    • The present invention relates to recombinant human interleukin-3 (hIL-3) variant or mutant proteins (muteins) in which segments of the polypeptide sequence of the human IL-3 polypeptide have been replaced by segments of the murine (mouse) interleukin-3 (mIL-3) polypeptide to form human/murine chimeric hybrid polypeptides. The human/mouse IL-3 may have amino acid deletions at the N-terminus or the C-terminus or at both the N- and C- termini and in some cases may also contain additional amino acid substitutions or deletions. The human/murine IL-3 muteins retain at least one biological activity of native hIL-3 and may also exhibit an improved side effects profile such as a reduction in the stimulation of leukotriene release or histamine release. The invention also relates to pharmaceutical compositions containing the h/m IL-3 hybrids and methods for using them. Additionally, the present invention relates to recombinant expression vectors comprising nucleotide sequences encoding the IL-3 hybrid muteins, related microbial expression systems, and processes for making the IL-3 hybrids using the microbial expression systems.
    • 本发明涉及重组人白细胞介素-3(hIL-3)变体或突变蛋白(突变蛋白),其中人IL-3多肽的多肽序列的片段已被鼠(小鼠)白介素-3 (mIL-3)多肽以形成人/鼠嵌合杂合多肽。 人/小鼠IL-3可以在N末端或C末端或在N-和C-末端具有氨基酸缺失,并且在一些情况下也可能含有额外的氨基酸取代或缺失。 人/鼠IL-3突变蛋白保留天然hIL-3的至少一种生物活性,并且还可以表现出改善的副作用特征,例如减少刺激白三烯释放或组胺释放。 本发明还涉及含有h / m IL-3杂交体的药物组合物及其使用方法。 此外,本发明涉及包含编码IL-3杂交突变蛋白的核苷酸序列,相关的微生物表达系统和使用微生物表达系统制备IL-3杂交体的方法的重组表达载体。
