Abstract
The present invention relates to a peptide for preventing or treating inflammatory diseases and a use thereof. According to the novel dimeric or trimeric peptide according to the present invention, it is possible to not only exhibit an excellent therapeutic effect through anti-inflammatory action but also have a very small-sized peptide, thereby minimizing side effects due to the administration of external substances. Therefore, it is expected that the peptide can be used as an active substance that can replace existing therapeutic agents for inflammatory diseases.
