A new study investigated food preservatives and the immune system. Irina Marwan/Getty Images A recent study has assessed the harmful effects of chemical food additives and food contact substances on the immune system. The study compared laboratory toxicology testing (ToxCast) results with data from previous animal tests and epidemiological Trusted Sourcestudies. The ToxCast results and available animal...
H. LEE MOFFITT CANCER CENTER & RESEARCH INSTITUTE TAMPA, Fla. (April 8, 2021) — A dysfunctional immune system significantly contributes to the development of cancer. Several therapeutic strategies to activate the immune system to target cancer cells have been approved to treat different types of cancer, including melanoma. However, some patients do not show beneficial clinical responses...
ENVIRONMENTAL WORKING GROUP WASHINGTON – A food preservative used to prolong the shelf life of Pop-Tarts, Rice Krispies Treats, Cheez-Its and almost 1,250 other popular processed foods may harm the immune system, according to a new peer-reviewed study by Environmental Working Group. For the study, published this week in the International Journal of Environmental Research and...

Agents that prevent immune escape are attractive targets for the development of new cancer therapies. Scientists led by Prof. Herbert Waldmann and...

by The Scripps Research Institute A computer image of HIV’s outermost layer, densely coated with sugar molecules (purple) that do not trigger an immune response. Most of the surface not covered in sugars (in red and yellow) is highly variable, making it difficult for the immune system to generate antibodies capable of neutralizing the virus.

by Washington University School of Medicine mmune cells (yellow and purple) fill a sinus (teal) in the outer layer of the meninges, the tissue that surrounds the brain and spinal cord. Researchers at Washington University School of Medicine in St. Louis have found that immune cells stationed in such sinuses monitor the brain and initiate an immune response...
by Lisbeth Heilesen, Aarhus University Researchers from Aarhus University have discovered that ITIH4 inhibits proteases in the innate immune system via an unknown mechanism. Credit: Rasmus Kjeldsen Jensen. Although the protein ITIH4 is found in large amounts in the blood, its function has so far been unknown. By combining many different techniques, researchers from Aarhus University have discovered that...
RUSH UNIVERSITY MEDICAL CENTER A new therapy developed by researchers at Rush University Medical Center is showing success as a way to prevent COVID-19 symptoms in mice. In a study published in the Journal of Neuroimmune Pharmacology, mouse models with COVID-19 showed positive results when a small peptide was introduced nasally. The peptide proved effective in reducing fever, protecting...
As the number of people who have fought off SARS-CoV-2 climbs ever higher, a critical question has grown in importance: How long will their immunity to the novel coronavirus last? A new Rockefeller study offers an encouraging answer, suggesting that those who recover from COVID-19 are protected against the virus for at least six months,...
