Principal component analysis highlights elite controllers with an immune profile similar to HIV-1 negative individuals: CD8_1, CD8⁺CD38⁺HLA-DR⁺; CD8_2, CD8⁺HLA-DR⁺; CD8_3, CD8⁺CD38⁺; CD4_1, CD4⁺CD38⁺HLA-DR⁺. Brown directed vectors represent the contribution of each variable for the formation of the two-principal components. Colored ellipses represent the 68% of the normal concentration for each group.
