    • The major subunit of the Duffy blood group antigenic system, gp-Fy protein, has been isolated, as have two variants, gp-Fy alpha and/or gp-Fy beta , which are produced from the Duffy FY gene by a differential splicing mechanism. gp-Fy protein contains the receptor by which P. vivax enters red cells and causes malaria. gp-Fy protein has therapeutic value in the prevention of malaria and in the regulation of erythrocyte, neural and renal functions and can be combined with physiologically acceptable diluents to yield a therapeutic agent suitable for these purposes. Peptides corresponding to a portion of gp-Fy protein that contains the receptor also have been synthesized. gp-Fy protein and derived peptides have utility in the production of therapeutics, e.g., antibodies, complementary peptides, etc., which are also useful to treat malaria and regulate essential erythrocyte, neural and renal functions. Also provided are nucleic acid primers and probes which specifically bind to or hybridize with portions of the FY gene or DNA or RNA derived therefrom for detecting the presence of gp-Fy alpha and/or gp-Fy beta nucleic acids in tissues samples. Methods for detecting Duffy protein expression, i.e., differential expression of gp-Fy alpha and/or gp-Fy beta proteins are provided.
    • 已经分离了Duffy血型抗原系统gp-Fy蛋白的主要亚单位,其具有通过差异剪接机制从Duffy FY基因产生的两种变体gp-Fyα和/或gp-Fyβ 。 gp-Fy蛋白含有间日疟原虫进入红细胞并引起疟疾的受体。 gp-Fy蛋白在预防疟疾和调节红细胞,神经和肾功能方面具有治疗价值,并且可以与生理上可接受的稀释剂组合以产生适合于这些目的的治疗剂。 对应于含有受体的gp-Fy蛋白的一部分的肽也已经合成。 gp-Fy蛋白质和衍生肽可用于生产治疗剂,例如抗体,互补肽等,其也可用于治疗疟疾和调节重要的红细胞,神经和肾功能。 还提供了与FY基因的部分或其衍生的DNA或RNA特异性结合或杂交的核酸引物和探针,用于检测组织样品中gp-Fyα和/或gp-Fyβ核酸的存在。 提供了检测Duffy蛋白表达的方法,即gp-Fyα和/或gp-Fyβ蛋白的差异表达。

    • The invention provides a method of causing the degradation of fibrin(ogen) (i.e., fibrin, fibrinogen, and related substances) by means of a fibrinolytic metalloproteinase, preferably an endogenous metalloproteinase such as MMP-3. The method of the invention can be performed in vitro to provide diagnostic information characterizing fibrin(ogen) and fibrinolytic physiology. The method can also be performed in vivo as a method of thrombolytic therapy in which a fibrinolytic metalloproteinase is administered to a subject to degrade thrombus in situ. The endogenous fibrinolytic metalloproteinase can be administered in conjunction with other active agents, preferably with agents having thrombolytic activity to improve thrombolytic and fibrinolytic therapy. The invention further provides compositions containing a fibrinolytic metalloproteinase for the performance of fibrinolytic or thrombolytic procedures. Also provided are kits which include a fibrinolytic metalloproteinase for performing fibrinolytic or thrombolytic procedures.
    • 本发明提供了通过纤维蛋白溶解性金属蛋白酶(优选内源性金属蛋白酶如MMP-3)引起纤维蛋白(原子)(即纤维蛋白,纤维蛋白原和相关物质)降解的方法。 本发明的方法可以在体外进行以提供表征纤维蛋白(ogen)和纤维蛋白溶解生理学的诊断信息。 该方法也可以作为血栓溶解治疗方法在体内进行,其中向受试者施用纤维蛋白溶解性金属蛋白酶以原位降解血栓。 内源性纤维蛋白溶解性金属蛋白酶可以与其他活性剂联合施用,优选与具有溶栓活性的试剂一起施用以改善溶栓和纤维蛋白溶解治疗。 本发明还提供含有纤维蛋白溶解性金属蛋白酶用于纤维蛋白溶解或血栓溶解过程的组合物。 还提供了包括用于进行纤维蛋白溶解或血栓溶解过程的纤维蛋白溶解性金属蛋白酶的试剂盒。
