Statistical analysis of the data obtained from triplicates of three independent experiments is summarized in Table 5 and indicates that differential usage of CCR5, CXCR4, or CCR8 by HIV-1 and HIV-2 is not correlated (data not shown but always p > 0.05) with productive infection of Mø, imDCs, mDCs, and TCD4+. Here, CCR8 is linked to infection.
