Repulsion mechanism between neurons governs fly brain structure

Researchers at Kanazawa University report in Nature Communications the discovery that in the developing fly brain, neurons stemming from the same parent cell experience repulsion. This lineage-dependent repulsion is regulated by a protein known as Dscam1. The brain’s structure has columnar features, which are hypothesized to arise from nerve cells […]

Genetic Study Uncovers Mutation Associated with Fibromuscular Dysplasia

Understanding of fibromuscular dysplasia (FMD), a rare blood vessel disease, is making the jump from the laboratory to the clinic with new findings of a genetic variant. Researchers found the mutation in a gene that is associated with classical Ehlers-Danlos Syndrome as well, in multifocal FMD. That means it could […]

Trial finds benefit of immunotherapy-chemotherapy combination in early-stage triple-negative breast cancer

Adding an immunotherapy agent to a three-drug chemotherapy regimen can improve the likelihood that early-stage triple-negative breast cancer will recede to undetectable levels, data from a clinical trial led by Dana-Farber/Brigham and Women’s Cancer Center suggests. The results of the trial, dubbed the IMpassion031 study, will be presented at the […]

Scientists advance understanding of blood-brain barrier health with implications for brain disease

Hard skulls help protect our brains from physical injuries. In addition to a tough outer shell, brains have internal defences, including a powerful shield called the blood-brain barrier that defends brain cells from substances in the bloodstream that are toxic and dangerous to nerve cells. If the blood-brain barrier is […]

Shared protein fingerprint could simplify treatment of common inherited heart disease

Hypertrophic cardiomyopathy is the most common inherited heart disease, marked by an abnormally thickened heart muscle that can obstruct blood flow and lead to sudden death in young adults. A dizzying array of over 1,400 genetic mutations can lead to the disease, puzzling doctors on how to treat so many […]

The Aging of Macrophages Impairs Peripheral Nerve Regeneration

Macrophages of the innate immune system, cells derived from monocytes, are involved in many processes in tissue beyond merely hunting down invading pathogens. They are also important to the processes of tissue maintenance regeneration following injury. Like all aspects of the immune system, macrophage behavior becomes dysregulated with age, a […]

Twist on CRISPR Gene Editing Treats Adult-Onset Muscular Dystrophy in Mice

Myotonic dystrophy type I is the most common type of adult-onset muscular dystrophy. People with the condition inherit repeated DNA segments that lead to the toxic buildup of repetitive RNA, the messenger that carries a gene’s recipe to the cell’s protein-making machinery. As a result, people born with myotonic dystrophy […]

Is turning back the clock in aging fat cells a remedy for lifestyle diseases?

No matter how much we try and fight it, aging is a part of life. High cholesterol, diabetes, and fatty liver, the collection of conditions referred to as lifestyle diseases, all become more commonplace as we get older. Interestingly, however, many of these age-related conditions are caused by changes inside […]

Researchers discover new molecules for tracking Parkinson’s disease

The study describes an innovative approach for identifying and evaluating candidate molecules that can image and track the progression of a wide range of neurodegenerative diseases. For any of the 200,000 patients diagnosed with Parkinson’s disease in the United States every year, the diagnosis often occurs only after the appearance of […]

Lowered Body Temperature is Important in the Beneficial Calorie Restriction Response

Calorie restriction lowers body temperature in mammals, but most research on how reduced calorie intake produces benefits to long-term health and longevity has focused on nutrient sensing as the primary trigger for the upregulation of stress responses and other helpful changes to cellular metabolism. Here, researchers demonstrate that reduced body […]

Higher Temperature Slows Osteoporosis, an Effect Mediated by Polyamine Produced by Gut Microbes

Osteoporosis is the name given to the characteristic age-related loss of bone mass and strength. The extracellular matrix of bone tissue is constantly remodeled, created by osteoblasts and broken down by osteoclasts. The proximate cause of osteoporosis is a tilt in the balance of these processes, favoring osteoclast activity and […]

Medical cannabis can help cancer patients to get rid of chemotherapy side effects

Most people use cannabis for recreation. They don’t really care about the positive health effects that cannabis might have. However, cannabis is being researched for its positive characteristic against many chronic health conditions. Now scientists in Australia found that cancer patients could benefit from medical cannabis. Scientists from the University […]

RNA quality control system goes awry in frontotemporal lobar degeneration

Researchers at Osaka University have identified a fault in the RNA quality control system of cells that leads to the haywire production of toxic proteins in frontotemporal lobar degeneration and amyotrophic lateral sclerosis (FTLD/ALS). Their new study, published in The EMBO Journal, shows that an abnormality of the C9orf72 gene […]

New cancer screening study could affect treatment for thousands in the UK

The first UK study to estimate the proportion of womb cancers caused by an inherited cancer predisposition called Lynch syndrome has been carried out by The University of Manchester. Almost 3% of womb cancers are linked to a hereditary condition named Lynch syndrome, according to new clinical research findings published […]

Parkinson’s trigger in focus for new international research project

A three-year grant from the Aligning Science Across Parkinson’s initiative will support the most in-depth look at the cellular mechanisms that lead to Parkinson’s disease to date. Leading researchers from the USA and Garvan will use cutting-edge technology to reveal the complex interplay of genes, molecules, cells and age-related factors […]

Researchers find 'cellular compass' guides stem cell division in plants

The stem cells tasked with creating and maintaining biological tissues have a difficult job. They have to precisely divide to form new specialized cells, which are destined to different fates even though they contain identical DNA. An obvious question then is: How do the cells divide in all the right […]

Mosquito-borne viruses linked to stroke

A deadly combination of two mosquito-borne viruses may be a trigger for stroke, new research published in The Lancet Neurology has found. University of Liverpool researchers and Brazilian collaborators have been investigating the link between neurological disease and infection with the viruses Zika and chikungunya. These viruses, which mostly circulate in […]

Kang finds keys to control the ‘driver of cancer’s aggressiveness’

“Do not erase.” “Recycle me.” “Free to a good home.” Humans post these signs to indicate whether something has value or not, whether it should be disposed of or not. Inside our cells, a sophisticated recycling system uses its own enzymatic signs to flag certain cells for destruction — and […]

Shoes with ‘toe springs’ give your feet a break, but beware of long-term pain

Your spine deteriorates naturally over time, even if you tread lightly and are mindful of good posture. Radiologists are keenly aware of this truth due to an endless queue of patients with low back pain whose imaging scans reveal no acute injury but, instead, show typical signs of activity, gravity, […]

Middle-Aged Individuals May Be in a Perpetual State of H3N2 Flu Virus Susceptibility

Penn Medicine researchers have found that middle-aged individuals — those born in the late 1960s and the 1970s — may be in a perpetual state of H3N2 influenza virus susceptibility because their antibodies bind to H3N2 viruses but fail to prevent infections, according to a new study led by Scott Hensley, […]
