Multiple companies are pursuing CD47-blockade as a tumor immunotherapy approach. Sana Biotechnology Inc., too, is interested in the therapeutic potential of CD47 – but from a very different angle. By overexpressing CD47 on stem cells, researchers at Sana want to make transplanted cells invisible to the immune system.

Sometimes, scientific progress comes from conceptual insights that arrive in a flash. More often, however, such progress arrives in a decidedly less glamorous, though no less important, manner – through the development of new technologies in what can be a very slow iterative cycle of getting a new method to work.

Researchers from The Hong Kong Polytechnic University (PolyU) said they have used two-dimensional nanosheets (FePSe3) to develop a biomimetic nanosheet that can monitor tumor development, treat tumors and monitor the treatment progress in real-time. With positive results from mice, the team hopes to further test it on larger animals, then move on to clinical studies.

Researchers at Oregon Health & Science University have turned acetaminophen's toxicity into an asset, using it to select genetically modified hepatocytes in vivo.

Researchers at the University of Washington reported in the May 31, 2021, issue of Nature Medicine that artificial intelligence (AI) algorithms meant to recognize COVID-19 infections based on chest X-rays picked up on confounders, selecting “shortcuts” such as patient age or positioning in the X-ray as a basis for their predictions.

At the 2021 virtual annual meeting of the American Society for Clinical Oncology (ASCO), results of the VISION trial testing the addition of Novartis AG’s radiopharmaceutical Lutetium-177-PSMA-617 (Lutetium-PSMA) to individualized standard-of-care regimens in metastatic castration-resistant prostate cancer improved both overall survival and radiographic progression-free survival.

Parkinson’s disease (PD) is one of the most common neurodegenerative diseases, and the role of ?-synuclein accumulation and the subsequent death of dopaminergic neurons in the midbrain have long been recognized as key steps in the disease. Progress in understanding genetic risk factors, meanwhile, has uncovered multiple genetic risk factors. Even though aging is the single biggest risk factor for PD, there are versions of the disorder that affect children.

Data on the prevalence of diabetes in the U.S. show that non-Hispanic white people are least likely to suffer from the disease. Yet to date most genetic studies of the glycemic traits that are used to diagnose and monitor type 2 diabetes and cardiometabolic health have focused on individuals of European ancestry.

The Research to Accelerate Cures and Equity for Children Act is leading to deep changes in pediatric cancer research. Passed in 2017 and fully implemented in 2020, the RACE Act requires companies to investigate targeted drugs for adult cancers in pediatric cancers as well “when the molecular target of the drugs are substantially related to a pediatric cancer.”

LONDON – New guidelines for stem cell research open the door to extending the legal limit on human embryo research beyond the current 14-day maximum set down 40 years ago. In revised guidelines, the International Society for Stem Cell Research (ISSCR) has moved research on human embryos from category 3, which explicitly bans their study in culture post 14 days in any circumstances, to category 2B, in which research post 14 days would be permissible if there is a clear scientific rationale – and after a thorough specialized review.
