To overcome the lack of suitable in vitro models that faithfully recapitulate the intricate three-dimensional architecture, complex cellular interactions, and fluid dynamics within the SAS, we have developed a perfusion bioreactor-based 3D in vitro model using primary human meningothelial cells (MECs) to generate meningeal tissue constructs.

Further, we analyse what role that the cellular changes to the plant, and the plant genes doing it, have for the ability of plants to be promoted by growth- and protection-promoting fungi. (lu.se)

Their selective effect on Aβ proteotoxicity was further reflected by a reduction of Aβ aggregation, as assessed using the Aβ-specific fluorescent probe NIAD 4. (uni-giessen.de)
Knockdown of hsf-1, an ortholog essential for the cytosolic heat shock response, abolished the reduction of Aβ aggregation and proteotoxicity by 4-PBA incubation. (uni-giessen.de)
