The acetylcholine produced by the nucleus basalis is transferred to other regions of the brain, where it is "recognised" by receptor molecules.

...stablished that the ATP signals blood platelets to produce nitric oxide (NO). That messenger molecule has a variety of functions, including dilating blood vessels. When released from platelets, NO helps regulate platelets activity, preventing excessive clotting. Disruption of the RBC-platelet communication...HWI researchers determine structure of protein from pathogen associated with CF and TB

.... Mimicking the plants themselves, the aphids also produce an enzyme called myrosinase, which is stored in the muscles of their head and thorax. In the event of a predator attack this enzyme in the muscles comes into contact with the glucosinolates in the blood, catalysing a violent chemical reaction which r...A compound from olive-pomace oil gets 80 percent slowing down of HIV spread
