Scientists have uncovered how a key type of immune cell adapts its behavior depending on the type of infection, paving the way for better vaccines and advancing research into immune-related diseases.
In their study published in Nature Immunology, a WEHI-led research team has revealed how T follicular helper (Tfh) cells tailor their instructions to the immune system depending on the pathogen they encounter.
The findings shed light on the molecular “instruction manual” that guides antibody production and long-term immunity, offering new tools to improve vaccine design and develop targeted therapies for immune-related conditions and other major health challenges, including cancer.
Columbia University Medical Center-led research reports that home high-intensity aerobic training improved ataxia symptoms, fatigue, and aerobic fitness more than dose-matched home balance training in individuals with cerebellar ataxias.
Cerebellar ataxias are a group of different disorders marked by progressive loss of coordination that leads to disability. About 150,000 people in the US live with these conditions, with mean annual health care costs above $18,000 per person. Ongoing trials are searching for treatments that slow disease progression and improve functional abilities. Clinical practice guidelines advise balance training for cerebellar ataxia.
Previous work in ataxia has centered on balance-focused programs that can improve Scale for the Assessment and Rating of Ataxia (SARA) scores by 1.0 to 2.8 points when exercises are sufficiently challenging, a range that meets or exceeds the minimal clinically significant difference of 1.0 point.
Scientists from the Gray Faculty of Medical & Health Sciences at Tel Aviv University introduced an innovative gene therapy method to treat impairments in hearing and balance caused by inner ear dysfunction. According to the researchers, “This treatment constitutes an improvement over existing strategies, demonstrating enhanced efficiency and holds promise for treating a wide range of mutations that cause hearing loss.”
The study was led by Prof. Karen Avraham, Dean of the Gray Faculty of Medical & Health Sciences, and Roni Hahn, a PhD student from the Department of Human Molecular Genetics and Biochemistry. The study was conducted in collaboration with Prof. Jeffrey Holt and Dr. Gwenaëlle Géléoc from Boston Children’s Hospital and Harvard Medical School and was supported by the US-Israel Binational Science Foundation (BSF), the National Institutes of Health/NIDCD and the Israel Science Foundation Breakthrough Research Program. The study was featured on the cover of the journal EMBO Molecular Medicine.
Prof. Avraham explains: “The inner ear consists of two highly coordinated systems: the auditory system, which detects, processes, and transmits sound signals to the brain, and the vestibular system, which enables spatial orientation and balance. A wide range of genetic variants in DNA can affect the function of these systems, leading to sensorineural hearing loss and balance problems. Indeed, hearing loss is the most common sensory impairment worldwide, with over half of congenital cases caused by genetic factors. In this study, we aimed to investigate an effective gene therapy for these cases using an approach that has not been applied in this context before.”
Drinking any amount of alcohol likely increases the risk of dementia, suggests the largest combined observational and genetic study to date, published in BMJ Evidence-Based Medicine.
Even light drinking—generally thought to be protective, based on observational studies—is unlikely to lower the risk, which rises in tandem with the quantity of alcohol consumed, the research indicates.
Current thinking suggests that there might be an “optimal dose” of alcohol for brain health, but most of these studies have focused on older people and/or didn’t differentiate between former and lifelong non-drinkers, complicating efforts to infer causality, note the researchers.
Researchers at the University of Stuttgart have created an “optical sieve” capable of detecting minute nanoplastic particles. Functioning much like a test strip, this innovation is designed to provide a new analytical tool for environmental and health research. Researchers from the University of
In a study of human immune cells infected with HIV, the virus that causes AIDS, scientists at Johns Hopkins Medicine say a molecule within HIV itself can be manipulated and amplified to force the virus into long-term dormancy, a state in which HIV does not replicate.
The Johns Hopkins team that conducted the new study had previously shown that the molecule of interest, an “antisense transcript,” or AST, is produced by HIV’s genetic material and is part of a molecular pathway that essentially puts the virus to sleep, a state known as viral latency.
The study’s leader, Fabio Romerio, Ph.D., associate professor of molecular and comparative pathobiology at the Johns Hopkins University School of Medicine, says the new findings add to a growing body of evidence that may help researchers develop a gene therapy that boosts AST production. A report on the research, funded by the National Institutes of Health, was published May 9 in Science Advances.
The health of patients—physical and financial, —depends on how swiftly and efficiently the industry responds to the danger of increasingly sophisticated cyber threats
MBA, PhD, is the Chief Executive Officer of The Parker Institute for Cancer Immunotherapy (PICI — https://www.parkerici.org/), a 501c3 nonprofit organization driving the next generation of cancer treatment by accelerating the development of breakthrough immune therapies to turn all cancers into curable diseases.
Dr. Knudsen most recently served as the Chief Executive Officer of the American Cancer Society (ACS) and ACS Cancer Action Network (ACS CAN), where she led both organizations through a period of transformative growth, significantly expanding research investments, advocacy reach, and direct patient support initiatives. Under her leadership, ACS evolved into a unified, high-performing enterprise, increasing revenue by more than 30 percent and broadening its impact to serve over 55 million lives annually. Moreover, Dr. Knudsen developed and scaled innovative programs that included joint ventures and an impact innovation arm to accelerate progress against cancer.
Prior to ACS, Dr. Knudsen served as Executive Vice President of Oncology Services at Jefferson Health and Enterprise Director of the Sidney Kimmel Comprehensive Cancer Center, growing a multi-state oncology network and spearheading advancements in translational cancer research that increased early access to the most advanced cancer care.
A globally recognized expert in prostate cancer, Dr. Knudsen has authored over 200 scientific publications and generated practice-changing discoveries.
Dr. Knudsen held leadership roles with organizations including the National Cancer Institute Board of Scientific Advisors, the Association of American Cancer Institutes, and the American Association for Cancer Research. She currently serves on the boards of Exai Bio, Paradigm Health, and Research!America, and advises multiple biotech ventures including ArteraAI and Transcarent.
Dr. Knudsen holds numerous awards for her scientific and healthcare accomplishments, and this year will be honored with the Allen Lichter Visionary Leader Award from the American Society of Clinical Oncology (ASCO), recognizing her lifetime achievement of outstanding contributions to the field of oncology.
A new study shows that the brain benefits of exercise may be partly replicated with an IV infusion of lactate, the by-product of intense physical activity.
A 2018 review became the first meta-analysis to quantify the impact of what they termed “greenspace exposure”. It sifted through five online databases leading up to January 2017 to look at the health outcomes of exposure to the great outdoors and found that “green prescriptions” could have substantial benefits to human health.
Perks mentioned included decreased salivary cortisol (the “stress hormone”), lower heart rate, blood pressure, and cholesterol, among others.
“Incidence of stroke, hypertension, dyslipidaemia, asthma, and coronary heart disease were reduced,” wrote the authors. “For several non-pooled health outcomes, between 66.7% and 100% of studies showed health-denoting associations with increased greenspace exposure, including neurological and cancer-related outcomes, and respiratory mortality.”
