In utero intracerebroventricular delivery of adeno-associated viral vectors to target mouse choroid plexus and cerebrospinal fluid

Abstract

Summary: Experimentally targeting mouse choroid plexus (ChP) provides a valuable approach for investigating mechanisms of ChP-cerebrospinal fluid (CSF) biology. Here, we provide a protocol to deliver adeno-associated viral vectors (AAVs) by in utero intracerebroventricular (ICV) injection to ChP epithelial cells. We begin by describing steps for induction anesthesia of the pregnant dam, laparotomy, and in utero ICV injection. We also detail post-surgical care and immunoblot validation.For complete details on the use and execution of this protocol, please refer to Jang et al. (2022).1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
