Repair crews may move in to help fix the oxidative damage in protein factories

In a discovery fundamental to the inner workings of cells, scientists have discovered that if oxidative stress damages protein factories called ribosomes, repair crews may move in to help fix the damage so work can quickly resume.

Researchers develop a backpack-based myeloid cell therapy for MS patients

Multiple sclerosis (MS) is a devastating autoimmune disease that destroys the protective myelin covering around nerves, disrupting communication between the brain and body, and causing patients' ability to move and function to progressively decline.

An extra gene causes excessive inhibitory connections in the neocortex of Down syndrome mouse models

An extra copy of a gene that controls synapse formation in the cortex causes excessive inhibitory signaling and may contribute to Down syndrome, according to a new study publishing April 20th in the open access journal PLOS Biology by Bing Ye of the University of Michigan, US, and colleagues.

Study advances understanding of how melanocyte stem cells work to color hair

Certain stem cells have a unique ability to move between growth compartments in hair follicles, but get stuck as people age and so lose their ability to mature and maintain hair color, a new study shows.

Researchers discover the molecule responsible for guiding T cells toward tumors

Immunotherapy, particularly CAR T-Cell treatment for cancer, is extending the lives of many patients. But sometimes the therapy randomly migrates to places it shouldn't go, tucking into the lungs or other noncancerous tissue and causing toxic side effects.

Latest single cell technology identifies cell types related to CAD pathogenesis

A new study from the University of Eastern Finland identified 12 different cell types involved in the pathogenesis of coronary artery disease, CAD. The researchers also showed that the genetic risk factors for CAD take their effect especially via smooth vascular muscle cells, which change their phenotype as the disease progresses.
