TNFRSF13B Variant-Induced TACI Dysregulation Underlies CAEBV Pathogenesis.

ABSTRACT: The tumor necrosis factor (TNF) receptor superfamily member, transmembrane activator and CAML interactor (TACI) encoded by TNFRSF13B, are extensively involved in immune responses. In our previous work, TNFRSF13B exon 2 variants were recurrently identified in chronic active Epstein-Barr virus disease (CAEBV). 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
