If immunoglobulin E (IgE) antibodies are directed against harmless antigens such as pollen, the result can be an allergic reaction. However the original purpose of these IgE antibodies is to repel harmful exogenous substances rather than to trigger allergies. In collaboration with Vetmeduni Vienna and international scientists, researchers from MedUni Vienna have now made use this function: they have developed a "canine IgE" that directly targets the EGFR growth factor in cancerous tumours. The main finding: in-vitro studies showed that the tumour was destroyed by the IgE antibodies in more than 60% of cases.
The response of endogenous immunoglobulin E that leads to the development of allergies is "pointless", because it interacts with inflammatory cells to turn against harmless antigens , thereby causing serious allergies.
"Our motto in the current study is: Is there any point to IgE?" says its lead author, Erika Jensen-Jarolim, who has dual affiliation, both to MedUni Vienna's Institute of Pathophysiology and Allergy Research and to the inter-university Messerli Research Institute of the University of Veterinary Medicine Vienna, Medical University of Vienna and University of Vienna.
"Using dogs as ' model patients’, we were able to show that tumours that have the EGFR growth factor can be killed by immunoglobulin E, irrespective of the breed of dog," explains Jensen-Jarolim. By the way, the 3rd of June is "Day of the Dog".
The results of the study, which have now been published in leading magazine "Journal of Allergy and Clinical Immunology" (JACI), are also highly promising, since canine EGFR is a 92% match for human EGFR. IgE antibodies build a "bridge", as it were, between the EGFR on cancer cells and the inflammatory cells, thereby releasing tumour necrosis factors – which immediately start to kill the tumours.
Says Jensen-Jarolim: "We can therefore hope that we have made an important contribution towards developing a new form of immunotherapy against cancerous tumours. A subsequent clinical trial will be conducted in canine patients to validate the results in an international joint initiative before moving to human trials. "This paper is a perfect example of what we are all about at the Messerli Research Institute: improving medicine for people but for animals as well."

Medical University Vienna - short profile
Medical University Vienna (MedUni Vienna) is one of the most traditional medical education and research facilities in Europe. With almost 8,000 students, it is currently the largest medical training centre in the German-speaking countries. With 5,500 employees, 26 departments and three clinical institutes, 12 medical theory centres and numerous highly specialised laboratories, it is also one of Europe's leading research establishments in the biomedical sector.
About Messerli Research Institute
The Messerli Research Institute was founded in 2010 with support from the Messerli Foundation (Sörenberg, Switzerland) under the management of the University of Veterinary Medicine, Vienna in cooperation with the Medical University of Vienna and the University of Vienna. The research is devoted to the interaction between humans and animals, as well as its theoretical principles in animal cognition and behavior, comparative medicine and ethics. Its work is characterized by its broad interdisciplinary approach (biology, human medicine, veterinary medicine, philosophy, psychology, law) and strong international focus. http://www.vetmeduni.ac.at/en/messerli/

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
