On the trail of active ingredients from marine yeasts

Added: 23.01.2021 19:18 | 16 views | 0 comments

Numerous natural products are awaiting discovery in all kinds of natural habitats. Especially microorganisms such as bacteria or fungi are able to produce diverse natural products with high biomedical application potential in particular as antibiotics and anticancer agents. Researchers have isolated red yeast of the species Rhodotorula mucilaginosa from a deep-sea sediment sample and analyzed for its genome and chemical constituents. The scientists succeeded in demonstrating its anticancer and antibacterial effects.

Message in a bottle: Info-rich bubbles respond to antibiotics

Added: 22.01.2021 20:18 | 25 views | 0 comments

Researchers describe the effects of antibiotics on membrane vesicles, demonstrating that such drugs actively modify the properties of vesicle transport. Under the influence of antibiotics, MVs were produced and released by bacteria in greater abundance and traveled faster and further from their origin. The work sheds new light on these important information-carrying entities, implicated in many cellular communication processes, including antibiotic resistance.

Molecules that reduce 'bad' gut bacteria reverse narrowing of arteries in animal study

Added: 22.01.2021 5:18 | 5 views | 0 comments

Scientists have developed molecules that can remodel the bacterial population of intestines to a healthier state. They also have shown -- through experiments in mice -- that this approach reduces cholesterol levels and strongly inhibits the thickened-artery condition known as atherosclerosis.

Cholesterol lowering drugs linked to improved gut bacteria composition in obese people

Added: 22.01.2021 5:18 | 6 views | 0 comments

Obese Europeans who are treated with cholesterol lowering drugs have not only lower values of blood LDL cholesterol and markers of inflammation but in addition a more healthy gut bacteria profile than those obese who are not prescribed statins.

Vulnerable cells armor themselves against infection by depleting surface cholesterol

Added: 22.01.2021 5:18 | 4 views | 0 comments

Cells in some of the body's most vulnerable entry routes to bacterial infection buffer themselves when the immune system detects danger by reorganizing the cholesterol on their surfaces, a new study suggests.

An atlas of S. pneumoniae and host gene expression during colonization and disease

Added: 22.01.2021 4:19 | 5 views | 0 comments

The bacteria Streptococcus pneumoniae colonizes the nasopharynx and can cause pneumonia. Then, it can spread to the bloodstream and cause organ damage. To understand how this pathogen adapts to different locations in the body, and also how the host responds to the microbe, researchers have measured bacterial and host gene expression at five different sites in a mouse model -- the nasopharynx, lungs, blood, heart and kidneys -- using three genetically different strains of S. pneumoniae.

How the skin becomes inflamed: Toxin-producing bacteria

Added: 21.01.2021 23:20 | 6 views | 0 comments

Researchers report the discovery of a key underlying immune mechanism that explains why to how our skin becomes inflamed from conditions such as atopic dermatitis, more commonly known as eczema. Toxin-producing bacteria on the surface of our skin induces a protein that causes our own cells to react and cause inflammation.

Skin bacteria could protect against disease

Added: 21.01.2021 23:20 | 4 views | 0 comments

There are more and more examples of the ways in which we can benefit from our bacteria. According to new research, this is true for the skin as well. The work has shown that the most common bacteria on human skin secrete a protein which protects us from the reactive oxygen species thought to contribute to several skin diseases. The protein has an equally strong effect on dangerous oxygen species as known antioxidants such as vitamin C and vitamin E.
