Despite progress, health disparities remain among racial and ethnic minority groups post-ACA

2017_0911_heather_angier_midIn a first-of-its-kind study, researchers from OHSU and OCHIN report that community health centers in states that expanded Medicaid coverage experienced a decrease in uninsured visits and an increase in Medicaid-insured visits compared with non-expansion states. The research, published in the Annals of Family Medicine. also found that Hispanic patients have the highest rates of uninsured clinic visits, both before and after Affordable Care Act expansion.

Motor neurons aren’t the only site for restoring locomotive function

TBPH mutant larvae show defective motor behavior, which can be rescued by 654 cacophony expression in selected neurons.

TBPH mutant larvae show defective motor behavior, which can be rescued by 654 cacophony expression in selected neurons.

Amyotrophic lateral sclerosis is the most common adult onset motor neuron disease for which there is no cure or treatment that significantly extends life. ALS causes the death of neurons that control voluntary muscles and is characterized by gradually worsening weakness, loss of motor function and, when the individual can no longer breathe, death. The only FDA-approved drug used to treat ALS prolongs on average the lifetime of a patient by two to three months.

A feature in neurodegenerative diseases, including about 90 percent of patients with ALS, is a mutation in the transactivating responsive sequence DNA-binding protein (TDP-43). Neurons are known to be sensitive to TDP-43 expression levels, but the specific defects caused by TDP-43 loss of function have not been described in detail.

Now, in a paper published in the Journal of Neuroscience, a team led by David Morton, Ph.D., has demonstrated that function can be restored by increased expression of a single gene in two central neurons. Conducted in the lab of Morton, professor of integrative biosciences and associate dean of research in the School of Dentistry, the research expanded on Morton’s 2013 discovery that expression of a voltage gated calcium channel restored the loss of motor function in a fruit fly model of ALS.

The team hypothesized that the mechanisms by which TDP-43 expression restores motor function would take place in motor neurons. Kayly Lembke, lead author and graduate student in the Department of Physiology and Pharmacology, found that, in addition to motor neurons, expression of a voltage gated calcium channel in two central neurons in the brain are able to restore motor defects.

The finding that such a small number of neurons—two—can restore motor function is significant. TDP-43 regulates a large number of other genes and, if restoration required a significant number of processes, it would be extremely challenging to target any one of the processes. The discovery that expressing this channel can restore function opens the future possibility of therapeutic strategies that target this channel. This possibility, however, will require substantially more work.

The next step is developing a more targeted model.

When and how to request an urgent IRB review

Submissions for IRB review are typically reviewed in the order in which they are received. However, there are situations that require more urgent attention.

 Examples of these are:

  • Subjects are critically ill and awaiting IRB approval of an initial submission or modification.
  • Imminent funding deadline (e.g., NIH just-in-time notifications).
  • Projects with tight timelines, such as a summer student research project.

In urgent cases, please take the following steps:

  1. Ensure your submission is complete and accurate to avoid the delay in having it returned to you for corrections.
  2. Prepare and submit the project as quickly as possible.
  3. Use the ‘Add Comment’ function in the eIRB to request an urgent review and route to the “IRB Coordinator” by marking that checkbox before submitting your comment. 
  4. Email the IRB at to inform their office of your request, indicating in the subject line that it is an urgent review request.  If possible, include the IRB number with a hyperlink in the body of the email and describe the rationale for the request.

New findings show retinal development requires the protein dystroglycan

Dystroglycan is required to localize ECM proteins at the ILM.

Dystroglycan is required to localize ECM proteins at the ILM.

OHSU scientists have published a paper that provides new information on retinal development and visual system abnormalities present in dystroglycanopathy, a form of muscular dystrophy that results from defective function of the protein dystroglycan.

Patients with severe forms of dystroglycanopathy frequently experience visual system problems in addition to other neurodevelopmental abnormalities. There is some understanding of dystroglycan’s influence on brain development, but its role in regulating retinal development has remained poorly understood. A team led by Kevin Wright, Ph.D., an assistant professor at the Vollum Institute, has published findings in the Journal of Neuroscience that provide new insight into the mechanisms of dystroglycan function in the retina using a mouse model of dystroglycanopathy.

Reena Clements, a neuroscience graduate student in the Wright lab, demonstrated that dystroglycan is required for maintaining the structural integrity of the inner limiting membrane in the developing retina. The team found that in the absence of functional dystroglycan, this membrane, which separates the retina from the vitreous, begins to degenerate. Breaches that form in the membrane allow neurons to migrate into the vitreous space, disrupting the highly organized structure of the retina.

These results demonstrate that disorganization of retinal circuit development is a likely contributor to visual dysfunction in patients with dystroglycanopathy. The findings in the eye are similar to what previously has been seen in the brain, suggesting a critical role for dystroglycan that is conserved throughout the developing nervous system.


In addition to Wright and Clements, coauthors include Rolf Turk, Ph.D., and Kevin P. Campbell, Ph.D.
