    • Fusion proteins containing a first domain and a second domain, where the first domain contains a crosslinkable substrate domain and the second domain contains a fibrinolysis inhibitor, are provided. In a preferred embodiment, the fibrinolysis inhibitor is a protease inhibitor, preferably, aprotinin. The fusion protein optionally contains a degradable site between the fist domain and the second domain. In a preferred embodiment, the crosslinkable substrate domain is a transglutaminase substrate domain, more preferably a Factor XIIIa substrate domain. Also provided is a method for decreasing the degradation of a fibrin matrix, and supplemented fibrin matrices with reduced degradation rates. The method includes covalently crossHnking a fusion protein containing a fibrinolysis inhibitor to the matrix. The supplemented fibrin matrices contain lower concentrations of a fibrinolysis inhibitor covalently bound to the matrix, compared to the concentration of unbound fibrinolysis inhibitor required to achieve the same reduction in degradation of the fibrin matrix.
    • 提供了含有第一结构域和第二结构域的融合蛋白,其中第一结构域含有可交联底物结构域并且第二结构域含有纤维蛋白溶解抑制剂。 在一个优选的实施方案中,纤维蛋白溶解抑制剂是蛋白酶抑制剂,优选抑肽酶。 融合蛋白任选地在第一结构域和第二结构域之间含有可降解位点。 在优选的实施方案中,可交联底物结构域是转谷氨酰胺酶底物结构域,更优选是因子XIIIa底物结构域。 还提供了一种降低纤维蛋白基质降解的方法,以及降低降解速率的补充纤维蛋白基质。 该方法包括将含有纤维蛋白溶解抑制剂的融合蛋白共价交联到基质上。 与实现纤维蛋白基质降解相同降低所需的未结合的纤维蛋白溶解抑制剂的浓度相比,补充的纤维蛋白基质含有较低浓度的与基质共价结合的纤维蛋白溶解抑制剂。

    • Proteins are incorporated into protein or polysaccharide matrices for use in tissue repair, regeneration and/or remodeling and/or drug delivery. The proteins can be incorporated so that they are released by degradation of the matrix, by enzymatic action and/or diffusion. As demonstrated by the examples, one method is to bind heparin to the matrix by either covalent or non-covalent methods, to form a heparin-matrix. The heparin then non-covalently binds heparin-binding growth factors to the protein matrix. Alternatively, a fusion protein can be constructed which contains a crosslinking region such as a factor XIIIa substrate and the native protein sequence. Incorporation of degradable linkages between the matrix and the bioactive factors can be particularly useful when long-term drug delivery is desired, for example in the case of nerve regeneration, where it is desirable to vary the rate of drug release spatially as a function of regeneration, e.g. rapidly near the living tissue interface and more slowly farther into the injury zone. Additional benefits include the lower total drug dose within the delivery system, and spatial regulation of release which permits a greater percentage of the drug to be released at the time of greatest cellular activity.
    • 将蛋白质掺入用于组织修复,再生和/或重塑和/或药物递送的蛋白质或多糖基质中。 可以掺入蛋白质,使其通过降解基质,通过酶作用和/或扩散来释放。 如实施例所示,一种方法是通过共价或非共价方法将肝素与基质结合,形成肝素基质。 然后肝素将肝素结合生长因子非共价结合到蛋白质基质上。 或者,可以构建融合蛋白,其包含交联区域,例如因子XIIIa底物和天然蛋白质序列。 当需要长期药物递送时,例如在神经再生的情况下,在基质和生物活性因子之间引入可降解的键可能是特别有用的,其中期望在空间上改变作为再生的功能的药物释放速率 ,例如 快速靠近生物组织界面,并进一步向进入损伤区更慢。 额外的益处包括递送系统内的总药物剂量越少,释放的空间调节,允许在最大的细胞活动时释放更多百分比的药物。
