Widespread cortical expression of MANF by AAV serotype 7: localization and protection against ischemic brain injury.

ABSTRACT: Mesencephalic astrocyte-derived neurotrophic factor (MANF) is a secreted protein which reduces endoplasmic reticulum (ER) stress and has neurotrophic effects on dopaminergic neurons. Intracortical delivery of recombinant MANF protein protects tissue from ischemic brain injury in vivo. In this study, we examined the protective effect of adeno-associated virus serotype 7 encoding MANF in a rodent model of stroke. An AAV vector containing human MANF cDNA (AAV-MANF) was constructed and verified for expression of MANF protein. AAV-MANF or an AAV control vector was administered into three sites in the cerebral cortex of adult rats. One week after the vector injections, the right middle cerebral artery (MCA) was ligated for 60min. Behavioral monitoring was conducted using body asymmetry analysis,
