B Contributes to Infarction After Permanent Focal Ischemia
B (NF-
B) may induce expression of either proinflammatory/apoptotic genes or antiapoptotic genes. Because a considerable number of middle cerebral artery occlusions (MCAOs) in humans are not associated with reperfusion during the first 24 hours, the role of NF-
B after permanent MCAO (pMCAO) was investigated.
B-driven
-globin reporter were exposed to pMCAO, and the expression of the reporter gene was quantified with real-time polymerase chain reaction. Mice lacking the p50 subunit of NF-
B and wild-type controls were exposed to pMCAO with or without treatment with pyrrolidinedithiocarbamate (PDTC), an NF-
B inhibitor. Brain sections of human stroke patients were immunostained for the activated NF-
B.
B transcriptional activity to 260% (36.9±4.5 compared with 14.4±2.6; n=10; P<0.01) in the brain; this NF-
B activation was completely blocked by PDTC (17.2±2.6; n=9; P<0.05). In p50-/- mice, pMCAO resulted in 41% (18±3.2 mm3; n=12) smaller infarcts compared with wild-type controls (32.9±3.8 mm3; n=9; P<0.05), which was comparable to the protection achieved with PDTC in wild-type mice (19.6±4.2 mm3; n=8). Pro-DTC, a PDTC analogue that does not cross the blood-brain barrier, had no effect, even though Pro-DTC and PDTC were equally protective in vitro. During the first 2 days of human stroke, NF-
B was activated in neurons in the penumbral areas.
B is induced in neurons during human stroke, and activation of NF-
B in the brain may contribute to infarction in pMCAO.
