When the immune system encounters a virus, it produces antibodies designed to recognize and eliminate the invader. But in some people infected with SARS-CoV-2, the virus that causes COVID-19, the immune response goes awry, producing autoantibodies—antibodies that mistakenly attack the body’s own tissues.
Results from an early-stage clinical trial, published in Nature Communications, showed encouraging outcomes among patients with newly diagnosed cancer whose tumors had spread to distant organs.
Researchers at the Center for Regenerative Medicine (CReM) at Boston Medical Center (BMC) and Boston University (BU) have developed a scalable method for generating CD4+ helper T cells from induced pluripotent stem cells (iPSCs), overcoming a longstanding challenge in the development of stem cell-based immunotherapies.
When researchers at Lund University investigated how UM171, a molecule used to make blood stem cells multiply, works, they made an unexpected connection. The results provide new insights into how one of the most common malignant brain tumors in children could be treated in the future. Their research is published in the journal Cancer Gene Therapy.
The number of people who need prescription glasses to correct their vision is increasing each year as nearsightedness, or myopia, becomes more common worldwide. Current projections suggest cases could reach 50% by 2050, affecting nearly 5 billion people.
Exercise does more than keep our minds and bodies healthy. It also protects us against the effects of aging. Scientists have developed self-contracting mini-muscle implants that grow their own blood supply and mimic the biological benefits of exercise, giving people unable to work out because of physical limitations a way to reap the same rewards.
What if amyloid plaques are not the whole story of Alzheimer’s disease? New research suggests that a broad range of Alzheimer’s pathologies may be orchestrated by a molecular switch called ERBB4 when it turns on in the wrong neurons. Once activated, this misplaced signal can set off a chain reaction that disrupts brain circuits, eliminates synapses, activates glial cells, increases amyloid pathology and impairs memory.
Researchers have developed a “scaffold” that mimics natural tissue and could lead to more durable rotator cuff repairs, including for large injuries and cases involving bone and tissue degeneration that are often the most difficult to fix. Devised by a team at the Perelman School of Medicine at the University of Pennsylvania, the new system was detailed in Science Advances.
A researcher in Chicago remotely controls a miniaturized brain implant in Daejeon, Korea—over the internet. Korean researchers have developed a wireless device that can deliver drugs and light to precisely modulate targeted neurons from anywhere in the world.
The blood–brain barrier (BBB) is a protective filter that lines the brain’s blood vessels and is notoriously hard to penetrate, making the treatment of brain disorders very difficult. Strategies designed to breach the BBB include using brain surgery and focused ultrasound waves to create physical openings for the transportation of medicines and employing engineered adeno-associated viruses (AAVs) to ferry genetic payloads into desired locations, but these methods have limitations. Now, researchers at Caltech have developed a new, more effective way to transport potentially life-changing therapeutics across the BBB.
