Electrophysiology of ascending, possibly cholinergic neurons in the rat laterodorsal tegmental nucleus: comparison with monoamine neurons.

abstract：:Intracellular recordings were used to examine the mechanisms underlying the 5-hydroxytryptamine (5-HT)4 receptor-mediated depolarization seen in CA1 region pyramidal cells in in vitro hippocampal brain slices. This depolarization was mimicked and occluded by administration of the membrane permeable cyclic adenosine mo...

abstract：:Considerable evidence suggests that low (picomolar) concentrations of the HIV-1 envelope glycoprotein gp120 induce neuronal cell death by stimulating the release of microglial toxins, which in turn activate N-methyl-D-aspartate (NMDA) receptors. Conversely, high (micromolar) concentrations of gp120 have been reported ...
