The majority of cancers, including colorectal cancer (CRC) with intact DNA mismatch repair, experience a suppressed immune response and resistance to immune checkpoint inhibitors. The MHC class III lymphocyte antigen 6G (LY6G) encodes glycosylphosphatidylinositol (GPI) proteins anchored to the membrane. LY6G proteins and snake venom neurotoxins contain a three-finger (3F) folding domain. Studies suggest that LY6 proteins, such as LY6G6D, may serve as effective tumor-associated antigens that can inhibit anti-tumor immunity in cancers with proficient mismatch repair. Therefore, they are referred to as MHC class III LY6G endogenous immunotoxins. In light of the discovery of LY6G6D as a tumor-associated antigen, T-cell engagers (TcEs) have been developed to simultaneously bind LY6G6D on cancer cells and CD3 on T cells, offering improved treatment options for individuals with metastatic solid tumors resistant to ICIs. This article presents a comprehensive understanding of how modifications in MHC class III genes influence antitumor immunity, and how this knowledge can be translated into effective therapies for patients who do not respond to standard immunotherapy.

Colorectal cancer (CRC) is a prevalent cancer affecting individuals globally and requires more advanced treatment approaches. Through examination of tumor genetic and molecular data, the researchers aimed to identify potential antigens unique to CRC cells and their potential for targeted cytotoxic T-cell therapy. Through this study, LY6G6D was identified as a promising tumor-specific antigen, primarily present in the microsatellite stable (MSS) subtype. A specialized anti LY6G6D/CD3 T cell engager (TcE) was developed and showed significant efficacy in killing CRC cells and activating T cells.
