Introduction: Bisphosphonate treatment in children with osteogenesis imperfecta reduces bone catabolism and relies on modelling to form new bone. An anabolic treatment, anti-sclerostin antibody (Anti-SOST Ab), is being investigated in clinical trials. We hypothesized that combined treatment may produce superior outcomes in OI.Methods: Female Col1a2 G610C mice and their wild type littermates (WT) were treated from week 5 to week 9 of life with either sali...

Objectives: While local gene therapy for bone applications has shown some success in preclinical models, systemic delivery of transgenes to the skeleton remains a considerable challenge. Viral vectors such as adeno-associated viruses (AAVs) have great potential as vectors for systemic transgene delivery and may be adapted for emerging gene editing technologies. Furthermore, AAV vectors can have high efficiency, low immunogenicity, and selective tropism towards different tissue...

Recent studies have demonstrated that the global or osteoblast-specific deletion of neuropeptide Y Y1 receptor (Y1R), as well as the pharmacological blockade of Y1R, leads to pronounced anabolic effects in bone metabolism. This suggests that anti-Y1R drug therapy might have clinical applications for the prevention/recovery of bone loss occurring in osteoporosis. Given the high fracture incidence in this target population, it remained...
