by University of California – San Diego Credit: Unsplash/CC0 Public Domain Inflammasomes make up an intricate system of molecular sensors that our bodies use to sound an alarm when an infection occurs. However, the mechanisms behind these sensors, which initiate responses to threats such as invading pathogens, and how they operate has been an area of...
UNIVERSITY OF VIRGINIA HEALTH SYSTEM New research suggests that the immune system’s ability to respond to spinal cord injuries diminishes with age – and identifies potential avenues to improve that response and help patients heal. The new findings offer important insights into how the immune system responds to spinal-cord injuries, and why that response becomes blunted with the passing...

HEALTH 21 May 2023 By FELICITY NELSON (Oleg Breslavtsev/Getty Images) Long COVID has more than 200 potential symptoms and can affect almost every organ in the body. With more than 65 million people now estimated to live with this often-disabling condition worldwide, and numbers growing daily, there is a desperate need to understand the underlying biology driving it. There are...

DOI: 10.1016/j.ccell.2023.04.010 Researchers from Uppsala University have developed a method that helps immune cells exit from blood vessels into a tumor to kill cancer cells. The goal is to improve treatment of aggressive brain tumors. The study has been published in the journal Cancer Cell. Glioblastoma is an aggressive brain tumor that...
Max Kozlov The research suggests that the biological effects of sucralose — often used as a sugar substitute — go beyond stimulating taste. Credit: Yon Marsh/Alamy High doses of sucralose — a potent, calorie-free sugar substitute that is 600 times sweeter than sucrose — reduce immune responses in mice, a study has found. The researchers...
by Aarhus University Schematic representation of central findings. Left: Polyvalent antigen induces robust activation at both low and high stoichiometry, whereas monovalent antigen is only active at high stoichiometry, and small-molecule or small footprint monovalent antigen has no activity whatsoever. Right: The role of footprint in determining monovalent antigen activity. There is not a simple...

by Richard C. Lewis, University of Iowa University of Iowa biologists have definitively linked the brain’s immune system to epilepsy. The caption shows the sequence of events that triggers worsened seizures in fruit flies, which follow a similar pattern in humans. The findings could lead to more effective drugs to treat epilepsy.
