LAG3 binding peptides

This disclosure provides peptides that bind to LAG3 and can be used to block its interaction with other molecules such as MHC-II, FGL1, and α-synuclein. These peptides, with their demonstrated activity and short half-life, can be used to activate cellular immunity while significantly reducing the potential for adverse events that is often associated with the antibody-based checkpoint inhibitors. The peptides can be used as stand-alone therapeutics or can be used as immune modulators in combination with other therapies.
