Transcription profiling by microarray of High-density neutrophils in multiple myeloma and monoclonal gammopathy patients compared to healthy donors.

ABSTRACT: Multiple Myeloma (MM) is a plasma cell malignancy with a well- documented immune dysfunction. We previously showed that granulocyte-myeloid derived suppressor cells (G-MDSC) are increased in MM thus to contribute to refractoriness to lenalidomide. MM-, differently from MGUS, mesenchymal cells lead myeloid precursors to acquire G-MDSC phenotype, suggesting that MM-microenvironment can affect myeloid maturation. Because there is a phenotypic overlapping between G-MDSC and mature high-density neutrophils (HDN), we investigated functionally HDN to gauge their contribution in immune-suppression in patients affected by monoclonal gammopathy of uncertain significance (MGUS) and symptomatic MM.
