Correlation of CD300a expression on B cells with HIV plasma viremia and CD4+ T-cell counts in HIV-infected patients. (A) The correlation between HIV plasma viremia and CD300a expression on the mature (CD19+CD10−) circulating B-cell subsets from the HIV (combined aviremic and viremic) patients. (B) The correlation between CD4+ T-cell counts and CD300a expression on the mature (CD19+CD10−) circulating B-cell subsets from the HIV-aviremic and HIV-viremic patients.
