CSF3 and Parkinson disease: Recent study shows that post-symptomatic treatment with granulocyte colony-stimulating factor (G-CSF) in 1-methyl-4-phenyl-1,2,3, 6-tetrahydropyridine (MPTP) mouse model of PD rats can promote the regeneration of dopaminergic neurons in the SNpc and restore nigrostriatal function [51].
