Highlights • Gut microbes show a dichotomy in ecological strategy for access to nitrogen • Beneficial microbes are overrepresented in the endogenous N source guild • Diets that reduce availability of dietary N to microbes promote healthy aging • Diet impact on host-microbiome interaction can be simplified for modeling

Scientists are one step closer to understanding the link between different diet strategies and gut health, with new research presenting the first general principles for how diet impacts the microbiota. Researchers from the University of Sydney have found that the availability of intestinal nitrogen to microbes in the gut plays a key role in regulating interactions between gut microbes and their host animal.

“This research really lays the groundwork for future modellin...

Reparative Effects of Interleukin-1 Receptor Antagonist in Young And Aged/Co-Morbid Rodents After Cerebral Ischemia. Brain, Behavior, and Immunity, 2016; DOI: 10.1016/j.bbi.2016.11.013

A potential new drug reduces the number of brain cells destroyed by stroke and then helps to repair the damage. A reduction in blood flow to the brain caused by stroke is a major cause of death and disability, and there are few effective treatments. A team of scientists at The University of Manchester has now found that a potential new stroke drug not only works in rodents by limiting the death of existing brain cells but also by promoting neurogenesis.

This finding provides further support for the development of this anti-inflammatory drug, interleukin-1 receptor antagonist (IL-1Ra in short), as a new treat...

A naturally occurring predatory bacterium is able to work with the immune system to clear multi-drug resistant Shigella infections in zebrafish. It is the first time the predatory bacterium Bdellovibrio bacteriovorus has been successfully used as an injected anti-bacterial therapy and represents an important step in the fight against drug-resistant infections, or ‘superbugs’.

Shigella infection is responsible for over 160 million illnesses and over 1 million deaths every year – and is a common cause of ‘trave...

Synovial Fibroblasts (SFs)  are cells that make up part of the connective tissue, or synovium, around human joints. In RA patients, SF cells cause damage by invading and attacking the cartilage and bone around the joint

A study reveals the key role of different types of fibroblast cells in the development of rheumatoid arthritis (RA), opening up a new avenue for research into treatment of the disease. Synovial Fibroblasts (SFs) are cells that make up part of the connective tissue, or synovium, around human joints. In RA patients, SF cells cause damage by invading and attacking the cartilage and bone around the joint.

A team from University of Birmingham’s Institute of Inflammation and Ageing identified 2 distinct types of SF within the synovial membrane...
