripheral blood monocytes and polymorphonuclear leucocytes (PMNL) isolated from patients with acquired immunodeficiency syndrome (AIDS) or AIDS-related conditions (ARC) to migrate toward a chemoattractant. Migration in blind-well chambers was compared to that under agarose. Chemotaxis results obtained from both assays for PMNL were similar, however there was a difference in the results for monocyte Chemotaxis. PMNL isolated from patients with AIDS, but not ARC, exhibited decreased spontaneous and directed chemotaxis when assessed in blind-well chambers and under agarose. Spontaneous and directed Chemotaxis in blind-well chambers of AIDS patients' monocytes was normal. Directed migration of monocytes from ARC patients was greater than that of control, but spontaneous migration was comparable. Under agarose, spontaneous migration was depressed in monocytes of AIDS patients, while migration toward the attractant was depressed in those of ARC patients.Keywords
