متن کاملNeurotransmitter Transporters
Neurotransmitters are released into the extracellular space during synaptic transmission. The actions of these chemical signals are terminated through active uptake by transporters that are located in the plasma membrane of neurons and glial cells. Transporters harness electrochemical gradients to force the movement of transmitter back into cells against its concentration gradient. These protei...
متن کاملLocal Anesthetics Properties of Local Anesthetics
The first clinical uses of a local anesthetic agent occurred in 1884, when cocaine was employed as a topical agent for eye surgery and to produce a nerve block. These events inaugurated a new era, that of regional anesthesia. New applications were developed, including spinal, epidural, and caudal anesthesia. The search for a better local anesthetic led to chemical synthesis of a number of other...
متن کاملPorters and neurotransmitter transporters.
Uptake of neurotransmitters involves multiple transporters acting in different brain locations under different physiological conditions. The vesicular transporters are driven by a proton-motive force generated by a V-ATPase and their substrates are taken up via proton/substrate exchange. The plasma membrane transporters are driven by an electrochemical gradient of sodium generated by a Na+/K(+)...
متن کاملListening to Neurotransmitter Transporters
However, the conducting properties of transporters go well beyond this simple picture (Sonders and Amara, Division of Biology California Institute of Technology 1996). For example, the 5-HT transporter is not electro-genic; yet it displays at least four distinct conducting Pasadena, California 91125 states (Mager et al., 1994). Three of these states are permeable to Na ϩ ions, and the other to ...
