CD8A and hematocrit: As IL-6 was the only inflammatory marker that was found to be significantly modulated during HT (Figure 6A), we looked for correlations between IL-6 levels and the percentages of naive and TEMRA CD8+ T-cell subsets in the HT group at the 6-month time point to determine if the modulations in these subsets could be related to changes in IL-6 levels during HT.
