The effects of vitamins C, D, E, zinc, selenium and omega-3 fatty acids on the immune system and the possible benefits to those suffering from COVID-19 are presented. These are particularly pertinent in the vulnerable elderly population, who represent a disproportionate burden of morbidity and mortality in these times. All of the nutrients mentioned have […]
Sunlight offers surprise benefit: It energizes infection fighting T cells
Sunlight allows us to make vitamin D, credited with healthier living, but a surprise research finding could reveal another powerful benefit of getting some sun. Georgetown University Medical Center researchers have found that sunlight, through a mechanism separate than vitamin D production, energizes T cells that play a central role in human immunity. Their findings, […]
Mild COVID-19 induces lasting antibody protection, study finds
Months after recovering from mild cases of COVID-19, people still have immune cells in their body pumping out antibodies against the virus that causes COVID-19, according to a study from researchers at Washington University School of Medicine in St. Louis. Such cells could persist for a lifetime, churning out antibodies all the while. The findings, […]
Scientists learn what fuels the ‘natural killers’ of the immune system
Despite a name straight from a Tarantino movie, natural killer (NK) cells are your allies when it comes to fighting infections and cancer. If T cells are like a team of specialist doctors in an emergency room, NK cells are the paramedics: They arrive first on the scene and perform damage control until reinforcements arrive. […]
Scientists uncover SARS-CoV-2-specific T cell immunity in recovered COVID-19 and SARS patients
The study by scientists from Duke-NUS Medical School, in close collaboration with the National University of Singapore (NUS) Yong Loo Lin School of Medicine, Singapore General Hospital (SGH) and National Centre for Infectious Diseases (NCID) was published in Nature. The findings suggest infection and exposure to coronaviruses induces long-lasting memory T cells, which could help in […]
Too much salt weakens the immune system
A high-salt diet is not only bad for one’s blood pressure, but also for the immune system. This is the conclusion of a current study under the leadership of the University Hospital Bonn. Mice fed a high-salt diet were found to suffer from much more severe bacterial infections. Human volunteers who consumed an additional six […]
Mushrooms boost immunity, suggests research
Could a mushroom a day help keep the doctor away? A new University of Florida study shows increased immunity in people who ate a cooked shiitake mushroom every day for four weeks. Of the thousands of mushroom species globally, about 20 are used for culinary purposes. Shiitake mushrooms are native to Asia and are cultivated […]
Zinc helps against infection by tapping brakes in immune response
New research suggests that zinc helps control infections by gently tapping the brakes on the immune response in a way that prevents out-of-control inflammation that can be damaging and even deadly. Scientists determined in human cell culture and animal studies that a protein lures zinc into key cells that are first-responders against infection. The zinc […]
Vitamin D crucial to activating immune defenses
Scientists at the University of Copenhagen have discovered that Vitamin D is crucial to activating our immune defenses and that without sufficient intake of the vitamin, the killer cells of the immune system — T cells — will not be able to react to and fight off serious infections in the body. For T cells […]
Selenium Supplements May Contribute To Reduced HIV Viral Load
Taking daily selenium supplements appears to increase the level of the essential mineral in the blood and may suppress the progression of viral load in patients with HIV infection, according to an article in the January 22 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Advances in antiretroviral therapy (ART) have given […]
