Dispute simmers over who first shared SARS-CoV-2 ’s genome
When GISAID, the widely used database for influenza and SARS-CoV-2 genomes, issued a statement last week about a set of controversial sequences from the Huanan Seafood Wholesale Market in Wuhan, China, the release explained by way of background that the repository was “an essential contributor to global health” trusted by thousands of data contributors from 215 nations and territories. But GISAID also included a claim that has been puzzling and infuriating some virologists for 3 years: It was the place where the first SARS-CoV-2 genomes were publicly shared, on 10 January 2020. That claim challenges contempo...

He battled AIDS, COVID-19, and Trump. Now, Anthony Fauci is stepping down
Anthony Fauci, the renowned physician-scientist who has led the $6.3 billion National Institute of Allergy and Infectious Diseases (NIAID) for nearly 4 decades and since early 2020 has been the U.S. government’s voice of scientific reason during the COVID-19 pandemic, will step down from government service in December. Fauci, 81, had said in recent interviews that he planned to retire from the government by the end of President Joe Biden’s administration, but did not give a date until today. He said in a statement that although leading NIAID “has been the honor of a lifetime,” he plans to “pursue...

Mind the gap from research laboratory to clinic: Challenges and opportunities for next-generation assays in human diseases
Vaccine. 2021 Aug 5:S0264-410X(21)00964-6. doi: 10.1016/j.vaccine.2021.07.071. Online ahead of print.ABSTRACTModern vaccinology has experienced major conceptual and technological advances over the past 30 years. These include atomic-level structures driving immunogen design, new vaccine delivery methods, powerful adjuvants, and novel animal models. In addition, utilizing advanced assays to learn how the immune system senses a pathogen and orchestrates protective immunity has been critical in the design of effective vaccines and therapeutics. The National Institute of Allergy and Infectious Diseases of the National Institut...

How Convalescent Plasma Could Help Fight COVID-19
The last time most of us gave any thought to antibodies was probably in high school biology, but we’re getting a crash refresher course thanks to COVID-19. They are, after all, the key to our best defenses against SARS-CoV-2, the virus that’s caused the global pandemic. People who have been infected likely rely on antibodies to recover, and antibodies are what vaccines are designed to produce. Or at least that’s what infectious-disease and public-health experts assume for now. Because SARS-CoV-2 is such a new virus, even the world’s best authorities aren’t yet sure what it will take to build p...

Fight Aging! Newsletter, August 24th 2020
We report that electrical stimulation (ES) stimulation of post-stroke aged rats led to an improved functional recovery of spatial long-term memory (T-maze), but not on the rotating pole or the inclined plane, both tests requiring complex sensorimotor skills. Surprisingly, ES had a detrimental effect on the asymmetric sensorimotor deficit. Histologically, there was a robust increase in the number of doublecortin-positive cells in the dentate gyrus and SVZ of the infarcted hemisphere and the presence of a considerable number of neurons expressing tubulin beta III in the infarcted area. Among the genes that were unique...

Vaccines, Antibodies and Drug Libraries. The Possible COVID-19 Treatments Researchers Are Excited About
In early April, about four months after a new, highly infectious coronavirus was first identified in China, an international group of scientists reported encouraging results from a study of an experimental drug for treating the viral disease known as COVID-19. It was a small study, reported in the New England Journal of Medicine, but showed that remdesivir, an unapproved drug that was originally developed to fight Ebola, helped 68% of patients with severe breathing problems due to COVID-19 to improve; 60% of those who relied on a ventilator to breathe and took the drug were able to wean themselves off the machines after 18...
