Chinese researchers are preparing the details for the publication of another scientific milestone, the creation of a chimera with a human heart and a kidney developed from human stem cells in pig embryos.

Researchers have identified KpsM as a virulence factor in Escherichia coli that was responsible for liver damage in alcohol-associated hepatitis (AH). A small-molecule inhibitor of KpsM reduced liver damage in animal models of AH.

Immunity is not a function most people particularly associate with the liver. But because of its connection to the gut, the liver is exposed to bacterial metabolites as few other organs are. And when either the liver or the gut is not functioning well, it can adversely affect immunity as well.

Planting seed money and “wishing” is not enough to claim “irreparable harm” to secure a preliminary injunction or to establish the standing required to appeal a patent board decision, the U.S. Court of Appeals for the Federal Circuit ruled May 7 in two decisions involving Incyte Corp. and Sun Pharmaceutical Industries Ltd.

Transplanting an animal organ into a human is now a closer reality following the successful xenotransplantation of a genetically modified pig liver into a patient diagnosed with brain death in China. The operation was intended to evaluate organ function over a 10-day period. This is a complex experimental trial that did not involve removing the patient's liver and still requires further study. However, the positive preclinical results suggest this strategy could save the lives of those waiting for a human organ, at least in certain cases.

Multisystem inflammatory syndrome in children (MIS-C), a serious disorder that develops after SARS-CoV-2 infection, could arise from latent infection of another pathogen, the Epstein-Barr virus (EBV). Researchers at Charité – Universitätsmedizin Berlin and the German Rheumatology Research Center (DRFZ) have linked the inflammatory effect of this co-infection with transforming growth factor β (TGF-β), ruling out the possibility that MIS-C is caused by an autoimmune reaction, or persistence of the coronavirus in the body.

In the first patenting from Lent Innovations LLC, the company’s founder, Anne Lent – an allergist and immunologist – describes their invention of an epinephrine auto-injector tailored to the specific needs of children to reduce the risk of use errors and incorrect injection technique.

The liver and pancreas are the main actors in glucose metabolism, but not the only ones. Muscles, adipose tissue and the brain play different roles. However, the prize for the best new actor in glucagon production goes to the innate lymphoid cells (ILCs), which, according to a study published in Science, respond to intestine neuron signals traveling to the pancreas to control glucose.

Our immune cells are not just “defenders” against deadly viruses and pathogens but also a great balancer for tissue homeostasis.

An international consortium of thousands of scientists is creating the Human Cell Atlas, a three-dimensional map of all the cells in the body. The goal is to understand all the cells that make up human tissues, organs and systems, which will enable multiple medical applications. This collection of cell maps is openly available for navigation at single-cell resolution, identified through omics analyses that reveal the tridimensional distribution of each cell.
