## Abstract Nitric oxide (NO) from astrocytes is one of the signalers used by the brain's extensive glial‐neuronal‐vascular network, but its excessive production by pro‐inflammatory cytokine‐stimulated glial cells can be cytodestructive. Here, we show how three pro‐inflammatory cytokines (IL‐1β, TN
