Characteristics of Tau fibrils trafficking in TNTs. For (a) and (b), cells were infected with LVs encoding GFP-Actin (red). At 48 h post-infection, cells were incubated for six hours with 1 μM ATTO 568-hTau1N4R fibrils (green). a The speed of Tau fibrils in TNTs in CAD neuronal cells was calculated from 17 independent videos. b Co-localization analysis between Tau fibrils and actin in TNTs. Significant positive correlation was found between Tau fibrils and actin (Pearson correlation coefficient: 0.727). For (a) and (b), cells were filmed with an inverted spinning disk microscope using a 63× oil-immersion lens (NA 1.4) and processed with ZEN blue and ImageJ software. A focal plane was collected for each specimen Scale bar: 10 μm
