In this manuscript, no significant differences were depicted in the relative percentages of CD8+ Tregs and CD8+ Teffs among LT, ND T1D patients versus healthy normal controls in basal conditions as opposite to the results we published on CD4+ Tregs and CD4+ Treg/Teff ratio within PBMC that were found higher in the LT disease patients than in normal controls in basal conditions. The gene discussed is CD8A; the disease is type 1 diabetes mellitus.
