Where this comes from

Abstract

HHLA2 is a newly identified B7 family member that modulates T-cell functions through interaction with TMIGD2 and possibly a second receptor, with coinhibition in two studies and costimulation in one study. HHLA2 is expressed on a variety of human cancers, and its coinhibitory function makes it a candidate for cancer immunotherapy.
