    摘要： The present invention is directed stromal cell derived factor-1 peptides that have been mutated to make them resistant to digestion by the proteases dipeptidyl peptidase IV (DPPIV) and matrix metalloproteinase-2 (MMP-2) but which maintain the ability of native SDF-1 to attract T cells. The mutants may be attached to membranes formed by self-assembling peptides and then implanted at sites of tissue damage to help promote repair.

    摘要翻译： 本发明涉及已被突变的基质细胞来源的因子-1肽，使得它们对蛋白酶二肽基肽酶IV（DPPIV）和基质金属蛋白酶-2（MMP-2）的消化具有抗性，但保持天然SDF- 1吸引T细胞。 突变体可以连接到通过自组装肽形成的膜，然后植入组织损伤部位以帮助促进修复。

    摘要： The present invention is directed to a therapeutic composition in which human PDGF is bound directly to peptides that self assemble into a biologically compatible gel. When implanted in a patient's body, the composition provides for the slow, sustained release of PDGF. The composition will be especially useful in treating patients who have undergone a myocardial infarction.

    摘要： The present invention is directed to methodology that allows a variety of compounds to be attached to self-assembling peptides using biotin/streptavidin linkages. The peptides can be used to form a biologically compatible membrane that promotes the growth and differentiation of cells. The attached therapeutic agents can be used to promote this process and the gel along with the growing cells can be implanted at a site in vivo where tissue repair is needed. Alternatively, membranes can be used for culturing cells in vitro or can be used for delivering drugs in vivo in the absence of seeded cells.

    摘要： Provided herein are ligand dimers, compositions thereof, as well as methods of their use. The ligand dimers provided can comprise at least one ligand to a Her receptor and can be used to force dimerization of specific receptor pairs. The forced dimerization of specific receptor pairs can be used to control (e.g., promote or inhibit) signaling, and, therefore, the ligand dimers provided can also be used in various forms of treatment in which such signaling control is beneficial to a subject. It follows that methods for controlling signaling are provided as are various methods of treatment.
