ECF-A and C5a were chemotactic both for eosinophils and neutrophils. However, when eosinophils comprised approximately 10 per cent or more of a mixed leucocyte population, they were preferentially attracted by both of these agents. Marked synergism was observed between ECF-A and C5a in their ability to attract eosinophil leucocytes.
嗜酸性粒细胞趋化因子A(ECF-A)和C5a对嗜酸性粒细胞和中性粒细胞均有趋化作用。然而,当嗜酸性粒细胞在混合白细胞群体中占约10%或更多时,它们会优先被这两种因子吸引。在吸引嗜酸性粒细胞方面,观察到ECF-A和C5a之间在趋化能力上有明显的协同作用。
