Notably, combined treatment with resveratrol and curcumin resulted in a greater reduction in α-synuclein levels compared with the MPTP group ( P < 0.001) and showed numerically lower levels than either compound administered alone; however, inter-treatment comparisons among L-DOPA + carbidopa, resveratrol, curcumin, and resveratrol + curcumin did not reach statistical significance ( P > 0.05) Biochemical parameter assessed by TNF-α levels Analysis of TNF-α levels revealed marked neuroinflammatory alterations across the experimental groups, as shown in Table 4 .
