Cortical mouse neurons at 7 days in vitro 7 (DIV7) are well polarized with a single, long, branched axon and shorter dendrites arising from the cell body. The cortical neurons were cultured from E17 m...

Exposure of a cortical neuron to netrin induces the phosphorylation of focal adhesion kinase (FAK) at Tyr397 along the axon and within the growth cone (gc). Insert shows the control neuron (without tr...

Toll-like receptor 9 (TLR9, red) expression in the hippocampus of the adult mouse brain. Notably, TLR9 stains selectively the mossy fibers (indicated by arrowheads) but not other axonal pathways in th...

Immunohistochemistry of neuron-specific β-III-tubulin (red) shows the delicate dendrites of Purkinje cells in the cerebellum. Cell nuclei are revealed with DAPI staining (blue). Scale bar, 100 µm.
