Investigation of the Role L-Arginine and L-NAME in Dorsal Hippocampus on Anxiety, Depression Brain Level BDNF after Stress Male Mice

Microglia activation in the spinal cord play a major role pathogenesis of neuropathic pain. The p38 mitogen-activated protein kinase (MAPK) regulates microglia activation. Previously, 2′,3′-dideoxycytidine (ddC), nucleoside reverse transcriptase inhibitor (NRTI), was found to induce mechanical allodynia and cords male female mice. In this study, we investigated MAPK signaling development using ...
