CD47 Expression in Solid Tumors Correlates with Phagocytic Tumor-Associated Macrophage Gene Signature
Ontology highlight
ABSTRACT: CD47 is a “don’t eat me” signal that is frequently overexpressed in tumors to evade phagocytosis by tumor associated macrophages (TAM). Investigational agents targeting CD47, such as magrolimab, aim to induce phagocytosis of tumor cells by TAMs. Previously, two functionally defined key TAM subsets have been identified: complement C1q C chain positive (C1QC) TAMs, which display pro-phagocytic activity, and secreted phosphoprotein 1 positive (SPP1) TAMs that express pro-angiogenic markers. Here we characterize CD47 expression and its relationship with tumor macrophages in solid tumor samples.
