New missions for an old agent: granulocyte-colony stimulating factor in the treatment of stroke patients

Abstract

Granulocyte-colony stimulating factor (G-CSF) has a multimodal neuroprotective profile and the cumulative preclinical data from numerous translational studies statistically confirmed the efficacy of G-CSF as a treatment option in ischemic stroke. G-CSF activates anti-apoptotic, anti-oxidative, and anti-inflammatory signaling pathways and stimulates angiogenesis and neurogenesis. In this review, we summarize the role of G-CSF and the corresponding signal transduction pathways regulated by G-CSF in neuroprotection and discuss its potential as a new drug for stroke treatment.
