Autoantibodies (autoAB) against the insulin receptor (IR) are known to cause a rare form of diabetes, i.e. insulin resistance type B. AutoAB against the structurally and functionally related receptor for insulin-like growth factor-1 (IGF1R) have only recently been described and are implicated in autoimmune diseases. However, the prevalence and clinical importance of these autoAB are not yet fully understood as respective sensitive and non-radioactive test systems for routine use were missing. A reliable assay system for the detection and quantification of these autoAB should be met with highest interest by basic researchers and clinicians alike, especially in the fields of diabetes, growth and cancer research, given the central importance of the insulin and IGF1 hormone axes for controlling growth, glucose metabolism and cell proliferation in humans.<br><br> <strong>Technology</strong><br> Two novel non-radioactive and highly sensitive immunoassays for detection and quantification of autoAB against the IR and IGF1R have been developed. For reasons of sensitivity, specificity and automation, the bridge technology has been chosen as most suitable assay format (see scheme). Using these novel in vitro diagnostica, autoAB against the IR and the IGF1R are detected with an astonishing 10% prevalence in the adult population. Notably, a high proportion of cross-reacting autoAB are found, reacting with similar strength to both the IR and IGF1R. The clinical and diagnostic importance of these results remains to be established in ongoing studies.<br><br>

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
