The National Institutes of Health (NIH), through the National Cancer Institute (NCI), is offering a funding opportunity titled "Microbial-based Cancer Imaging and Therapy - Bugs as Drugs" (PAR-25-107). This initiative invites grant applications that explore the use of bacteria, archaebacteria, bacteriophages, and non-oncolytic viruses to investigate their interactions with tumors and the immune system, aiming to develop innovative strategies for cancer imaging and therapy, particularly for oral cancers. The program encourages multidisciplinary collaboration among experts in microbiology, cancer biology, and immunology to address challenges associated with solid tumors and metastases. Applications will be accepted starting January 5, 2025, with no budget limit, and the project period can extend up to five years.
