LAMP3 and neoplasm: One subset of dendritic cells (plasmacytoid dendritic cells [DCs]) was rarely found in normal lung sites compared to tumor sites and metastatic lymph nodes and exhibited an immunosuppressive phenotype with the upregulation of LILR and GZMB but loss of CD86, CD83, CD80, and LAMP3.140 A rare cell type, defined as follicular DCs, was identified by Wu et al.141 Furthermore, Lambrechts et al. detected a fibroblast cluster highly expressing COL10A1 that was strongly enriched at the tumor site and exhibited a strong EMT signal.137
