With remarkable similarities to MS, a disease in dogs opens new avenues for study
Microscopic image of cells labeled blue, green, and pink

A naturally occurring canine disease called granulomatous meningoencephalomyelitis replicates many features of multiple sclerosis, including the involvement of B cells (in red) and T cells (green) in the tissues that line the central nervous system. (Image: Penn Vet)

With remarkable similarities to MS, a disease in dogs opens new avenues for study

Researchers at the School of Veterinary Medicine led by Jorge Iván Alvarez and Molly Church found that the canine disease granulomatous meningoencephalomyelitis shares many of the same pathological and immunological features as MS.

Aja Carter and colleagues found that amphibian vertebrae acquired modifications as their habitat shifted from water to land and back. (Pre-pandemic photo)

For early amphibians, a new lifestyle meant a new spine

Moving from water to land and back again corresponded with distinct changes in animals’ spinal morphology, according to a new study led by paleontologist Aja Carter.

Newly described horned dinosaur from New Mexico was the earliest of its kind

With a frilled head and beaked face, Menefeeceratops sealeyi lived 82 million years ago, predating its relative, Triceratops. Researchers including Peter Dodson, of the School of Veterinary Medicine, and Steven Jasinski, who recently earned his doctorate from the School of Arts & Sciences, describe the find.

A genetic condition known as 22q.11.2 deletion syndrome is associated with an increased risk of schizophrenia. A Penn Vet-led team found that a leaky blood-brain barrier, allowing inappropriate immune involvement in the central nervous system, may contribute to this or perhaps other neuropsychiatric conditions. (Image: Courtesy of Jorge Iván Alvarez)

The immune link between a leaky blood-brain barrier and schizophrenia

Research from the School of Veterinary Medicine, Perelman School of Medicine, and Children’s Hospital of Philadelphia points to the involvement of the immune system the brain as a contributor to mental disorders such as schizophrenia.
