Putting the brakes on immune reactions

When we are exposed to a pathogen, the immune system’s B cells swarm to our lymph nodes, spleens, and tonsils. There, those cells mutate in germinal centers—microscopic boot camps that rush the B cells through volleys of mutations to produce the most potent antibodies for neutralizing the infectious agent. As […]

Hunting for TB's most vulnerable genes

Developing drugs to combat tuberculosis, or TB, can be frustrating business. A gene essential to the bacteria’s lifecycle is discovered, scientists rush to develop drugs that inhibit the target, and then—disappointment. Volleys of compounds hurled at the essential gene target have little impact on microbial growth. The bacteria live on. […]

‘Good cholesterol’ may protect liver

The body’s so-called good cholesterol maybe even better than we realize. New research from Washington University School of Medicine in St. Louis suggests that one type of high-density lipoprotein (HDL) has a previously unknown role in protecting the liver from injury. This HDL protects the liver by blocking inflammatory signals […]

Delay Tactics

Elevated levels of three specific circulating proteins are associated with protection against kidney failure in diabetes, according to new research from Harvard Medical School researchers at Joslin Diabetes Center published in Science Translational Medicine. “As well as acting as biomarkers for advancing kidney disease risk in diabetes, the proteins may also […]

Fasting and behavior

Over the last decade, investigators at Beth Israel Deaconess Medical Center have been at the forefront of the effort to identify the small population of neurons deep within the brain that causes hunger. But precisely how these cells and the unpleasant feeling of hunger they cause actually drive an animal to […]

Lead in Drinking Water: Unsafe at Any Level

No amount of lead in drinking water is safe for people with kidney disease, study shows Despite advances in reducing the amount of lead in drinking water, low levels of contamination remain widespread throughout the United States. This may be especially dangerous for the 30 to 40 million Americans living […]

Changes in gut microbiome in longitudinal study of infants precede onset of celiac disease

By implementing a long-term, prospective approach to the development of celiac disease, a collaborative group of researchers has identified substantial microbial changes in the intestines of at-risk infants before disease onset. Using advanced genomic sequencing techniques, MassGeneral Hospital for Children (MGHfC) researchers, along with colleagues from institutions in Italy and […]

New campaign highlights need to seek help for ‘vague but concerning’ cancer symptoms

The six-month campaign will target parts of South Wales with poor cancer survival rates and highlight six possible symptoms, including unexplained weight loss, loss of appetite, nausea, persistent fatigue, abdominal pain and “not feeling yourself”. The initiative aims to encourage adults in the Cwm Taf Morgannwg University Health Board area […]

New study provides clues to decades-old mystery about cell movement

A new study, led by University of Minnesota Twin Cities engineering researchers, shows that the stiffness of protein fibers in tissues, like collagen, are a key component in controlling the movement of cells. The groundbreaking discovery provides the first proof of a theory from the early 1980s and could have […]

Genetics could explain why some people get severe COVID-19

One of the greatest mysteries of the COVID-19 pandemic is why some people fall severely ill while others suffer nary a sniffle. Now, after compiling data from around the world, researchers have determined that the answer seems to lie, in part, in genetics. Through an international meta-analysis of studies from more than […]

Researchers develop tool to drastically speed up the study of enzymes

For much of human history, animals and plants were perceived to follow a different set of rules than rest of the universe. In the 18th and 19th centuries, this culminated in a belief that living organisms were infused by non-physical energy or “life force” that allowed them to perform remarkable […]

3D imaging reveals neural ‘vicious cycle’ in fatty liver disease

With the application of a novel three-dimensional imaging technology, researchers at Karolinska Institutet have discovered that one portion of the autonomic nervous system in the liver undergoes severe degeneration in non-alcoholic fatty liver disease. The study, which is conducted in mice and human liver tissue, shows that the degeneration of […]

How promiscuous protein droplets regulate immune genes

Biochemists at Emory are achieving insights into how an important regulator of the immune system switches its function, based on its orientation and local environment. New research demonstrates that the glucocorticoid receptor (or GR) forms droplets or “condensates” that change form, depending on its available partners. Understanding how the GR […]

COVID-19 survivors may possess wide-ranging resistance to the disease

Recovered COVID-19 patients retain broad and effective longer-term immunity to the disease, suggests a recent Emory University study, which is the most comprehensive of its kind so far. The findings have implications for expanding understanding about human immune memory as well as future vaccine development for coronaviruses. The longitudinal study, […]

Toxicity testing on the placenta and embryo

Researchers at ETH Zurich have developed a cell culture test to detect substances that are directly or indirectly harmful to embryos. Based on an existing test used for developing new drugs and chemicals, the augmented version is designed to help reduce the number of animal experiments. Drugs must be safe […]

Researchers identify signaling molecule that may help prevent Alzheimer’s disease

New research in humans and mice identifies a particular signaling molecule that can help modify inflammation and the immune system to protect against Alzheimer’s disease. The work, which was led by investigators at Massachusetts General Hospital (MGH), is published in Nature. Cognitive decline associated with Alzheimer’s disease develops when neurons begin to die. “Neuron […]

Highly accurate protein structure prediction with AlphaFold

Understanding the structure of proteins can help understand their function; however, existing computational methods fail to predict 3D structures of proteins with atomic accuracy. Thankfully, a recent paper on Nature introduces a redesigned version of a neural network-based model AlphaFold. It can predict protein structures with accuracy competitive with the experiment […]

What Vaping Does to the Human Body?

The topic of vaping is subject to many ongoing discussions. Manufacturers often say this is 'less harmful' alternative to typical cigarettes which also helps quitting smoking. But there are lots of scientific studies contradicting this claim. Different research teams point to unique and undesirable side effects, such as increased susceptibility […]

Study reveals source of remarkable memory of “superagers”

As we age, our brains typically undergo a slow process of atrophy, causing less robust communication between various brain regions, which leads to declining memory and other cognitive functions. But a rare group of older individuals called “superagers” have been shown to learn and recall novel information as well as […]
