CD8A and Huntington disease: In order to assess a possible molecular mimicry between these two epitopes, we stimulated PBMCs from 32 B*27:05 carriers responsive to pEBNA3A (both AS patients and HD), 5 B*27:09 subjects and 13 B*07 carriers responsive to pEBNA3A (both patients and controls) with pEBNA3A (20 μg/mL) or pDYNEIN (40 μg/mL) for 14 days and tested the reciprocal CD8+ T cell cross-reactivity.
