原始语种摘要: BACKGROUND: Neurosteroids have various physiological and neuropsychopharmacological effects. In addition to the genomic effects of steroids, some neurosteroids modulate several neurotransmitter receptors and channels, such as N-methyl-D-aspartate receptors, gamma-aminobutyric acid type A (GABA(A)) receptors, and sigma(1) receptors, and voltage-gated Ca(2+) and K(+) channels. However, the molecular mechanisms underlying the various effects of neurosteroids have not yet been sufficiently clarified. In the nervous system, inwardly rectifying K(+) (Kir) channels also play important roles in the control of resting membrane potential, cellular excitability and K(+) homeostasis. Among constitutively active Kir2 channels in a major Kir subfamily, Kir2.3 channels are expressed predominantly in the...
