Using a humanized mouse model that mimics the effects of human rheuma-toid arthritis (RA), researchers have discovered that protein growth factors called cytokines in the immune system have both pro- and anti-inflammatory responses to RA that help explain why some patients respond to current therapy and others dont. By pinpointing the unique immune mecha-nisms involved in different forms of RA, the scientists hope to guide physicians toward more pre-cise individualized diagnosis of RA patients and more effective therapies that target specific forms of the disease.
The findings were published online on October 20 and are reported in the November issue of the Journal of Clinical Investigation. The research was conducted at the Lowance Center for Human Immunology at Emory University School of Medicine, and was led by rheumatologists Cornelia Weyand, MD, PhD, and Jorg Goronzy, MD, PhD. The studys first author was Thor-sten M. Seyler.
Rheumatoid arthritis (RA) is a chronic and crippling inflammatory joint, bone and cartilage disease affecting more than 2.1 million Americans. An autoimmune disease, RA is characterized by an abnormal immune response in which the immune system attacks healthy tissue, causing in-flammation of the lining of the joints, called the synovium.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
