[Leu144,Arg147]-PLP (139-151) is a mutant peptide fragment of myelin proteolipid protein (PLP), with the tryptophan and histidine at positions 144 and 147 respectively replaced by leucine and arginine. [Leu144,Arg147]-PLP (139-151) also serves as a T cell receptor (TCR) antagonist for encephalitogenic Th1 clones, blocking their activation in vitro. Furthermore, [Leu144,Arg147]-PLP (139-151) can inhibit the development of experimental autoimmune encephalomyelitis (EAE).

Cys-β- Amyloid (12 - 28)

LCMV gp33-41 (TFA), the carboxyl-extended 11-aa-long peptide, is an lymphocytic choriomeningitis virus sequence restricted by MHC class I H-2Db molecules and presented to cytotoxic T lymphocytes.
