Patients with cystic fibrosis show wide variability both in terms of the inflammatory burden of the lung and in their response to inhaled glucorticoids. As such, the effectiveness of this therapy in patients with cystic fibrosis remains uncertain. However, previous research has suggested that specific subgroups of patients may benefit from treatment with inhaled glucocorticoids.
In several inflammatory diseases, variations in sensitivity to glucocorticoids have been found to be associated with single nucleotide polymorphisms in the glucocorticoid receptor gene. So, a team from Hôpital Trousseau, Assistance Publique Hôpitaux de Paris, Inserm and Université Pierre et Marie Curie (all based in Paris, France) set out to investigate the effect of four polymorphisms (TthIII, ER22/23EK, N363S and BclI) in the glucocorticoid receptor gene on disease progression in 255 young people with cystic fibrosis.
The BclI glucocorticoid receptor gene polymorphism was found to be significantly associated with a decline in lung function, as measured by the forced expiratory volume in 1 second and the forced vital capacity. The deterioration in lung function was more pronounced in patients with the BclI GG genotype than in those with the CG and CC genotypes.
The authors write: "The association of BclI polymorphism and lung disease progression in cystic fibrosis gives support to the concept that specific subgroups of patients with cystic fibrosis may benefit from the use of glucocorticoids preferably by the inhaled route. If true, this should allow discriminatory prescribing which is of tremendous importance."

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...
