Medical Xpress / Scientists uncover key 'lipid transporter' that keeps skin healthy
Scientists have identified the transporter protein that allows essential fats in the bloodstream to enter the skin, reshaping understanding of how the skin maintains its protective barrier.
Medical Xpress / Protein atlas connects the biological dots underlying neurodegenerative diseases
Neurodegenerative diseases form a tangled biological web with overlapping molecular signatures and symptoms. To decode this complexity, a multi-institute collaboration led by St. Jude Children's Research Hospital scientists ...
Medical Xpress / Changes in protein production linked to autism-like behavior in mice
Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by differences in how people interact or communicate with others, as well as restricted interests and repetitive patterns of behavior. Past studies ...
