Common household chemicals pose new threat to brain health

Research shows chemicals in countless household items harm specialized cells in the brain

A team of researchers from Case Western Reserve University School of Medicine has provided fresh insight into the dangers some common household chemicals pose to brain health. They suggest that chemicals found in a wide range of items, from furniture to hair products, may be linked to neurological diseases like multiple sclerosis and autism spectrum disorders.

Fixing rogue brain cells may hold key to preventing neurodegeneration

Researchers identify new therapeutic approach targeting astrocytes, the brain’s most abundant cells

A team led by scientists at Case Western Reserve University School of Medicine has identified a new therapeutic approach for combating neurodegenerative diseases, offering hope of improved treatments for Alzheimer’s disease, Parkinson’s disease, Vanishing White Matter disease and multiple sclerosis, among others.

5 questions with… Paul Tesar, recipient of the School of Medicine’s highest honor

When Dean Stan Gerson called Paul Tesar to the stage at the School of Medicine’s State of the School address last month, the Dr. Donald and Ruth Weber Goodman Professor of Innovative Therapeutics believed he’d be speaking about the Institute of Glial Sciences—a new center he’s directing. Instead, as his family smiled at him from the back of the auditorium, he made a new discovery: he was receiving the Case Medal for Excellence in Health Science Innovation, the school’s highest possible honor.

Modeling PMD

Our newest paper on modeling Pelizaeus-Merzbacher Disease (PMD) is out today in the American Journal of Human Genetics. Lead author Zach Nevin generated panels of hiPSCs and oligodendrocytes from 12 PMD patients spanning the genetic and clinical diversity of PMD—including point mutations, duplications, triplication, and deletions of PLP1—and developed an in vitro platform for molecular and cellular characterization of all 12 mutations simultaneously. Identification of unique, as well as shared, defects in PLP1 mRNA expression and splicing, OPC development, oligodendrocyte morphology, and myelination from this study will facilitate personalized treatments in the future.
