新月体的形成是肾功能急剧恶化的典型病理改变。T细胞参与了新月体的形成和新月体肾炎的病理进展。T细胞亚群中CD4n +和CD8n +细胞，以及T细胞共刺激因子以不同的方式介导免疫应答，参与了新月体的发生、发展和纤维化，亦或者延缓其恶化。该文综述T细胞在新月体形成和发展的作用机制，以期为临床治疗新月体肾炎提供新靶点。n “,”The formation of crescent is a typical pathological change characterized by a rapid deterioration of renal function.T lymphocytes are involved in the formation of crescent and the pathological progression of crescent nephritis.CD4n + and CD8n + cells in T lymphocyte subsets, and T cell costimulatory factors mediate immune responses in different ways.They participate in the occurrence, development and fibrosis of crescent, or delay their deterioration.In order to provide a new target for clinical treatment of crescent nephritis, we review the mechanism of T lymphocytes in the formation and development of crescentic body.n
