肥大细胞(MC)在几种急性细菌感染模型中参与协调宿主的早期先天免疫和适应性免疫应答。大多数这种活性导致细菌的早期清除和感染的及时解决。然而,在慢性感染期间,由于MC-细菌相互作用的长期性质,MC在决定感染命运中的作用明显更加复杂。根据病原体的性质、感染的严重程度及其与先前存在的炎性疾病的相关性,MC可能促进而不是抑制慢性感染并加重其病理后果。
Mast cells (MCs) have been implicated in orchestrating the host's early innate immune and adaptive immune responses in several models of acute bacterial infections. Most of this activity results in early clearance of the bacteria and timely resolution of infection. However, during chronic infections because of the prolonged nature of MC-bacterial interactions, the role of the MC in determining the fate of infection is markedly more complex. Depending on the nature of the pathogen, severity of infection and its association with a preexisting inflammatory disease, MCs may promote rather than contain chronic infections and exacerbate their pathological sequellae.
