Research Papers that Mention the Interaction
“ NMMA also blocked the stimulation of GABA release in prepubertal rats, as well as the inhibition of GABA release induced by leptin in peripubertal rats.”
Nitric oxide synthase inhibition prevents leptin induced Gn-RH release in prepubertal and peripubertal female rats.“Subsequent application of L-NMMA significantly decreased GABA levels (from 0.47+/-0.08 to 0.22+/-0.07 ng/10 microl) but potentiated MAP and HR responses to a muscle contraction.”
“ L-NMMA (0.3 mM) and L-NAME (0.5 mM) increased K(+)-evoked GABA release, indicating that NO plays an inhibitory role in GABA release from PP.”
“Rats were perfused with the artificial CSF containing L-NMMA (0.1, 0.3 and 1.0 mM) or its inactive isomer D-NMMA (1.0 mM) for 1 h. Infusion of L-NMMA , but not its D-isomer, dose-dependently increased GABA concentration.”
“However, NMMA markedly inhibited the release of GABA induced by high potassium, which indicates that NO plays a role in potassium-induced release of GABA.”
“This inhibition in LHRH release induced by GABA was blocked by NMMA (300 microM), which indicates that GABA converts the stimulatory effect of NO on LHRH release into an inhibitory one, presumably via GABA receptors, which activate chloride channels that hyperpolarize the cell.”
“2 Tetrodotoxin, l‐NMMA and l‐NNA, but not d‐NMMA, inhibited the relaxations induced by electrical stimulation, ATP and GABA , but not those in response to NO.”
