Strategies for promoting NRT cell tumor infiltration and modifying suppressive TME. A Improve tumor reactive T cell infiltration through inhibiting immunosuppressive signals, and promoting the expression of chemokines and the release of tumor specific antigens. B Eliminate the physical barrier effect of extracellular matrix(ECM) using drugs such as nab-paclitaxel. C Normalize abnormal vasculature by using VEGFR inhibitor. D Deplete immunosuppressive cells(Treg and MDSCs) and inhibit their activation signals. E Repolarize tumor-associated macrophages(TAM) from M2 towards M1. F Induce the formation of tertiary lymphoid structures(TLSs)(chemotherapy, ICIs, vaccine and stromal cell)
