Clinical Trial Summary

The authors hypothesize that there is a correlation between the percentage of CD4+ T cells expressing CD32a and/or X and the quantity of DNA found in peripheral blood mononuclear cells in patients infected with HIV-1. Also, that there is a correlation between expression of CD32a and/or X and proviral load.
