L-DOPA Uptake in Astrocytic Endfeet Enwrapping Blood Vessels in Rat Brain

Figure 3

Double staining of hippocampal brain slice with L-DOPA and ASP⁺ (fluorescent substrate for transporters present in astrocytes and some other cells). Uptake revealed with the Falck-Hillarp method (see. Section 2). Astrocytes take up both L-DOPA and ASP⁺ (indicated with arrows). Scale: 20 μm.
