Outline of Final Research Achievements |
In this study, we developed a method to predict the binding affinity of human leukocyte antigen (HLA) and peptide fragments. While the previous methods use experimental affinity databases of the peptides, our methods can predict the binding affinity only using the structural information of HLA. Therefore, it is an important feature of our method that prediction is possible even for HLA alleles with few experimental data. In addition, the relative binding affinity of “AAAAAIFVI”, which is considered as a candidate for an antigenic peptide of Behcet's disease (BD), was high for HLA-B*51 (this HLA is correlated with BD), and was low for HLA-B*52 (this HLA is not correlated with BD). These results indicate the possibility that AAAAAIFVI is an antigenic peptide of BD.

Academic Significance and Societal Importance of the Research Achievements |
本研究で開発したHLAとペプチド断片の結合親和性の予測法は、特定のHLAに結合するペプチドの網羅的探索に利用可能であり、他のHLA関連疾患への応用も期待される。例えば、リウマチや糖尿病といった生活習慣病、様々な自己免疫疾患、癌などもHLAと有意な相関を示すことが知られている。さらに、ウイルス感染における免疫応答の個人差や、抗原提示を利用したペプチドワクチンの開発などにおいても、HLAとペプチドの親和性が重要な意味を担っている。今後、結合親和性の予測精度を向上させることができれば、これらを含む様々な医学・薬学研究に貢献することが期待される。
