Through gene therapy, researchers engineered blood-forming stem cells (hematopoietic stem/progenitor cells, or HSPCs) to carry chimeric antigen receptor (CAR) genes to make cells that can detect and destroy HIV-infected cells. These engineered cells not only destroyed the infected cells, they persisted for more than two years, suggesting the potential to create long-term immunity from the virus…
Gene expression in specific cells and in specific regions can provide a more precise, neuroprotective approach than traditional treatments for neurological diseases. For multiple sclerosis, specifically, increasing cholesterol synthesis gene expression in astrocytes of the spinal cord can be a pathway to repair nerves that affect walking.
Using molecular scissors wrapped in a greasy delivery package, researchers have disrupted a gene variant that leads to deafness in mice. A single treatment involving injection of a genome editing cocktail prevented progressive hearing loss in young animals that would have otherwise gone deaf, Howard Hughes Medical Institute (HHMI) Investigator David Liu and colleagues report in the journal…
Scientists from the University of California, Los Angeles (UCLA) have developed a new strategy to efficiently isolate, mature and transplant skeletal muscle cells created from human pluripotent stem cells, which can produce all cell types of the body. The findings are a major step towards developing a stem cell replacement therapy for muscle diseases including Duchenne Muscular Dystrophy, which…
Loyola University Medical Center is the only Chicago center that participated in the pivotal clinical trial of a groundbreaking cancer treatment that genetically engineers a patient's immune system to attack cancer cells. Patrick Stiff, MD, director of Loyola's Cardinal Bernardin Cancer Center, is a co-author of the study, published in the New England Journal of Medicine. The treatment used in…
Type 2 diabetes, which affects >0.5 billion people worldwide, results from the inability of beta cells in the pancreatic islets to provide the body with enough insulin to maintain blood glucose levels within the range for a healthy life. A collaborative study led by Prof. Michele Solimena at the Technische Universität in Dresden as well as the Helmholtz Zentrum München, Dr. Anke M Schulte at…
Nitzan Rosenfeld from Cancer Research UK in Cambridge is being honored with the 2017 Meyenburg Award, which carries a €50,000 monetary prize. He receives the award for his excellent work on the detection of tumor DNA in the blood. Rosenfeld has made seminal contributions to advancing a method for detecting cancer DNA in the blood to applicability in cancer medicine. The Meyenburg-Award will be…
A research team in the United States has developed a revolutionary technique that has encoded an image and short film in living cells. Scientists at the Wyss Institute for Biologically Inspired Engineering and Harvard Medical School (HMS) used CRISPR gene editing to encode the image and film in DNA, using this as a medium to store information and produce a code that relates to the individual…
Until now, familial breast cancer has only partly been linkable to genetic risk markers. In a worldwide joint effort, researchers have now identified further genetic variants that affect the risk for breast cancer. The study, which was conducted with participation of researchers from the German Cancer Research Center (DKFZ) and Heidelberg University Hospital, has now been published in Nature.…
Scientists drilling down to the molecular roots of Alzheimer’s disease have encountered a good news/bad news scenario. A major player is a gene called TREM2, mutations of which can substantially raise a person’s risk of the disease. The bad news is that in the early stages of the disease, high-risk TREM2 variants can hobble the immune system’s ability to protect the brain from amyloid beta,…
Cells can be programmed like a computer to fight cancer, influenza, and other serious conditions – thanks to a breakthrough in synthetic biology by the University of Warwick.
Brain scientists from Edinburgh have identified a genetic programme that controls the way our brain changes throughout life. The programme controls how and when brain genes are expressed at different times in a person’s life to perform a range of functions, the study found.
Scientists are honing in on a potential treatment for osteoporosis, after performing the largest ever genetic study of the common age-related bone-thinning disease.
The mouse is the most widely used model organism to understand human genetics, biology, and diseases in the research setting. But new research findings have revealed important divergences between the species which scientists will need to understand better through further investigation.
Every cancer is different and every patient is different. This insight gained in personalised medicine prompted oncology researchers to focus more on the individual patient’s immune system. It is particularly the immune system’s ability to destroy cancer cells that raised hope.
Of the nearly 4 million women in the United States who have had either breast cancer or ovarian cancer, at least 1.5 million have a high risk of carrying certain types of genetic mutations that could increase their risk for additional cancers in the future.
Johns Hopkins Kimmel Cancer Center scientists report they have discovered a biochemical process that gives prostate cancer cells the almost unnatural ability to change their shape, squeeze into other organs and take root in other parts of the body.
Genetics and research, transition and aging, activities and participation, pain orthopedics and physiotherapy as well as new treatment options...
UK-based researchers believe personalised treatment for breast cancer is within sight after uncovering what they say is the most detailed picture to date of which genetic variations contribute to development of the disease.
Non-alcoholic fatty liver disease (NAFLD) is one of the most frequent liver diseases worldwide and an estimated 20 million people in Germany are affected.
Genes do not exist in isolation. So far, little has been known about how the position of a gene on a chromosome affects its evolution.
Although dementia is most often seen in adults, childhood or adolescent dementia does occur. A team of researchers from the University of Würzburg believes that established therapeutic drugs might be effective against childhood dementia.
A new technique – single cell RNA-sequencing – may offer answers and hope to the 200,000 mothers and partners affected by pregnancy loss in the UK every year.
Genetics isn’t just for geneticists anymore. With the rise of direct-to-consumer genetic testing companies like 23andMe, anyone can rifle through their genotypes at hundreds of thousands of positions throughout their DNA. However, these new possibilities may have some serious drawbacks, says Alzheimer's-specialized site Alzforum.
New research has uncovered compelling evidence that genetics plays a major role in how children look at the world and whether they have a preference for gazing at people’s eyes and faces or at objects. The discovery by researchers at Washington University School of Medicine in St. Louis and Emory University School of Medicine in Atlanta adds new detail to understanding the causes of autism…
