CSF1R‐ and SHP2‐Inhibitor‐Loaded Nanoparticles Enhance Cytotoxic Activity and Phagocytosis in Tumor‐Associated Macrophages
Abstract
Immune modulation of macrophages has emerged as an attractive approach for anti‐cancer therapy. However, there are two main challenges in successfully utilizing macrophages for immunotherapy. First, macrophage colony stimulating factor (MCSF) secreted by cancer cells binds to colony stimulating factor 1 receptor (CSF1‐R) on macrophages and in turn activates the downstream signaling pathway responsible for polarization of tumor‐associated macrophages (TAMs) to immunosuppressive M2 phenotype. Second, ligation of signal regulatory protein α (SIRPα) expressed on myeloid cells to CD47, a transmembrane protein overexpressed on cancer cells, activates the Src homology region 2 (SH2) domain ‐phosphatases SHP‐1 and SHP‐2 in macrophages. This results in activation of “eat‐me‐not” signaling pathway and inhibition of phagocytosis. Here, it is reported that self‐assembled dual‐inhibitor‐loaded nanoparticles (DNTs) target M2 macrophages and simultaneously inhibit CSF1R and SHP2 pathways. This results in efficient repolarization of M2 macrophages to an active M1 phenotype, and superior phagocytic capabilities as compared to individual drug treatments. Furthermore, suboptimal dose administration of DNTs in highly aggressive breast cancer and melanoma mouse models show enhanced anti‐tumor efficacy without any toxicity. These studies demonstrate that the concurrent inhibition of CSF1‐R and SHP2 signaling pathways for macrophage activation and phagocytosis enhancement could be an effective strategy for macrophage‐based immunotherapy.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
