Microglia Cyclooxygenase

Microglia COX-2 activity was demonstrated by COX-2 protein expression and COX-2-dependent PGE 2 production in freshly isolated microglia from IC tumors Because cultured C6 glioma cells and s c C6 tumors expressed very low levels of COX-2 these results implied that microglia which are only present in IC tumors were a major source of PG production in this glioma model To examine the
