Abstract IA10: PMN-MDSC and neutrophils: Tale of two cells in cancer
Myeloid cells are a critical component of the tumor microenvironment. In cancer, the myeloid compartment is dramatically affected, which is now considered as one of the major immunological hallmarks of cancer. Accumulation of immunosuppressive macrophages (MΦ), defective dendritic cells (DC) function and expansion of pathologically activated immune suppressive immature myeloid cells – myeloid-derived suppressor cells (MDSC) are major changes in the myeloid compartment in cancer. The total population of MDSC consists of three groups of cells: the most abundant (>75%) immature, pathologically activated neutrophils (PMN-MDSC); the less abundant population of pathologically activated monocytes – (M-MDSC). Tumor associated macrophages (TAM) and DCs can persist in tissues for a long time, whereas PMN-MDSC have short lifespan ( Citation Format: Dmitry I. Gabrilovich.
