Chaitali Ghosh Laboratory

Research

Our laboratory conducts cerebrovascular research to better understand brain physiology and function in neurological disorders (e.g., epilepsy and epilepsy with other comorbidities such as stroke or depression), with a focus on the blood-brain barrier.

We investigate the mechanisms and pathophysiological alterations that could contribute to disease progression and/or impede drug bioavailability across the dysfunctional blood-brain barrier. We study drug-metabolizing enzymes (e.g., cytochrome P450 enzyme, UDP-glucuronosyltransferase), drug transporters (e.g., P-glycoprotein/MDR1, multidrug resistance-associated proteins), nuclear receptors (e.g., glucocorticoid nuclear receptor, pregnane xenobiotic nuclear receptor), and other regulatory factors that control pharmacokinetic and pharmacodynamic phenomena during drug biotransformation in disease states. We also investigate the consequence of metabolic disturbances at the blood-brain barrier in epilepsy and other neurological disorders.

With a multidisciplinary team of clinicians, neurosurgeons and neuroscientists, we investigate the factors contributing to drug resistance in patients suffering from epilepsy. We use multifaceted approaches to study the neurovascular properties ex vivo and in vitro using a humanized dynamic neurovascular unit established with primary brain cells isolated from resected brain tissues post-epilepsy surgery, and in vivo by using rodent models of seizure/epilepsy.

The long-term goal of these studies is to develop a screening platform for pharmacological compounds, including drugs, across the blood-brain barrier. We also strive to identify novel therapeutic targets and potential biomarkers in the brain and vasculature for improving drug efficacy.
