Sparse glial phospho-tau (p-tau) immunohistochemistry in Case 2. In this case, p-tau (PHF-1) immunoreactive structures were much more sparse, mostly non-neuronal, and were apparent in the medial temporal lobe. (a) In the hippocampus, p-tau immunostaining was found surrounding the rostral fringe of the inferior horn of the lateral ventricle (blue arrows; the ependymal lining denoted with an asterisk). Note that a few TSAs are stained (e.g., magenta arrow). (b) Shows p-tau immunoreactivity surrounding Virchow–Robin spaces of arterioles (blue arrow). Scattered p-tau + cells with delicate glial processes were also observed, such as that shown in (c) from the left-sided temporal cortex
