When a new memory forms the brain undergoes physical and functional changes known collectively as a “memory trace.” This memory trace represents the specific patterns of neuronal activity and ...

A team of researchers has discovered that the memory of the immune system relies on characteristic epigenetic features and a specific 3D arrangement of the DNA in the nucleus of memory cells, allowing ...

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 ...

Scientists at UW Medicine, University of Washington, and their collaborators have pinpointed exactly when cytotoxic T lymphocytes form memories during infection. They also examined the epigenetic ...

The immune system is an incredibly complex network that has some amazing capabilities. It can eliminate dangerous cells that may lead to cancer, and defend the body against a wide variety of ...

Neuroinflammation, a prolonged activation of the brain's immune system prompted by infections or other factors, has been linked to the disruption of normal mental functions. Past studies, for instance ...

It’s been 16 years since scientists first coaxed skin cells back into their embryonic state, a development that made it possible to sidestep the thorny ethical dilemmas around sourcing human stem ...

An analysis of the Framingham Heart Study data found that higher epigenetic aging metrics predicted lower scores on the digital Clock Drawing Test 7 years later. The strongest association was with ...

Obesity rates are increasing in the United States and around the world, and the condition has been linked to increases in the risks of a wide range of health disorders, including diabetes and ...

The immune system is one of the most complex parts of our body. It keeps us healthy by getting rid of parasites, viruses or bacteria, and by destroying damaged or cancer cells. One of its most ...
