B7-H3 is one of the most recently identified members of the B7/CD28 superfamily of costimulatory molecules serving as an accessory modulator of T-cell response. Recently, B7-H3 expression has been reported in several human cancers indicating an additional function of B7-H3 as a regulator of antitumor immunity. However, its precise physiologic role is still elusive, because both stimulatory and inhibitory capacities have been demonstrated. This paper summarizes the available data on B7-H3 in the regulation of T-cell response focusing on its potential role in antitumor immunity.
B7-H3是共刺激分子B7/CD28超家族中最近发现的成员之一,作为T细胞反应的辅助调节因子。最近,有报道称B7-H3在几种人类癌症中表达,这表明B7-H3作为抗肿瘤免疫调节因子具有额外的功能。然而,其确切的生理作用仍然难以捉摸,因为已经证明它具有刺激和抑制能力。本文总结了关于B7-H3在调节T细胞反应方面的现有数据,重点关注其在抗肿瘤免疫中的潜在作用。
