Enhancement of human basophil histamine release by interleukin 5
Substantial evidence indicates a close relationship between eosinophils and basophils. We examined whether interleukin 5 (IL-5), known to be eosinophilopoietic and capable of selectively regulating eosinophil functions, has an affect on basophil functions. IL-5 enhanced basophil histamine release evoked by anti-IgE, formyl-methionyl-leucyl-phenylalanine, or ionophore A23187 at picomolar concent...
متن کاملStaphylococcus aureus peptidoglycan induces histamine release from basophil human leukocytes in vitro.
Whole killed cells, cell walls, and peptidoglycans of Staphylococcus aureus were found to release histamine from human leukocytes and isolated rat mast cells in vitro. The histamine-releasing capability increased in the order of whole bacteria, cell walls, and peptidoglycans. Peptidoglycan was found to release histamine by a nonimmunological mechanism, as demonstrated by release in cells depriv...
متن کاملSuppression of Basophil Histamine Release and Other IgE-dependent Responses in Childhood Schistosoma mansoni/hookworm Coinfection
BACKGROUND The poor correlation between allergen-specific immunoglobulin E (asIgE) and clinical signs of allergy in helminth infected populations suggests that helminth infections could protect against allergy by uncoupling asIgE from its effector mechanisms. We investigated this hypothesis in Ugandan schoolchildren coinfected with Schistosoma mansoni and hookworm. METHODS Skin prick test (SP...
متن کاملDefective inhibition of sodium on basophil histamine release in patients with allergic rhinitis and bronchial asthma.
The aim of this study was to evaluate whether Na+ exerts its inhibitory effect on basophil histamine release induced by immunoglobulin E (IgE)-dependent (anti-IgE) and IgE-independent (N-formyl-methionyl-leucyl-phenylalanine (FMLP), interleukin-3 (IL-3)) stimuli in patients with allergic rhinitis (n = 24) and allergic bronchial asthma (n = 10). Peripheral blood leucocytes were stimulated with a...
متن کاملActivation of basophil and mast cell histamine release by eosinophil granule major basic protein
Major basic protein (MBP) is a primary constituent of eosinophil granules. In this report, we demonstrate that MBP from human eosinophil granules initiates a nonlytic histamine release from human leukocytes. A direct effect of MBP on basophils was confirmed using purified human basophils. The kinetics of release were similar to those reported for poly-L-arginine, although MBP was less potent th...
