A Novel Nonsurgical Approach to Treat Post-Traumatic Hydrocephalus

Abstract

The main objective of this exploratory proposal is to develop and validate a novel pharmacological strategy for the management of hydrocephalus caused by traumatic brain injury (TBI). Our objective in this application is to prove/refute the central role played by efflux transporters (ABCB1 and/or ABCG2) in the development of PTH. Our central hypothesis is that macromolecules are eliminated out of the brain primarily by efflux transporters (ABCB1 and/or ABCG2) and a slower clearance results in PTH due to excess macromolecules remaining in the ventricular CSF.Our experiments done so far are supportive of our central hypothesis that macromolecules are eliminated out of the brain byABCB1. Our results show that ABCB1 knockout animals had a statistically significant increased ventricular volume and increased clearance times for macromolecules compared to normal animals using intraventricular hemorrhage hydrocephalus model. ABCB1 overexpressed animals had a statistically significant smaller ventricular volume and faster clearance times for macromolecules compared to normal animals using intraventricular hemorrhage hydrocephalus model. Further experiments to get the numbers to 12 in each group needs to be done. In addition, we have to conduct experiments to evaluate the role of other efflux transporters (ABCG2).
