For cellular localization, we have examined postmortem DS, AD and control brain tissues (n = 10 in each group) by immunohistochemistry and analyzed by bright field or confocal microscopy, using TREM2, tau (t-Tau and p-Tau), Aβ40, Aβ42, and ApoE antibodies. The gene discussed is MAPT; the disease is Dravet syndrome.
