title: The potential of clostridial spores as therapeutic delivery vehicles in tumour therapy.
abstract: Despite substantial investment in prevention, treatment and aftercare, cancer remains a leading cause of death worldwide. More effective and accessible therapies are required. A potential solution is the use of endospore forming Clostridium species, either on their own, or as a tumour delivery vehicle for anti-cancer drugs. This is because intravenously injected spores of these obligate anaerobes can exclusively germinate in the hypoxic/necrotic regions present in solid tumours and nowhere else in the body. Research aimed at exploiting this unique phenomenon in anti-tumour strategies has been ongoing since the early part of the 20th century. Only in the last decade, however, has there been significant progress in the development and refinement of strategies based on spore-mediated tumour colonisation using a range of clostridial species. Much of this progress has been due to advances in genomics and our ability to modify strains using more sophisticated gene tools.
