Persistent immune memory of COVID-19 found in recovered patient T cells

Oxford University researchers have found that natural infection with COVID-19 produces a robust T cell response, including inducing T cell ‘memory’ to potentially fight future infections. The results, published in Nature Immunology, are a joint effort from the Oxford COVID-19 immunology group, led by the Medical Research Council Human Immunology […]

Gene expression altered by direction of forces acting on cell

Tissues and cells in the human body are subjected to a constant push and pull – strained by other cells, blood pressure and fluid flow, to name a few. The type and direction of the force on a cell alters gene expression by stretching different regions of DNA, researchers at […]

New research sheds light on why tumour cells become resistant to chemotherapy

A team of University of Alberta researchers has identified a new mechanism through which tumour cells become resistant to chemotherapy—a discovery that could lead to better treatments for women with breast cancer. Michael Jewer, a post-doctoral researcher in the Faculty of Medicine & Dentistry, said that more than 20 per cent […]

Dementia Prediction

Harvard Medical School investigators based at Massachusetts General Hospital and Beth Israel Deaconess Medical Center have developed a machine learning-based sleep test that shows potential as a biomarker associated with unhealthy brain ageing, including processes leading to dementia. The findings, published in JAMA Network Open, may help clinicians identify patients who have […]

UM171 saves another life

In a world-first, a young man suffering from severe aplastic anaemia who could not be helped by standard treatments has been given a life-saving blood transplant with the made-in-Canada UM171 molecule. The procedure was done by a medical team at the Institute of Hemato-oncology and Cellular Therapy (iHOTC) of Maisonneuve-Rosemont […]

Spinal Cord Stimulation Reduces Pain and Motor Symptoms in Parkinson’s Disease Patients

A team of researchers in the United States and Japan reports that spinal cord stimulation (SCS) measurably decreased pain and reduced motor symptoms of Parkinson’s disease, both as a singular therapy and as a “salvage therapy” after deep brain stimulation (DBS) therapies were ineffective. Writing in the journal Bioelectronic Medicine, […]

Strong activation of anti-bacterial T cells linked to severe COVID-19

A type of anti-bacterial T cells, so-called MAIT cells, are strongly activated in people with moderate to severe COVID-19 disease, according to a study by researchers at Karolinska Institutet in Sweden that is published in the journal Science Immunology. The findings contribute to an increased understanding of how our immune […]

Researchers uncover epigenetic drivers for Alzheimer’s disease

New findings suggest that late-onset Alzheimer’s Disease is driven by epigenetic changes—how and when certain genes are turned on and off—in the brain. Results were published in Nature Genetics. Research led by Raffaella Nativio, a former research associate of epigenetics, Shelley Berger, a professor of genetics, biology and cell and developmental diology and director […]

Women could conceive after ovarian tumours

Women receiving fertility-sparing surgery for treatment of borderline ovarian tumours were able to have children, a study from Karolinska Institutet in Sweden published in Fertility & Sterility shows. Natural fertility was preserved in most of them and only a small proportion required assisted reproductive treatment such as in vitro fertilization. […]

Cancer's Hidden Vulnerabilities

One of the biggest challenges to the development of medical treatments for cancer is the fact that there is no single kind of cancer. Cancers derive from many kinds of cells and tissues, and each has their own characteristics, behaviours, and susceptibilities to anti-cancer drugs. A treatment that works on […]

Insomnia, sleeping less than six hours may increase risk of cognitive impairment

Middle-aged adults who report symptoms of insomnia and are sleeping less than six hours a night may be at increased risk of cognitive impairment, according to a study by Penn State College of Medicine researchers. The results may help health care professionals understand which patients who report insomnia are at […]

Team IDs gene that drives ovarian cancer

High-grade serious ovarian carcinoma (HGSOC) is the fifth-leading cause of cancer-related deaths in women in the United States, yet little is known about the origins of this disease. Now, scientists at the College of Veterinary Medicine have collaborated on a study that pinpoints which specific genes drive – or delay […]

Study tracks how milk nutrients shape infant microbiome

A new study in mice helps explain why gut microbiomes of breastfed infants can differ greatly from those of formula-fed infants. The study, “Dietary Sphinganine Is Selectively Assimilated by Members of the Mammalian Gut Microbiome,” was published in the Journal of Lipid Research. The paper describes an innovative technique developed […]

Study finds that high levels of a growth factor increases risk for several cancers

A study of almost 400,000 British participants has identified a new link between raised levels of the growth factor IGF-1 and increased thyroid cancer risk and has confirmed associations with breast, prostate and colorectal cancer. This could lead to new preventative strategies, including diet and lifestyle interventions. IGF-1 (insulin-like growth […]

Architecture of the heart different between women and men and with age

Differences in the shape and texture of men and women's hearts could potentially explain why their risk of heart disease differs, according to research funded by the British Heart Foundation (BHF). The findings were presented at the European Society of Cardiology (ESC) Congress. Researchers at Queen Mary University of London, […]

Nonalcoholic Fatty Liver Disease and Heart Failure: Is There a Connection?

Heart failure with preserved ejection fraction, or HFpEF, occurs when the contraction of the heart muscle is able to pump blood normally and subsequently has a preserved ejection fraction, but the heart chambers are too stiff to relax and fill properly. In the United States, HFpEF numbers are on the […]

Aging and the costs that come with it

As a high school student, junior Darcey Hookway spent time volunteering on a dementia ward at a local hospital. “The social aspect of their condition really struck me,” says Hookway, who is from London. “They struggled immensely with social isolation. And now with COVID exacerbating that more than ever, I […]

Scientists trace severe COVID-19 to faulty genes and autoimmune condition

More than 10 per cent of people who develop severe COVID-19 have misguided antibodies that attack not the virus, but the immune system itself, new research shows. Another 3.5 per cent, at least, carry a specific kind of genetic mutation. In both groups, the upshot is basically the same: The […]

Placenta is initiated first, as cells of a fertilised egg divide and specialise

The first stages of placental development take place days before the embryo starts to form in human pregnancies. This new finding highlights the importance of healthy placental development in pregnancy, and could lead to future improvements in fertility treatments such as IVF, and a better understanding of placental-related diseases in pregnancy. In […]

Add human-genome produced RNA to the list of cell surface molecules

Bioengineers at UC San Diego have shown that human-genome produced RNA is present on the surface of human cells, suggesting a more expanded role for RNA in cell-to-cell and cell-to-environment interactions than previously thought. This new type of membrane-associated extracellular RNA (maxRNA) is found in human cells that are not […]
