SPP1+ macrophages, characterized by elevated expression of the osteopontin gene (secreted phosphoprotein 1, SPP1), have emerged as key players in various pathological contexts, including aging, chronic inflammatory diseases, and cancer. While frequently classified a subclass tumor-associated macrophages oncological settings, their presence noncancer conditions, such aging-related disorders muscular suggests broader role beyond tumors. These share conserved traits, fibrosis promotion, extracellular matrix remodeling, immune modulation, often linked to poor clinical outcomes. This perspective explores multifaceted roles across diseases advocates for reclassification distinct macrophage subtype associated with or prolonged inflammation. Recognizing cross-disease relevance could reshape biology inform targeted therapeutic strategies.
