Discovery opens doors to treating symptom that can cause the body to attack itself
Researchers at the University of Pennsylvania School of Medicine have identified a variant of the human gene for tumor necrosis factor-alpha (TNF-alpha) as the cause for photosensitivity in lupus patients. This discovery, which was presented today at the annual scientific meeting of the American College of Rheumatology, will not only help in treating photosensitivity, but will also advance research on treating this potentially damaging symptom and possibly point to one of the genetic causes of lupus.
Victoria Werth, MD Associate Professor of Dermatology and Medicine in Penn’s School of Medicine, working in collaboration with Kathleen E. Sullivan, MD, PhD, Associate Professor of Pediatrics, University of Pennsylvania School of Medicine, and attending physician in The Children’s Hospital of Philadelphia Division of Allergy and Immunology, identified a variant of the TNF-alpha promoter that showed increased activity when exposed to sunlight. This discovery is crucial to understanding photosensitivity and lupus because TNF-alpha has been shown to stimulate apoptosis, the process of cellular death. As skin cells die, intracellular proteins move to the cell’s surfaces where they stimulate an immune reaction. The immune system makes new antibodies against these proteins and triggers further inflammation, causing the body to attack its own internal organs - just from sunlight.

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....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

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...
