Conceptual model of the in vivo experiment. On top vaccine cells (VC) are administered through intravenous injections, and then recognized by Cytotoxic T cells (TC) and Antibodies (AB) that kill them. Killed VC release both Interleukin-12 (IL12) and Tumor associated antigens (TAA). TAA are captured by antigen presenting cells (APC) and then presented to T helper cells (TH). IL12 stimulates both TH and TC actions. TH release interleukin-2 (IL2) which boosts TH, TC, and B actions and stimulates B cells to differentiate into plasma B cells (B). B release AB, and both AB and stimulated TC kill cancer cells (CC), which further release TAA.
