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.
Roughly a year and a half after the start of the COVID-19 pandemic, many unknowns remain about the future of the virus. How it will mutate, how long protection from either illness or vaccination will last, when it will cease to be a pandemic and instead be endemic, even whether the worst is still ahead. And there is also an increasing acknowledgment that there remain unknowns about SARS-CoV-2’s past.
Collectively, lysosomal storage disorders (LSDs) are caused by malfunctions in metabolic enzymes in the lysosome system. Depending on which enzyme is missing, toxic metabolites accumulate. While the LSDs are highly heterogenous – even within one disease, presentation can vary widely – neurodegeneration is a common feature in these disorders.
Parasitic worms, or helminths, are a major global health issue. At the same time, "parasites have been a prolific area of biomedical research to emerge," De'Broski Herbert told his audience at the 2021 annual meeting of the American Association of Immunologists.
An international collaborative study led by scientists at Sweden’s Lund University has classified Alzheimer’s disease into four distinct subtypes, which has important implications for the management of the progressive neurodegenerative disease, the authors reported in the April 29, 2021, edition of Nature Medicine.
Using advanced intravital microscopy to visualize immune cell movement within the tissues, investigators at the Peter Doherty Institute for Infection and Immunity, Melbourne have discovered that the neurotransmitter noradrenaline produced by the sympathetic nervous system causes a dramatic paralysis of immune cell movement.
Researchers have gained new insights into what makes for transplantable livers – and what doesn’t. In a clinical trial of 12 livers, a team from Massachusetts General Hospital showed that both livers with high fat content and those without could be viable for transplantation.
BioWorld looks at translational medicine, including: Neurons forget who they are in Alzheimer’s disease; Sensor can predict hallucinogenic serotonin receptor effects.
