[Antibodies to basal cells of the parotid duct]

The use of indirect immunofluorescence technique confirmed the existence of spontaneous human auto-antibodies attaching to the basal cells in the excretory parotid duct. Analogically with literary data, based on the study of monoclonal antibodies, the author's opinion is that this is an auto-antibody with an unexpectedly narrow spectrum of specifically confined to antigen of cytokeratin polypeptides 13 and 16.
