Psychiatric animal models are a challenge by their nature. Whether a drug is blocking tumor growth in a rodent is easy enough to measure, although still hard to translate. But how does one figure out what a mouse is thinking? Actually, one doesn’t. There is “no way in heck I’m going to claim that I can model a thought disorder in rodents, so forget about that,” Bita Moghaddam told her audience at the opening keynote of the European College of Neuropsychopharmacology (ECNP) annual conference this weekend. But other aspects of mental disorders, she argued, can be usefully modeled.
“Epilepsy is really a classical neurological disorder,” Lars Pinborg told the audience at the European College of Neuropsychopharmacology (ECNP) annual conference on Sunday. “Or is it?” Pinborg, of Rigshospitalet's The Neuroscience Center in Denmark, was chairing a session dedicated to an alternative hypothesis, summed up in the session title: “Is epilepsy a psychiatric disorder?”
Scientists from the Global Biobank Meta-Analysis Initiative (GBMI) , founded in 2019, have published initial results in the Oct. 12, 2022 issue of Cell Genomics. In a series of papers, the investigators showed that the data collected by multiple biobanks could be harmonized and jointly analyzed, despite initial differences in recruitment strategies, sample collection, and definitions of diseases. Joint analysis identified new risk loci for more than a dozen common diseases, while another paper showed that such joint analysis could also be used to identify such loci for the rare disease idiopathic pulmonary fibrosis (IPF).
Researchers at the University of Cincinnati have published data showing that in patients with dominantly inherited Alzheimer’s disease-causing mutations, high levels of soluble amyloid-β42 (Aβ42) in the cerebrospinal fluid predicted a reduced risk of developing dementia over three years.
Researchers at the University of Cincinnati have published data showing that in patients with dominantly inherited Alzheimer’s disease (AD)-causing mutations, high levels of soluble amyloid-β42 (Aβ42) in the cerebrospinal fluid (CSF) predicted a reduced risk of developing dementia over 3 years. Their work, which appeared in the Oct. 4, 2022, print issue of the Journal of Alzheimer’s Disease after earlier publication online, suggests that the problem with amyloid in AD may be a lack of soluble amyloid-β, rather than a surfeit of plaques.
By independently manipulating the lifespan of worms and one of its purported biomarkers, namely, the cessation of vigorous movement (CVM), investigators at the Center for Genomic Regulation (CRG) in Barcelona have demonstrated that the two are driven by partly independent processes.
The 2022 Nobel Prize in chemistry was awarded to Carolyn Bertozzi of Stanford University, to Morten Meldal of the University of Copenhagen, and – for the second time – to Barry Sharpless of The Scripps Research Institute “for the development of click chemistry and bioorthogonal
chemistry.”
Click chemistry, the Nobel Committee’s Olof Ramström told reporters while announcing the prize, “is almost like it sounds – it’s all about linking different molecules.”
He likened click chemistry to a seatbelt buckle, whose interlocking parts can be attached to many different materials, linking them by snapping the two parts of the buckle together.
“The problem was to find good chemical buckles,” Ramström said – chemicals that “will easily snap together, and importantly, they won’t snap with anything else.”
The 2022 Albert Lasker Basic Medical Research Award has been awarded to Richard Hynes, of the Massachusetts Institute of Technology, Erkki Ruoslahti, of the Sanford Burnham Prebys Medical Discovery Institute, and Timothy Springer, of Harvard Medical School.
The Nobel Prize in Physiology or Medicine 2022 was awarded to Svante Pääbo today "for his discoveries concerning the genomes of extinct hominins and human evolution." Pääbo, who is currently the director of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and his colleagues overcame extreme technical challenges to sequence the DNA of ancient hominids – because after tens of thousands of years, there is no such thing as aging well for DNA.
The 2022 Albert Lasker Basic Medical Research Award has been awarded to Richard Hynes, of the Massachusetts Institute of Technology, Erkki Ruoslahti, of the Sanford Burnham Prebys Medical Discovery Institute, and Timothy Springer, of Harvard Medical School “for discoveries concerning the integrins, key mediators of cell-matrix and cell-cell adhesion in physiology and disease.”
