TSPO immunohistochemical staining and Tspo-AcGFP formation in the neuroendocrine and endocrine systems. The pituitary gland (A, B, C; pd, pars distalis; pi, pars intermedia), pineal gland (D, E, F), thyroid gland (G, H, I; ep, epithelium, f, follicles), and adrenal gland (J, K, L; zg, zona glomerulosa; zf, zona fasciculata; zr, zona reticularis; m, medulla) were examined using H&E staining (A, D, G, J), TSPO immunostaining (B, E, H, K), and AcGFP presence detected by fluorescence microscopy (C, F, I, L)
