Abstract 2778: Discovery and preclinical characterization of BAY 1905254 a novel immune checkpoint inhibitor for cancer immunotherapy targeting the immunoglobulin-like domain containing receptor 2 (ILDR2)

ILDR2 is a type I transmembrane protein belonging to the B7 family of immunomodulatory receptors with 98 % sequence identity between the extracellular domains of human and murine orthologues. The exact physiological role of ILDR2 is still unclear, but it has been implicated in the development of type 2 diabetes and the formation of tri-cellular junctions. Our detailed analyses reveal that ILDR2 is expressed in kidney, testis, liver, and lymph...
