OHSU researchers discover a mechanism promoting neural stem cells

A breakthrough study by OHSU scientists demonstrates, for the first time, a mechanism that prevents the formation of new neurons in old brains. The discovery provides a new path for investigation that may lead to the prevention—and potentially the reversal—of age-related dementia by promoting the formation of neurons and preventing their decline. The production of neurons drops dramatically during aging, and the brain slows down. New reports continue to emerge that suggest—but do not prove—that … Read More

Vote by Mar 9 for OHSU Researchers in STAT Madness—inspired by basketball, but all about research

OHSU is in the running for the championship in STAT Madness, a bracketed contest being held to find the best recent innovations in life sciences from the top U.S. research institutions.    OHSU scientist Shoukhrat Mitalipov, Ph.D., submitted his research, which provides key insights into mitochondrial replacement therapy. The field of 32 competitors includes Harvard and Yale, the University of Michigan and Ohio State, and Stanford and UCLA. Each submitted an innovative health or medicine … Read More

OHSU researchers identify gene driving responses to brain injury

In response to brain injury, cells in the nervous system swiftly coordinate events that promote survival and repair. Glial cells—the most abundant cells in the nervous system—quickly locate the trauma site, clear damaged neurons, and recruit extra immune cells. This cascade of glial cells’ reactive events is promoted by Draper, an engulfment receptor needed to recognize and clear cellular debris in fruit flies, roundworms, and mammals. Until recently, the pathways that mediate glia responses to … Read More

OHSU researchers identify structure linked to insulin secretion

It was more than 30 years ago that an ATP-sensitive potassium (KATP ) channel was identified as the key molecular link between glucose metabolism and insulin secretion. The KATP channels sense metabolic changes and translate these energy fluxes into channel gating, which adjusts membrane excitability and regulates insulin secretion. They are the targets of the sulfonylureas, antidiabetic drugs that increase insulin release from beta cells in the pancreas. Genetic mutations of the channel cause several devastating rare … Read More

Vaccine technology developed by OHSU researchers acquired by industry

OHSU researchers made international headlines in 2013 when they published findings that their HIV vaccine not only controlled SIV, the nonhuman primate form of HIV, but cleared it in nearly 60 percent of the monkeys in the trial. The HIV vaccine—developed by of a team of scientists at the OHSU Vaccine and Gene Therapy Institute that includes Jay Nelson, Ph.D.; Klaus Frueh, Ph.D.; Scott Hansen, Ph.D.; and Louis J. Picker, M.D.—has shown such promise in … Read More

OHSU researchers develop new model to study S. mutans behavior at protein level

Breakthrough innovation doesn’t happen overnight, and it doesn’t happen without money. OHSU Core Pilot Grants provide OHSU researchers with funds to develop new concepts or methods and to strengthen extramural grant proposals. The program is made possible by University Shared Resources, the School of Medicine, and the Office of the Senior Vice President for Research. In 2016, the University Shared Resources pilot funds provided more than $200,000 for early research by 22 OHSU researchers. With … Read More

OHSU researchers identify complex required for healthy brain

The intricately orchestrated series of events in nervous system development begins with the formation of neuroepithelial stem cells. These cells proliferate, creating progenitor cells that ultimately form neurons and the glia that provide support and protection for neurons. The balance of neurons and glia is fundamental to the development of a healthy brain. Achieving the optimal neuron–glia balance depends on a delicate relationship between the proliferation of progenitors and the differentiation of neurons and glia. … Read More

OHSU addiction researchers find opportunity for intervention

Patients with substance use disorders often suffer from and are hospitalized due to chronic illnesses that cause medical conditions such as abscesses and cardiovascular disease. Hospitalization temporarily disrupts drug use and can bring patients an increased awareness of mortality, the harmful effects of substance use, and its costs on relationships, including parenting. Some evidence also suggests that initiating medication-assisted treatment during these hospitalizations can increase the likelihood of patients engaging in substance use disorder treatment … Read More

OHSU research yields insight into aspirin’s anti-cancer effect

The anti-inflammatory and anti-platelet properties of aspirin have made it the subject of intensive investigation for over a century. More recently, aspirin use has been correlated with reduced long-term risk of some cancers, particularly colorectal cancer. The reasons remain unknown, as does the degree to which the effect comes from direct inhibition of cancer cells and how much is due to inhibition of platelet activation and function. A study recently completed by a team of OHSU researchers and published in the American … Read More
