New diagnostic procedure for fish allergy explored

Researchers at TU Vienna and FHI Berlin succeeded in monitoring a catalytic reaction with three different microscopies under exactly the same conditions in real time. In this way, information is obtained that none of the methods alone could reveal.

Although SARS-CoV-2 infections mainly attack the lungs, in many cases they can also damage other organs, such as the colon: around 60% of patients experienced digestive tract impacts. Researchers at MedUni Vienna have analysed the manifestations of Covid-19 in the lungs and colon and pinpointed the differences at a molecular level. Their findings, recently published in the "International Journal of Molecular Sciences", form the basis for the identification of novel biomarkers and the development of new treatment strategies.

Hitherto, scientists have not fully understood why ticks are such dangerous disease vectors. A research team led by Johanna Strobl and Georg Stary from MedUni Vienna's Department of Dermatology shows that tick saliva inhibits the skin's defence function, thereby increasing the risk of diseases such as tick-borne encephalitis (TBE) or Lyme disease. The study was recently published in the Journal of Clinical Investigation.

Anaplastic large cell lymphoma (ALCL) is an aggressive blood cancer that mainly affects children and adolescents, but it can also affect adults. A recent international study led by scientists from the Medical University Vienna and the Veterinary Medicine Vienna has now identified a new biomarker and effective therapeutic approach with the protein PDGFRβ and its downstream signaling pathway STAT3/5. According to the researchers, the inhibition of this axis promises a therapy with significantly improved prospects of success.
