Fig. 2.
Colocalization of PKCα and TH-IR. a: Certain amacrine cells (arrows) at the border of inl/ipl show PKCα-IR (green) but not tyrosine hydroxylase (TH)-IR (red). A few TH-IR processes running in the distal most sublamina of the ipl are visible. In b, the cell body of a large TH-IR neuron is visible. c: The same neuron (asterisk) shows weak PKCα-IR, whereas adjacent amacrines not showing TH-IR (arrows) have pronounced PKCα-IR. Scale bar = 20 µm for a–c.
