DOI: 10.1016/j.cell.2022.11.031 If B cells are the munitions factories of the immune system, manufacturing antibodies to neutralize harmful pathogens, then the tiny biological structures known as germinal centers are its weapons-development facilities. Formed in response to infection and vaccination, these microscopic training grounds allow B cells to perfect the...

by Marie-Morgane Le Moel with Daniel Lawler in Paris The cells of an “artificial skin” being developed by French company Urgo. Far from the humble sticking plaster, medical firms and researchers are seeking to create the “ultimate dressing”—artificial skin they hope will revolutionize the treatment of severe burns. For the last 18 months, researchers from the French firm Urgo...
by UT Southwestern Medical Center Credit: Pixabay/CC0 Public Domain UT Southwestern researchers have identified the molecular function of 87 inherited genetic variants that affect the risk of prostate cancer, and the majority appear to control the activity of genes located far away from the risk variants themselves. The findings, published in Cancer Discovery, could lead to better ways...
A new study investigates calorie restriction in humans. Catherine MacBride/Stocksy Laboratory studies have found that some animals on calorie-restricted diets live longer. Researchers are keen to find out whether there is a similar effect in people. Now, a small-scale study suggests that moderate calorie restriction may benefit human health. The researchers identified a key protein that might increase...
Walnuts are a rich source of magnesium. simonkr/Getty Images Magnesium deficiency has links to a wide range of diseases. Researchers have now shown in mice how magnesium improves the ability of the immune system to eliminate infected and cancerous cells. Their analysis of data from clinical studies also suggests that low serum levels of the substance...

by Bruno Geoffroy, University of Montreal Hospital Research Centre Neuroprotection mechanism of Lacticaseibacillus rhamnosus HA-114. ALS models have impaired carnitine shuttle, a mechanism to transport long chain fatty acids across the mitochondrial membrane for energy production via β-oxidation. Fatty acids, supplied by the probiotic bacteria, is believed to enter the mitochondria independently of the carnitine...
