When quantified, the relative intensity of CX3CL1-stained endothelial cells was significantly higher in MMD-LB (996.05 ± 358.01), PD (1350.62 ± 355.70), and PSP (1485.01 ± 389.63) as compared with age-matched control (300.74 ± 221.02) groups (p < 0.0001; Figure 3E). The gene discussed is CX3CL1; the disease is Parkinson disease.
