Cytokine-induced release of histamine from basophil leukocytes from AIDS patients.
Cytokine-induced histamine release from basophil leukocytes was examined in cell suspension from AIDS patients and compared with healthy controls. Cells from approximately half of the AIDS patients, in contrast to none from the control group, showed histamine release after stimulation with interleukin-4 (IL-4), tumor necrosis factor alpha (TNF alpha), lymphotoxin (LT) and interferon gamma (IFN gamma). These cytokines seem to induce histamine release from cells from AIDS patients by interaction with the cell surface immunoglobulins, since removal of the immunoglobulins prior to the exposure of the cytokines completely abolished the response to the cytokines. IL-1 alpha, IL-1 beta, IL-3, colony stimulating factor (CSF) and granulocyte-macrophage-CSF (GM-CSF) caused significant histamine release from cells from a similar number of AIDS patients and controls.
