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 ...

A study published in Cell Stem Cell on February 5, 2026, traces a direct signaling chain from sleep-deprived brains to ...

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 ...

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 ...

More than 60% of complement inhibitor–naive patients with acetylcholine receptor–positive generalized myasthenia gravis (MG) in diverse clinical populations had a clinically meaningful reduction in MG ...

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 ...

SOME years ago, we found that scarcely any preformed acetylcholine exists in the organs of rabbit or frog 1–3. Working on organs frozen in liquid air or ethyl ether mixed with solid carbonic acid ...

For the first time, a study shows an online assessment can provide a scientific measure of acetylcholine – a key brain chemical, which declines progressively with cognitive aging and even more quickly ...

What goes on in a man’s head during sex? According to a new study from Japan, it all comes down to the precise timing of two brain chemicals: dopamine and acetylcholine. Their findings in male mice ...
