Figure 3. The purinergic receptors P2X7 and P2X4 are expressed at post-synaptic regions in hippocampal neurons.

Figure 3

Representative images showing the expression of P2X7 and P2X4 in hippocampal neurons. Co-localization of P2X7(A) and P2X4(B) with the neuronal marker MAP-2. Images to the right of each primary image are enlarged to show the indicated portion of the dendrite. MAP-2 (red) and P2X4 or P2X7 (green) appear as yellow in the merged images when co-localized with MAP-2. P2X7(C) and P2X4(D)(green) co-localize with the postsynaptic marker PSD-9 (red). P2X7(E) and P2X4(F) (green) do not co-localize with the presynaptic marker synaptophysin (red).
