TH and Parkinson disease: In a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinson’s disease mouse model, treatment with Lf-ASX-LPs resulted in 5.0-, 3.1-, and 5.6-fold increases in dopamine levels, TH+ fiber density, and TH+ neurons, respectively, restoring dopaminergic neuron damage.
