biofilms destruct host membrane by mechanical stress The vast majority of bacteria in the world live on surfaces by forming structures called biofilms. These communities host thousands to millions of bacteria of different types, and are so biologically complex and active that scientists describe them as 'cities.' Biofilms are in fact the preferred lifestyle of bacteria. They form them by attaching to each other on surfaces as diverse as the ocean ..
how gut bacteria sticks to gut Researchers have revealed a new molecular mechanism by which bacteria adhere to cellulose fibers in the human gut. Thanks to two different binding modes, they can withstand the shear forces in the body. Cellulose is a major building block of plant cell walls, consisting of molecules linked together into solid fibers. For humans, cellulose is indigestible, and the majority of gut bacteria lack th..
oxygen therapy could affect lung microbiome One of the hallmarks of severe COVID-19 is shortness of breath and significantly reduced levels of oxygen in the blood, called hypoxemia. Upon hospitalization, these patients are administered oxygen in an attempt to bring their levels back up to normal. However, a new study hints that this universal therapy may have unintended consequences via an unexpected source—the microbiome. "It had been as..
new biomarker: enzyme in the gut Enzymes used by bacteria to break down mucus in the gut could provide a useful biomarker for intestinal diseases Researchers at the University of Birmingham and Newcastle University have successfully identified and characterized one of the key enzymes involved in this process. They demonstrated how the enzyme enables bacteria to break down and feed off sugars in the layers of mucus lining the gu..
bacteria와 virus의 interaction in gut "We're appreciating more and more that the most abundant microbial entities in the human gut are actually viruses," His team has been exploring the puzzling way bacteria and their viruses appear to coexist inside the human gut. The secret may lie in a hairy-looking sugar coating bacteria used to defend not only against attacks from the human immune system, but also from various viruses seeking a..
flotillin => membrane fluidity control protein In order to implement these properties, different types of proteins are active in cells, including the so-called flotillins. These proteins are present in cells from bacteria to humans. Until now, scientists assumed that these flotillins mainly help in the formation of other functional protein complexes and confine highly ordered areas of the cell membrane. researchers were able to show that flo..
statin과 microbiome의 관계 https://medicalxpress.com/news/2020-06-gut-microbiota-cholesterol-lowering-medication.html Scientists have previously found an association between the gut microbiota and various metabolism-related and cardiovascular diseases. Now the current study, published in the journal Nature, shows improvement in gut microbiota in the participant group who were taking statins.Scientists have previously foun..
