Effects of glutamic acid, kainic acid and aspartic acid on GABA release from rat retina degenerated by kainic acid. 1984

Y Kamada, and A Mizuno, and H Miyazaki, and H Tsuneoka, and M Matsuda

The effects of L-glutamic acid (Glu), kainic acid (KA) and L-aspartic acid (Asp) on 14C-GABA release from the rat retina degenerated by KA were investigated. In the normal rat retina, Glu initially enhanced GABA release and subsequently inhibited it. Both KA and Asp did not have dual effects; KA enhanced GABA release, while Asp inhibited it. In the KA-degenerated retina, the stimulatory effect of Glu or KA on GABA release was markedly suppressed, while the inhibitory effects of Glu or Asp were preserved.

UI MeSH Term Description Entries
D007608 Kainic Acid (2S-(2 alpha,3 beta,4 beta))-2-Carboxy-4-(1-methylethenyl)-3-pyrrolidineacetic acid. Ascaricide obtained from the red alga Digenea simplex. It is a potent excitatory amino acid agonist at some types of excitatory amino acid receptors and has been used to discriminate among receptor types. Like many excitatory amino acid agonists it can cause neurotoxicity and has been used experimentally for that purpose. Digenic Acid,Kainate,Acid, Digenic,Acid, Kainic

D012160 Retina The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent. Ora Serrata
D012162 Retinal Degeneration A retrogressive pathological change in the retina, focal or generalized, caused by genetic defects, inflammation, trauma, vascular disease, or aging. Degeneration affecting predominantly the macula lutea of the retina is MACULAR DEGENERATION.
