Combining low-dose radiotherapy with immunotherapy eradicates metastatic cancer in mice

More doesn’t necessarily mean better — including in cancer treatment. University of Wisconsin–Madison and University of Pittsburgh School of Medicine scientists report today in the journal Science Translational Medicine that combining targeted radiopharmaceutical therapy with immunotherapy significantly boosts eradication of metastatic cancer in mice, even when the radiation is given […]

Chronic Inflammation Negatively Impacts Proteostasis in Aging Tissues

Proteostasis describes the steady state of a cell, maintaining an appropriate balance of various forms of protein machinery in order to enable continued normal function. With advancing age, proteostasis becomes disrupted in numerous complicated ways. This is a downstream outcome of underlying molecular damage, the reactions to that damage, and […]

Getting to the Heart of Genetic Cardiovascular Diseases: How One Penn Researcher is Using Her Expertise to Help Patients Lead More Active Lives

When she isn’t pursuing her favorite heart-pumping activities of running, swimming, or cycling, Sharlene M. Day, MD, a Presidential Associate Professor of Cardiovascular Medicine and director of Translational Research for the Penn Cardiovascular Institute, is focused on the heart in another way; trying to unlock and treat the mysteries of genetic […]

Ferroptosis in Aging

Ferroptosis is a mode of programmed cell death that manages to be both fairly well explored in the broader research community and far less visible than other programmed cell death processes. It was first named and described about a decade ago, though of course researchers have long explored aspects of […]

A Breakthrough in Photodynamic therapy

An international team led by physics researchers at The University of Texas at Arlington has published a paper in the high-impact journal Bioactive Materials that describes a breakthrough method of photodynamic therapy (PDT), an emerging cancer treatment. Nil Kanatha Pandey, a doctoral student in physics Professor Wei Chen’s lab, is the first […]

Memory-making involves extensive DNA breaking

The urgency to remember a dangerous experience requires the brain to make a series of potentially dangerous moves: Neurons and other brain cells snap open their DNA in numerous locations — more than previously realized, according to a new study — to provide quick access to genetic instructions for the mechanisms […]

Breakthrough into leading cause of blindness

A University of Manchester led a team of scientists has discovered that the most common form of adult blindness is probably caused by a failure of at least one of five proteins to regulate the immune system. The breakthrough could one day herald the development of transformative treatments for developing […]

Using “guilt by association” to classify cells

Biologists are trying to figure out what makes a cell unique in form and function. But they are not certain which components are key to making similar cells behave differently. Cold Spring Harbor Laboratory (CSHL) Associate Professor Jesse Gillis and his lab are tackling this problem with a new statistical method: they […]

Preventing lung cancer’s unwelcome return

When a doctor gives a patient antibiotics for a bacterial infection, they usually require them to finish the entire treatment, even when symptoms go away. This is to ensure the drugs kill off any remaining bacteria. Cold Spring Harbor Laboratory (CSHL) Visiting Scientist Raffaella Sordella investigated a similar problem that occurs in […]

A system for the early detection of tumour cells has been developed

Altum Sequencing, a start-up in the biotechnology sector that is part of the Universidad Carlos III de Madrid’s (UC3M) Incubation and Acceleration of Companies and Industrial PhD programmes, has patented a system that allows for the early identification of tumour-specific genetic markers and the quantification of cancer cells following responses […]

COVID-19 vaccine antibodies weaker vs. Delta/Kappa viral variants

Antibodies induced by currently available mRNA vaccines can still neutralize the Delta and Kappa variants of the SARS-CoV-2 virus, but do so at a reduced potency, according to a report published in the New England Journal of Medicine. The Delta variant, first identified in India and previously known as B.1.617.2, is […]

Immune system “clock” predicts illness and mortality

You’re as old as your immune system. Investigators at the Stanford University School of Medicine and the Buck Institute for Research on Aging have built an inflammatory-ageing clock that’s more accurate than the number of candles on your birthday cake in predicting how strong your immune system is, how soon […]

Species of gut bacteria linked to enhanced cognition and language skills in infant boys

Infant boys with a higher composition of a particular gut microbiota show enhanced neurodevelopment, according to a new study. The University of Alberta-led research followed more than 400 infants from the CHILD Cohort Study (CHILD) at its Edmonton site. Boys with a gut bacterial composition that was high in the bacteria Bacteroidetes […]

The long view on COVID-19 vaccine safety and efficacy

The mRNA vaccines for COVID-19, made by Pfizer/BioNTech and Moderna, are among the most powerful vaccines the world has ever seen. According to clinical trial data, they are more than 94% effective at preventing symptomatic disease, with real-world data bearing out that success. The other vaccine currently available in the […]

Study IDS Risk Factors for Irregular Heartbeats in Hypertrophic Cardiomyopathy Patients

New research will help doctors identify, treat and prevent potentially dangerous irregular heartbeats in patients with hypertrophic cardiomyopathy, a common heart condition in which the heart thickens and strains to pump blood. These chaotic heart rhythms are known as atrial fibrillation. Atrial fibrillation can be asymptomatic, but it can lead […]

Study Finds COVID-19 Reinfection Rate Less Than 1% for Those with Severe Illness

A review of more than 9,000 U.S. patients with severe COVID-19 infection showed less than 1% contracted the illness again, with an average reinfection time of 3.5 months after an initial positive test. Those are the findings from a study conducted by researchers from the University of Missouri School of Medicine and MU […]

Rats prefer to help their own kind. Humans may be similarly wired

A decade after scientists discovered that lab rats will rescue a fellow rat in distress, but not a rat they consider an outsider, new UC Berkeley research pinpoints the brain regions that drive rats to prioritize their nearest and dearest in times of crisis. It also suggests humans may share […]

Your Immune System Could Turn COVID-19 Deadly

Hidden autoimmunity may explain how the coronavirus wreaks such widespread and unpredictable harm. One of the enduring mysteries of COVID-19 is why it makes some people deathly sick but gives others only mild symptoms or none at all. We know that age matters, as do race; gender; and pre-existing medical […]
