In addition, the immunostaining highlighted cells with short processes stemming from the round perikaryon in a spoke wheel-like fashion (Figure 3, panel D).
We also assessed the expression and localization of mOatp1b2 in neurons via immunocytochemistry, which revealed immunopositive staining in membranes of the perikaryon as well as in neurites of cultured cells (Figure 4G).
Al induced tangles are found in the perikaryon and proximal parts of the dendrites and axon (50,51).
