Delivering treatments to diseases that affect primarily the brain has proven difficult. This is due to the specialized nature of blood vessels of the brain that do not permit the entry of substrates in blood except nutrients and oxygen. Such controlling is necessary for normal brain functioning since brain cells are sensitive to even small changes in their environment. However, under disease conditions such as stroke, traumatic brain injury and brain tumors, most drug molecules also are blocked from entering the brain making timely drug delivery to these diseases nearly impossible. As a result, these patient populations have high mortality rates. The status of neuronal cells in these diseases has been the focus of past research, but now we want to home in on the interactions between neuronal cells, their blood supply and other supporting cells in their vicinity to clarify the disease processes. Such interactions can be unique to a given altered brain condition and need to be understood in the context of that disease, but our findings may offer a broader range of treatment targets. For the past 20 years, my research has focused on understanding the changes in the brain blood vessel function using animal models of stroke and brain tumors. As a neuroscientist, I have a broad background in magnetic resonance imaging (MRI) of the brain, quantitative autoradiography and fluorescence microscopy. These are combined with a variety of histological and biochemical methods with improved functional outcome as the primary endpoint. Some of the MRI methods that we’ve developed to scan animal brains have been used in translational studies for human brain imaging. My research has primarily focused on: 1) the vascular pathophysiology of stroke and primary brain tumors such as glioma; 2) vascular protective therapies for stroke; and 3) mechanisms of vascular normalization to improve drug delivery to brain tumors.
