Hydroxyapatite Binding Peptide Lipid Nanoparticles for Biomimetic mRNA Delivery to Bone
Advanced Therapeutics, EarlyView.Targeted delivery of therapeutic mRNA to peripheral tissues, including bone, is currently challenging. In the current work, a hydroxyapatite binding peptide (HABP) is conjugated to mRNA lipid nanoparticles (LNPs). HABP‐LNPs delivered systemically are demonstrated to reduce transfection in the liver and improve transfection in the femurs of mice ...

The role of immune cells in modulating chronic inflammation and osteonecrosis
Frontiers in Immunology, 2022 Osteonecrosis occurs when, under continuous stimulation by adverse factors such as glucocorticoids or alcohol, the death of local bone and marrow cells leads to abnormal osteoimmune function.

, 2018 Introduction: decreased blood flow to the head of femur is a degenerative process leading to cell death and eventually to osteonecrosis. It occurs mostly in people aged 20-40 and is a common presentation for orthopedic surgery consultation. The surgeons usually decide management plan on a case basis, and depending on the age of the patient, gender ...

Viridicatol from the Deep‐Sea‐Derived Fungus Alleviates Bone Loss by Targeting the Wnt/SHN3 Pathway
Advanced Science, EarlyView.Viridicatol (VDC), isolated from the deep‐sea‐derived fungus, enhances osteogenesis in vitro and in vivo by targeting Wnt/SHN3 signaling pathway. It can be delivered via engineered nanovesicles to mitigate bone loss of osteoporosis, fracture repair, and osteogenesis imperfecta.
