The magnitude of IFN‐γ T‐cell responses to the CD4 peptide pool was lower in PLWH compared to matched HD (p = 0.023, Figure 4B), while no significant difference was observed in responses to the CD8 peptide pool between the PLWH and HD (p = 0.54, Figure 4B). The gene discussed is CD8A; the disease is Huntington disease.
