Abstract

Role of cytochrome c (Cyt c) is an apoptogenic agent under certain conditions. The mitochondrial permeability transition pore (MPTP) plays an important role in cell death since it opens, leading to mitochondrial swelling and release of Cyt c, which initiates apoptosis. By inhibiting the opening of MPTP, cyclosporine A (CSA) may contribute to maintaining mitochondrial homeostasis. We investigate the effects of the partial sciatic nerve injury (PSNI)-induced neuropathic pain model on mitochondrial Cyt c release and the effects of CSA on neuroprotection by mitochondrial stabilizing activity in PSNI rats. Rats were assigned to two groups that received different operations (Group P; PSNI operation, Group S; sham operation). The changes of cyt c and GABAergic neuron were evaluated in the spinal cord tissue. After which, PSNI rats randomly received CSA (Group C) or saline (Group S), and the changes of mechanical thresholds with Cyt c and GABAergic neuron were checked. PSNI in rats increased the release of cytosolic Cyt c. However, GABAergic cells were not decreased in the spinal cord level on the ipsilateral side to the PSNI. The second experiment reveal a reduction in Cyt c release, using CSA in PSNI model. Rats receiving CSA were af...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
