Vollum Institute at OHSU (OHSU/Kristyna Wentz-Graff)

The Vollum Institute is a privately endowed research institute at Oregon Health & Science University dedicated to basic research that will lead to new treatments for neurological and psychiatric diseases. Vollum scientists have broad-ranging interests that coalesce around molecular neurobiology and cellular physiology. Their work has transformed the field of neuroscience and, in particular, has provided important advances in the study of synaptic transmission, neuronal development, neurotransmitter transporters, ion channels and the neurobiology of disease.

Mandel lab’s second success in programmable RNA editing leads to a research ‘first’

New ‘proof of principle’ research from the lab of Gail Mandel has demonstrated for the first time that in vivo programmable RNA editing can be used to repair mutations in mouse models of neurological disease. In the study published July 14 in the journal Cell Reports, first author John Sinnamon and collaborators introduced adeno-associated virus bearing Mecp2 guide-targeted editing enzyme or ‘editase’ into the hippocampus of a Rett syndrome mouse model. Research from the team showed that the ‘editase’ repaired approximately half of the mutant Mecp2 RNA and restored MeCP2 protein function across multiple neuronal populations.

Rett syndrome is a neurodevelopmental disorder that is caused by mutations in the gene encoding the X-linked transcription factor methyl CpG binding protein 2, or MECP2, which is critical for normal brain function. Mutations that cause Rett syndrome result in reductions in MeCP2 levels and/or disrupt MeCP2 function.

This is the group’s second success using the site-directed RNA approach and builds on research from 2017 when they successfully repaired mutant Mecp2 mRNA and restored MeCP2 protein function in cultured neurons from a Rett mouse model.

Kevin Wright receives Cure CMD grant to study dystroglycanopathy

Kevin Wright, PhD

Vollum Institute scientist, Kevin Wright, was recently awarded a grant from Cure CMD to study the synaptic defects of dystroglycanopathy in a mouse model.

Dystroglycan is a transmembrane protein that connects the extracellular matrix and the actin cytoskeleton. Defects in Dystroglycan glycosylation lead to a form of congenital muscular dystrophy referred to as dystroglycanopathy. Patients with dystroglycanopathy can display a wide range of nervous system defects. Previous work from many labs, including the Wright lab, has identified critical roles for Dystroglycan in regulating neuronal migration and axon guidance. Recently, it was discovered that Dystroglycan also functions at subsets of synapses in the brain. The Wright lab will use a combination of imaging and electrophysiological approaches in several mouse models of dystroglycanopathy to define the role of dystroglycan in the formation and maintenance of inhibitory synapses in the hippocampus and cerebellum. They will also test whether restoring dystroglycan function is sufficient to rescue synaptic dysfunction in these models. Ultimately, these results will provide insight into the neurodevelopmental deficits in patients with dystroglycanopathies and test whether AAV-based gene therapies have therapeutic potential.

Cure CMD is a non-profit organization founded in 2008 by three parents whose children were affected by Congenital Muscular Dystrophy. Its mission is to find and fund high potential research and clinical trials which could lead to the development of viable therapies to slow, or even stop, the progression of CMDs.

Recognition for our early career awardees

Graduate students and postdoctoral fellows are usually supported by research grants to individual faculty or by institutional training grants from the NIH. However, a sought-after perk for trainees is to obtain an individual fellowship from federal sources or foundations. Such awards are an honor and also provide important financial support for the trainee and their lab. Graduate students and postdoctoral fellows in the Vollum Institute have been remarkably successful in obtaining these awards over the past few years. This is a credit to the quality of the trainees and the support the receive from their mentors. Congratulations to all.

Congratulations to the Neuroscience Graduate Program and Vollum graduate researchers — Sweta Adhikary, Kylie McPherson, Taylor Mighell and Sigrid Noreng — who received 2019 N.L. Tartar Trust Fellowships. The $2,000 grants are awarded annually by the OHSU School of Medicine as a means to support research endeavors and career development. Keep up the great work!

Congratulations to all of our graduate researchers in the Vollum/OHSU Neuroscience Graduate Program who received ARCS Foundation Scholar Awards from the ARCS Oregon Chapter!

First Year: Teva Bracha and Kim Engeln
