| 摘要 |
The invention provides a method of stimulating TGF-beta activity, comprising contacting latent TGF-beta with an amount of an activating peptide from TSP effective to convert latent TGF-beta to active TGF-beta. Also provided is a method of inhibiting the stimulation of TGF-beta activity, comprising contacting latent TGF-beta with an amount of an inhibiting peptide from TSP effective to inhibit conversion of latent of TGF-beta to active TGF-beta. The invention also provides a method of enhancing wound healing, comprising the step of administering to the wound site an amount of an activating peptide from TSP effective to convert latent TGF-beta to active TGF-beta, the activation of TGF-beta resulting in enhanced wound healing. A method of preventing excessive fibrosis stimulated by TGF-beta in pathology is also provided, comprising administering to a site of potential fibrosis an amount of inhibiting peptide from TSP effective to inhibit conversion of latent TGF-beta to active TGF-beta, resulting in reduced fibrosis. The invention also provides a method of blocking TGF-beta-mediated inhibition of endothelial cell proliferation comprising contacting the endothelial cells with an inhibiting peptide effective to inhibit conversion of latent TGF-beta to active TGF-beta, resulting in proliferation of endothelial cells.
