Possible noradrenergic regulation of IL-1β expression through β2-adrenoceptors (β2-ARs) activation within areas of the SDMN. (A–C’’) Immunofluorescent microphotographs of selected transverse sections showing colocalization of IL-1β with β2-ARs in (A–A’’) medial zone of the dorsal telencephalic area (Dm), (B–B’’) parvocellular preoptic nucleus, posterior part/magnocellular preoptic nucleus (PPp, PM), and (C–C’’) superior reticular formation (SRF). Arrows indicate examples of colocalization, dashed arrows point to single positive cells. Microphotographic images are representative of MK-801-treated fish, n = 5. Scale bar: 25 μm.
