The skinny on lipid immunology
Phospholipids - fat molecules that form the membranes found around cells - make up almost half of the dry weight of cells, but when it comes to autoimmune diseases, their role has largely been overlooked. Recent research has pointed to a role for them in numerous diseases, including psoriasis, contact hypersensitivities and allergies. In a new study published in Science Immunology, researchers from Brigham and Women's Hospital and Monash University in Australia reveal new insights into the basis for T cell receptor (TCR) autoreactivity to self-phospholipids, with implications for autoimmune diseases.

The booklet seems to have had a significant effect, according to new research from the University of Copenhagen. After the guidelines were introduced, the number of stillbirths at the hospital fell by 33 per cent. The study reveals an opportunity to customise clinical guidelines more effectively to low-income countries, according to the researchers.

How obesity promotes breast cancer
Obesity leads to the release of cytokines into the bloodstream which impact the metabolism of breast cancer cells, making them more aggressive as a result. Scientists from Helmholtz Zentrum München, Technische Universität München (TUM), and Heidelberg University Hospital report on this in Cell Metabolism. The team has already been able to halt this mechanism with an antibody treatment.

Physical inactivity and restless sleep exacerbate genetic risk of obesity
Low levels of physical activity and inefficient sleep patterns intensify the effects of genetic risk factors for obesity, according to results of a large-scale study presented at the American Society of Human Genetics (ASHG) 2017 Annual Meeting in Orlando, Fla. These results confirm and strengthen previous findings based on self-reported activity.

'Antelope perfume' keeps flies away from cows
In Africa, tsetse flies transfer sleeping sickness to cattle. This leads to huge losses in milk, meat and manpower. The damage in Africa is estimated to be about $4.6 billion U.S. each year. Prof. Dr. Christian Borgemeister from the Center for Development Research (ZEF) at the University of Bonn and his colleagues from Kenya and the UK have developed an innovative way of preventing the disease. The scientists took advantage of the fact that tsetse flies avoid waterbucks, a widespread antelope species in Africa. The scientists imitated the smell of these antelopes. Eighty percent of cattle equipped with collars containing the defense agent were spared from the infection. This research results are presented in PLOS Neglected Tropical Diseases.

Evidence found of oral bacteria contributing to bowel disorders
(Medical Xpress)—An international team of researchers has found evidence that suggests certain types of oral bacteria may cause or exacerbate bowel disorders. In their paper published in the journal Science, the group describes testing the impact of introducing bacteria found in the mouths of humans to mice models. Xuetao Cao with the Chinese Academy of Medical Sciences offers a Perspective piece on the work done by the team in the same journal issue and suggests that the work might one day lead to the development of new kinds of treatments for common bowel disorders.

Bacterial pathogens outwit host immune defences via stealth mechanisms
Despite their relatively small genome in comparison to other bacteria, mycoplasmas can cause persistent and often difficult-to-treat infections in humans and animals. An extensive study by researchers from Vetmeduni Vienna has now shown how mycoplasmas escape the immune response despite their minimal "genetic arsenal". Mycoplasmas vary their surface as needed by switching from one gene variant to an alternative when the first is recognized by the immune system: Mycoplasmas "mask" themselves. They use their small genome in such a clever strategic way that they can even compensate for the loss of an enzyme that is important for this process. This could be shown for the first time in vivo in a living host organism, thus representing a breakthrough in the research of this special group of bacterial pathogens. The study was published in PLOS Pathogens.
