    • Mutated proteins coded by a mutated env gene of a lentivirus, particularly FIV, HIV or CAEV, peptide fragments contained in said mutated proteins and expression vectors expressing said mutated proteins as well as the applications thereof are described. The peptide fragments are contained in the principal immunodominant domain (PID) of the transmembrane protein (TM) of lentiviruses and particularly of feline immunodeficiency virus (FIV), human immunodeficiency virus (HIV-1 and HIV-2), arthritis virus and caprine encephalitis virus (CAEV), and are capable of modifying the immunogenic properties of the PID domain and of the Env protein of the lentiviruses containing them. Such fragments have one of the following sequences: SEQ ID N DEG 1: CNQNQWLCK, SEQ ID N DEG 2: CNQNQFLCK, SEQ ID N DEG 3: CNQNQLWCK, SEQ ID N DEG 4: CNQNQPFCK, SEQ ID N DEG 5: CEHQHFFCK, SEQ ID N DEG 6: CSMGTFFCK, SEQ ID N DEG 7: CLTDSFFCK, SEQ ID N DEG 8: CELKNFFCK, SEQ ID N DEG 9: CRPAAFFCK, SEQ ID N DEG 10: ELGCGSKLICKIP, SEQ ID N DEG 11: IWGCNQNQFFCTTAVPWN, SEQ ID N DEG 12: IWGVAFRQVCTTAVPW.
    • 描述了由慢病毒,特别是FIV,HIV或CAEV的突变env基因编码的突变蛋白,所述突变蛋白中包含的肽片段和表达所述突变蛋白的表达载体及其应用。 肽片段包含在慢病毒,特别是猫免疫缺陷病毒(FIV),人类免疫缺陷病毒(HIV-1和HIV-2),关节炎病毒和山羊脑炎的跨膜蛋白(TM)的主要免疫显性域(PID) 病毒(CAEV),并且能够修饰含有它们的慢病毒的PID结构域和Env蛋白的免疫原性。 这样的片段具有以下序列之一:SEQ ID NO:CNQNQWLCK,SEQ ID NO:CNQNQFLCK,SEQ ID NO:3:CNQNQLWCK,SEQ ID NO:4:CNQNQPFCK,SEQ ID NO:5:CEHQHFFCK,SEQ ID NO: ID N DEG 6:CSMGTFFCK,SEQ ID NO:7:CLTDSFFCK,SEQ ID NO:8:CELKNFFCK,SEQ ID NO:9:CRPAAFFCK,SEQ ID NO:10:ELGCGSKLICKIP,SEQ ID NO:11:IWGCNQNQFFCTTAVPWN,SEQ ID N DEG 12:IWGVAFRQVCTTAVPW。
