A neurotoxin found in snake venom allowed researchers to uncover a detailed shape of nicotinic receptors involved in muscle contractions.
Researchers report alpha 7 nicotinic acetylcholine receptors enhance communication between the hippocampus and frontal cortex, where as a4b7 nicotinic receptors decrease the communication. The findings may have implications for the way stimulation of acetylcholine can be used to treat dementia.
Researchers have crystallized a protein that could hold the answer as to how nicotine addiction occurs in the brain.
Researchers have discovered blocking the B2 subunit of nicotinic receptors can prevent memory loss associated with Alzheimer's disease.
