Figure 7. Proposed mechanism of action of CARG-2020.

Figure 7.

top panel, Control no treatment ovarian tumors are “cold” and express/secrete IL-17 and PD-L1 leading to differentiation of pro-tumor M2 macrophages, which inhibit the expansion of cytotoxic CD8 T cells; bottom panel, CARG-2020, by expressing shRNA for PD-L1 and dominant negative for IL-17, in addition to promoting the secretion of IL-12, shifts the environment to a “hot” tumor and promotes the differentiation of antigen presenting cells and consequently expansion of cytotoxic CD8 T cells.
