Abstract: Provided is recombinant protein for ulcerative colitis treatment or prevention that is recombinant protein based on milk fat globule-EGF factor 8 (MFG-E8) protein, consisting of an amino acid sequence of SEQ ID NO: 1 or SEQ ID NO: 3, to be administered to a target for treatment or prevention, thereby expecting treatment or prevention of ulcerative colitis. Further, provided is a composition for ulcerative colitis treatment or prevention containing recombinant protein based on milk fat globule-EGF factor 8 (MFG-E8) protein, consisting of an amino acid sequence of SEQ ID NO: 1 or SEQ ID NO: 3, as an active ingredient.

Abstract: The present invention provides a polypeptide for preventing or treating idiopathic pulmonary fibrosis, which is synthesized by linking 9 to 10 amino acids together and comprises an amino acid sequence consisting of arginine (R, Arg)-glycine (G, Gly)-aspartic acid (D, Asp)-valine (V, Val)-phenylalanine (F, Phe)-proline (P, Pro)-serine (S, Ser)-tyrosine (Y, Tyr)-threonine (T, Thr). Accordingly, the polypeptide for preventing or treating idiopathic pulmonary fibrosis according to the present invention may restore lung function to normal by fundamentally treating lung tissue that has undergone fibrosis due to idiopathic pulmonary fibrosis, and furthermore, may delay or prevent the onset of idiopathic pulmonary fibrosis.
