Figure 1: Endocrine cells in human pancreatic islets express cholinergic markers. Figure 2: Human alpha cells express vAChT and ChAT. Figure 3: Isolated human islets secrete acetylcholine (ACh) in ...

Members of the superfamily of nicotinic acetylcholine receptors (nAChR) mediate synaptic transmission in the peripheral and central nervous systems. The nAChRs are allosteric proteins that bind ...

Acetylcholine regulates blood flow, but the source of blood acetylcholine has been unclear. Now, researchers at Karolinska Institutet have discovered that certain T cells in human blood can produce ...

Acetylcholine (ACh) rechallenge may be a novel method to improve detection of coexisting coronary spasm endotypes, and at the same time, assess the treatment response to nitrate-based therapies, a new ...

Karolinska Institutet researchers identified dopamine-acetylcholine disruptions in the basal ganglia as key contributors to autism-related behavioral inflexibility. Using advanced techniques like ...

Acetylcholine (ACh) is a neuromodulator with a central role in aversive learning - rapid conditioning to unpleasant smell, taste, or touch. These learning functions play out in cells called D2 ...

In a new study, a group of researchers, led by Dr. Joshua Goldberg from the Hebrew University, describe a new kind of neurochemical wave in the brain. Their research, published in Nature ...

Subtle changes in neurotransmission that occur during Alzheimer’s disease have been tough to track in living people. A new positron emission tomography tracer may change that. In the January 12 ...

How we process sensory stimuli from the world around us is intricately modulated so that we sense what we want and discard the rest to avoid overtaxing our neural systems. A new study reports, ...

A University of Queensland-led study has found Australian skinks have evolved molecular armor to stop snake venom from shutting down their muscles. The research has been published in the International ...
