A massive international study could upend 40 years of heart attack treatment. Researchers found that beta blockers—routinely prescribed after uncomplicated heart attacks—offered no real benefit for patients whose heart function remained normal, despite…
A study led by researchers at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) has identified a mitochondrial checkpoint that enables dendritic cells to efficiently activate T lymphocytes against viruses and tumors. Dendritic cells are im…
Not all broken genes fail in the same way: some simply stop working, while others interfere with what still works. Researchers from Hiroshima University have identified a critical boundary within the immune-regulating gene called RELA that helps predic…
In a new study published in Nature Immunology, researchers at Boston Children’s Hospital demonstrated that pairing the original COVID-19 mRNA vaccine with an immune system enhancer, known as an adjuvant, improved the duration of the vaccine’s protectio…
Immunotherapy for cancer works like a guided missile, directing the body’s immune cells toward tumor cells. However, not all immune cells respond to the call to attack, and this can lead to variability in treatment responses. As immune cell response is…
Scientists at the Garvan Institute of Medical Research have captured, for the first time, “housekeeping” immune cells actively attacking and engulfing live melanoma cells—a discovery that could change the way we approach treatment for one of Australia’…
Researchers at The George Washington University, working with Weill Cornell Medicine, have identified specific gut bacteria linked to better responses to cancer immunotherapy in patients with advanced melanoma. The study analyzed data from 678 patients…
Scientists at La Jolla Institute for Immunology (LJI) have discovered that combining key vaccine ingredients could give the body the tools it needs to fight the entire family of arenaviruses with a single vaccine. This “pan-arenavirus” vaccine approach…
MIT scientists have identified cysteine — an amino acid found in foods like meat, dairy, beans, and nuts — as a potent trigger for intestinal repair. In mice, a cysteine-rich diet activated immune cells that released healing signals, helping stem cells…
A newly developed microscopy technique allows, for the first time, the visualization of more than 30 protein markers simultaneously in the human brain and uses bioinformatics to analyze their spatial relationships. In the process, the researchers have …
