摘要
The Taenia crassiceps ORF strain is used to generate a murine model of cysticercosis, which is used for diagnosis, evaluation of drugs, and vaccination. This particular strain only exists as cysticerci, is easily maintained under in vivo and in vitro conditions, and offers an excellent model for studying the cytoskeletons of cestodes. In this study, several experimental approaches were used to determine the tissue expression of its cytoskeletal proteins. The techniques used were microscopy (video, confocal, and transmission electron), one-dimensional (1D) and two-dimensional (2D) electrophoresis, immunochemistry, and mass spectrometry. The tissue expression of actin, tubulin, and paramyosin was assessed using microscopy, and their protein isoforms were determined with 1D and 2D electrophoresis and immunochemistry. Nineteen spots were excised from a proteomic gel and identified by liquid chromatography-tandem mass spectrometry and immunochemistry. The proteins identified were classic cytoskeletal proteins, metabolic enzymes, and proteins with diverse biological functions, but mainly involved in detoxification activities. Research suggests that most noncytoskeletal proteins interact with actin or tubulin, and the results of the present study suggest that the proteins identified may be involved in supporting the dynamics and plasticity of the cytoskeleton of T. crassiceps cysticerci. These results contribute to our knowledge of the cellular biology and physiology of cestodes.
