Role of diet and gut microbiome in the major depressive disorder

An international group of researchers headed by André Carvalho has published in Psychotherapy and Psychosomatic a paper that provides new data and prospects for the links between the intestinal flora and several disorders, notably depression. Persistent low-grade immune-inflammatory processes, oxidative and nitrosative stress and hypothalamic-pituitary-adrenal axis activation are integral to the pathophysiology of the major …

Research unveils structure of crucial bacterial cell wall protein

Duke University researchers have provided the first close-up glimpse of a protein, called MurJ, which is crucial for building the bacterial cell wall and protecting it from outside attack. The research is published in Nature Structural and Molecular Biology. Researchers at Duke University solved the structure of an enzyme that is crucial for helping bacteria …

Modified bacterial genes used to boost electrical conductivity in human cells

(Durham) Duke University biomedical engineers have harvested genes for ion channels from bacteria that, with a few tweaks, can create and enhance electrical signaling in human cells, making the cells more electrically excitable. The technique could one day be used to treat cardiac arrhythmia or to restore electrical functions to scarred heart or nervous system tissues. …
