Here we aim to reveal the roles of TNFRSF13B variants in CAEBV, and investigate the feasibility of targeting TNFRSF13B/TACI as a new approach to control EBV infection. The lymphoblastoid cell lines (LCL) models carrying homozygous TNFRSF13B exon 2 frameshift mutations were constructed using CRISPR/Cas9. Immunological assays, transcriptomic analysis, and gene silencing experiments were performed on LCL models to measure the effect of TNFRSF13B exon 2 variants and explore the underlying mechanisms. TACI ligands and a TLR9 agonist were applied to modulate TACI signaling and EBV activities. Frameshift mutations in exon 2 of TNFRSF13B significantly up-regulated the short isoforms of TACI (TACI-S) at the expense of its long isoforms (TACI-L) in LCLs. The up-regulated TACI-S induced more intense activation of NF-κB, MAPK, and Rho signaling pathways, leading to the switch of EBV activities to lytic reactivation. The subsequent increased viral load and viral IL-10 provide a rational for the susceptibility of variant carriers to CAEBV. The BAFF trimer, an indirect TACI-signaling inhibitor, also significantly suppressed the EBV lytic program. Gene silencing experiments indicated that XBP-1 might be involved in the TACI-mediated regulation of EBV lytic activities in EBV-immortalized B cells.

Our primary objective was to determine whether these vaccines elicit lasting changes in innate immune responses, particularly in monocyte populations and cytokine production following stimulation with a panel of agonists. The study was conducted at four time points: Day-0 (pre-vaccination), Day-28, Day-90, and Day-180 post-vaccination. We observed no significant differences in monocyte subpopulations between vaccine groups; however, cytokine and chemokine analysis revealed distinct immune signatures. While IL-6 and TNFα production remained unchanged after ex-vivo restimulation in the BNT162b2 group, individuals vaccinated with mRNA-1273 exhibited a sustained increase in the production of these cytokines, persisting for up to 180 days post-vaccination. Additionally, CCL2, a key chemokine involved in monocyte recruitment, was upregulated following mRNA-1273 vaccination but decreased in the BNT162b2 group, further supporting the finding of differential innate immune responses between the two vaccines. In conclusion, our study provides evidence that mRNA-1273, but not BNT162b2, induces immune responses consistent with the concept of trained immunity.
