Although cholecystokinin octapeptide-8 is important for neurological function, its neuroprotective properties remain unclear. We speculated that cholecystokinin octapeptide-8 can protect human retinal pigment epithelial cells against oxidative injury. In this study, retinal pigment epithelial cells were treated with peroxynitrite to induce oxidative stress. Peroxynitrite triggered apoptosis in these cells, and ...

Traumatic spinal cord injury (SCI) activates the hypothalamic-pituitary-adrenal (HPA) axis, a potent neuroendocrine regulator of stress and inflammation. SCI also elicits a profound and sustained intraspinal and systemic inflammatory response. Together, stress hormones and inflammatory mediators will affect the growth and survival of neural and non-neural cells and ultimately neurologic ...
