The Role of Aging Macrophages in Skin Inflammation

The immune system is complex and ages in complex ways, pressed by the lifetime burden of infection and rising levels of molecular damage that trigger many of the same innate immune responses as are produced by invading pathogens. The common innate immune cells known as macrophages play many roles in […]

Is There Really a Solid Correlation Between Periodontitis and Risk of Neurogenerative Disease?

A number of papers in recent years have suggested there to be a link between gum disease (periodontitis) and neurodegeneration. Similarly to the correlation with heart disease, it is thought that the underlying mechanism is raised chronic inflammation deriving from toxins released into the bloodstream by the bacteria that cause […]

Microbiome Medicine: Scientists Harness the Body’s ‘Bugs’ to Treat Asthma, MS, and More

Plenty of probiotic yoghurts, pickles, and kombuchas claim to boost our digestive health with armies of microbes, but some scientists have more ambitious therapeutic plans for the “bugs” that colonize us. They hope to leverage these microbes as living therapeutics for a range of health conditions, including ulcerative colitis, multiple […]

How do sugary beverages affect the liver?

When people overconsume sugar-sweetened beverages, or SSBs, like soda, certain fruit juices, and some coffee and tea drinks, it can lead to many different health conditions, including obesity, cardiovascular disease and diabetes. Nonalcoholic fatty liver disease, or NAFLD, is the leading cause of liver disease in the United States, and […]

New TAU method delivers therapeutic RNAs exclusively to cancer cells

Researchers at Tel Aviv University have created a new method of transporting RNA-based drugs to a subpopulation of immune cells involved in the inflammation process, and target disease-inflamed cells without causing damage to healthy cells that surround them. The new technology may revolutionize the treatment of cancer and a wide range of […]

Researcher seeks molecular causes for deadly lung, heart diseases

Yassine Sassi decided as a boy growing up in Tunisia that he wanted to be a scientist. He isn’t sure why. There were no scientists among his family, no friends with the same ambition. But at 18 he left home for France to study biochemistry. Two decades later, he’s on […]

Studying how microbiome affects immunity could improve vaccine effectiveness

So many microbes live in and on your body that it might be helpful to think of them functioning collectively as separate organs. That’s because these tiny organisms that live primarily in our gut, collectively known as the microbiome, often perform helpful functions that keep the body running smoothly. Scientists […]

New Treatment Stops Progression of Alzheimer’s Disease in Monkey Brains

Therapy Manipulates the Immune System to Slow Neurodegeneration Without Triggering Dangerous Inflammation in the Process. A new therapy prompts immune defense cells to swallow misshapen proteins, amyloid beta plaques and tau tangles, whose buildup is known to kill nearby brain cells as part of Alzheimer’s disease, a new study shows. […]

Carotenoid-Rich Diet Reduces Risk of Developing AMD

A Mediterranean diet – high in fruit, vegetables, legumes, whole grains, olive oil and oily fish – may prevent the development of age-related macular degeneration (AMD), which is the leading cause of visual impairment in people over the age of 50. A new study published by researchers from Inserm and […]

Do Bacteria in the Mouth Affect Risk of Developing Rheumatoid Arthritis?

Investigators found similarities in the bacterial composition of the mouth among patients with early rheumatoid arthritis and those at risk of developing the disease, compared with healthy individuals who were not at risk. The findings come from a study published in Arthritis & Rheumatology. Patients and at-risk individuals had an […]

Reliable Assessment of Cognitive Function

Multiple sclerosis is a chronic autoimmune disease of the central nervous system. Cognitive impairment is a sometimes neglected, yet common, sign and symptom with a profound effect on instrumental activities of daily living. Even before diagnosis, patients may experience cognitive dysfunction that manifests through symptoms such as memory lapses or […]

Arctic rotifers still alive after 24,000 years in a frozen state

Bdelloid rotifers are multicellular animals, so small a microscope is needed to see them. Despite their size, they're known for being tough — capable of surviving drying, freezing, starvation and low oxygen. Now, U.S. National Science Foundation-funded researchers have found that not only can they withstand being frozen, but they can […]

Reducing Pain in the NICU

Babies in the neonatal intensive care unit (NICU) experience a lot of testing in the early days of their life, and research shows the associated pain and trauma can contribute to long term neurological deficits. Matthew Bizzarro, MD and Steven Peterec, MD were at a conference on the effects of pain on the […]

New Fralin Biomedical scientist explores how metabolism, stress alter gene expression in heart cells

Human heart muscle cells are constantly at work – contracting roughly a million times a week in adults. Jessica Pfleger, a new assistant professor joining the Fralin Biomedical Research Institute at VTC’s Center for Vascular and Heart Research, studies how the heart’s genes are regulated in response to stimulation and stress. Her […]

Switching to 80% ULTRA-processed food diet for 30 days: What would happen?

Eating healthy is not easy. This is especially true today, when all the supermarkets are full of ready-made, ready-to-eat kinds of food. It is no wonder why many people choose such products on a daily basis: these ultra-processed meals are produced to taste good, are relatively inexpensive, and do not […]

Study identifies heart block cause in athletes

An international team of scientists from Manchester, Montpellier and Copenhagen have identified why some endurance athletes experience a heart rhythm disturbance called ‘heart block’. The University of Manchester-led study found that long-term exercise in retired racehorses – the best available model of the athlete’s heart – and in mice, triggered […]

As novel sights become familiar, different brain rhythms and neurons take over

As “visual recognition memory” emerges in the visual cortex, one circuit of inhibitory neurons supplants another, and slower neural oscillations prevail. To focus on what’s new, we disregard what’s not. A new study by researchers at MIT’s Picower Institute for Learning and Memory substantially advances understanding of how a mammalian […]

Soil microbes metabolize the same polyphenols found in chocolate, wine

Fruits, vegetables, red wine and chocolate are all rich in polyphenols, plant compounds that double as cancer-fighting antioxidants. Humans can access these foods' health benefits because the microbes in our guts happily feast on them, breaking them down into smaller chemical components. Microbiome scientists at Colorado State University wanted to know if […]

Platinum-chemotherapy can enhance the treatment resistance of ovarian cancer cells

Researchers from Karolinska Institutet have discovered how platinum-chemotherapy can enhance the treatment resistance of ovarian cancer cells, by progressively changing the cancer cell-intrinsic adhesion signalling and cell-surrounding microenvironment. Platinum chemotherapy is a standard treatment in ovarian cancers, but treatment resistance commonly develops. The extracellular matrix (ECM)-derived biochemical and mechanical cues […]
