New database aims to make Alzheimer's diagnosis easier and earlier

Volunteers can add data with a five-minute online session. Do you get nervous when you can’t think of a word? Chances are it’s a momentary lapse, but problems with language are one of the symptoms that can indicate a neurodegenerative disorder like Alzheimer’s disease. Unfortunately, diagnosing these conditions requires scoring […]

Sensory Neurons Outside the Brain Drive Autistic Social Behaviors, Penn Study Suggests

A new study from Penn Medicine lends further evidence that the social behaviors tied to autism spectrum disorders (ASD) emerge from the abnormal function of sensory neurons outside the brain. It’s an important finding, published in the journal Cell Reports because peripheral sensory systems—which determine how we perceive the environment around us […]

New molecular tool precisely edits mitochondrial DNA

UW microbiologists discovered a bacterial toxin that, when engineered, is a key part of a gene editor that can make single-base changes in human mitochondria. The genome in mitochondria — the cell’s energy-producing organelles — is involved in disease and key biological functions, and the ability to precisely alter this […]

Dissecting fruit flies’ response to life-extension diet

Changes in a few small molecules involved in a cell’s metabolism seem to indicate whether a restricted “life extension” diet will actually extend, shorten, or have no effect on lifespan, a study of fruit flies has found. The findings suggest that analyzing the level of small molecules in cells, an […]

Yale, Baylor create detailed atlas of cellular change in lungs with fibrosis

A research team from Yale and Baylor College of Medicine has completed the largest single-cell analysis to date of lungs affected by Idiopathic Pulmonary Fibrosis (IPF), revealing how cells change in response to the disease and identifying previously unknown cell types. The findings, published in the issue of Science Advances, deepen […]

Brd2 Inhibition as an Approach to Slow Aging

There are innumerable studies showing small gains in mouse life span. Most cannot be reproduced, particularly the older ones, those that took place before it was common knowledge in the research community that one has to very aggressively control for accidental calorie restriction. If an intervention makes mice eat less, […]

The Aging Gut Microbiome Produces More Trimethylamine, Harming Arterial Function

In recent years academic interest has grown in the study of the gut microbiome. Researchers are making inroads into understanding the considerable influence of these microbial populations over the progression of health and aging. The gut microbiome may be as influential as physical activity in these matters. The balance of […]

Zika infection after birth shown to have long term brain and behavior issues in animals

Emory University researchers have shown that Zika virus infection soon after birth leads to long-term brain and behavior problems, including persistent socioemotional, cognitive and motor deficits, as well as abnormalities in brain structure and function. This study is one of the first to shed light on the potential long-term effects […]

Antibodies against lipid gives protection against rheumatic systemic disease

A novel study from the Institute of Environmental Medicine at Karolinska Institutet indicates that antibodies against a small lipid entity, phosphorylcholine (PC), can be associated with protection in inflammatory systemic diseases, including SLE and Sjögren´s syndrome. The results support evidence for a potential treatment by providing antibodies (anti-PC) to patients […]

Ex Vivo Mitochondrial Transfer as a Way to Improve Stem Cell Therapy Outcomes

A sizable portion of the variable efficacy of first generation stem cell therapies as presently practiced may be due to a poor quality of cells following expansion in culture. Regardless of quality, near all such cells die shortly after transplantation. Few clinics and few approaches to cell therapy lead to […]

Ageing research: Low levels of the stress hormone cortisol contribute to ageing

Why do we age? What exactly happens in the body? And: Can something be done about it? These are questions that have occupied science since time immemorial. The pharmacists Alexandra K. Kiemer and Jessica Hoppstädter from the Saarland University have not found a philosophical stone. But: they have uncovered processes […]

Team develops new approach to treat certain neurological diseases

Research produces dramatic results in laboratory studies involving fatal myelin disease that strikes children. A team led by Case Western Reserve University medical researchers has developed a potential treatment method for Pelizaeus-Merzbacher disease (PMD), a fatal neurological disorder that produces severe movement, motor and cognitive dysfunction in children. It results […]

Targeting Cellular Senescence as an Intervention in Aging

Senolytic drugs that destroy senescent cells, and later on, other senotherapies that either prevent senescence or block the senescence-associated secretory phenotype (SASP), are going to be very important in the treatment of aging. Senescent cells accumulate with age and are highly damaging to tissues. Via the SASP, even comparatively small […]

Aging Impacts Progenitor Cells in the Thymus

The age-related decline of the immune system has several causes, but the involution of the thymus is an important one. The thymus is responsible for the production of mature T cells of the adaptive immune system, but the organ atrophies with age. The supply of new T cells falls off […]
