ABSTRACT
<p><b>OBJECTIVE</b>To measure CCR5 and CXCR4 chemokine receptor expression on CD4 and CD8 T cells in HIV-1 infection and to relate levels to the distribution of CD45RO memory and CD45RA-naive subsets after effective HAART.</p><p><b>METHODS</b>Four-color cytofluorometry with appropriate conjugated monoclonal antibodies (mAbs) was performed to define CD45RA and CD45RO subsets of CD4 and CD8 T cells and measure the expression of CCR5, CXCR4 in blood from 43 received HAART patients and 5 non-treated HIV and 13 healthy controls.</p><p><b>RESULTS</b>The levels of CCR5 and CXCR4 on CD4 and CD8 T cells and their CD45RO/CD45RA subsets in HIV-1-infected patients had not any statistical significance than that on control subjects and effective HAART could adjust the expression on T cells.</p><p><b>CONCLUSION</b>CXCR4/CCR5 plays an important role in the progress of HIV-1 infection. The most favorable condition for treatment should be initiated before stage B.</p>
