Preferential migration of revertant CD8⁺T cells. (A) Electropherograms showing homozygous peaks in CD4⁺CD8⁻ARPC1B⁻ and CD4⁻CD8⁺ARPC1B⁻ and heterozygous peak in CD4⁻CD8⁺ARPC1B⁺ in sorted subpopulations in PHA T-cell lines of P1 as compared with bulk population in a HC. The site of second mutation is indicated in red. (B) Ratio of migrated ARPC1B⁺CD8⁺ (red) and ARPC1B⁻CD8⁺ (blue) T cells at to SDF1-α as compared with HC (n = 6, shaded area). Mean ± SEM. Input: percentage of T cells expressing ARPC1B before migration.
