ApoE and the Brain


ApoE staining of neurons in normal brain

ApoE staining of plaques and tangles in AD brain.
*note the loss of apoE-immunopositive neurons.

Figure 1c. Glial staining (brown) in normal and AD brains. ApoE staining of amyloid plaques (blue) in AD brain, surrounded by inflamed glia.



ApoE and ApoE Receptors in the Brain

Figure 2. Although apoE is synthesized by glial cells, it is a secretory protein that is taken up by both neurons and glia via apoE receptors.



Role of ApoE in PNS Injury
