Macrophage infiltration has been identified as an independent, poor prognostic factor for patients afflicted with various cancer entities. However, the characterization of tumor-associated macrophages (TAMs) prior to and following cancer patient treatment has been limited. Our study analyzed tumor biopsies before and after anti-CSF-1R antibody treatment unraveling the nature of TAMs and providing novel insights into their phenotypic and functional characteristics in cancer.
Keywords: CSF-1R; RG7155; TAM depletion; myeloid cells; tumor-associated macrophages.
