Heat shock factor 1 promotes neurite outgrowth and suppresses inflammation in the severed spinal cord of geckos

The low intrinsic growth capacity of neurons and an injury-induced inhibitory milieu are major contributors to the failure of sensory and motor functional recovery following spinal cord injury. Heat shock transcription factor 1 (HSF1), a master regulator of the heat shock response, plays neurogeneti...

description The low intrinsic growth capacity of neurons and an injury-induced inhibitory milieu are major contributors to the failure of sensory and motor functional recovery following spinal cord injury. Heat shock transcription factor 1 (HSF1), a master regulator of the heat shock response, plays neurogenetic and neuroprotective roles in the damaged or diseased central nervous system. However, the underlying mechanism has not been fully elucidated. In the present study, we used a gecko model of spontaneous nerve regeneration to investigate the potential roles of gecko HSF1 (gHSF1) in the regulation of neurite outgrowth and inflammatory inhibition of macrophages following spinal cord injury. gHSF1 expression in neurons and microglia at the lesion site increased dramatically immediately after tail amputation. gHSF1 overexpression in gecko primary neurons significantly promoted axonal growth by suppressing the expression of suppressor of cytokine signaling-3, and facilitated neuronal survival via activation of the mitogen-activated extracellular signal-regulated kinase/extracellular regulated protein kinases and phosphatidylinositol 3-kinase/protein kinase B pathways. Furthermore, gHSF1 efficiently inhibited the macrophage-mediated inflammatory response by inactivating IkappaB-alpha/NF-kappaB signaling. Our findings show that HSF1 plays dual roles in promoting axonal regrowth and inhibiting leukocyte inflammation, and provide new avenues of investigation for promoting spinal cord injury repair in mammals.
