University Research Award helps team explore regeneration in a critical layer of the cornea

The structure of the cornea.

On the backside of the cornea is a single layer of cells that plays an all-important role, maintaining just the right fluid balance to keep the cornea transparent so that light can enter the eye. Until recently, it was believed this layer, called the corneal endothelium, is incapable of replacing its damaged cells. As more cells become damaged, the cornea becomes opaque, leading to loss of vision and, ultimately, to as many as 30,000 endothelium transplants a year in the United States alone.
A team of University researchers is exploring the possibility that stem cells on the outer edges of the cornea, given the right stimulation, can migrate into the endothelium to replace damaged cells. (Undifferentiated stem cells develop into specialized cells.) The work raises the possibility of restoring vision without the need for transplants.
The team is led by Amy Kiernan, associate professor of ophthalmology, and includes Jannick Rolland, the Brian J. Thompson Professor of Optical Engineering; Patrice Tankam, a senior scientist in the Center for Visual Science; Changsik Yoon, a graduate student in Rolland’s lab; Rebecca Rausch, a graduate student in Kiernan’s lab; and Holly Hindman, former associate professor of ophthalmology, now in private practice but still consulting on the project. They are supported with a $75,000 University Research Award. The URA program is designed to help researchers develop preliminary data or proof of concept needed to leverage larger federal or foundation awards to carry a promising project to completion.
There have been tantalizing clinical hints that the corneal endothelium may have regenerative capabilities, Kiernan says. For example, there have been cases in which endothelial transplants failed to engraft, but the cornea cleared up anyway, with regeneration of the endothelium occurring on its own. “So it seems that if something is done that stimulates a progenitor or stem cell population, most likely those in the periphery of the cornea, there is some regenerative capacity in the endothelium – just based on clinical studies,” Kiernan says.
Her team will attempt to identify the potential stem cells that might be stimulated to migrate to the endothelium to repair damage. They will use mouse models from Kiernan’s lab in which adult stem cells can be permanently tagged with fluorescent biomarkers and tracked even after they differentiate into other cells. The identification and tracking of those cells will be done by refining a novel imaging approach developed in Rolland’s lab. Called Gabor domain optical coherence microscopy, the technology allows rapid, noninvasive imaging of cellular structures beneath the surface of the skin or within the human eye – in greater detail than traditional imaging with optical coherence tomography.
“Think of it as a high-definition, volumetric imaging,” Rolland says. “But we also want to know what kind of cells we are looking at, so we are integrating fluorescence imaging with the high-definition volumetric microscopy so we can do both.” The team represents a combination of pertinent expertise: cell development and regeneration (Kiernan and Rausch), imaging (Rolland, Tankam, and Yoon), and the biological basis for corneal and ocular surface diseases in humans (Hindman). The University Research Award funding is helping support graduate students and technicians working on the project, and the cost of mice and supplies. “Pilot funding like this is so important, especially with NIH grants shrinking,” Kiernan says.
“It’s really helpful to be able to bridge this kind of interdisciplinary effort,” says Rolland. “You need to work together a little bit to understand the challenges involved and what you need to do to secure preliminary data, to show we have a pathway.
“It takes time to get data, so even a small grant that provides a bridge for a year or two can make a huge difference.”

Nina Schor, M.D., Ph.D., William H. Eilinger Chair of Pediatrics at the University of Rochester Medical Center (URMC), will step down as chair in June 2017. Schor served 11 years as pediatrician-in-chief at UR Medicine’s Golisano Children’s Hospital, and under her leadership, the Department of Pediatrics fulfilled a decades-long dream of building a standalone children’s hospital in Rochester; the new facility opened its doors to patients in July 2015. "I don’t want to downplay the significance of the new hospital, but it’s really what we do inside of it and because of it that’s so important,” said Schor. “I look at the academic physicians and physician scientists who came to Rochester with just a dream and a fire in their belly and how they’ve now brought those dreams to fruition — that’s what I’m most proud of.”
The Department of Pediatrics grew from 110 faculty members to over 170 during Schor’s tenure, creating new divisions in palliative care, sleep medicine, allergy, and hospitalist medicine. Research centers focused on premature infants, translational molecular programs, and red blood cell development also developed under Schor’s leadership.
“Not only was the new hospital built under Nina’s leadership, but she truly championed the project, ensuring that every detail was designed with patients and families in mind,” said Mark Taubman, M.D., URMC CEO and Dean of the School of Medicine and Dentistry. “She has been the face of the children’s hospital and inspired trust in our families, physicians, and donors at a time when we very much needed the community’s support.”Read More: Nina Schor to Step Down as Children's Hospital Pediatrician-in-Chief

Studies going back several years have shown that playing action video games (AVG) can help improve visual acuity. A new study by vision scientists at the University of Rochester and Vanderbilt University found that children with poor vision see vast improvement in their peripheral vision after only eight hours of training via kid-friendly video games. Most surprising to the scientists was the range of visual gains the children made, and that the gains were quickly acquired and stable when tested a year later.
“Children who have profound visual deficits often expend a disproportionate amount of effort trying to see straight ahead, and as a consequence they neglect their peripheral vision,” said Duje Tadin, associate professor of brain and cognitive sciences at Rochester. “This is problematic because visual periphery—which plays a critical role in mobility and other key visual functions—is often less affected by visual impairments.”
“We know that action video games (AVG) can improve visual perception, so we isolated the AVG components that we thought would have the strongest effect on perception and devised a kid-friendly game that compels players to pay attention to the entire visual field, not just where their vision is most impaired,” said Tadin, who is also a professor in the Center for Visual Science. “As a result, we’ve seen up to 50 percent improvement in visual perception tasks.”Read More: Brain training video games help low-vision kids see better

Researchers at the University of Rochester Medical Center believe they have identified a new means of enhancing the body’s ability to repair its own cells, which they hope will lead to better diagnosis and treatment of traumatic nerve injuries, like those sustained in car accidents, sports injuries, or in combat. In a study published today, the team showed that a drug previously approved for other purposes can ‘wake up’ damaged peripheral nerves and speed repair and functional recovery after injury.
The study appearing in EMBO Molecular Medicine, demonstrates for the first time that 4-aminopyridine (4AP), a drug currently used to treat patients with the chronic nerve disease, multiple sclerosis, has the unexpected property of promoting recovery from acute nerve damage. Although this drug has been studied for over 30 years for its ability to treat chronic diseases, this is the first demonstration of 4AP’s benefit in treating acute nerve injury and the first time those benefits were shown to persist after treatment was stopped.
Study authors, John Elfar, M.D., associate professor of Orthopaedics, and Mark Noble, Ph.D., Martha M. Freeman, M.D., Professor in Biomedical Genetics, and their laboratory team, found that daily treatment with 4AP promotes repair of myelin, the insulating material that normally surrounds nerve fibers, in mice. When this insulation is damaged, as occurs in traumatic peripheral nerve injury, nerve cell function is impaired. These researchers found that 4AP treatment accelerates repair of myelin damage and improvement in nerve function.Read More: Repurposed Drug May Offer Diagnosis, Treatment for Traumatic Nerve Damage

A new award from the CHDI Foundation will advance promising research that aims to slow the progression of Huntington’s disease. The funding, anticipated to total more than $10.5 million over next five years, will help University of Rochester Medical Center (URMC) scientists develop a stem cell-based therapy that swaps sick brain cells for healthy ones.
The new award will go to the lab of Steve Goldman, M.D., Ph.D., the co-director of the URMC Center for Translational Neuromedicine, which has research operations in both Rochester and at the University of Copenhagen.
Huntington’s is a hereditary neurodegenerative disease characterized by the loss of medium spiny neurons, a nerve cell in the brain that plays a critical role in motor control. As the disease progresses over time and more of these cells die, the result is involuntary movements, problems with coordination, and cognitive decline, depression, and often psychosis. There is currently no way to slow or modify this fatal disease.
The new award will support research that builds upon findings published by Goldman earlier this year in the journal Nature Communications showing that researchers were able to slow the progression of the disease in mice by transplanting healthy human support cells, called glial progenitor cells, into the animals’ brains.Read More: Research Will Explore New Therapies for Huntington’s Disease

Maiken Nedergaard, M.D., D.M.Sc.
More than $4.5 million in new grants to the lab of University of Rochester Medical Center scientist Maiken Nedergaard, M.D., D.M.Sc., underscore the important role the brain’s waste disposal system may play in a range of neurological disorders. The new awards will advance understanding of how small vessel disease and traumatic brain injury can give rise to cognitive and behavioral problems.
Nedergaard and her colleagues first unveiled the brain’s unique method of removing waste – dubbed the glymphatic system – in a paper in Science Translational Medicine in 2012. The research revealed that the brain possesses a circulation network that piggybacks on blood vessels and uses cerebral spinal fluid to flush away waste products from brain tissue. Since that time, the team has gone on to show that the glymphatic system works primarily while we sleep, could be a key player in diseases like Alzheimer’s, and is disrupted after traumatic brain injury.Read More: New Grants Explore Role of Brain’s “Garbage Truck” in Mini-Stokes and Trauma

Aggressive forms of neuroblastoma contain a specific protein in their cells’ nuclei that is not found in the nuclei of more benign forms of the cancer, and the discovery, made through research from the University of Rochester Medical Center (URMC), could lead to new forms of targeted therapy.
EYA1, a protein that contributes to ear development, is present in the cytoplasm of many neuroblastoma tumors, but this protein migrates to the nucleus in the cells of more aggressive forms of the disease. The research, recently published in two medical research journals, allows for the development of targeted drugs that will work to prevent the neuroblastoma from reaching this more aggressive stage; researchers at URMC and elsewhere have already begun testing some of these potential treatments in a laboratory setting.
“Neuroblastoma is one of the most common and deadly forms of childhood cancer, and this discovery allows us to identify drugs that prevent the change in EYA1 structure and potentially minimize the danger to a child who has this disease,” said Nina Schor, M.D., Ph.D., professor of Pediatrics and Neuroscience and the William H. Eilinger Chair of Pediatrics at URMC.

Harris Gelbard Receives International Award for Neurovirology Research
Tuesday, September 13, 2016
Harris “Handy” Gelbard, M.D., Ph.D., director of the Center for Neural Development & Disease, is slated to receive the Hilary Koprowski Prize in Neurovirology at this year’s International Symposium on Molecular Medicine and Infectious Disease at Drexel University. Gelbard will be recognized for developing an unconventional drug that shows promise in treating brain disorders associated with HIV.
Gelbard’s drug, URMC-099, calms the immune system when it goes awry, as happens in HIV Associated Neurocognitive Disorder (HAND). In HAND, immune reactions to HIV particles in the brain damage nerve cells and cause dementia. Because patients affected by HAND also have HIV, it was imperative that URMC-099 not interfere with the antiretroviral drugs that keep HIV-positive patients alive.

A $2.3 million Department of Defense grant will help neuroscientists develop new treatments for the emergency room and the battlefield. The research will focus on the development of new therapies that could help protect brain and other at risk organs following a trauma, heart attack, or stroke.
“While we have made significant progress in our ability to restore blood flow after stroke or cardiac arrest, the medical community does not have drugs at its disposal to prevent the secondary damage that occurs after these events,” said University of Rochester Medical Center neurologist Marc Halterman, M.D., Ph.D., the principal investigator of the study. “This grant will further our research on a promising class of drugs that possess both anti-inflammatory and cytoprotective properties that we believe will be suitable for use in both military and emergency conditions.”Read More: DOD Grant Explores New Drugs to Thwart Impact of Trauma, Stroke, and Cardiac Arrest

Over the typical course of Rett syndrome, initial language and communication abilities deteriorate dramatically between the ages of 1 and 4 years, and a majority of these children go on to lose all oral communication abilities. It becomes extremely difficult for clinicians and caretakers to accurately assess the level of preserved auditory functioning in these children, an issue of obvious clinical import. Non-invasive electrophysiological techniques allow for the interrogation of auditory cortical processing without the need for overt behavioral responses. In particular, the mismatch negativity (MMN) component of the auditory evoked potential (AEP) provides an excellent and robust dependent measure of change detection and auditory sensory memory. Here, we asked whether females with Rett syndrome would produce the MMN to occasional changes in pitch in a regularly occurring stream of auditory tones.Read More: Automatic cortical representation of auditory pitch changes in Rett syndrome - John Foxe et al.

Pasternak Research Paper to be Published in J. Neuroscience
Thursday, August 4, 2016
The paper "Prefrontal Neurons Represent Motion Signals from Across
the Visual Field but for Memory-Guided Comparisons
Depend on Neurons Providing these Signals" will be published in J. Neuroscience shortly.
Visual decisions often involve comparisons of sequential visual motion that can appear at any location in the visual field. We
show that during such comparisons, the lateral prefrontal cortex (LPFC) contains accurate representation of visual motion
from across the visual field, supplied by motion processing neurons. However, at the time of comparison, LPFC neurons can
only use this information to compute the differences between the stimuli, if stimuli appear at the same retinal location,
implicating neurons with localized receptive fields in the comparison process. These findings show that sensory comparisons
rely on the interactions between LPFC and sensory neurons that not only supply sensory signals but also actively
participate in the comparison of these signals at the time of the decision.
Make sure to read the article when it comes out.

Researchers have identified an inner ear deficiency in children with Autism that may impact their ability to recognize speech. The findings, which were published in the journal Autism Research, could ultimately be used as a way to identify children at risk for the disorder at an early age.
“This study identifies a simple, safe, and non-invasive method to screen young children for hearing deficits that are associated with Autism,” said Anne Luebke, Ph.D., an associate professor in the University of Rochester Medical Center Departments of Biomedical Engineering and Neuroscience and a co-author of the study. “This technique may provide clinicians a new window into the disorder and enable us to intervene earlier and help achieve optimal outcomes.”
“Auditory impairment has long been associated with developmental delay and other problems, such as language deficits,” said Loisa Bennetto, Ph.D., an associate professor in the University of Rochester Department of Clinical and Social Sciences in Psychology and a co-author of the study. “While there is no association between hearing problems and autism, difficulty in processing speech may contribute to some of the core symptoms of the disease. Early detection could help identify risk for ASD and enable clinicians to intervene earlier. Additionally, these findings can inform the development of approaches to correct auditory impairment with hearing aids or other devices that can improve the range of sounds the ear can process.”Read More: Luebke and Bennetto Explore Hearing Test That May Identify Autism Risk
McNair Summer Scholar Ashley Bui Talks Amygdala Circuits
Friday, July 22, 2016
Congratulations to Ashley Bui, a rising senior in Brain and Cognitive Sciences, on her presentation July 22, 2016. Her talk Projections from the Temporal Cortex to the Basal Nucleus of the Amygdala in the Macaque highlighted data from her summer project in our lab. The amygdala is required for computing which of the complex sensory stimuli that an individual encounters are emotionally meaningful, so that appropriate action can be taken. Ashley’s preliminary data shows that specific portions of the temporal cortex, which are critical for processing complex visual and auditory information, communicate with different regions of the amygdala. The results suggest that cortical areas that process complex visual information on 'what' and 'where' an object is (or is moving) are communicating with specific amygdala subregions. Thus, while determining the emotional importance of ‘what or who’ is important, biologic movements also likely influence amygdala activity and coding. We are happy that she will continue this work through the Fall semester.

Sleep is critical for rest and rejuvenation. A human being will actually die of sleep deprivation before starvation--it takes about two weeks to starve, but only 10 days to die if you go without sleep.
The CDC has also classified insufficient sleep as a public health concern. Those who don't get enough sleep are more likely to suffer from chronic diseases that include hypertension, diabetes, depression, obesity, and cancer.
It's thus vital to get enough shuteye, but it turns out your sleep position also has a significant impact on the quality of rest you get.
Now, a neuroscience study suggests that of all sleep positions, one is most helpful when it comes to efficiently cleaning out waste from the brain: sleeping on your side.
The study, published in the Journal of Neuroscience, used dynamic contrast-enhanced MRI to image the brain's "glymphatic pathway." This is the system by which cerebrospinal fluid filters through the brain and swaps with interstitial fluid (the fluid around all other cells in the body).
"It is interesting that the lateral [side] sleep position is already the most popular in humans and most animals--even in the wild," said University of Rochester's Maiken Nedergaard. "It appears that we have adapted the lateral sleep position to most efficiently clear our brain of the metabolic waste products that build up while we are awake."Read More: The Sleep Hack Neuroscience Says Gives Your Brain Optimal Rest

Researchers have successfully reduced the symptoms and slowed the progression of Huntington’s disease in mice using healthy human brain cells. The findings, which were published today in the journal Nature Communications, could ultimately point to a new method to treat the disease.
The research entailed implanting the animals with human glia cells derived from stem cells. One of the roles of glia, an important support cell found in the brain, is to tend to the health of neurons and the study’s findings show that replacing sick mouse glia with healthy human cells blunted the progress of the disease and rescued nerve cells at risk of death.
“The role that glia cells play in the progression of Huntington’s disease has never really been explored,” said Steve Goldman, M.D., Ph.D., co-director of the University of Rochester Center for Translational Neuromedicine. “This study shows that these cells are not only important actors in the disease, but may also hold the key to new treatment strategies.” Read More: Swapping Sick for Healthy Brain Cells Slows Huntington’s Disease

A new study shows that repeated radiation therapy used to target tumors in the brain may not be as safe to healthy brain cells as previously assumed. The findings, which appear in the International Journal of Radiation Oncology, Biology, Physics, show that the treatment also kills important support cells in the brain and may cause as much, if not more damage, than single dose radiation therapy.
“This study suggests that conventional repeated radiation treatments offer no significant benefit to brain tumor patients,” said Kerry O’Banion, M.D., Ph.D., a professor in the University of Rochester Medical Center (URMC) Department of Neuroscience and lead author of the study. “It also shows that certain cell populations in the brain are vulnerable to radiation and this may help explain why so many brain cancer patients experience cognitive problems after treatment.” Read More: Conventional Radiation Therapy May Not Protect Healthy Brain Cells

A new study out today in the journal Translational Psychiatry sheds further light on the idea that schizophrenia is a sensory disorder and that individuals with the condition are impaired in their ability to process stimuli from the outside world. The findings may also point to a new way to identify the disease at an early stage and before symptoms become acute.
Because one of the hallmarks of the disease is auditory hallucinations, such as hearing voices, researchers have long suspected a link between auditory processing and schizophrenia. The new study provides evidence that the filtering of incoming visual information, and also of simple touch inputs, is also severely compromised in individuals with the condition.
“When we think about schizophrenia, the first things that come to mind are the paranoia, the delusions, the disorganized thinking,” said John Foxe, Ph.D., the chair of the University of Rochester Medical Center Department of Neuroscience and senior author of the study. “But there is increasing evidence that there is something fundamentally wrong with the way these patients hear, the way they feel things through their sense of touch, and in the way in which they see the environment.”Read More: When the Physical World is Unreliable: Study Finds Visual and Tactile Processing Deficits in Schizophrenia
