Study identifies a new mechanism that explains how immune cells learn to discern friend from foe

The human immune system is a nearly perfect defense mechanism. It protects the body from disease-causing bacteria, viruses, and other pathogens. It detects nascent tumors and eradicates them. It cleans up cellular debris at the site of injury or infection.

Study shines new light on the role of key Parkinson’s disease protein

One of the hallmarks of Parkinson's disease (PD) is the accumulation in the brain of a protein known as alpha-synuclein. For more than two decades, alpha-synuclein has been a focal point of attention for researchers, clinicians and drug makers interested in PD.

University screening programs gave scientists early insights about omicron’s spread

Omicron was first reported in South Africa on Nov. 24, 2021, and within mere days it was already making the rounds in the United States, spiking SARS-CoV-2 case numbers as it infiltrated every school, restaurant, and family gathering. But when exactly did omicron unseat the delta variant to become dominant? And how quickly did it actually take over?

COVID-19 vaccination may offer less effective and shorter-lasting protection for some cancer patients

A study co-led by the Universities of Oxford, Birmingham and Southampton and the UK Health Security Agency (UKHSA), published in Lancet Oncology today by the UK Coronavirus Cancer Evaluation Project, has found that while COVID-19 vaccination is effective in most cancer patients, the level of protection against COVID-19 infection, hospitalization and death offered by the vaccine is less than in the general population and vaccine effectiveness wanes more quickly.

Studies provide insight into how long COVID-19 immunity lasts and nature of immune recall

How does the immune system remember and recognize viral invaders it has encountered in the past? A trio of newly published studies of people infected with SARS-CoV-2, vaccinated against the virus or both, are providing tantalizing new clues about the factors that influence the speed and magnitude of the immune system's response to subsequent infection with variants of SARS-CoV-2.

Researchers reveal the mechanism of action of century-old BCG vaccine

The century-old Bacille Calmette-Guérin (BCG) vaccine against tuberculosis is one of the world's oldest and most widely used vaccines, used to immunize 100 million newborns every year. Given in countries with endemic TB, it has surprisingly been found to protect newborns and young infants against multiple bacterial and viral infections unrelated to TB. There's even some evidence that it can reduce severity of COVID-19.
