h-arg-lys-oh

H-Arg-Lys-OH is a dipeptide composed of L-arginyl and L-lysine residues.

H-Arg-Lys-OH TFA, a dipeptide consisting of L-arginyl and L-lysine residues, is referenced in [1].

H-PRO-HIS-CYS-LYS-ARG-MET-OH acetate acts as antioxidant by reacting with active oxygen species such as superoxide and hydroxyl radicals.

[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. Immunizing mice with this peptide (50 µg) mixed in complete Freund's adjuvant (CFA) elevates IL-4 levels in the spleen. While it suppresses Th1 cell activation in vitro, it does not do so in vivo; instead, it promotes the development of regulatory T cells. Preimmunization with [Leu144, Arg147]-PLP (139-151) postpones the onset of experimental autoimmune encephalomyelitis (EAE) triggered by encephalitogenic peptides from PLP (178-191), myelin oligodendrocyte glycoprotein (MOG) (92-106), or myelin basic protein (MBP) in mice.
