Abstract

The distribution of orexin‐A and orexin‐B immunoreactivity was examined in the pituitaries of the white‐spotted conger (Conger myriaster) and the Japanese eel (Anguilla japonica) using immunohistochemical techniques. Orexin‐A‐immunoreactive puncta were dispersed in the pars nervosa of the neurointermediate lobe, and a part of these puncta were immuno‐positive for galanin. In contrast, orexin‐B immunoreactive cells were observed in the proximal part of the pars distalis, and these cells were immuno‐positive for luteinizing hormone. Considering the present results and previous findings, orexin‐A and orexin‐B may modulate the secretion of α‐melanocyte‐stimulating hormone and growth hormone, respectively, and participate in the regulation of energy homeostasis.
