人中性粒细胞对侵入体内的细菌具有吞噬作用,与免疫系统共同构成机体防御体系。当机体受到细菌的感染时,人中性粒细胞受由感染源引起的各种趋化性因子的浓度变化引导,向细菌感染部位或病灶移动与存在于感染部位的多种可溶性刺激物接触后激活还原型烟酰胺腺嘌呤二核苷酸磷酸(NAD
Human neutrophils have phagocytosis of bacteria that invade the body and together with the immune system constitute the body’s defense system. When the body is infected with bacteria, human neutrophils are guided by changes in the concentration of various chemotactic factors caused by the source of infection, and contact with bacterial infection sites or lesions after exposure to multiple soluble stimuli present at the site of infection. Activation of Reduced Nicotinamide Adenine Dinucleotide Phosphate (NAD)
