COMPOSITION COMPRISING BRANCHED MULTIPEPTIDE VACCINE AND VACCINE COMPRISING THE SAME

摘要

Provided are a branched multi-peptide composition and a vaccine including the same. The branched multi-peptide vaccine according to the present invention is easy to be produced and utilized, thereby being easily applied to the treatment, and is capable of maintaining stable reaction in vivo, such that it is expected that the branched multi-peptide vaccine according to the present invention acts as an effective vaccine. Further, for the tumor antigen peptide, the present invention may select an antigen that is largely expressed in a malignant brain tumor. In addition, from now on, it is expected that tumor antigens having a large expression level may be analyzed depending on tumor characteristics of an individual patient, such that the branched multi-peptide vaccine according to the present invention may be utilized for producing personalized branched peptides and vaccines using the same.
