1 Platelet-activating factor induces histamine release from human skin mast cells in vivo, which is reduced by local nerve blockade. Histamine PCNA clamp associated factor Homo sapiens
2 The purpose of this study was to investigate the extent and possible mechanisms of PAF-induced histamine release in human skin in vivo with the use of dermal microdialysis. Histamine PCNA clamp associated factor Homo sapiens
3 RESULTS: PAF, but not lyso-PAF, caused statistically significant dose-related histamine release and wheal and flare reactions. Histamine PCNA clamp associated factor Homo sapiens
4 CONCLUSIONS: These data suggest that PAF induced histamine release from mast cells in intact human skin indirectly via neurogenic activation. Histamine PCNA clamp associated factor Homo sapiens
5 Further, on the intradermal injection of PAF histamine release and the skin responses, the wheal and the flare, are differentially regulated by neurogenic components. Histamine PCNA clamp associated factor Homo sapiens
