斑马鱼已成为研究白细胞募集和炎症的强大模型系统。在此,我们对斑马鱼幼鱼中炎症巨噬细胞的形态和功能进行了表征。通过对L - 丝束蛋白进行免疫标记且无髓过氧化物酶(MPO)共表达以及其细长的形态,可以将这些巨噬细胞与中性粒细胞区分开来。对转基因zMPO:GFP幼鱼的实时成像显示,GFP低表达的巨噬细胞通过伸出细长的伪足迁移至伤口处,并对组织碎片进行吞噬作用,而且对白细胞标志物的流式细胞术分析表明,这些巨噬细胞表达集落刺激因子1受体(CSF1R)。这些发现确定了斑马鱼幼鱼中炎症巨噬细胞独特的功能和形态特征。
Zebrafish have emerged as a powerful model system to study leukocyte recruitment and inflammation. Here we characterize the morphology and function of inflammatory macrophages in zebrafish larvae. These macrophages can be distinguished from neutrophils by immunolabeling of L-Plastin without MPO co-expression and by an elongated morphology. Live imaging of transgenic zMPO:GFP larvae demonstrate that GFPlo macrophages migrate to wounds by extension of thin pseudopods and carry out phagocytosis of tissue debris, and FACS analysis of leukocyte markers indicates expression of CSF1R in these macrophages. These findings identify distinct functional and morphological characteristics of inflammatory macrophages in zebrafish larvae.
