CD99蛋白背景综述

CD99 antigen, also known as T-cell surface glycoprotein E2, E2 antigen, Protein MIC2 and CD99, is a single-pass type I  membrane protein which belongs to the CD99 family. CD99 is characteristically expressed in Ewing's sarcoma/primitive neuroectodermal tumor. CD99 down-regulation may have a role in osteosarcoma development and progression. CD99-forced expression in two osteosarcoma cell lines significantly reduced resistance to anoikis, inhibited growth in anchorage independence as well as cell migration, and led to abrogation of tumorigenic and metastatic ability. CD99 acts as a potent suppressor of malignancy in osteosarcoma. CD99 is involved in T-cell adhesion processes. It is involved in spontaneous rosette formation with erythrocytes. Expression of CD99 on the surface of circulating polymorphonuclear cells (PMN) is low compared with expression of CD99 on monocytes or expression of PECAM on PMN. PECAM (CD31) and CD99 regulate distinct, sequential steps in the transendothelial migration of neutrophils during inflammation. CD99 signal transduction can also deliver effective costimulatory signals to T cells.
