Analysis of neurotransmitter anabolic pathway and fatty acids in different subtypes of PD rats. a, e The biological function of neurotransmitter and dopamine in different subtype of PD rats. b–d 5-HT, GABA and DA concentration in SN. f The biological function of lipid and fatty in Mix, TD, and PIGD subtypes of PD rats. Data described are Mean ± SEM, n = 3-6. *p < 0.05, **p < 0.01 and ***p < 0.001 vs. control, #p < 0.05 vs. other subtype
