Peptides associated with central nervous system diseases Phamaceutical composition comprising the same as an active ingredient for prevention or treatment of central nervous system diseases

摘要

The present invention relates to peptides having inhibition activity of IL-2 consisting of amino acid sequences represented by sequence No. 1. According to the present invention, the peptides can permeate a brain-blood vessel barrier and a spinal cord-blood vessel barrier of a central nervous system, which did not pass through, with high efficiency. Also, the peptides can perform local administration compared to existing medicines, thereby having fewer side effects. The peptides can perform local administration with high concentration, thereby enabling novel latent treatment and prescription.
