| Outline of Final Research Achievements |
Aim of this study was to investigate the functional involvement of HLA-linked IkBL gene (NFKBIL1) in the regulation of susceptibility to infectious disease and immune-related diseases, especially focusing on HIV infection. By analyzing polymorphisms in IkBL promoter region, it was found that susceptibility to HIV infection as associated with low expression allele of IkBL. By using T cell line and epithelial cell line overexpressing IkBL, it was suggested that IkBL inhibited replication of HIV. In addition, it was observed that spicing of many genes was regulated by IkBL. Furthermore, a novel HIV infection-related gene, of which splicing was regulated by IkBL, was identified to be involved in the regulation of HIV infection.
