Immune system discovery could lead to better spinal injury treatments
by Josh Barney, University of Virginia Credit: Neuron (2023). DOI: 10.1016/j.neuron.2023.04.011 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 findings offer insight into how the immune system responds to spinal-cord injuries, and why that response becomes blunted with the passing years....

Long COVID Seems to Make Distinct Changes to The Immune System
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...

New therapy helps immune system eradicate brain tumors
by Swedish Research Council Graphical abstract. Credit: Cancer Cell (2023). 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...

Common sweetener suppresses mouse immune system — in high doses
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...

New study challenges our understanding of the immune system
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...

How the brain’s immune system worsens epilepsy
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.

Making Tumors Tastier for the Immune System
NOVEMBER 15TH, 2022 CONN HASTINGS MEDICINE, NANOMEDICINE, ONCOLOGY Researchers at The University of Texas MD Anderson Cancer Center have developed a nanotechnology platform that can make cancer cells more vulnerable to immune attack in the body. The researchers call their system the bispecific tumor-transforming nanoconjugate (BiTN) platform. The idea is to make solid tumors more appealing...

Immune system holds clues to patients with high-risk smoldering myeloma likely to benefit from treatment
by Dana-Farber Cancer Institute Graphical abstract. Credit: Cancer Cell (2022). DOI: 10.1016/j.ccell.2022.10.017 For many patients with a condition that often precedes multiple myeloma, early treatment can slow or delay the progression to myeloma. In a new study, investigators at Dana-Farber Cancer Institute demonstrate that changes in immune system cells can indicate which patients with high-risk “smoldering” myeloma...
