“Objective We investigated whether the … oxide (NO) precursor, l-arginine , can prevent the antidepressant-like … of the fast-acting antidepressant, ketamine , in a genetic rat model of depression, and/or induce changes in the glutamate (Glu)/N-methyl-d-aspartate receptor (NMDAR)/NO/cyclic guanosine monophosphate (cGMP) signalling pathway.”
“Results l-Arginine pre-treatment prevented the antidepressant-like effect of ketamine in the FST, as well as a ketamine-induced increase in cGMP levels in the frontal cortex and hippocampus of FSL rats.”
