| Research Abstract |
1,Search of HIV-infected Long Term Nonprogressors
We searched the patients who maintained CD4+-T Cell count more than 500 for recent six years among more than 2100 patients who hospitalized to Osaka National hospital and International Medical Center of Japan. As a result, 15 patients were found.
2,Expression of APOBEC3G
We received anti-APOBEC3G antibody and it successfully showed the high expression of intracellular APOBEC3G through the FI assay. However, this expression level in PBMC goes up and down in each lot. Thus, we constructed the standard cell line which expresses the APOBEC3G protein constantly, and this cell line was useful for the normalization of APOBEC3G. Generally, non-Adherent cells were used for the HIV infection assay. However, it is difficult to make and maintain the appropriate APOBEC3G expression constantly. Then, we establish the cell line which is based on the adherent cell line, 293T cells. Among the clone A3G-C1 and A3G-C4, vif-defected HIV could not infect with. APOBEC3G expression in these cells was high and functional. By these cell line, quantification of APOBEC3G is possible and the measurement of APOBEC3G expression among Long Term Nonprogressors and slow progressors.
