Cytomegalovirus (CMV)-seropositivity has been shown to have a negative effect on influenza vaccine-specific antibody responses. In this paper, we confirm and extend these results showing for the first time, a negative association between CMV-seropositivity and B cell predictive biomarkers of optimal vaccine responses. These biomarkers are switched memory B cells and AID in CpG-stimulated B cell cultures measured before vaccination which positively correlate with the serum response to the influenza vaccine. We also found that CMV-seropositivity is associated with increased levels of B cell-intrinsic inflammation and these both correlate with lower B cell function. Finally, CMV-seropositivity is associated with decreased percentages of individuals responding to the vaccine in both young and elderly individuals.
巨细胞病毒(CMV)血清阳性已被证明对流感疫苗特异性抗体反应有负面影响。在本文中,我们首次证实并扩展了这些结果,表明CMV血清阳性与最佳疫苗反应的B细胞预测生物标志物之间存在负相关。这些生物标志物是在接种疫苗前测量的CpG刺激的B细胞培养物中的转换记忆B细胞和AID,它们与流感疫苗的血清反应呈正相关。我们还发现,CMV血清阳性与B细胞内在炎症水平升高有关,而这两者都与较低的B细胞功能相关。最后,CMV血清阳性与年轻人和老年人中对疫苗有反应的个体百分比降低有关。
