Figure 4.
Two types of TDP-43-positive dystrophic neurites were evident in the frontal cortex of FTLD-U cases by immunohistochemistry. (A) Long neurites were frequent in the frontal cortex of 35% of FTLD-U cases (400X). (B) Dot-like neurites were frequent in an additional 14% of FTLD-U cases (400X). (C) The dot-like neurites were concentrated in layer II (arrows; 40X).
