Strategies to therapeutically target TAMs in PDAC. Major TAM-targeting strategies in PDAC include (1) TAM depletion by blocking CSF1R signaling; (2) inhibition of TAM recruitment by blocking CCL2/CCR2 signaling; (3) suppressing the pro-tumorigenic activity of AAMs by inhibiting PI3Kγ, CD11b, IRF4 or TIE2; and (4) reprogramming TAMs towards a tumoricidal classically-activated endotype via CD40 agonists or inhibition of the ‘do not eat me’ CD47/SIRPα signaling axis to promote tumor cell phagocytosis.
