Vacuolar H(+)-ATPase (V-ATPase) plays a key role in neurotransmission. It provides the energy for the uptake and storage of neurotransmitters in synaptic vesicles and granules. It also may play a role in the biogenesis of synaptic vesicles ...
Tyrosine hydroxylase regulation in neurotransmission and neuroplasticity [0.03%]

The modulation of neurotransmitter synthesis is a fundamental mechanism influencing neurotransmission and neuronal plasticity during development. The regulation of the tyrosine hydroxylase (TH) has been used to elucidate specific adaptative...
Physiology and biochemistry of peptidergic cotransmission in Aplysia [0.03%]

The marine mollusc Aplysia, whose simple nervous system facilitates study of the neural basis of behavior, was used to investigate the role of peptidergic cotransmission in feeding behavior. Several novel modulatory neuropeptides were purif...
Scinderin and chromaffin cell actin network dynamics during neurotransmitter release [0.03%]

It has been demonstrated that filamentous actin (F-A) is mainly localized in the cortical surface of the chromaffin cell. This F-A network acts as a barrier to the chromaffin granules impeding their contact with the plasma membrane. Stimula...
Calcium-dependent modulation of the facilitation of transmitter release at neuromuscular junctions of Drosophila [0.03%]

The relationship between external Ca and twin pulse facilitation of transmitter release has been investigated in neuromuscular junctions of Drosophila larvae using external electrodes to record excitatory junctional currents (ejcs). The deg...

In 1952 Fatt and Katz recorded at a frog neuromuscular junction while stimulating the nerve and found "... that successive endplate potential responses varied in a step-like manner, corresponding to units of miniature endplate potentials" (...
Role of different types of Ca2+ channels and a reticulum-like Ca2+ pump in neurotransmitter release [0.03%]
不同种类的Ca2+通道和类似内质网的Ca2+泵在神经递质释放中的作用

The mechanism of transmitter release by intracellular Ca has been explored by recording presynaptic Ca concentration ([Ca2+]i) with Ca-sensitive fluorescent dyes and by controlling [Ca2+]i with photosensitive Ca chelators. [Ca2+]i decays sl...

The hypothesis that the improvement of neurochemical changes involving the brain dopaminergic and cholinergic systems in aged rats may be related to the their capacity of coping with stress has been investigated by testing the effect of var...
