背景信息

KIR2DS2 is associated with reduced post-transplant recurrence and improved prognosis in solid tumors of hematologic malignancies and is an attractive target for NK-based therapeutic strategies. Furthermore, KIR2DS2 is associated with increased activation of anti-glioblastoma cells and improved clinical responses in breast, colorectal, non-small cell lung and hepatocellular carcinomas. (PMID: 35768150) Currently KIR2DS2 has been shown to directly recognize viral deconjugating peptides in the context of HLA-C and is protective against chronic hepatitis C virus infection. The high sequence homology between KIR2DS2 and inhibitory KIRs (KIR2DL2 and KIR2DL3) has made it difficult to develop an antibody that specifically detects KIR2DS2.
