Cyclooxygenase-2 (COX-2) in inflammatory and degenerative brain diseases.
Cyclooxygenase (COX) catalyses the first committed step in the synthesis of prostanoids, a large family of arachidonic acid metabolites comprising prostaglandins, prostacyclin, and thromboxanes, and is a major target of non-steroidal anti-inflammatory drugs (NSAIDs). COX exists as constitutive and inducible isoforms. COX-2 is the inducible isoform, rapidly expressed in several cell types in res...
متن کاملCyclooxygenase-2 (COX-2) overexpression in childhood brain tumors.
The overexpression of COX enzymes has been demonstrated in human neoplasms at various sites, including the colon, gastrointestinal tract, lung, skin and recently in brain tumors. In this study, COX-2 receptor overexpression in primary childhood brain tumors was determined and the distribution pattern of COX-2 receptors was examined. A sensitive, 4-step, alkaline phosphatase conjugated antigen d...
متن کاملCyclooxygenase-2 (COX-2) Inhibition Constrains
Indoleamine 2,3-dioxygenase 1 (IDO1) metabolizes L-tryptophan to kynurenines (KYN), inducing T-cell suppression either directly or by altering antigen-presenting-cell function. Cyclooxygenase (COX)-2, the rate-limiting enzyme in the synthesis of prostaglandins, is over-expressed by several tumours. We aimed at determining whether COX-2 inhibitors down-regulate the IFN--induced expression of ID...
متن کاملUse of nonsteroidal anti-inflammatory drugs and cyclooxygenase-2 (COX-2) inhibitors: indications and complications.
Nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most widely used medications-both prescription and over the counter-in the United States. Gastrointestinal side effects from NSAIDs are responsible for significant patient morbidity and mortality as well as healthcare cost. With the development of cyclooxygenase-2 (COX-2) specific inhibitors, these serious adverse reactions have been s...
متن کاملRegional Differences in the Neuronal Expression of Cyclooxygenase-2 (COX-2) in the Newborn Pig Brain
Cyclooxygenase (COX)-2 is the major constitutively expressed COX isoform in the newborn brain. COX-2 derived prostanoids and reactive oxygen species appear to play a major role in the mechanism of perinatal hypoxic-ischemic injury in the newborn piglet, an accepted animal model of the human term neonate. The study aimed to quantitatively determine COX-2 immunopositive neurons in different brain...
