The aim is to explore the role of immune aging and macrophage signaling in the progression of smoldering multiple myeloma.
Employed single-cell RNA sequencing to analyze 125 samples from SMM patients and healthy donors.
Profiled immune and stromal compartments in BM and peripheral blood to assess alterations.
Focused on immune aging signatures and macrophage signaling pathways.
Increased immune aging with elevated exhaustion and senescence markers in SMM T cells and B cells.
Enhanced macrophage inhibitory factor signaling correlated with IL-6 production and tumor-supportive macrophage polarization.
Identified the tumor microenvironment as a key player in disease progression, particularly through MIF-mediated interactions.
