与单剂量相比,两剂辅助型流感疫苗在常见变性免疫缺陷 (CVID) 患者中显著增加了托尔样受体 (TLR) 表达. 这表明一种有希望的方法来增强CVID的先天免疫力.
科学领域:
- 免疫学 免疫学 免疫学
- 疫苗学 疫苗学 疫苗学
- 传染性疾病 传染性疾病
背景情况:
- 评估疫苗特异性T细胞反应和免疫性仍然具有挑战性,特别是在细胞免疫力方面.
- 对患有先天性免疫错误 (IEI),特别是抗体缺乏症的患者来说,评估细胞免疫力至关重要.
- 疫苗有效性和免疫性缺乏标准化的标准.
研究的目的:
- 为了研究一剂和两剂非活化辅助型亚单元流感疫苗的影响.
- 分析对免疫细胞和淋巴细胞子群体内体托尔类受体 (TLR) 表达的作用.
- 在常见可变免疫缺陷 (CVID) 患者中研究这些影响.
主要方法:
- 流细胞计用于分析淋巴细胞亚群和TLR表达.
- 六名CVID患者接受了一剂四价辅助型流感疫苗 (2018-2019).
- 9名CVID患者接受了两剂三价无活性流感疫苗 (2019-2020年).
主要成果:
- 在接种疫苗后,主要淋巴细胞亚群中没有观察到显著的变化.
- 在粒细胞,单细胞和淋巴细胞中检测到TLR3和TLR9表达的显著增加.
- 较高的TLR表达与两剂接种方案相比,与单剂接种有关.
结论:
- 这项研究是首次报告CVID患者同时进行两剂接种疫苗的策略.
- 两剂疫苗接种与免疫细胞TLR表达升高相关,表明增强的先天免疫力.
- 辅助疫苗对CVID患者来说是有前途的,因此需要进一步研究最佳的疫苗接种策略.

NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
