They permanently bond to neurotransmitters in the brain, interfering with their ability to function and causing irreversible damage.

a neurotransmitter involved in regulating mood and mental states, has been linked to numerous neurological and mental illnesses, including depression.
since they can be generated from individual patients suffering from illnesses involving the neurotransmitter. hese patient-specific serotonin neurons will be very useful to the discovery of new drugs for diseases ranging from depression
A team from Linköping University and Karolinska Institutet in Sweden have developed a device that delivers the neurotransmitter?
and an electronic control unit releases the neurotransmitter to completely block the pain signals from reaching the brain.

two neurotransmitters that are essential to the body (see schema on page 2). The presence of these receptors on the surface of these stem cells indicated that they had the ability to respond to the presence of dopamine and serotonin in the event of a lesion.
The researchers naturally wondered what cells might be the source of these neurotransmitters a warning signal.
Once released, these neurotransmitters then recruit the stem cells to repair the tooth by binding to their receptors (see schema on page 2). The research team was able to confirm this result by observing that dental repair was absent in rats with modified platelets that do not produce serotonin or dopamine,
In these different organisms, under-expression of the enzyme induced hypersensitivity to oxidative stress (i e. to the toxicity of free radicals), a smaller number of synapses and abnormal neurotransmission due to a reduction in the number of vesicles carrying neurotransmitters.

which brain cells release neurotransmitters to communicate with each other. The scientists blocked glycolysis, another way that cells make ATP,
From this exploration, the scientists revealed that bringing the vesicles back up into the cell after they have released their neurotransmitters is the most energy-demanding process.
which neurotransmitters are shipped--with and without mitochondria. Remarkably, there was no difference in energy levels between the two,
Neurotransmitters--chemicals used by brain cells to communicate--are essential for brain function. In particular, acetylcholine, which was the first neurotransmitter to be discovered,
is involved in cognition and motor functions. Although much is known about the synthesis and secretion of this critical neurotransmitter, the spatial and temporal regulation of acetylcholine synthesis remains unclear.
Specifically, how key metabolic enzymes such as ATP citrate lyase (ACL) and choline acetyltransferase (Chat) find their way to the right region of the neuron is largely unknown.
