The effect of granulocyte colony-stimulating factor (GCSF) treatment of polymorphonuclear neutrophils (PMN) in vitro was studied with respect to their candidacidal activity. The candidacidal activity of PMN was found to be significantly increased when they were pretreated with GCSF. Fluconazole (1 microg/ml) was found to be highly fungistatic (90%) for Candida albicans Sh27 and collaborated with PMN for significantly increased killing. Collaborative killing by PMN significantly increased when they were treated with GCSF before and after fungal exposure. The enhancing activities of GCSF required optimization of the GCSF dose and were thus inoculum and strain dependent.
研究了粒细胞集落刺激因子(GCSF)体外处理多形核中性粒细胞(PMN)对其杀念珠菌活性的影响。发现用GCSF预处理PMN后,其杀念珠菌活性显著增加。发现氟康唑(1微克/毫升)对白色念珠菌Sh27具有高度抑菌作用(90%),并与PMN协同作用,显著增强杀菌效果。当PMN在真菌暴露前后用GCSF处理时,其协同杀菌作用显著增强。GCSF的增强活性需要优化GCSF剂量,因此其增强活性取决于接种量和菌株。
