The gene was localized using cutting edge technologies for examining the whole human genome at the Helmholtz Zentrum München.
The newly discovered FCER1A gene encodes the alpha chain of high affinity IgE receptor, which plays a major role in controlling allergic responses. The team of scientists led by Dr. Stephan Weidinger from the Technische Universität München and Dr. Thomas Illig from the Helmholtz Zentrum München found that certain variations of the FCER1A gene decisively influence the production of immunoglobulin E (IgE) antibodies.
IgE antibodies are a particular type of antibody that is normally used to protect against parasites. In Western lifestyle countries with less contact, however, elevated IgE levels are associated with allergic disorders.
In genetically susceptible individuals the immune system becomes biased and produces IgE antibodies against harmless agents such as pollen, dust mites or animal hair. These IgE antibodies then work in conjunction with certain cells to get rid of the allergens, a process that gives rise to the symptoms of allergy such as allergic rhinitis (hay fever), atopic dermatitis or asthma.
“Most people with allergies are atopic - meaning they have a genetic tendency to develop allergies. To detect the genetic factors we examined the genomes of more than 10,000 adults and children from the whole of Germany" explained Stephan Weidinger.
Most of the persons examined for the study come from the population studies of the KORA (co-operative health research in the Augsburg region) research platform, which is led by Prof. Dr. H.-Erich Wichmann, the Director of the Institute of Epidemiology at the Helmholtz Zentrum München. The allergological examinations were carried by the Department for Dermatology and Allergy of the Technische Universität München headed by Prof. Dr. Dr. Johannes Ring.
Although in its early stages, the new knowledge on the regulation of IgE production does have the potential to guide the development of new drugs.

From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components. The method which has reached Technology Readiness Level 6 already, is currently being successfully tested in practical use together with a number of industrial partners.
Reducing machine downtime, manufacturing defects, and excessive scrap
The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
