  • A link between mitochondrial damage and osteoporosis

    New research from the School of Veterinary Medicine lays out a possible mechanism by which alcohol, cigarette smoke, and exposure to certain medications and toxins can weaken bone.
    Yellow pointers indicate large cells against a background of other microscopic material. Left panel has two smaller cells indicated while the right panel has three larger cells indicated.
    Mitochondrial damage is linked to the bone degradation seen in osteoporosis, according to Penn Vet researchers. Macrophages, a type of immune cell, that had dysfunctional mitochondria (right) were more likely to become osteoclasts—cells that break down bone—than control macrophages (left).
