Modeling the most common form of vision loss in older adults
Older man has eye examined

As the population ages, cases of age-related macular degeneration are forecast to skyrocket. New research led by a team from Penn may help make inroads into understanding its roots and possible therapies.

Modeling the most common form of vision loss in older adults

Age-related macular degeneration is the leading cause of vision loss in people older than 50. Kathleen Boesze-Battaglia and colleagues have developed a model system that mimics many features of the human condition, giving scientists a platform to gain a deeper understanding of risk factors and possible treatments.

To resolve inflammation, location matters
A diagram explains the action of the protein Del-1 and macrophages

Researchers from Penn and Technical University of Dresden found that the protein Del-1 takes on different functions depending on the cell that secretes it. When secreted by the immune system's macrophages, it acts as a bridge between those cells and neutrophils to help clear inflammation. (Image: Courtesy of George Hajishengallis)

To resolve inflammation, location matters

A single protein can both restrain the initiation of inflammation and help to actively resolve it, according to new research led by George Hajishengallis of the School of Dental Medicine. He and his colleague found that the type of cell that secretes the protein determines which activity the protein promotes.

Drivers of inflammation provide valuable targets for new gum disease therapies

A subset of T cells contributes to the inflammation and bone loss that characterizes periodontitis, a severe form of gum disease. According to new research by George Hajishengallis and scientists at the National Institutes of Health, drugs that specifically inhibit these cells may offer an effective therapy.

Targeting a viral vulnerability to treat disease

Robert Ricciardi company ViRAZE utilizes interdisciplinary approaches to drug discovery. Its first target is molluscum contagiosum, a disease that targets children and immune-compromised adults with no current FDA-approved therapy.

Regrowing dental tissue with stem cells from baby teeth
Shi dental pulp

Stem cells extracted from baby teeth were able to regenerate dental pulp (above, with fluorescent labeling) in young patients who had injured one of their adult teeth.

Regrowing dental tissue with stem cells from baby teeth

In a clinical trial led by Songtao Shi of the School of Dental Medicine, stem cells extracted from baby teeth were used to regrow the living tissue in teeth damaged by injury. The promising findings highlight the potential of dental stem cells, which could be used in a wide range of dental procedures, or treating certain systemic diseases.

Dental plaque is no match for catalytic nanoparticles
Koo ferumoxytol treatment

Treatment with a nanoparticle and hydrogen peroxide (right panel) left little in the way of bacteria (in blue) or the sticky biofilm matrix (in red), making the combination a potent force against dental plaque.

Dental plaque is no match for catalytic nanoparticles

A recent study found that nanoparticles can break down dental plaque with nanoparticles that target biofilms, preventing tooth decay in humans and animal models without damaging surrounding oral tissue.
