Recent studis have explored antigen-specific impetides modulation using checkpoint ligands. For instance, coupling PD- L1 to islet- specific peptides (np., insulin B- chain) created a tolerogenic signal that prevented diabetes in NOD mice.

Monitoring for impe- related adverse events is critial. Potential biomarkers included de soluble costimulatory estuulles, T cell repertoire skewing, and changes in autoantibody titers. Close collaboration between endocrinologists, reumatologists, and oncologists will bee essential to manage complications like tyreiditis, hyphyphyphyphytitis, or colitis that may ariste with systemic therapy.
