Outline of Final Research Achievements |
We analyzed the association of HLA with clinical outcome in 536 HIV-1 subtype A/E-infected treatment-naive Vietnamese and found that HLA-C*12:02 and HLA-A*29:01-B*07:05-C*15:05 were protective allele and detrimental haplotype, respectively. We further analyzed the sequences of HIV-1 in these individuals and identified 303 HLA-associated mutations which are candidates of CTL escape mutations. We analyzed ART treatment patients and found 90% success rate of treatment for 42 months. Out of 26 patients with treatment failure, 5 patients were infected with HIV-1 having drug resistance mutations in protease. We also found a significant association of TPVr treatment with hyperlipidemia in the treatment patients.

Academic Significance and Societal Importance of the Research Achievements |
本研究により、HIV-1サブタイプA/E慢性感染者で、エイズ進行に関与するHLAを同定できた。また、初めてHIV-1サブタイプA/Eに対する免疫逃避変異を明らかにでき、HIV-1増殖抑制能を有したCTLを明らかにできたことは、今後のHIV-1サブタイプA/Eに対するワクチン開発に貢献できる。治療患者の解析では、ベトナムでも日本と同じレベルの治療効果が得られたが、プロテアーゼ阻害剤に対する薬剤耐性変異が確認され、今後このような薬剤耐性ウイルスが広まることが危惧された。
