Aptameres for Treatment and Diagnosis of Diseases Seropositive for Autoantibodies


We offer the new application of the known thrombin aptamer Arc183– initially developed as a anticoagulant for thrombin inhibition – for the highly specific binding and neutralization of autoantibodies against G-protein coupled receptors (AAB) such as adrenergic alpha-1-, adrenergic beta-1- and beta-2 receptors, the endothelin 1 ETA receptor, the muscarinic M2 receptor, the angiotensin II AT1 receptor, and/or the PAR receptors. These AABs are not only present in defined cardiovascular diseases (e.g. idiopathic dilated cardiomyopathy, Chagas’ cardiomyopathy, peripartum cardiomyopathy, myocarditis, hypertension, pulmonary hypertension and malignant hypertension) but they are also present in other diseases, e.g. Chagas’ megacolon, Chagas’ megaoesophagus, Chagas’ neuropathy, glaucoma, diabetes mellitus, Alzheimer’s disease, benign prostatic hyperplasia, psoriasis, scleroderma, Raynauld’s syndrome and kidney allograft rejection. The pathogenetic function of the AABs is well documented, especially for cardiomyopathies and kidney rejection, and the removal of AABs by apheresis and treatments for AAB neutralization are under investigation. The aptamer strongly inhibits the agonistic effect of patients’ AABs via their detected function, as demonstrated in a bioassay that analysed the beating frequency of rat cardiomyocytes. The aptamer was also found to clear human serum of AABs when coupled to an apheresis column. <br><br> <b>Benefits:</b><ul> <li>Novel second medical indication for the thrombin aptamer Arc 183</li> <li>Possible therapeutic applications in diseases positive for AABs against G-protein coupled receptors </li>

Im Focus: ILA 2018: Laser alternative to hexavalent chromium coating

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...

Im Focus: Radar for navigation support from autonomous flying drones

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.

Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
