Furthermore, the CD4+ T-cell count recovery speed of RI, LI non-AIDS and LI AIDS patients were 16, 11 and 11 cells/mm3 per month, respectively (Supplementary Figure S5A) whereas the corresponding CD4/CD8 ratio recovery speed was 0.042, 0.028 and 0.018 per month, respectively (Supplementary Figure S5B). This evidence concerns the gene CD4 and AIDS.
