MR1 (MHC class I-related molecule 1) is a highly conserved antigen-presenting molecule that binds microbial vitamin B2 (riboflavin) precursor derivatives, enabling recognition by mucosal-associated invariant T (MAIT) cells. Discovered in the 1990s, MR1 differs from classical MHC-I molecules as it is non-polymorphic and presents metabolites rather than peptide antigens. Its interaction with MAIT cells, a subset of innate-like T cells abundant in mucosal tissues, plays a critical role in bridging innate and adaptive immunity against bacterial and fungal infections.
MR1-specific antibodies have emerged as valuable tools to study MR1's biology and therapeutic potential. Early antibodies like 26.5 and 8F2.F9 facilitated the identification of MR1's expression on antigen-presenting cells and its role in MAIT cell activation. More recently, antibodies such as clone 12.2 have been used to block MR1-antigen presentation, elucidating its involvement in infections, cancer, and autoimmune diseases. In oncology, anti-MR1 antibodies are explored for their ability to modulate MAIT cell responses, as MR1 is often overexpressed on tumor cells. Conversely, agonist antibodies may enhance antimicrobial immunity by boosting MAIT cell activity. Current research also investigates MR1-targeting bispecific antibodies for precision immunotherapy. Despite progress, challenges remain in understanding MR1's ligand diversity and tissue-specific regulation, driving ongoing development of advanced antibody-based reagents.
