Reelin (IMAGE) Picower Institute at MIT Caption Researchers compared Reelin expression in excitatory neurons in the entorhinal cortex of people with (right) or without (left) Alzheimer’s disease. In people without the disease, vGlut (green), a marker of excitatory neurons, and Reelin (magenta) were often expressed together. In people with Alzheimer’s, excitatory cells exhibited much less Reelin expression.
