Osteoprotegerin-Enabled Immune Evasion by Pathological Adipose Stromal Cells Drives Metabolic Dysfunction in Obesity

Hara Apostolopoulou, Yao Wang, William Reid Bolus…·Anil Bhushan

This study identifies senescent adipose progenitor cells (sAPCs) in obesity that produce osteoprotegerin (OPG), enabling immune evasion and metabolic dysfunction.

Blocking Osteoprotegerin Reprograms Cancer Associated Fibroblast to Promotes Immune Infiltration into the Tumor Microenvironment

Yao Wang, Hara Apostolopoulou, Im‐Hong Sun…·Anil Bhushan

This study identifies OPG-secreting CAFs as immunosuppressive stromal cells and shows that blocking OPG promotes immune infiltration and tumor regression in mouse models.
