Cytosolic phospholipase A2 is induced in reactive glia following different forms of neurodegeneration.

Many recent studies have emphasized the deleterious role of inflammation in CNS injury. Increases in free fatty acids, eicosanoids, and products of lipid peroxidation are known to occur in various conditions of acute and chronic CNS injury, including cerebral ischemia, traumatic brain injury, and Alzheimer's disease. Although an inflammatory response can be induced by many different means, phospholipases, such as cytosolic phospholipase A(2) (cPLA(2)), may play an important role in the production of inflammatory mediators and in the production of other potential second messengers.

Sulfated glycoprotein-2 expression increases in rodent brain after transient global ischemia.

Sulfated glycoprotein-2 (SGP-2) is emerging as a prominent marker of neurodegeneration in mammalian brain. Regulation of brain SGP-2 was studied in adult male Wistar rats subjected to 30 min of forebrain ischemia by four vessel occlusion. By 3 days after the ischemic insult, SGP-2 RNA levels were increased two fold in caudate nucleus and hippocampus.
