Description of the Book:

In the funding period we have optimized phage-screens to select clones that differentially bind to either tumor infiltrating cytotoxic (CD8+) lymphocytes, activated CD8+ lymphocytes from the spleen, or un-activated naive CD8+ T cells. We have developed a high-throughput flow cytometric approach that allows us to screen the specificity of several phage clones for each of these CD8+ populations. Using this initial approach we have identified 17 phage that selectively bind TIL rather than effector cells. However, none of these phage influenced CD8+ TIL expansion or function in vitro. Using a novel NextGeneration sequencing approach, we have further defined another 1,000,000 phage that selectively bind TIL, of which 100,000 are unique reads. Highly represented phage have been subcloned and are being tested for in vitro function. We have identified one phage that augments T cell expansion in vitro. Phage have been tested for their ability to image tumors
