S-HIV-1 OLIGOPEPTIDE-5 SP.

This oligopeptide functions as an analog of human AIMP1, initiating cellular communication by interacting with specific cell surface receptors. It actively stimulates the growth of human dermal fibroblasts and enhances collagen synthesis, which leads to a notable improvement in skin firmness, smoothness, and elasticity. Furthermore, it promotes the production of Keratinocyte Growth Factor (KGF), accelerating skin cell renewal and the shedding of pigmented keratinocytes, thereby contributing to a brighter and more even skin tone. As a member of the Fibroblast Growth Factor (FGF) superfamily, it specifically engages FGFR-2b receptors on epithelial cell membranes, triggering phosphorylation of C-terminal tyrosine residues. This initiates signaling cascades that drive epithelial cell growth, proliferation, and differentiation, ultimately bolstering skin vitality and resilience, while also modulating extracellular matrix dynamics.
