#3974 Small extracellular vesicles miR-183-5p derived from highly invasive pancreatic neuroendocrine tumors reprogram macrophages towards SPP1+ macrophages

Introduction: Highly-metastatic (HM) pancreatic neuroendocrine tumors (pNETs) are characterized by an early occurrence of lymph node and liver metastases and a poor prognosis. Single-cell sequencing analysis showed that HM pNETs had remarkable infiltration of SPP1+ macrophages, which were involved in cell migration, angiogenesis and small extracellular vesicles (sEVs).
