Secretory granules in rat submandibular acinar cells during experimental Chagas disease.

ABSTRACT

The fine structure of rat submandibular glands has been compared in control and infected-rats with Y strain of Trypanosoma cruzi at day 18 of infection. In the acinar cells of the infected rats the secretory granules exhibit a variety of morphological types suggesting and early form of secretion product or a new secretory protein.
