Adhesion experiments and analysis of the human pathogen Acanthamoeba castellanii

Published on November 6, 2015

The ubiquitous human pathogenic Acanthamoeba castellanii can cause severe brain or eye infections like Acanthamoeba keratitis (A. keratitis), which occurs mainly due to wrong contact lens use and can lead to complete vision loss. For immune suppressive individuals it can even cause a granulomatous amoebic encephalitis (GAE). Therefore, research on soft polymers comparable to contact lenses are carried out to investigate the pathogenicity of these amoebae and to develop strategies for avoiding infections with these parasites.

Prof. Dr. rer. nat. Christine Selhuber-Unkel is head of the group Biocompatible Nanomaterials at the Christian Albrechts-University of Kiel. She and her group study dynamic processes in cells to gain further insight into the interplay of intracellular and extracellular phenomena. A particular focus is in cellular mechanotransduction studies and in transferring such cellular mechanotransduction concepts into novel biomimetic materials.
