doi: 10.3892/mmr.2026.13878

Figure Lengend Snippet: Summary graphic illustration. This illustration summarizes the proposed model during pituitary adenoma invasion. The tumor invasive front abuts an intact sphenoid sinus mucosa, forming a distinct boundary. The mucosal compartment is enriched for ionised calcium binding adaptor molecule 1-positive macrophages with an M1-like predominance and IgG-high B cells. B cell-derived IgG promotes M2-to-M1 macrophage reprogramming, while coordinated IFN-γ and IL-6 production establishes a tumor-suppressive cytokine gradient that decreases from mucosa toward the tumor core, constraining proliferation and migration via JAK-STAT1 activation. Therapeutically, anti-CD47 monoclonal antibody blocks the CD47-SIRPα ‘don't-eat-me’ axis and augments antibody-dependent cellular phagocytosis, highlighting a strategy for immune checkpoint-targeted therapy that may complement surgical management.
