FIGURE 12.
Tau aggregates localize to endosomal compartments. HeLa cells were processed for ultrathin cryosectioning and immunogold labeled for Tau (PAG 5 nm; A, C, and D) or double immunogold labeled for Tau (PAG 5 nm, arrows) and Lamp1 (PAG 10 nm; B, E, and F). Tau aggregates were observed in multivesicular bodies (MVB), small vesicles (A)(Ves, arrowheads), and lysosomes (B)(Lys). Scale bar represents 250 nm.
