How bacteria survive low oxygen environments

Researchers from ITQB NOVA, in collaboration with the Institut Pasteur in Paris, have shed light on the mechanisms that allow Clostridioides difficile, a pathogen that can only grow in oxygen-free environments, to be able ...

Stomach SIDT1 mediates dietary microRNA absorption

In a new study published in Cell Research, Chen-Yu Zhang's group at Nanjing University School of Life Sciences, China, reports that SIDT1 in the mammalian stomach mediates host uptake of dietary and orally administered microRNAs ...

Peptides that can be taken as a pill

Peptides are short chains of amino acids that occur in our body, in plants or bacteria to control diverse functions. Several peptides are used as drugs such as insulin, which controls the metabolism of sugar; and cyclosporine, ...
