Red blood cells carry oxygen from the lungs to every other organ, and blood-forming stem cells must make about 200 billion new red blood cells each day to keep the oxygen flowing. For many years, ...

A group of immune proteins called the inflammasome can help prevent blood stem cells from becoming malignant by removing certain receptors from their surfaces and blocking cancer gene activity, ...

Aging is defined as the deterioration of function over time, and it is one of the main risk factors for numerous chronic diseases. Although aging is a complex phenomenon affecting the whole organism, ...

The immune system consists of inflammatory and regulatory T cells (Tregs) that promote or dampen immune activity, respectively. These cells react to specific antigens that specialized cells like ...

A groundbreaking new treatment using genome-edited immune cells, developed by scientists at UCL (University College London) and Great Ormond Street Hospital (GOSH), has shown promising results in ...

Blood usually falls into a few widely recognized categories or types, based on the proteins that are expressed on the surface of red blood cells. For example, A or B antigens may be present there, ...

During fasting or exercise, immune cells (red) migrate to the pancreas and stimulate glucagon-producing cells (orange) to regulate blood sugar, with cell nuclei shown in blue. “For decades, immunology ...

New research by scientists at the Champalimaud Foundation has revealed a surprising new role for the immune system. Their study in mice found that during periods of low energy— such as intermittent ...
