CD8A and Huntington disease: After transplant, T cells infiltrating the BM (BM-T cells) of patients in CR displayed an inverted CD4/CD8 ratio compared with HD (p < 0.0001), consistent with a more rapid CD8+ T-cell reconstitution, whereas relapsing patients displayed a wider variability in CD4/CD8 ratio both in BM (Supplementary Fig. 2a) and PB (Supplementary Fig. 2b).
