Oxygen sensing with ion channels
pAper type 290 Channels Volume 8 Issue 4 AutoCommentAry A decrease in arterial O 2 pressure (pO 2) elicits a peripheral chemosensory reflex that increases ventilation and sympathetic nerve activity. This reflex is initiated at the carotid body glomus (Type 1) cells where the reduced pO 2 alters the activities of various ion channels and causes cell depolarization. The depolarization opens the v...
متن کاملRegulation of oxygen sensing by ion channels.
O(2) sensing is of critical importance for cell survival and adaptation of living organisms to changing environments or physiological conditions. O(2)-sensitive ion channels are major effectors of the cellular responses to hypoxia. These channels are preferentially found in excitable neurosecretory cells (glomus cells of the carotid body, cells in the neuroepithelial bodies of the lung, and neo...
متن کاملAcid-Sensing Ion Channels
Acetylcholine is a neurotransmitter synthesized from choline and acetyl coenzyme A. It is localized in large reticular formation neurons, and is the chemical mediator in the synapse of a motor endplate. The electrical signal of the motor nerve terminal causes release of many packets of acetylcholine. The packets are released into the synaptic cleft, where receptors in the postjunctional membran...
متن کاملSensing Magnetic Fields with Magnetosensitive Ion Channels
[-15]Magnetic nanoparticles are met across many biological species ranging from magnetosensitive bacteria, fishes, bees, bats, rats, birds, to humans. They can be both of biogenetic origin and due to environmental contamination, being either in paramagnetic or ferromagnetic state. The energy of such naturally occurring single-domain magnetic nanoparticles can reach up to 10-20 room k B T in the...
