During cerebral ischemia, the activated NF-κB dimers are subsequently translocated into the nucleus where they selectively bind to specific DNA sequences called κB sites; promoter domains present a large number of proinflammatory genes and subsequently cause TNF-α, IL-1β, IL-6, ICAM-1, PGE2, COX-2, and iNOS translation [6, 105, 106]. This evidence concerns the gene NOS2 and brain ischemia.
