Double immunofluorescence of cells expressing GRα-ir co-localized with the β₂-ARs in zebrafish brains. Double-labeled cells were found in (A–C) the medial zone of the dorsal telencephalic area, Dm; (D–F) the anterior part of the parvocellular preoptic nucleus, PPa; (G–I) the posterior part of the parvocellular preoptic nucleus, PPp; (J–L) the ventral zone of periventricular hypothalamus, Hv; and (M–O) the locus coeruleus, LC. The left column depicts the glucocorticoid GRα expression in green, the middle column depicts the expression of the β₂-AR ir with red, the third column depicts the co-localization of β₂-ARs with GRα, shown more precisely in inserts of higher magnification. Scale bar = 0.05 mm.
