Modulation of angiogenesis and wound healing
Methods of regulating angiogenesis, ischemic injury and/or wound healing by modulating the activity of leptin, particularly as mediated by the leptin receptor, and/or the interaction between leptin and the leptin receptor. Correspondingly, these methods can also be used to treat diseases mediated by angiogenesis, including wound healing, tumors and tumor metastasis, diabetic microangiopathy, retinal neovascularization, neovascularization of adipose tissue and fat metabolism, revascularization of necrotic tissue, enhancement or vascularization in microvascular transplants, and ovarian follicle maturation. Assays for identifying agents that modulate leptin and/or leptin receptor-mediated angiogenesis and/or wound healing and their use in treating angiogenesis-mediated diseases or conditions involving wound healing are also disclosed.
1. A method to promote wound healing in a subject in need thereof, comprising: providing an agent capable of inducing a leptin or leptin receptor-mediated angiogenic response; and administering to a subject in need of wound healing, an effective amount of the agent to promote wound healing, wherein the agent is leptin.
2. The method of claim 1 , wherein the angiogenic response affects vascular cells in the subject.
3. The method of claim 1 , wherein administering comprises administering the agent locally and the vascular cell response occurs locally.
