Figure 2. Platforms for Redirecting T Cells to Cancer.
(A) T cell receptors (e.g., anti-NY-ESOI) or chimeric antigen receptors (e.g., anti-CD19 CAR).
(B) CAR structure includes an extracellular antigen recognition domain fused to intracellular TCR signaling domains (CD3z) and co-stimulatory domains (e.g., CD28 or 4-1BB).
(C) Current status of CD19 CAR therapies.
(D) Current status of engineered T cells directed toward solid tumors.
