The invention discloses a shell nacre-derived anti-inflammatory active
peptide and application thereof in preparation of a
skin repair product. The inhibition rate of the active
peptide GEIRYEYF provided by the invention on the
NO release amount is concentration-dependent, and the
NO release amount is reduced by 54.32 + / -2.13% under the concentration of 200 mu g / mL; in addition,
secretion of RAW264.7 macrophage pro-inflammatory cytokines TNF-alpha and IL-6 can be remarkably reduced,
secretion of anti-inflammatory cytokines IL-10 can be improved,
dose dependence is achieved, under the highest concentration, the influence on IL-6
secretion is 47.76 + / -1.02%, the influence on TNF-alpha secretion is 42.01 + / -4.64%, the influence on IL-10 secretion is 41.71 + / -1.67%, and good anti-inflammatory activity is achieved. In addition, the
bioactive peptide has a remarkable proliferation effect on L929 cells, and it is indicated that the
bioactive peptide has the potential of promoting
skin wound healing.
