There were no remarkable differences in either CD3+ T cell count (1224 ± 118.2/μL vs 1203 ± 155.5/μL; P ═ 0.529, Figure 2A), CD4+ T cell count (572.9 ± 104.2/μL vs 578.0 ± 135.2/μL; P ═ 0.863, Figure 2B), nor CD8+ T cell count (630.0 ± 159.3/μL vs 636.9 ± 155.8/μL; P ═ 0.852, Figure 2C) between controls and PBC patients. The gene discussed is CD4; the disease is primary biliary cholangitis.
