Neuronal Signaling: Gated Ion Channels

This feed focuses mechanisms underlying addiction and addictive behaviour including heroin and opium dependence, alcohol intoxication, gambling, and tobacco addiction.

The midbrain dopamine system is widely studied for its involvement in emotional and motivational behavior. Some of these neurons receive information from the amygdala and project throughout the cortex. When the circuit and transmission of dopamine is disrupted symptoms may present. Here is the latest research on the amygdala and midbrain dopamine.

Antipsychotic-induced weight gain (aiwg) is a common adverse effect of this treatment, particularly with second-generation antipsychotics, and it is a major health problem around the world. Here are the latest discoveries pertaining to AIWG.

G-protein-coupled receptors (GPCRs), the largest family of integral membrane proteins, participate in the regulation of many physiological functions and are the targets of approximately 30% of currently marketed drugs. Here is the latest research.

Glial cells within the brain, particularly astrocytes and microglia, support synaptic transmission and neuron-glial circuit through the secretion of signaling molecules. The network of communication between glial cells and neurons is highly complex yet organized. Here is the latest research on glia and synaptic circuits.

The hypothalamus has received significant attention in this regard given its ability to influence feeding behavior, yet organisms rely on a much broader diversity and distribution of neuronal networks to regulate both energy intake and expenditure. Here is the latest research on the hypothalamus and feeding.

This feed focuses on the molecular organization of synapses between two nerve cells, synaptic signal transduction, and synaptic vesicles. Here is the latest research on organization of synapses.

Myelin surrounds axons and is important for efficient axonal function. Formation of myelin is regulated by many signaling pathways. Degeneration is a target for many diseases, particularly in multiple sclerosis and regeneration is associated with oligodendrocyte progenitor cells. Here is the latest research on myelin formation and repair.

The NDMA receptor is an ionotropic receptor that is activated when glutamate or glycine binds to it, initiating several downstream signaling cascades. NDMA receptor signaling is thought to be implicated in different pathologies, including depression. Here is the latest research on NDMA receptor signaling.

Calcium plays an important role in neuronal signalling, acting as a secondary messenger, depolarization of neuronal membrane and synaptic vesicle activity and release of neurotransmitters. Here is the latest research on neuronal calcium signalling.
