What the grant funds
Through this Notice of Funding Opportunity (NOFO), the National Cancer Institute (NCI) solicits grant applications proposing to utilize bacteria, archaebacteria, bacteriophages, or other non-oncolytic viruses and their natural products to study the underlying mechanisms of the complex interactions between microorganisms, tumors, and the immune system, and to explore their clinical potential for cancer imaging, therapeutics or diagnostics. Projects can focus on using microorganisms as anti-tumor agents, as activators of anti-tumor immunity, or as delivery vehicles for treatment, diagnosis, or imaging, complementing or synergizing with existing tools and approaches. This NOFO will support basic mechanistic and preclinical studies in cell culture and animal models. Applicants are encouraged to address both the microbial and tumor aspects of microbial tumor interactions relevant to microbial-based cancer therapy (including therapies for oral cancer), tumor imaging, tumor detection, or diagnosis. This funding opportunity is part of broader NCI-sponsored research on microbial-based cancer therapy. (link to OCCAM)
