    Abstract: The present invention deals with a modified polypeptide comprising three contiguous segments N, L and C represented by the formula N-L-C and comprising: a N-helix region of gp41 (N), a C-helix region of gp41 (C), and a connecting loop comprising a synthetic linker (L) between the N and C-helices, the linker replacing amino acids 593-617 of gp41, the numbering scheme being based upon the prototypic isolate HIV-1 HxB2 Clade B strain, said polypeptide comprising the calveolin-1 neutralizing and 98.6 D epitopes, but not 2F5 and 4E10 epitopes, not the fusion peptide, the polypeptide having a minimal immunogenic cross-reactivity with human interleukin 2 (IL2).

    Abstract translation: 本发明涉及包含由NLC表示的三个连续片段N,L和C的修饰多肽,其包含:gp41(N)的N-螺旋区,gp41(C)的C-螺旋区,以及连接 所述多肽包含N和C-螺旋之间的合成接头(L),所述接头代替gp41的氨基酸593-617,编号方案基于原型分离物HIV-1 HxB2进化枝B菌株,所述多肽包含小牛血清素 - 1中和和98.6 D表位,而不是2F5和4E10表位,而不是融合肽,该多肽与人白介素2(IL2)具有最小的免疫原性交叉反应性。
