    • CellSegm - a MATLAB toolbox for high-throughput 3D cell segmentation 

      Hodneland, Erlend; Kögel, Tanja; Frei, Dominik M.; Gerdes, Hans-Hermann; Lundervold, Arvid (Peer reviewed; Journal article, 2013-08-09)
      The application of fluorescence microscopy in cell biology often generates a huge amount of imaging data. Automated whole cell segmentation of such data enables the detection and analysis of individual cells, where a manual ...

    • Efficient extraction of small microplastic particles from rat feed and feces for quantification 

      Toto, Benuarda; Refosco, Alice; Dierkes, Jutta; Kögel, Tanja (Journal article; Peer reviewed, 2023)
      To date, microplastic is ubiquitously encountered in the environment. Studies analyzing microplastic in terrestrial ecosystems, including animal feces and feed, are few. Microplastic quantification method validation and ...

    • Intestinal permeability and gene expression after polyethylene and polyamide microplastic ingestion in Wistar rats 

      Toto, Benuarda; Refosco, Alice; O'Keeffe, Maria; Barkhald, Øyvind Halås; Brønstad, Aurora Margrethe; Lied, Gülen Arslan; Yadetie, Fekadu; Goksøyr, Anders; Kögel, Tanja; Dierkes, Jutta (Journal article; Peer reviewed, 2022)
      Microplastic particles are ubiquitous in the environment. However, little is known about their uptake and effects in humans or mammalian model organisms. Here, we studied the effects of pristine polyamide (15–20 µm) and ...

    • Novel microscopy-based screening method reveals regulators of contact-dependent intercellular transfer 

      Frei, Dominik Michael; Hodneland, Erlend; Rios-Mondragon, Ivan; Burtey, Anne Pierrette; Neumann, B; Bulkescher, Jutta; Schölermann, Julia; Pepperkok, Rainer; Gerdes, Hans-Hermann; Kögel, Tanja (Peer reviewed; Journal article, 2015-08-14)
      Contact-dependent intercellular transfer (codeIT) of cellular constituents can have functional consequences for recipient cells, such as enhanced survival and drug resistance. Pathogenic viruses, prions and bacteria can ...

    • Roles of Myosin Va and Rab3D in Membrane Remodeling of Immature Secretory Granules 

      Kögel, Tanja; Gerdes, Hans-Hermann (Peer reviewed; Journal article, 2010-12-22)
      Neuroendocrine secretory granules (SGs) are formed at the trans-Golgi network (TGN) as immature intermediates. In PC12 cells, these immature SGs (ISGs) are transported within seconds to the cell cortex, where they move ...
