Golden Anniversary of the Nicotinic Receptor [PDF]
The high-resolution structure of the nicotinic acetylcholine receptor from Torpedo electric tissue in association with the snake toxin α-bungarotoxin (Rahman et al., 2020) is presented 50 years after its identification as the first neurotransmitter receptor and ligand-gated ion channel.

Background Nicotinic and muscarinic acetylcholine receptors likely evolved in the cnidarian–bilaterian common ancestor. Both receptor families are best known for their role at chemical synapses in bilaterian animals, but they also have described roles as

CHRNA5 links chandelier cells to severity of amyloid pathology in aging and Alzheimer’s disease
Changes in high-affinity nicotinic acetylcholine receptors are intricately connected to neuropathology in Alzheimer’s Disease (AD). Protective and cognitive-enhancing roles for the nicotinic α5 subunit have been identified, but this gene has not been ...

Phospholipases A2 represent the most abundant family of snake venom proteins. They manifest an array of biological activities, which is constantly expanding. We have recently shown that a protein bitanarin, isolated from the venom of the puff adder Bitis

Weekly submission of rats to active avoidance apparatus can be considered a neurostimulation strategy, once it can improve memory and can increase the density of receptors from different neurotransmitter systems in brain areas related to memory.

Simultaneous Comparison of Nicotinic Receptor Antagonists on Three Nicotinic Acetylcholine Receptors
AbstractThe relative potencies of several nicotinic cholinoceptor antagonists in producing tetanic fade and reduction of striated muscle contraction were investigated in the isolated guinea-pig oesophagus as well as the guinea-pig and rat phrenic nerve-diaphragm preparations.

Neurotransmitter regulation of neural development: acetylcholine and nicotinic receptors
Several neurotransmitter systems have been related to developmental processes during the past decade. In this review, we discuss the evidence that the nicotinic acetylcholine receptors could have an additional function during development that may be ...

Nitrosamines as nicotinic receptor ligands [PDF]
Nitrosamines are carcinogens formed in the mammalian organism from amine precursors contained in food, beverages, cosmetics and drugs. The potent carcinogen, NNK, and the weaker carcinogen, NNN, are nitrosamines formed from nicotine. Metabolites of the nitrosamines react with DNA to form adducts responsible for genotoxic effects. We have identified NNK

Evolution of vertebrate nicotinic acetylcholine receptors
Background Many physiological processes are influenced by nicotinic acetylcholine receptors (nAChR), ranging from neuromuscular and parasympathetic signaling to modulation of the reward system and long-term memory.
