cyclooxygenase-2; an enzyme that catalyzes the formation of prostaglandins from arachidonic acid.

an enzyme that makes prostaglandins that cause inflammation and pain and fever; "the beneficial effects of Nsaids result from their ability to block Cox-2"

An enzyme found in only a few places, such as the brain and parts of the kidney. It is made only in response to injury or infection. It produces prostaglandins involved in inflammation and the immune response. NSAIDs act by blocking COX-2. Because elevated levels of COX-2 in the body have been linked to cancer, scientists are investigating whether blocking COX-2 may prevent or treat some cancers.

An abbreviated form Cyclooxygenase-2, which is an enzyme that causes pain and discomfort in inflamed and feverish tissues

See cyclooxygenase-2 listed below.

One form of the cyclooxygenase enzyme. COX-2 enzymes are often produced during inflammatory responses and are responsible for the synthesis of prostaglandins that mediate inflammation.

Cyclooxygenase-2, a protein acts as an enzyme and specifically catalyzes (speeds) the production of certain chemical messengers called prostaglandins. Some of these messengers are responsible for promoting inflammation. When Cox-2 activity is blocked, inflammation is reduced. Unlike cox-1, cox-2 is active only at the site of inflammation, not in the stomach.
