Regulation of neuronal chloride homeostasis by neuromodulators

Regulation of neuronal chloride homeostasis by neuromodulators

KCC2 is the central regulator of neuronal Cl(-) homeostasis, and is critical for enabling strong hyperpolarizing synaptic inhibition in the mature brain. KCC2 hypofunction results in decreased inhibition and increased network hyperexcitability that underlies numerous disease states including epilepsy, neuropathic pain and neuropsychiatric disorders. The current holy grail of KCC2 biology is to ...

Differential Regulation of Neocortical Synapses by Neuromodulators and Activity

Synapses are continually regulated by chemical modulators and by their own activity. We tested the specificity of regulation in two excitatory pathways of the neocortex: thalamocortical (TC) synapses, which mediate specific inputs, and intracortical (IC) synapses, which mediate the recombination of cortical information. Frequency-sensitive depression was much stronger in TC synapses than in IC ...

Opposite regulation of Slick and Slack K+ channels by neuromodulators.

Slick (Slo2.1) and Slack (Slo2.2) are two novel members of the mammalian Slo potassium channel gene family that may contribute to the resting potentials of cells and control their basal level of excitability. Slo2 channels have sensors that couple channel activity to the intracellular concentrations of Na+ and Cl- ions (Yuan et al., 2003). We now report that activity of both Slo2 channels is co...
