title: Immunocytochemical localization of prolactin-like antigenic determinants in the neuroendocrine system of the honeybee (Apis mellifica).
abstract: In the brain of the adult worker bee (Apis mellifica) prolactin-like (PRL) immunoreactive cells were localized in the lateral neurosecretory cell region and the subesophageal ganglion by means of the PAP procedure. These cells emit nerve fibers which pass through the neuropile of the brain to the corpora cardiaca where a great number of immunoreactive axon terminals is present. Test with antisera against rat pituitary prolactin and human luteinizing hormone were negative. These results indicate that hPRL material is produced in neurosecretory cells of the bee brain and transferred via axons to the corpora cardiaca for storage and subsequent release into haemolymph.
