在此,我们研究了空LNP (eLNP), mrna疫苗的成分,对来自年轻人和老年人的细胞的抗病毒途径和免疫功能的影响。eLNP诱导单核细胞来源的树突状细胞(mddc)成熟。我们进一步表明,eLNP上调CD40并诱导多种DC亚群和单核细胞的细胞因子产生。这与TANK结合激酶1 (pTBK1)和干扰素反应因子7 (pIRF7)的磷酸化一致。在eLNP反应中,健康老年人(65岁以下)与年轻人(<65岁)相比,CD40表达和IFN-γ输出减少。此外,老年人的细胞对eLNP刺激有失调的抗病毒信号反应,通过I型IFN产生缺陷和吞噬来衡量。总体而言,我们的数据显示eLNP在引发DC成熟和先天免疫信号通路方面的功能,这些信号通路在老年人中受损,导致对基于SARS-CoV-2 mrna的疫苗的免疫应答降低。空脂质纳米颗粒在诱导树突状细胞成熟和先天免疫信号传导中的作用在老年人中被削弱,可能导致对基于SARS-CoV-2 mrna的疫苗的免疫反应降低。
Herein, we studied the impact of empty LNP (eLNP), component of mRNA-based vaccine, on anti-viral pathways and immune function of cells from young and aged individuals. eLNP induced maturation of monocyte derived dendritic cells (MDDCs). We further show that eLNP upregulated CD40 and induced cytokine production in multiple DC subsets and monocytes. This coincided with phosphorylation of TANK binding kinase 1 (pTBK1) and interferon response factor 7 (pIRF7). In response to eLNP, healthy older adults (>65 yrs) have decreased CD40 expression, and IFN-γ output compared to young adults (<65 yrs). Additionally, cells from older adults have a dysregulated anti-viral signaling response to eLNP stimulation, measured by the defect in type I IFN production, and phagocytosis. Overall, our data show function of eLNP in eliciting DC maturation and innate immune signaling pathways that is impaired in older adults resulting in lower immune responses to SARS-CoV-2 mRNA-based vaccines. The role of empty lipid nanoparticles in eliciting dendritic cell maturation and innate immune signaling is shown to be impaired in older adults, potentially contributing to lower immune responses to SARS-CoV-2 mRNA-based vaccines.
