Macrophage colony stimulating factor (M-CSF) is a cytokine that regulates the survival, proliferation and maturation of microglial cells. Administration of M-CSF can promote neuronal survival in various models of central nervous system (CNS) injury. Here, in an attempt to induce a neuroprotective microglial cell phenotype and enhance motor neuron survival, mutant SOD1G37R transgenic mice were treated, weekly, with M-CSF starting at onset of disease. Unexpectedly, M-CSF accelerated disease progression in SOD1G37R mouse model of ALS. The shortened survival of M-CSF-treated animals was associated with diminished muscle innervation and enhanced adoption of a macrophage-like phenotype by microglial cells characterised by the upregulation of pro-inflammatory cytokines TNF-α and IL-1β and of the phagocytic marker CD68.
