There is a need for new adjuvants that will induce immune responses to subunit vaccines. We show that a short peptide, named Hp91, whose sequence corresponds to an area within the endogenous molecule high mobility group box (HMGB1) protein 1 potentiates cellular immune responses to peptide antigen and cellular and humoral immune responses to protein antigen in vivo. Hp91 promoted the in vivo production of the immunomodulatory cytokines, IFN-γ, TNF-α, IL-6, and IL-12 (p70), as well as antigen-specific activation of CD8+ T cells. These results demonstrate the ability of a short immunostimulatory peptide to serve as an adjuvant for subunit vaccines.
需要新的佐剂来诱导亚单位疫苗的免疫反应。我们发现,一种名为 Hp91 的短肽,其序列对应于内源性分子高迁移率族蛋白 1(HMGB1)蛋白 1 内的一个区域,可增强体内对肽抗原的细胞免疫反应以及对蛋白抗原的细胞和体液免疫反应。Hp91 促进了免疫调节细胞因子 IFN-γ、TNF-α、IL-6 和 IL-12(p70)的体内产生,以及抗原特异性 CD8+T 细胞的激活。这些结果表明,一种短的免疫刺激性肽能够作为亚单位疫苗的佐剂。
