WebSep 1, 2024 · At 3, 6, and 12 h after US-MB treatments, the structure of cytoplasmic fibrils interacting weakly with the desmosome of adjacent cells could be observed. These data suggest that US-MB damages the cell–cell junctions at sites of cell–cell contact and that their expression is dynamically regulated from 3 to 12 h after US sonication. WebThe truncated RRM2, as well as twoβ-strands within the RRM2, form fibrils in vitro with a similar amyloid-negative staining property to those of TDP-43 pathogenic fibrils in diseases. In addition to the glycine-rich region, the truncated RRM2, but not the intact RRM2, plays a key role in forming cytoplasmic inclusions in neuronal cells.
