h-gly-leu-phe-oh

GLF (H-Gly-Leu-Phe-OH), a tripeptide isolated from α-lactalbumin with immunostimulatory properties, prevents alopecia, epidermal thickening, and adipocyte layer thinning induced by the anticancer agent Etoposide [1].

[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.

Atrial Natriuretic Peptide (ANP) has the sequence of H-Ser-Leu-Arg-Arg-Ser-Ser-Cys-Phe-Gly-Gly-Arg-OH, is a 28 amino acid peptide. ANP is a powerful vasodilator, and a protein (polypeptide) hormone secreted by heart muscle cells. It is involved in the hom
