Nitric oxide is an unusual gaseous signaling molecule that diffuses freely across membranes rather than acting at classical receptors. In blood vessels it drives relaxation and increased blood flow (including in the brain and during erection), and in the nervous system it acts as a retrograde messenger supporting synaptic plasticity and learning. It also contributes to immune defense.
