Aging is not just wear and tear. It is an active process that is driven, at least in part, by chronic inflammation that is the result of immune cell dysfunction. Now, investigators at Stanford University have identified the metabolic switch underlying immune cell switch from function to dysfunction.
In what is claimed as the first co-authored research between regulatory scientists at the U.S. FDA and a commercial manufacturer of organ-on-a-chip devices, CN Bio's Physiomimix system is shown to perform better than the current standard in vitro liver toxicity tests.
BioWorld looks at translational medicine, including: Tau end run prevents memory deficits, but not inflammation; SCLC subtypes have specific vulnerabilities; Turning tsetse fly meal to poison for sleeping sickness control.
LONDON – There’s mixed news about emerging variants of SARS-CoV-2, with Pfizer Inc. and Biontech SE reporting their vaccine Comirnaty maintains its protective effect against B 1.1.7, first detected in the U.K., while researchers in South Africa say virus variant 501Y.V2 is able to escape neutralization by both monoclonal antibodies and convalescent plasma from previously infected individuals.
Researchers at the National Institute of Allergy and Infectious Diseases have shown that optimal control of tuberculosis (TB) infection necessitated immune regulation as well as immune activation – and that PD-1 checkpoint blockers exacerbated TB infections in macaque monkeys by disrupting the balance between the two.
LONDON – A new national consortium of virologists has been set up to systematically assess how mutations in SARS-CoV-2 affect key outcomes such as effectiveness of vaccines and therapies, transmissibility of the virus and the severity of COVID-19 infections. Now is the critical time to do this, as the level of both natural and vaccine-conferred immunity that might drive natural selection is increasing, said Wendy Barclay, head of the department of infectious disease at Imperial College London, who is leading the G2P-UK (Genotype to Phenotype-UK) project.
Alzheimer’s disease can be divided into multiple subtypes based on gene expression patterns, investigators at the Mount Sinai School of Medicine reported in the Jan. 6, 2021, issue of Science Advances. The work, corresponding author Bin Zhang told BioWorld, is “the first major finding of subtypes in Alzheimer’s disease.”
