Title (EN) CD4 HELPER T-CELL EPITOPE FUSION PEPTIDE AND VACCINE THEREOF
(FR) PEPTIDE DE FUSION D'ÉPITOPE DE LYMPHOCYTE T AUXILIAIRE CD4 ET VACCIN ASSOCIÉ
(ZH) 一种CD4辅助性T细胞表位融合肽及其疫苗
Abstract:
(EN) Disclosed are a CD4 helper T-cell epitope fusion peptide, a nucleic acid encoding same, and an immune composition comprising same. The epitope fusion peptide comprises a cytomegalovirus epitope and an influenza virus epitope. The epitope fusion peptide can substantially improve the level of the cellular immune response to an immunogen of interest, particularly a weak immunogen, and is an effective means for overcoming the immune system's immune tolerance to an antigen, particularly a tumour antigen or an infection-related antigen, and is suitable for efficiently enhancing the potency of vaccines.
(FR) L'invention concerne un peptide de fusion d'épitope de lymphocyte T auxiliaire CD4, un acide nucléique codant pour celui-ci, et une composition immunitaire le comprenant. Le peptide de fusion d'épitope comprend un épitope de cytomégalovirus et un épitope du virus de la grippe. Le peptide de fusion d'épitope peut sensiblement améliorer le niveau de la réponse immunitaire cellulaire à un immunogène d'intérêt, en particulier un immunogène faible, et est un moyen efficace pour surmonter la tolérance immunitaire du système immunitaire à un antigène, en particulier un antigène tumoral ou un antigène associé à une infection, et est approprié pour améliorer de manière efficace la puissance de vaccins.
(ZH) 一种CD4辅助性T细胞的表位融合肽、其编码核酸以及包含其的免疫组合物。所述表位融合肽包含巨细胞病毒表位和流感病毒表位。所述表位融合肽能大幅度提高目的免疫原,尤其是弱免疫原的细胞免疫应答水平,是克服免疫系统对抗原免疫耐受性,尤其是肿瘤抗原或感染相关抗原的有效手段,适用于高效增强疫苗的效力。
