...Zhongying Wang; Huahua Fan; Rufeng Xie; Jie Yang; Yana Ren; Yiming Yang; Wei Li Background/Aims: This study investigated the priming effect of sphingosine 1-phosphate (S1P) on formyl-Met-Leu-Phe-OH (fMLP)-activated neutrophils, by specific analysis of the neutrophil respiratory burst...

..., the major clinical manifestation being a granulomatous cheilitis. The capability of the patient’s phagocytes to undergo a respiratory burst in response to different stimuli was markedly depressed and only 10% of the patient’s neutrophils were able to reduce nitroblue tetrazolium when stimulated with phorbol...

...E. Piva; S. De Toni; A. Caenazzo; M. Pradella; F. Pietrogrande; M. Plebani Neutrophil NADPH oxidase is a membrane-bound enzyme complex responsible for the reduction of oxygen to superoxide anion in the respiratory burst. Impaired neutrophil function has often been reported in myeloproliferative...

... manner. We also examined the effect of b-FGF on the respiratory burst activity in neutrophils. Although b-FGF alone did not induce intracellular oxidative product formation by neutrophils, it enhanced H 2 O 2 production in neutrophils stimulated by N-formyl-methionyl-leucyl-phenylalanine or phorbol...
