ATP-sensitive Potassium Channels and L-type Calcium Channels are Involved in Morphine-induced Hyperalgesia after Nociceptive Sensitization in Mice

Introduction: We investigated the role of ATP-sensitive potassium channels and L-type calcium channels in morphine-induced hyperalgesia after nociceptive sensitization. Methods: We used a hotplate apparatus to assess pain behavior in male NMRI mice. Nociceptive sensitization was induced by three days injection of morphine and five days of drug free. On day 9 of the schedule, pain behavior te...

Potassium channels and regulation of the microcirculation.

Potassium channels represent the dominant ion conductance of vascular smooth muscle cell membranes and play a major role in the regulation of membrane potential (18,19). Membrane potential, in turn, regulates the open state probability of voltage-gated Ca channels (18,19). Thus, as illustrated in Fig. 1, the closure of K channels and the loss of outward K current lead to depolarization, opening...

P13: Potassium Channels and Long-Term Potentiation Formation

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. ...
