Lectin characterization of the olfactory system in brachiopterygian fish.
Lectin binding was performed on the olfactory system of Polypterus and Erpetoichthys, the living genera of the subclass of Brachiopterygii. The lectin histochemical patterns and the Western-blot analysis indicate that the receptor cells of the olfactory mucosa are characterized by high density of specific glycoconjugate residues. The presence of glycoproteins, whose terminal sugars are detected by lectin binding, might be related to the reception of an odor stimulus and its transduction into a nervous signal or to the histogenesis of the olfactory system.
