Fig. 6. Cellular effects of SPANs are restricted to neuronal cells. Control CGNs (A) were compared with cells that were treated for 1 hour with taipoxin (B). Distribution of actin labelled with phalloidin (red) changed from filamentous structures to dots in intoxicated neurons, whereas the actin appearance of GFAP-positive astrocytes was unaltered (yellow). Scale bar, 50 µm.
