Cells in the brain called pericytes that have not been high on the list of targets for treating diseases like Alzheimer's may play a more crucial role in the development of neurodegenerative diseases than has been realized. The findings, published Nov. 4 in Neuron, cast the pericyte in a surprising new role as a key player shaping blood flow in the brain and protecting sensitive brain tissue from harmful substances.
For 150 years these cells have been known to exist in the brain, but we haven't known exactly what they are doing in adults,said Berislav Zlokovic, M.D., Ph.D., the neuroscientist who led the research at the University of Rochester Medical Center.
In the most recent findings from Zlokovic's laboratory, the two first authors who contributed equally to the research, graduate student Robert Bell and M.D./Ph.D. and Neuroscience student Ethan Winkler, teased out the role of the pericyte in the process. Pericytes ensheath the smallest blood vessels in the brain, wrapping around capillaries like ivy wrapping around a pipe and helping to maintain the structural integrity of the vessels.

The University of Rochester Medical Center has received $15 million in federal bioterrorism funding that allows investigators to build on several discoveries made during the past five years to improve the ability to treat radiation injuries, especially from an act of terrorism.
URMC was awarded an initial grant of $21 million in 2005 to become part of a national research network, Centers for Medical Countermeasures Against Radiation. The centers were charged with researching how best to respond to a dirty bomb or other radiological or nuclear attack.
A second, $15 million, five-year award, received this month from the National Institutes of Health/National Institute of Allergy and Infectious Disease, will allow URMC researchers to focus on testing known drugs and experimental agents and their ability to ward off systemic radiation injury that affects the lungs, brain, skin and bone marrow.

Youngsun Cho is Awarded NRSA Individual Training Grant
Youngsun Cho, a first year MSTP student in the Fudge Lab was recently awarded a Ruth Kirschstein National Research Service Award (F30) for three years of training. Youngsun's proposed studies involve examining circuitry that may underlie modulation of approach behavior in anxious adolescents. She will first detail connections between specific regions of the prefrontal cortex the amygdala in animals, based on her work in Rochester. This data will then be used to design studies investigating functional connectivities between these regions in anxious adolescents. The latter studies are being conducted in partnership with Dr. Monique Ernst at the NIMH intramural program.

MD/PhD student Youngsun Cho leaves to begin "mini-sabbatical" training at NIMH
Youngsun Cho, an MD/PhD student in the laboratory of Dr. Julie Fudge, leaves to begin "mini-sabbatical" training in functional MRI and studies in anxious adolescents at with colleagues at NIMH. Youngsun is interested in structural and functional brain connections that influence reward and punishment anticipation in adolescents, and she will take anatomical studies from the laboratory to the next phase of her training with Dr. Monique Ernst in the Section on Mood and Anxiety Disorders at NIMH.

MD/PhD Student Danielle deCampo Wins URMC CTSI Travel Award
Danielle deCampo, an MD/PhD student in the laboratory of Dr. Julie Fudge, has won a URMC CTSI Travel Award. Danielle will now be able to pursue training opportunities in performing laser capture microscopy and microarray analysis with collaborators at University of Pittsburgh. This is an opportunity to add to her "technical toolbox" as she tries to characterize specific neuronal populations that may play a role in mood disorders.

Jacqueline Williams, Major Lab Collaborator, Chairs National Space Biomedical Research Institute Science Committee
Jacqueline Williams, Ph.D., was named chair of the National Space Biomedical Research Institute's Scientific Advisory Committee for its Center of Acute Radiation Research. Williams is grant director and core leader of the Center for Biophysical Assessment and Risk Management Following Irradiation at the University of Rochester Medical Center.
NSBRI is a NASA-funded consortium of institutions studying the health risks related to long-duration spaceflight and developing countermeasures to mitigate the risks. The CARR, which is headed at the University of Pennsylvania School of Medicine, is responsible for studying the acute effects of exposure to space radiation during exploration missions. The Scientific Advisory Committee provides advice on the Center's productivity and effectiveness.
