Due to those effects and the ability of G-CSF to cross the intact blood brain barrier (Schneider et al., 2005b), facilitating peripheral administration, G-CSF got in the focus for treating acute and chronic neurodegenerative disorders, with protective and recovery enhancing effects in animal models of stroke, amyotrophic lateral sclerosis (ALS), Alzheimer's disease, Parkinson's disease, traumatic brain injury, and SCI (Diederich et al., 2012). This evidence concerns the gene CSF3 and amyotrophic lateral sclerosis.
