Horseradish peroxidase-conjugated lectins were used on tissue sections to localize the main secretory glycoproteins in cat submandibular glands and on Western blots to evaluate their movement into saliva with selective nerve stimulation. Central acinar cells bound lectins from Arachis hypogaea (PNA) specific for the terminal disaccharide Gal beta 1, 3GalNac, Griffonia simplifolia (GSA I-B4) specific for terminal alpha Gal, and Lotus tetragonolobus (LTA) specific for fucose. Lectins from Limax flavus (LFA) specific for sialic acid and Dolichos biflorus (DBA) specific for terminal alpha GalNac reacted preferentially with demilunar cells, whereas apical granules in striated ducts were recognized principally by LTA. Parasympathetic stimulation promoted the release of lectin-reactive glycoconjugates from both central and demilunar cells. In contrast, sympathetic stimulation caused almost complete release of LTA-reactive granules in striated ducts and only moderate secretion from demilunar cells. Lectin blots of stimulated saliva discriminated many of the constituent bands, providing information about their glycosylation. Several bands were common to both parasympathetic and sympathetic saliva, and many bands gave wider ranges of lectin binding than anticipated from the histochemistry. The major component in parasympathetic saliva was a glycoconjugate of less than 12 KD which reacted with every lectin tested. Lectin blots of sympathetic saliva showed a prominent diffuse LTA-reactive band around 33 KD, which was attributed to tissue kallikrein. The identity and cellular origin of most bands in stimulated submandibular saliva are still unclear but the technique shows considerable promise for improving the recognition and characterization of individual glycoconjugates.
