Excerpt:
"Methods: By taking advantage of a newly developed nanoplatform that allows the in vivo preferential transfection of tumor infiltrating myeloid cells (TIMC, aka Myeloid derived suppressor cells, MDSC, and tumor associated macrophages, TAM), we evaluated the effect of CCR-1, CCR-2, CCR-4, CCR-5 and/or CCR-7 silencing on TAMC trafficking, phenotype, and function.
Results: While CCR-4 and -7 targeted silencing did not affect tumor progression, simultaneous silencing of CCR-1 and CCR-5 significantly restrained tumor growth and greatly modifies tumor micro-environment. Mechanistic in vivo and in vitro analysis surprisingly indicate that myeloid cell trafficking was not altered whereas myeloid cell polarization was. In particular, CCR-1 and CCR-5 blockade restrained MDSC differentiation and promote the accumulation of retinoblastoma positive, neutrophil-like cells with a strong tumoricidal activity."
