Pharmaceutical composition for preventing or treating ocular surface disease
A pharmaceutical composition for preventing or treating an ocular surface disease is disclosed, wherein the pharmaceutical composition includes, as an active component, collagen type II α1 based peptide SEQ ID NO: 2 isolated from chondrocyte-derived extracellular matrix (CDEM). In an alkaline burn animal mode treated with peptide SEQ ID NO: 2, the occurrence of corneal opacification is reduced as well as the expression of angiogenic factors. In addition, the expression of inflammatory markers is reduced while the expression of inflammation-inducing factor is suppressed. The peptide SEQ ID NO: 2 may be applied to a pharmaceutical composition for preventing or treating an ocular surface disease.
1. A method of treating an ocular surface disease in a subject in need thereof, comprising;
providing a pharmaceutical composition comprising, as an active component, a peptide comprising the sequence of SEQ ID NO: 2; and
administering the pharmaceutical composition to the subject having a chemical burn to an eye, wherein the ocular surface disease is treated,
wherein the ocular surface disease is selected from the group consisting of corneal opacification, corneal angiogenesis, corneal inflammation, and corneal fibrosis.
2. The method of claim 1 , wherein an amount of the peptide in the pharmaceutical composition is in a range of about 0.1 to about 50 parts by weight based on a total of 100 parts by weight of the pharmaceutical composition.
3. The method of claim 1 , wherein a formulation of the pharmaceutical composition is selected from the group consisting of eye drops, injections, granules, tablets, pills, capsules, gels, syrups, suspensions, emulsions, drips, and liquids.
