Written by Lindsey DeSoto, RDN, LD on February 2, 2022 — Fact checked by Hannah FlynnThis series of Special Features takes an in-depth look at the science behind some of the most debated nutrition-related topics, weighing in on the facts and debunking the myths. Design by Diego Sabogal The immune system is a large network of cells, organs, and proteins. It...
Clues suggest anti-inflammatory macrophages are different in people with diabetes. The link between obesity and illness, particularly type 2 diabetes, is well known. Yet researchers are actively working to understand what it is about fat tissue that leads to metabolic disease. Studies in mice have shown that an increase in immune cells called macrophages in fat tissue...

Credit: DOI: 10.1016/j.celrep.2021.110111 Awakening the immune system’s instinct for destroying cancer, using two molecules located on the surface of macrophages: that’s the promising avenue opening up from recent laboratory work of Dr. André Veillette. Director of the Molecular Oncology Research Unit of the Montreal Clinical Research Institute (IRCM) and...
by Alan Mozes Meditation done at an intense level may bring a significant boost to the inner workings of your immune system. The finding follows a blood sample analysis that took pre- and post-meditation snapshots of genetic activity among more than 100 men and women. That analysis suggested that meditation boosted the activity of hundreds of genes...
MAYO CLINIC ROCHESTER, Minn. ― Adding messenger RNA, or mRNA therapy improves the response to cancer immunotherapy in patients who weren’t responding to the treatment, Mayo Clinic research shows. Immunotherapy uses the body’s immune system to prevent, control, and eliminate cancer. The study is published in Cancer Immunology Research, a journal of the American Association...
