Novel Listeria Vectors Secreting Gut Flora Altering Agents to Prevent Colon Cancer and Treat Colitis
Abstract
In the prior period we obtained needed IACUC and biosafety approvals, and developed the backbone Listeria vector needed to produce the B7-H1 scFv and B7-H1-expressing Listeria vectors for follow up work. We demonstrated the significance of host B7-H1 in preventing/mitigating colitis and also colon cancer, suggesting that a B7-H1-expressing vector could be useful for clinical uses in colitis and cancer prevention. We generating a full PD-L1 KO cell line using CRISPR to optimize library screening for anti-B7-H1 scFv. We collected useful data on immune and signaling events in colon during DSS-induced colitis to guide studies of colon tissue explants.
