Witryna1 lut 2016 · Upon formation of an immunological synapse, the MTOC in DCs can reorient towards the T cell and this remodeling is mediated by the GTPase Cdc42 (87). MIIC tubules and other compartments of endosomal nature move over microtubules (84, 93, 94, 96), although MHC class II recruitment via actin has also been reported (97). ... Witryna17 cze 2024 · The TcEs were tested in CD8+ T-cell killing of Her2+ breast cancer cells and evaluated by high-content imaging of immunological synapse formation on a supported lipid bilayer (SLB) platform. We find that cis TcEs perform better than a trans TcE for T-cell mediated killing. Quantification of synapse formation dynamics …
