摘要:
The invention relates to compositions and methods as part of a pharmacotherapeutic strategy that targets the endochondral ossification process in a pharmacologically selective and site-specific manner. A variety of orthopedic pathologies are caused by or associated with generalized or local dysregulation of endochondral ossification, for example trauma to the bone growth plate or diaphysis can cause a serious imbalance in bone growth, leading to progressive deformity that today can only be treated surgically. Dysregulated endochondral ossification is also behind heterotopic ossification, which arises in soft tissues and causes pain, decrease in mobility and other clinical problems. The invention therefore provides RARy agonist and antagonist nanoparticle compositions for treating abnormal endochondral ossification and bone growth that can deliver robust local therapeutic control over a particular long bone's growth with a long-lasting effect.
