Fig. 2. Schematic illustration of DCL structure and biomechanisms of complementary targeting strategy.
(A) The design of the proof-of-principle binary DCL for TNBC. (B) DCL increases cellular binding using precisely matched, multivalent ligand-receptor interactions. (C) DCL enhances internalization using cooperative ICAM1 and EGFR endocytosis pathways. (D) DCL improves therapeutic efficacy using synergistic blockade of ICAM1 and EGFR signaling cascades.
