Developing an effective vaccine against Staphylococcus aureus (S. aureus) is a key global health concern, especially with the increased reports of multidrug-resistant (MDR) S. aureus strains. Previous attempts for S. aureus vaccine development were unsuccessful. In this study, Manganese transport protein C (MABC) B cell epitopes, Nickel ABC transporter (NABC) B cell & T cell epitopes, and Phosphatidylinositol phosphodiesterase (PIc) B cell & T cell epitopes were used as a vaccine in mice skin infection model. Mice immunized with peptide mixture and MABC peptide group showed the best skin lesion healing results. The protection level was correlated with the highest IgG level, highest levels of interferon-gamma (INF γ), and lowest levels of interleukin-2 (IL-2). The peptide mixture group also showed the highest count of CD4/ CD8 cells. Results demonstrated that the inclusion of B cell and T cell epitopes of multiple genes improved both the humoral and cellular immunity and resulted in the best outcome in the skin infection mice model. A more expanded in-vivo study in different mice models is recommended for testing MABC, NABC, and PIc B cells and T cells peptides cocktail as promising S. aureus vaccine.
研发一种有效的抗金黄色葡萄球菌疫苗是全球主要的健康关注点,尤其是在耐多药金黄色葡萄球菌菌株报告增多的情况下。先前研发金黄色葡萄球菌疫苗的尝试均未成功。在本研究中,锰转运蛋白C(MABC)B细胞表位、镍ABC转运蛋白(NABC)B细胞和T细胞表位以及磷脂酰肌醇磷酸二酯酶(PIc)B细胞和T细胞表位被用作小鼠皮肤感染模型中的疫苗。用肽混合物和MABC肽组免疫的小鼠显示出最佳的皮肤损伤愈合效果。保护水平与最高的IgG水平、最高水平的干扰素-γ(INFγ)以及最低水平的白细胞介素-2(IL-2)相关。肽混合物组还显示出最高数量的CD4/CD8细胞。结果表明,包含多个基因的B细胞和T细胞表位可改善体液免疫和细胞免疫,并在皮肤感染小鼠模型中产生最佳结果。建议在不同小鼠模型中进行更广泛的体内研究,以测试MABC、NABC和PIc B细胞和T细胞肽鸡尾酒作为有前景的金黄色葡萄球菌疫苗。
