    • Disclosed are novel methods for increasing muscle mass by means of immunization against Growth Differentiation Factor 8 (GDF-8, myostatin). Immunization is preferably effected by administration of analogues of GDF-8 which are capable of inducing antibody production against homologous GDF-8. Especially preferred as an immunogen is homologous GDF-8 which has been modified by introduction of one single or a few foreign, immunodominant and promiscuous T-cell epitopes while substantially preserving the tertiary structure of the homologous GDF-8. Also disclosed are nucleic acid vaccination against GDF-8 and vaccination using live vaccines as well as methods and means useful for the vaccination. Such methods and means include methods for identification of useful immunogenic GDF-8 analogues, methods for the preparation of analogues and pharmaceutical formulations, as well as nucleic acid fragments, vectors, transformed cells, polypeptides and pharmaceutical formulations.
    • 公开了通过免疫接种生长分化因子8(GDF-8,肌生成抑制素)来增加肌肉质量的新方法。 免疫优选通过施用能够诱导针对同源GDF-8的抗体产生的GDF-8的类似物来实现。 特别优选的是作为免疫原的同源GDF-8,其通过引入一个或多个外来的免疫显性和混杂的T细胞表位而被修饰,同时基本上保留了同源的GDF-8的三级结构。 还公开了针对GDF-8的核酸疫苗接种和使用活疫苗的疫苗接种以及用于疫苗接种的方法和装置。 这些方法和手段包括鉴定有用的免疫原性GDF-8类似物的方法,制备类似物和药物制剂的方法,以及核酸片段,载体,转化细胞,多肽和药物制剂。
