只知其一,不知其二,PD-L2究竟为何物? - 知乎
PD-L2又称CD273或B7-DC与PD-L1同属 B7家族蛋白 成员,它是继PD-L1后发现的可以与PD-1结合的第二个重要配体,PD-L2与PD-1结合后会发挥抑制免疫细胞功能的作用。
PDCD1LG2 - Wikipedia
Programmed cell death 1 ligand 2 (also known as PD-L2, B7-DC) is a protein that in humans is encoded by the PDCD1LG2 gene. [5][6] PDCD1LG2 has also been designated as CD273 (cluster of differentiation 273).

PD-L2知多少 - 知乎 - 知乎专栏
最近的一项研究表明,PD-L2特异性T淋巴细胞能够识别肿瘤或免疫细胞表达的靶标,并能够诱导Th1细胞因子的释放,例如IFN-γ和TNF-α。 PD-L2可以在免疫细胞上表达,包括B淋巴细胞(可以与滤泡辅助性T细胞上的PD-1结合,导致长寿命浆细胞数量减少),以及树突状细胞以及其他类型的造血和非造血细胞。 从生理上讲,PD-L2与PD-L1在结肠成肌纤维细胞(MHC-II+细胞群)表达时,发挥了调节粘膜CD4+ T细胞应答的作用。 这些PD-L2+细胞通过抑制IL-2而抑制CD4+ Th …
