Abstract/Artist Statement

We have used transmission electron microscopy to analyze the localization of proteases in trichomonad parasites. In particular, we are interested in the location of a number of different cysteine proteases predicted to be in lysosome- like vesicles. One such protease, CP1, is predicted to have a preprodomain and a predicted transmembrane domain based on genomic analysis. Also, immunofluorescence of trichomonads reveals vesicular localization. Further analysis at the electron microscopic level also reveals vesicular localization. The analysis of these enzymes at the subcellular level will aid in the design of additional experiments to test the role of these parasites in pathogenesis.
