CA2 — ITIH4

Text-mined interactions from Literome

Medina et al., Eur J Neurosci 1999 (Ion Channel Gating) : We report that in rat hippocampal neuronal cultures, GP120 induces a dramatic and persistent increase in [Ca2+ ] i which is prevented by drugs that either deplete ( caffeine, carbachol, thapsigargin ) or block ( dantrolene ) Ca2+ release from intracellular stores ... Our results show that the GP120 induced rise in [Ca2+ ] i originates from intracellular calcium stores, and suggest that intracellular stores of calcium may play a determinant role in the pathological actions of GP120
Holden et al., Neuroscience 1999 : Role of Na+/H+ exchangers, excitatory amino acid receptors and voltage operated Ca2+ channels in human immunodeficiency virus type 1 gp120 mediated increases in intracellular Ca2+ in human neurons and astrocytes ... The N-methyl-D-aspartate receptor antagonists ( +/- ) -2-amino-5-phosphonopentanoic acid ( AP5 ), memantine and dizocilpine significantly ( P < 0.01 ) lowered gp120 induced increases in [ Ca2+ ] i in neurons ... Drugs that block gp120 induced changes in [Ca2+ ] i in neurons and astrocytes may help in the treatment of HIV-1 dementia
Belmadani et al., Neuroscience 2001 (AIDS Dementia Complex...) : Consistent with abrogation of excitotoxic pathways, fura-2 imaging showed selective deficits in gp120 dependent intracellular Ca2+ responses in ethanol pretreated slices
Minami et al., Neuropharmacology 2003 (Pain) : Gp120 evoked allodynia in a dose dependent manner with the maximum effect at 1 pg/mouse, and stimulated a rapid increase in intracellular free Ca2+ concentration ([Ca2+]i) in the dorsal horn cells of the spinal cord ... The kappa-opioid agonist U-50,488 significantly enhanced the gp120 stimulated increase in [ Ca2+ ] i in spinal slices prepared from EP3 ( -/- ) mice, and the simultaneous addition of U-50,488 with gp120 reproduced the gp120 induced allodynia in EP3 ( -/- ) mice
Lo et al., Brain Res 1992 : Three patterns of [Ca2+ ] i increases were observed : in one pattern the [Ca2+ ] i rose rapidly and transiently as a single peak, in a second pattern gp120 induced [Ca2+ ] i oscillations that subsided when the protein was removed, and in a third pattern the oscillations continued long after washout of gp120
Lipton et al., Neuron 1991 : Moreover, complete protection from gp120 induced [Ca2+ ] i increases and neurotoxicity is afforded by incubation with glutamate-pyruvate transaminase, which breaks down endogenous glutamate as verified by HPLC
Nath et al., Brain Res 1995 : The peak levels of gp120 induced increases in [Ca2+ ] i were not affected by calcium channel blockers lanthanum and nicardipine, by glutamate receptor antagonists MK-801 and NBQX, or by removal of endogenous glutamate with glutamate dehydrogenase
