Research

The founding members of the Hydrocephalus Research Center are all colleagues and collaborators on two Department of Defense grants supporting preclinical studies targeted to developing drug treatments using genetic and induced (post-hemorrhagic and post-traumatic) forms of hydrocephalus in rodents and in a pig model of post-hemorrhagic hydrocephalus.

To date, the potential treatments target CSF production, neuroinflammation and neuronal cell protection. The proposed experiments will also explore co-therapy of agents targeting multiple aspects of hydrocephalic development and associated sequelae such as changes in cognition, vision, pain and gait disturbances.

Hydrocephalus is a devasting disease for which there are no pharmaceutical treatments.

Currently the standard of care involves brain surgery—most usually the placement of a shunt to drain excess cerebrospinal fluid (CSF) from the brain to another area of the body. However, shunts routinely fail for a variety of reasons including infection, blockage and equipment malfunction predisposing the patient to multiple brain surgeries.

While pediatric hydrocephalus is perhaps the most recognizable form, there are multiple causes of this condition in older children and adults including traumatic brain injury, stroke, infection and genetic predisposition. Regardless of the precipitating factors, there is an excess of CSF in the brain and an enlargement of the cerebral ventricles.

It is our hypothesis that pharmaceuticals that could decrease CSF production on an as-needed basis would be helpful in treating most forms of hydrocephalus. Alternatively, pharmaceuticals that target aspects of the pathological changes such as inflammation and neuronal cell death would also be beneficial. Rational drug design for such potential treatments is based on a more detailed understanding of the production of CSF by the choroid plexus epithelium as well as the pathological changes that occur in response to the precipitating causes. The small tissue comprising the choroid plexus produces approximately 500 ml of CSF per day, the composition of which varies according to physiological, diurnal, and pathophysiological influences. The pathological changes likely include production of toxic intermediates, inflammation, changes in fluid electrolyte homeostasis, and ultimately, cell damage and death.

IU’s Bonnie Blazer-Yost and colleagues are working to identify a new drug treatment for hydrocephalus, a condition commonly associated with complications from traumatic brain injury.

Description of the video:

Hydrocephalus is a build up of the cerebral spinal fluid inside of the brain. People are most familiar with it in the pediatric population, and there it is about one in a thousand most common in premature infants. But what people don't realize is that it is a similar problem in adults. Currently, the only treatment for hydrocephalus is brain surgery. Our ultimate goal is to find a drug that we can use to treat hydrocephalus. I'm Bonnie Blazer-Yost. I am a professor of biology in the School of Science here at IUPUI. And what we're studying in the brain is what are the processes that cause the production of cerebral spinal fluid? And analogous question would be, what goes wrong? And is there some step where we can intervene with a potential drug? The DOD is interested in this, as you might well imagine, because of traumatic brain injury. The active duty military, of course, are most prone to the post-traumatic form of hydrocephalus. The DOD veteran population is like all populations, aging. So the normal pressure hydrocephalus is important to them as well. In talking with our colleagues we realized that there's probably a lot of commonality. We thought it would be nice to have a center to bring all of this together. It has become a point of collaboration across campus. The neuroscience units on campus, particularly the medical school, have shown interest. We're hoping that the center is a conduit for bringing people together here in Indianapolis, because having our clinical colleagues join us is very, very powerful to have multiple views of hydrocephalus and how we might approach treatment options.

Hydrocephalus Research Symposium

Watch the full presentation of the Hydrocephalus Research Symposium from Friday, November 3, 2023.

Bonnie Blazer-Yost, Ph.D.
Professor of Biology, IU Indianapolis
Director, Hydrocephalus Research Center

Prof. Blazer-Yost is a transport physiologist whose main research interest is the regulation of epithelial ion transport particularly in response to stimuli such as hormones and other effectors. Her laboratory studied polycystic kidney disease (PKD) particularly the mechanisms underlying the growth of cysts. In the PKD field, she has experience in taking a potential drug treatment (PPARg agonists) from an initial observation in cultured cell studies, through animal models and into a human clinical trial for which she was a Co-PI. Currently, the focus of this laboratory is studying the mechanisms of hydrocephalic development in a variety of preclinical models with a view to developing a drug treatment for hydrocephalus. She is the corresponding PI of two large DoD grants supporting preclinical drug development for hydrocephalus.

Dr. Jantzie is a neuroscientist and neuropharmacologist dedicated to the pathophysiology of brain injury and its sequela. She is an expert in neural-immune communication and inflammatory signal transduction. In addition to studying neurorestoration in hydrocephalus, her lab is examining the intersection of brain and peripheral inflammation and immune activation. Together with high-resolution neuroimaging of functional and anatomical connectivity, and touchscreen cognitive assessment, she uses a sophisticated clinical biomarker detection and identification platform in her work to quantify inflammatory proteins in biological fluids and tissues.

Dr. Belecky-Adams is a vision biologist specializing in retinal health and disease. Dr. Belecky-Adams is an expert in factors that trigger astrogliosis and microgliosis in retinal disease and determining a role for inflammation in diabetic retinopathy. Her laboratory has discovered the role of a cilia protein in photoreceptor development and degeneration using the rapidly progressing Tmem67-/- rat hydrocephalus model. She is using preclinical rat models of hydrocephalus to study papilledema and vision problems associated with the disease.

PI of projects 1 and 3

Dr. Robinson is a pediatric neurosurgeon who cares for children and adults with hydrocephalus. She is internationally recognized as an expert in posthemorrhagic hydrocephalus and consequences of brain injury, including trauma. Dr. Robinson brings extensive expertise in development of clinically relevant brain injury models, oligodendrocyte biology and mechanism of brain injury and repair. Her research on neurorepair with erythropoietin (EPO) provided mechanistic support for the translation of EPO into clinical trials for preterm infants.
