Tumors come in many shapes and forms—curable or deadly, solid or liquid, lodged inside the brain, bone, or other tissues. One thing they all have in common, however, is a knack for molecular deceit. It is often by posing as normal cells, or by hijacking them, that cancer cells advance […]

Bioengineers are devising a hot new technology to remotely control the positioning and timing of cell functions to build 3-dimensional, artificial, living tissues. The labs of Kelly Stevens at the UW Medicine Institute of Stem Cell and Regenerative Medicine in Seattle, and Jordan Miller at Rice University in Houston, are collaborating to develop bio-printed, organ-like tissues, […]

New research has uncovered the previously unknown presence of CD19 — a B cell molecule targeted by chimeric antigen receptor (CAR) T cell immunotherapy to treat leukaemia, lymphoma, and multiple myeloma — in brain cells that protect the blood-brain barrier (BBB). This discovery may potentially be the cause for neurotoxicity […]

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 […]

In a new study published neuroscientists at Oxford University have found that raised blood pressure and diabetes in mid-life alter brain structure to slow thinking speed and memory. Looking at results from 22,000 volunteers in the UK Biobank who underwent brain scanning, the scientists found that raised blood pressure and […]

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 […]

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 […]

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 […]

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 […]

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, […]

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 […]

The University at Buffalo has received a four-year, $1.4 million grant from the National Institutes of Health (NIH) to develop a new, portable breast-imaging system that has the potential to better identify breast cancer. Called a dual scan mammoscope (DSM), the device combines light and ultrasound technology to better screen […]
