Physical exercise influences astrocytes in the striatum of a Parkinson's disease male mouse model.

Physical exercise is considered an adjuvant treatment to Parkinson's disease (PD) patients, possibly reducing inflammatory responses in the brain. Studies have stated that physical exercise protects dopaminergic neurons in PD models produced by neurotoxins. However, few studies focused on immunohistochemically reacted astrocytes and morphometric analyses of these cells in a PD mouse model submitted to physical exercise.

Physical exercise increases the production of tyrosine hydroxylase and CDNF in the spinal cord of a Parkinson's disease mouse model.

Previous research advocates that exercise is a non-pharmacological therapy for Parkinson's disease (PD). However, few studies have investigated the effects of exercise on central nervous system structures other than the nigrostriatal pathway by using PD animal models. This study investigated the effects of exercise on tyrosine hydroxylase (TH)- and cerebral dopamine neurotrophic factor (CDNF)-containing spinal-cord neurons.
