Brain's immune cells put the brakes on out-of-control circuits in mouse model of Alzheimer
Researchers at Trinity College Dublin have discovered that microglia—the main immune cells of the brain—play a critical role in maintaining the stability of neuronal networks in Alzheimer's disease. Crucially, this suggests treatments that indiscriminately suppress these cells co
Best treatment for multiple sclerosis may be antivirals
Best treatment for multiple sclerosis may be antivirals
Low levels of replicating Epstein-Barr viruses might be the main driver of the autoimmune condition multiple sclerosis. This may mean that targeting them would be as effective as suppressing the immune system, with fewer side effects
The hidden skeleton “gatekeeper” inside brain cells could help fight Alzheimer's
The hidden skeleton “gatekeeper” inside brain cells could help fight Alzheimer's
Researchers have discovered that a microscopic skeleton inside neurons does much more than hold cells together. It acts as a gatekeeper that controls what brain cells absorb and when they absorb it. When this protective structure weakens, neurons rapidly take in harmful proteins
Scientists find hidden individuality in viral infections
Scientists find hidden individuality in viral infections
An international team of researchers developed a new way to uncover hidden differences in how viruses infect and destroy individual microbial cells—solving a biological puzzle that has persisted for more than 80 years.

‘Like working in a kettle’: France’s overcrowded prisons swelter under historic heatwave
The deadly heatwave sweeping France has once again exposed the structural problems of the country’s chronically overcrowded prisons, with groups of three or four detainees crammed into airless cells built to hold a lone prisoner. Analysts and prison staff alike have criticised a
Immune ecotypes may explain multiple myeloma outcomes missed by disease staging
Immune ecotypes may explain multiple myeloma outcomes missed by disease staging
Researchers at The University of Texas MD Anderson Cancer Center have created a comprehensive single-cell map of the tumor immune microenvironment in multiple myeloma and its precursor conditions. The study provided insights that may explain why patients with similar diagnoses of

Stem cell science unlocks more mysteries of the menstrual cycle
Amid all the advances in modern medicine, much of the science behind a woman's menstrual cycle remains mysterious, so a team at Hudson Institute of Medical Research is aiming to change that. Professor Caroline Gargett is an expert in the human endometrium, the highly regenerative
The skin microbiota—billions of microbes that protect or harm
A constant interplay takes place on the surface of the body between cells, the immune system and the skin microbiota. We do not notice it—until the balance is disturbed. Then it becomes clear that the outermost layer of the skin plays a crucial role in the well-being of the whole
