Fig 1: Representative images of immunofluorescence staining. (A) Images of stained cells for DRD2 (green) and DRD1 (red). Blue color in the images represents fluorescence staining for cell nuclei with DAPI. (B-G) Similar images for (B) DRD3 (green) and DRD5 (red), (C) NF-L (green) and DRD4 (red), (D) SERT (green) and DAT (red), (E) TH (green) and TPH (red), (F) SYP (green) and 5HT1B (red), and (G) MAP2 (green) and 5HT1A (red).HF, Hizikia fusiformis extract treatment; VEH, vehicle treatment (control); DRD1-5, dopamine D1–5 receptors; DAT, dopamine transporter; DAPI, 4',6-diamidino-2-phenylindole; NF-L, neurofilament light chain; SERT, serotonin transporter; TH, tyrosine hydroxylase; TPH, tryptophan hydroxylase; SYP, synaptophysin; 5HT1A and 1B, serotonin 1A and 1B receptors; MAP2, microtubule-associated protein 2.
