[Leu144,Arg147]-PLP (139-151) is a mutated fragment of the myelin proteolipid protein (PLP), featuring substitutions of tryptophan to leucine and histidine to arginine at positions 144 and 147, respectively.

PLP (178-191), an immunodominant encephalitogenic epitope from the proteolipid protein (PLP) fragment spanning amino acids 178 to 191, plays a pivotal role in SJL mice. It initiates disease onset earlier compared to the other major encephalitogenic epitope, PLP (139-151), though both epitopes result in similar incidence, severity, and histologic characteristics.
