Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in ...
Researchers at the University of Arizona have uncovered a previously unknown population of circulating immune cells that play a critical role in fibrosis, the buildup of scar tissue that can lead to ...
Cell signaling is crucial for cells to communicate and function correctly. Disruptions in these pathways, caused by genetic mutations or environmental factors, can lead to uncontrolled cell growth, ...
Innate immune sensors—known as pattern recognition receptors (PRRs)—detect specific molecular components of bacterial or ...
Cancer begins when mutations in specific genes override the body’s built-in controls on cell division, allowing rogue cells ...
