    • A sequence in the coat glycoprotein of rabies virus is identified as the molecular basis for an essential step in the pathogenesis of the virus, the binding of virus to acetylcholine receptor at neuromuscular junctions prior to virus uptake into peripheral nerves. Based on this discovery, synthetic peptide-based, anti-rabies vaccines are prepared. The active ingredient of such vaccines is a synthetic protein, which is a conjugate with an immunogenic carrier protein of a synthetic peptide with a sequence which includes a sequence which is substantially the same as a substantial portion of the sequence of the acetylcholine receptor-binding segment of the rabies virus coat protein. Anti-rabies antisera, and anti-rabies antibodies, are prepared by injecting a mammal with a synthetic protein of the invention in a manner that induces an immune response in the mammal against the synthetic protein. Hybridomas which secrete anti-rabies antibodies, which bind to specific epitopes on or near the acetylcholine receptor binding segment on the rabies virus coat glycoprotein, are prepared with B cells immunized in vitro with a synthetic peptide or synthetic protein of the invention or taken from a mammal inoculated with such a peptide or protein. The anti-rabies vaccines of the invention avoid risks associated with currently available anti-rabies vaccines. The antisera and antibodies of the invention are useful therapeutically to induce passive anti-rabies immunity in a mammal that has been exposed to rabies virus. The antisera and antibodies are also useful for diagnosing whether a mammal is rabid and whether a mammal has been exposed to live rabies virus.
    • 鉴定狂犬病病毒外壳糖蛋白中的序列是病毒发病机理中必不可少的步骤的分子基础,在病毒摄入到外周神经之前,病毒与神经肌肉接头处的乙酰胆碱受体结合。 基于这一发现,制备合成的基于肽的抗狂犬病疫苗。 这种疫苗的活性成分是合成蛋白质,其是具有合成肽的免疫原性载体蛋白的缀合物,其具有序列,其包含与乙酰胆碱受体结合区段的大部分基本相同的序列 的狂犬病病毒外壳蛋白。 抗狂犬病抗血清和抗狂犬病抗体通过以对哺乳动物诱导针对合成蛋白质的免疫应答的方式向哺乳动物注射本发明的合成蛋白质来制备。 使用与本发明的合成肽或合成蛋白质体外免疫的B细胞一起制备分泌抗狂犬病抗体的杂交瘤,其与狂犬病病毒外壳糖蛋白上的乙酰胆碱受体结合片段上或附近的特异性表位结合, 用这种肽或蛋白质接种的哺乳动物。 本发明的抗狂犬病疫苗避免了与目前可用的抗狂犬病疫苗相关的风险。 本发明的抗血清和抗体可用于在暴露于狂犬病病毒的哺乳动物中诱导被动抗狂犬病免疫。 抗血清和抗体也可用于诊断哺乳动物是否狂犬病以及哺乳动物是否已经暴露于活狂犬病毒。

    • The invention provides compositions of matter having pharmacological activity and which are useful in the treatment of the symptoms of neurological and other disorders, particularly those disorders which are caused by malfunction of the immune mechanism. The present compositions include venoms and/or venom fractions extracted from various elapid and viperid snakes and generally include a postsynaptic component capable of binding to nicotinic acetylcholine receptors of cells, a presynaptic component capable of inhibition of acetylcholine release, and a viperid component stimulative of the immune system. According to the present invention, the viperid component of the present compositions of matter preferably constitutes a venom fraction which is absent certain enzymes such as L-amino acid oxidase and phosphodiesterase, these compositions being of particular utility due to the absence of a hemorrhagic effect when used in the treatment of mammals. Methods of preparation and use of the present compositions of matter are also disclosed.
