Since the very beginning of the COVID-19 pandemic, in addition to the attempts to rapidly develop a vaccine that was effective against current strains, researchers have been looking for a vaccine that could protect more broadly against multiple coronaviruses.
There are 40 years of history behind the development of phosphoinositide 3-kinase (PI3K) inhibitors, Rebecca Dent told her audience at ESMO Breast Cancer 2022. And there have been success stories. There are five FDA-approved PI3K inhibitors in several cancer types, and in April, the FDA approved Vijoice (alpelisib; Novartis AG) for PIK3CA-related overgrowth spectrum, a rare disorder resulting from germline mutations of PIK3CA.
There is a project management joke that the first 90% of a project takes 90% of the time, whereas the last 10% of the project takes the other 90% of the time.
Researchers at Inserm have developed a method to direct pre-existing antibodies toward new targets. Their bimodular fusion proteins could be a broadly useful method for expanding access to antibody therapy. In a study that appeared in the Feb. 11, 2022, issue of Science Advances, the teams showed that antibodies to Epstein-Barr virus (EBV), which are present in 95% of the global population, could be redirected to a target cell of their choosing by fusing an EBV antigen to a cellular targeting ligand.
It is acknowledged that the huge bias toward individuals of European ancestry means studies of the contribution of genetics to disease may not translate well to other ethnicities. That point is underlined in the first large-scale investigation of the population structure and demographic history of British Pakistanis, which shows an increased number and length of regions of homozygosity inherited from a common ancestor, and greatly elevated identity by descent, compared to the population at large.
Immune system B cells secrete the neurotransmitter gamma amino-butyric acid (GABA), which promotes generation of anti-inflammatory macrophages and blunts the cytotoxic T cell-based response to tumors in mice.
PERTH, Australia – Australian researchers have debunked previous research that suggests autism spectrum disorder behavior may be caused by differences in the composition of the gut microbiota.
LONDON – Researchers have pinpointed a little-studied gene as responsible for doubling the risk of respiratory failure in COVID-19 and shown exactly how it exerts its effect. The gene, leucine zipper transcription factor like 1, is activated by a single base pair change on chromosome 3 that occurs in 60% of people of South Asian ancestry and 15% of people of European ancestry.
Investigators at Northwestern University’s Feinberg School of Medicine have used a new mouse model of Parkinson’s disease to confirm a causal role for mitochondrial dysfunction in Parkinson’s disease. More surprisingly, the same model has called into question previously uncontroversial notions about the motor features that are PD’s most conspicuous feature.
