Researchers at the University of Cologne and University Hospital Cologne have determined that the novel mRNA-based COVID-19 vaccines not only induce acquired immune responses such as antibody production, but also cause persistent epigenetic changes in innate immune cells.

The study, “Persistent epigenetic memory of SARS-CoV-2 mRNA vaccination in monocyte-derived macrophages,” led by Professor Dr. Jan Rybniker, who heads the Division of Infectious Diseases at University Hospital Cologne and is a principal investigator at the Center for Molecular Medicine Cologne (CMMC), and Dr...

Researchers from the University of Colorado Cancer Center have solved a cellular mystery that may lead to better therapies for colorectal and other types of cancer.

Peter Dempsey, Ph.D., professor of pediatrics–developmental biology in the CU School of Medicine, and Justin Brumbaugh, Ph.D., assistant professor of molecular, cellular, and developmental biology at CU Boulder, recently published a paper in the journal Nature Cell Biology showing the importance of the H3K36 methylation process in regulating plasticity and regeneration in intestinal cells.

“The intestine has an enormous ability to regenerate itself after injury, an...

A stem cell treatment helped improve the motor function of two out of four patients with a spinal cord injury in the first clinical study of its kind, Japanese scientists said.

There is currently no effective treatment for paralysis caused by serious spinal cord injuries, which affect more than 150,000 patients in Japan alone, with 5,000 new cases each year.

Researchers at Tokyo’s Keio University are conducting their study using induced pluripotent stem cells (iPS)—created by stimulating mature, already specialized, cells back into a juvenile state.

They can then be prompted to mature into different kinds of cells, with the Keio researchers using iPS-derived cells of the neural stem.

The university said on Friday that the motor function s...
