The pharmacology of calcium channels involved in glutamatergic synaptic transmission from reticulospinal axons in the lamprey spinal cord was analyzed with specific agonists and antagonists of different high-voltage activated calcium channels. The N-type calcium channel blocker omega-conotoxin GVIA (omega-CgTx) induced a large decrease of the amplitude of reticulospinal-evoked excitatory postsy...
Taylor, James T., Luping Huang, Brian M. Keyser, Hean Zhuang, Craig W. Clarkson, and Ming Li. Role of high-voltage-activated calcium channels in glucose-regulated -cell calcium homeostasis and insulin release. Am J Physiol Endocrinol Metab 289: E900–E908, 2005. First published June 14, 2005; doi:10.1152/ajpendo.00101.2005.—Highvoltage-activated (HVA) calcium channels are known to be the primary...
Several types of calcium channels found in the central nervous system are possible participants in triggering neurotransmitter release. Synaptic transmission between hippocampal CA3 and CA1 neurons was mediated by N-type calcium channels, together with calcium channels whose pharmacology differs from that of L- and P-type channels but resembles that of the Q-type channel encoded by the alpha 1A...
Voltage-gated calcium channels are required for many key functions in the body. In this review, the different subtypes of voltage-gated calcium channels are described and their physiologic roles and pharmacology are outlined. We describe the current uses of drugs interacting with the different calcium channel subtypes and subunits, as well as specific areas in which there is strong potential fo...
Pyrethroids are commonly used insecticides for both household and agricultural applications. It is generally reported that voltage-gated sodium channels are the primary target for toxicity of these chemicals to humans. The phylogenetic and structural relatedness between sodium channels and voltage-gated calcium (Ca) channels prompted us to examine the effects of the type 1 pyrethroid allethrin ...
Long-term potentiation (LTP) is a form of activity-dependent plasticity that occurs during learning. Potassium channels are the most diverse group of all ion channels that related to synaptic plasticity. Small-conductance calcium-activated potassium channels (SKs) are found in hippocampal CA1 neurons and by inhibiting of postsynaptic potentials are involved in synaptic transmission impairment. ...
NSCaTE is a short linear motif of (xWxxx(I or L)xxxx), composed of residues with a high helix-forming propensity within a mostly disordered N-terminus that is conserved in L-type calcium channels from protostome invertebrates to humans. NSCaTE is an optional, lower affinity and calcium-sensitive binding site for calmodulin (CaM) which competes for CaM binding with a more ancient, C-terminal IQ ...
the purpose of this study was to investigate the effects of 8 weeks of endurance training (et) on ? -1a protein of pre-synaptic p-q-type calcium channels in fhl and soleus muscles of rats. 16 male wistar rats provided from razi institute, were randomly divided to 2 groups (control-sham; n=8 and endurance training; n= 8). training group performed 8 weeks (5 session/week) of endurance training on...
