| Outline of Final Research Achievements |
Using parasitic helminths inhabiting various tissue environments, this research project was undertaken to elucidate underlying mechanisms for their infectious establishment and maintenance by analyzing expression and regulation of mitochondrial proteins, especially respiratory chains, responding to changing oxygen tension. Comparative mass spectrometric analyses, using 2D-PAGE followed by in-gel digestion and shotgun method, of mitochondrial proteins of Ascaris suum adult and Caenorhabditis elegans dwelling in anaerobic host intestine and free-living under aerobic conditions, respectively, revealed that the protein profiles were characteristic of the respective nematodes. The larva of Spirometra erinaceieuropaei living under dermal tissues, like Paragonimus westermani, was shown to possess both aerobic and anaerobic mitochondria.
