2015 Fiscal Year Research-status Report

プロテオミクスに基づく新規の抗肝炎ウイルス戦略

Research Project

Project/Area Number 15K08493
Research InstitutionUniversity of Yamanashi

Principal Investigator

森石 恆司  山梨大学, 総合研究部, 教授 (90260273)

Project Period (FY) 2015-04-01 – 2018-03-31
KeywordsC型肝炎 / B型肝炎 / HCV / HBV / 抗ウイルス化合物
Outline of Annual Research Achievements

1.本年度はPPIスクリーニング系の構築では、core蛋白質と機能的に相互作用するPA28γのホモダイマーによるmammalian-two hybride screening系の構築をした。化合物スクリーニングLOPAC ライブラリーを使い、数個の候補化合物が確認できた。また、HBVcore promoterアッセイ系を構築し、新規抗ウイルス剤として数種類を同定した。
2.新規培養細胞スクリーニング系によって化合物ライブラリをスクリーニングし、感染および病原性を標的にした化合物同定を行った。プロテオミクス解析から、FKBP6とNS5Aとの相互作用がウイルス複製に重要であることを報告し、FKBP6/8の複合体形成を阻害する化合物同定を行った。
3.CDK阻害剤にHBV複製を阻害する化合物を見つけ、その作用機構を次年度解析する。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

ほぼ順調に研究は進展しており、現時点で問題ない。

Strategy for Future Research Activity

研究計画に変更はなく、同定した抗ウイルス化合物について作用機構解析を行い、新規抗肝炎ウイルス療法開発に繋げる。
