Figure 3. Effects of a prolonged application of NPY on the number of particles transported in neurites of cultured DRG cells.

Percentage changes in the number of transported particles of control (the value before application) in anterograde (○) and retrograde (•) directions induced by application of 1 μM NPY. Each point indicates the mean (± s.d.) of the values obtained from five DRG cells. * P < 0.05, ** P < 0.005, *** P < 0.0005 compared to the value before application.
