1. Vδ1 decrease of telomere length from Naïve to EM ( Figure 3H ), 2. ( Figure 3B ), 3. CD45RO+CD25− from elderly vs CD45RA+CD28+ from young ( Figure 3 ), 4. Young vs 80 years old ( Figure 3B ), 5. Third group: 80–94 years (n = 19) CD4: 6.2 ± 1.9; CD8: 5.1 ± 1.9 ( Table 1 ). The figures and tables correspond to the original article cited. NS, no changes or no significant changes between the groups; NM, not measured; NC, not compared between the groups.
