When people recover from infection with a virus, the immune system retains a memory of it. Immune cells and proteins that circulate in the body can recognize and kill the pathogen if it’s encountered again, protecting against disease and reducing illness severity. This long-term immune protection involves several components. Antibodies—proteins that circulate in the blood—recognize… Continue reading What Happens after COVID-19?

A Better Weapon in The Fight against Cancer
Johns Hopkins researchers have invented a new class of cancer immunotherapy drugs that are more effective than existing methods at harnessing the immune system’s power to fight cancer. This new approach, reported in Nature Communications, results in a significant decrease of tumor growth, even against cancers that do not respond to existing immunotherapy. “The immune… Continue reading A Better Weapon in The Fight against Cancer
A New Weapon Against Immune-System Diseases?
Anti-aging proteins are noted for protecting against cancer, neurodegeneration, and cardiovascular disease. One protein may also be beneficial to the immune system, new research shows. The protein in question is called SIRT1, more commonly known for being activated by red wine. In the new study, published in the Journal of Experimental Medicine, scientists from the… Continue reading A New Weapon Against Immune-System Diseases?
Study Upends Long-Held Belief About “Self-Reactive” Immune Cells
Decades’ worth of textbook precepts about how our immune systems manage to avoid attacking our own tissues may be wrong, according to researchers at the Stanford University Medical Center. The study was published in May 2015 in the journal Immunity. A release from Stanford reports that the results contradict a long-held belief that self-reactive immune… Continue reading Study Upends Long-Held Belief About “Self-Reactive” Immune Cells
Could Type 2 Diabetes Ever Be Reversed?
Blocking inflammation in fat tissue may hold the key to preventing or even reversing type 2 diabetes, new research has found. Australian and Japanese researchers made the discovery, which was reported in the journal Nature Immunology. The researchers discovered that immune cells called regulatory T cells (Tregs), are crucial in controlling inflammation in fat tissue and… Continue reading Could Type 2 Diabetes Ever Be Reversed?
