Highlights •MYSM1 inhibits PRR pathways for pro-inflammatory and type I IFN gene induction •MYSM1 transiently accumulates in the cytoplasm upon microbial challenge •MYSM1 interacts with and inactivates TRAF3 and TRAF6 via its SWIRM and MPN domains •MYSM1 protects against sepsis but renders mice more susceptible to viral infection

Our immune system is vital to us and can sometimes overreact causing chronic illnesses, such as for instance rheumatism and allergy. Now, researchers have identified a molecular switch – MYSM1 – that can suppress such an overreaction and avoid inflammation.

“The discovery of MYSM1 is a major milestone in our understanding of how our immune system works, and how its response could be controlled in order to prevent inflammatory diseases such as sepsis,” ...

New OCT tool to study how diseases like dementia, Alzheimer’s, and brain tumors change brain tissue over time. “In the brain, the imaging depth is almost doubled,” said Martin Leahy of the National University of Ireland, Galway. “The authors demonstrate for the first time an application in which this capability opens up a whole new window into the live intact hippocampus, for discovery in brain research.”

From the experimental findings, the authors envision that this new optical coherence tomography (OCT) approach to brain study may enable examination of acute and chronic morphological or functional vascular changes in the deep brain, which has been rarely attempted before in the OCT community.

In Feb 2015, the photo of a striped dress stirred a worldwide internet debate ; now, neuroscientists have further decoded the phenomenon, demonstrating optical illusion is linked to specific brain activation patterns.

For some, it is black-blue, for others, it is white-gold. In a fMRI study, the neuroplasticity group headed by Prof. T. Schmidt-Wilcke solved the riddle of the illusion. In no time at all, the dress had captured the attention of media and scientists worldwide. Many research institutes have explored the phenomenon from various angles, by analyzing psychophysics or details of the image components...

Aspirin’s active form, salicylic acid, blocks a protein called HMGB1, which triggers inflammation in damaged tissues. The new findings may explain the disease-preventing effects of a low-dose aspirin regimen and offer hope that more effective aspirin-like drugs may be developed for a wide variety of diseases.

“We’ve identified what we believe is a key target of aspirin’s active form in the body, salicylic acid, which is responsible for some of the many therapeutic effects that aspirin has...
