Herd immunity an impractical strategy, study finds
Achieving herd immunity to COVID-19 is an impractical public health strategy, according to a new model developed by University of Georgia scientists. The study recently appeared in Proceedings of the National Academy of Sciences.
Study takes us a step closer to a universal antibody test for COVID-19
A study released by Houston Methodist Sept. 10 in the Journal of Clinical Investigation takes researchers closer to developing a uniform, universal COVID-19 antibody test. The multicenter collaboration tested alternative ways to measure COVID-19 antibody levels that’s faster, easier and can inexpensively be used on a larger scale to accurately identify potential donors for plasma therapy with the best chance of helping patients infected with SARS-CoV-2.
Pregnant mother’s immunity tied to behavioral, emotional challenges for kids with autism
Children with autism born to mothers who had immune conditions during their pregnancy are more likely to have behavioral and emotional problems, a UC Davis Health study has found. Offspring sex may also interact with maternal immune conditions to influence outcomes, particularly in terms of a child’s cognition.
Mount Sinai Researchers Discover Treatment Option for Rare Genetic Disorder
Researchers from the Icahn School of Medicine used a novel genetic sequencing technology to identify the genetic cause of—and a treatment for—a previously unknown severe auto inflammatory syndrome affecting an 18-year-old girl since infancy.
Coronavirus antibodies fall dramatically in first 3 months after mild cases of COVID-19
A study by UCLA researchers shows that in people with mild cases of COVID-19, antibodies against SARS-CoV-2 — the virus that causes the disease — drop sharply over the first three months after infection, decreasing by roughly half every 73 days. If sustained at that rate, the antibodies would disappear within about a year.
Eye Injury Sets Immune Cells On Surveillance To Protect The Lens
The discovery further challenges the accepted scientific dogma that the lens is shut out from the immune protection.
Nutrition Researchers Say There is Nothing to Eat to Protect Against Covid-19
Global ILSI organized a science webinar with experts from the U.K. on nutrition and immunity.
University of Kentucky Researchers Leading Study of COVID-19 Immunity
University of Kentucky researchers have launched antibody testing that will help to understand what immunity to COVID-19 really means.
New University of Kentucky study could change what we know about platelets
The $6.6 million study will focus on how platelets function when they form clots in blood vessels and when they sense circulating pathogens, like viruses.
Webinar: COVID-19, Nutrition in Immune Response Against Viral Infection
ILSI hosts a free public webinar on COVID-19, nutrition and immune response.
Impaired Immunity, Gene Expression May Explain Higher COVID-19 Risk in People with Diabetes
The behavior of previous coronaviruses together with physiological characteristics of diabetes may help explain why people with diabetes have a higher risk of developing COVID-19, a respiratory disease caused by the novel coronavirus SARS-CoV-2.
Ending the Pandemic
As scientists forge ahead to piece together a comprehensive profile of the new coronavirus fueling a historic pandemic, they are focusing their efforts on six areas: epidemiology, diagnostics, pathogenesis, clinical disease management, treatment and vaccines.
Learning from the Recovered
Researchers at Harvard Medical School and at Brigham and Women’s Hospital are adapting an antibody-detection tool to study the aftermath of infections by the novel coronavirus that is causing the current global pandemic.
Scientists May Have a Way to Let Preemies Breathe Easier
The continuing epidemic of pre-term birth includes this stark reality: tiny, fragile babies are born with underdeveloped lungs and prone to lifelong respiratory infections and related chronic illnesses. Cincinnati Children’s researchers report in Immunology the discovery of a complex biological process could in the development of cost effective treatments to help babies develop lifelong pulmonary resistance to respiratory infections.
Brain links to embryonic immunity, guiding response of the “troops” that battle infection
Researchers have discovered that the brains of developing embryos provide signals to a nascent immune system that help it ward off infections and significantly improve the embryo’s ability to survive a bacterial challenge. Viable brainless frog embryos can survive for some time, but exhibit chaotic and ineffective responses.
Study results will inform immunization programs globally
The results of the B Part of It study – the largest meningococcal B herd immunity study ever conducted – are published today in the New England Journal of Medicine.
A MOTHER’S BUGS
-Newborn mice derive protective antibodies from their mothers’ microbiota
-Antibodies derived from mothers’ microbiota ward off both localized and widespread systemic infections by the bacterium E. coli
-Study points to the role of maternal microbes in offspring protection and neonatal immunity
-Findings can inform development of microbe-based therapies against infectious diarrhea in infants
MORE THAN A WATCHDOG
Study in mice shows the nervous system not only detects the presence of Salmonella in the gut but actively stops the organism from infecting the body
Nerves in the gut prevent Salmonella infection by shutting the cellular gates that allow bacteria to invade the intestine and spread beyond it
As a second line of defense, gut neurons help avert Salmonella invasion by maintaining the levels of key protective microbes in the gut
Findings reveal prominent role for nervous system in infection protection and regulation of immunity
Researchers Find Common Measures of Immune Status, Inflammation Can Predict Mortality
News release about a new collaborative study led by Cleveland Clinic and University Hospitals finding that commonly used clinical indicators of immune status and inflammation can predict mortality in the general population.
HOW MEASLES WIPES OUT THE BODY’S IMMUNE MEMORY
Study shows measles wipes out 20 to 50 percent of antibodies against an array of viruses and bacteria, depleting a child’s previous immunity
Measles-ravaged immune system must “relearn” how to protect the body against infections
Study details mechanism and scope of this measles-induced “immune amnesia”
Findings underscore importance of measles vaccination, suggesting those infected with measles may benefit from booster shots of all previous childhood vaccines
Creatine powers T cells’ fight against cancer
The study, conducted in mice, is the first to show that creatine uptake is critical to the anti-tumor activities of killer T cells, the foot soldiers of the immune system.
Harvard Medical School Announces Media Fellows for Second Thematic Track of 2019
Harvard Medical School has selected the 2019 media fellows for the second of its two thematic tracks this year: Immunity and Inflammation: A friend, a foe (Nov. 4-8).
Gut Immunity More Developed Before Birth Than Previously Thought
The first comprehensive look at the immune system of the fetal gut shows that it is far more developed before birth, and could help develop new maternal vaccines and understand if we are predisposed to autoimmune diseases before birth.
Blocking a Hormone’s Action in Immune Cells May Reduce Heart Disease Risk
Blocking the mineralocorticoid receptor (MR)—a protein that helps maintain normal levels of salt and water in the body—in immune cells may help reduce the risk of heart attack and stroke by improving blood vessel health. The study will be presented today at the American Physiological Society (APS) Aldosterone and ENaC in Health and Disease: The Kidney and Beyond Conference in Estes Park, Colo.
Baking Soda Boosts Immunity, Impairs Insulin Response in Type 2 Diabetes
Researchers learn insulin response connected to alkaline load, not inflammation Charlottesville, Va. (June 24, 2019)—Early research suggests that the common pantry staple baking soda affects inflammation and insulin handling in type 2 diabetes. The findings will be presented today at…
