The level of Aβ₄₀ and Aβ₄₂ in the brain sections of experimental mice studied by immunohistochemistry.

<p>Confocal microscopy images of the hippocampus CA1 or motor/somatosensory cortex of non-treated (Ctrl), α7(1–208)-immunized or LPS-injected mice stained with biotinylated Aβ₄₀- or Aβ₄₂-specific antibodies and developed with Extravidin-Cy3 (<i>red</i>) and with α7-specific antibody developed with anti-rabbit Alexa 488 (<i>green</i>). Bar corresponds to 50μm, actual for each fragment of the panel.
