Japanese researchers have transplanted human induced pluripotent stem cells (iPSCs) in a primate model of myocardial infarction and were able to restore heart muscle and function in monkeys. Developed by Tokyo-based Heartseed Inc., the grafted iPSCs consist of clusters of purified heart muscle cells (cardiomyocyte spheroids) that are injected into the myocardial layer of the heart. Published in Circulation on April 26, 2024, the study showed that the cardiomyocyte spheroids survived long term and showed improved contractile function with low occurrence of post-transplant arrhythmias.
In one of the biggest startups ever, Xaira Therapeutics has launched with more than $1 billion from investors. The financing, according to BioWorld records, is roughly equivalent to Roivant Sciences Inc.’s $1.1 billion raise in August 2017 and Galderma Inc.’s $1 billion private placement in June 2023.
Deep learning algorithms have enabled the discovery of molecular structures of interest in biomedicine to design treatments against aggressive diseases such as idiopathic pulmonary fibrosis (IPF). Scientists at Insilico Medicine Inc. selected a target for IPF using artificial intelligence (AI), then designed an inhibitor to block it, and tested it in vitro, in vivo, and in clinical trials.
Since its founding by the National Institutes of Health (NIH), the scientists of the All of Us Research Program have set the goal to analyze the largest diversity of the genomic population in the country and end the under-representation of its different groups. The project has expanded the vision of several pathologies, discovered thousands of new genetic variants, redefined the risk genes for common diseases, and stratified them, uncovering eight different forms in the case of type 2 diabetes (T2D). Their results create a pathway for a new age of precision medicine.
Immunoglobulin G (IgG), an antibody that participates in the response to infection, could have a specific role in metabolism. During aging, it accumulates in certain tissues inducing metabolic dysfunction and fibrosis of fat tissue. This effect could be prevented through an intracellular receptor that contributes to the delivery of IgG. A team of researchers from Columbia University and Peking University (PKU) demonstrated that reducing excess IgG improved the metabolic health of aged mice and increased their life expectancy.
