Transcription factor Etv3 controls the tolerogenic function of dendritic cells Dendritic cells (DCs) facilitate the maintenance of immunological tolerance in the steady state. We report that transcription factor Etv3 is preferentially expressed in mature DCs, including tissue-de...

“DCs from patients with systemic #lupus erythematosus that have variants in the ETV3 gene previously linked to the disease had lower expression of ETV3 compared with DCs from individuals that did not carry the allele. “

Myelin antigen capture in the CNS by B cells expressing EBV latent membrane protein 1 leads to demyelinating lesion formation Myelin-reactive B cells entering the central nervous system capture cognate antigen from the parenchyma. Without T cell help, they rapidly die; however, Epstein-Barr virus LMP1 enables them to bypass ...

“•Naive myelin-reactive B cells enter the brain and capture antigen
•B cells capturing antigen in the brain die by activation-induced cell death
•EBV protein LMP1 can rescue B cells from activation-induced cell death
•B cells rescued after antigen capture induce MS-like lesions”

CD21 primes extrafollicular differentiation of autoreactive B cells in a TLR7-driven lupus model CD21 initiates extrafollicular differentiation of autoantibody-secreting cells in an SLE model driven by TLR7 signaling.

📖”This marks a critical point in B cell fate commitment, whereby CD21 down-regulation initiates EF B cell proliferation and differentiation, driving the rapid production of ASCs. “

Epstein-Barr virus reprograms autoreactive B cells as antigen-presenting cells in systemic lupus erythematosus Epstein-Barr virus reprograms autoreactive B cells as antigen-presenting cells to promote pathogenic antinuclear T and B cell responses in lupus.

“These EBV-infected B cells with antigen-presenting abilities had the capacity to activate autoreactive helper T cells, setting off a chain reaction where those T cells could activate other autoreactive B cells, including uninfected ones.”

“RA is characterized by pathological fibroblast-like synoviocytes (FLSs)... To address this, Huang et al. focused on the role of small nucleolar RNA, C/D box 3 (SNORD3), which is up-regulated by inflammatory modulators that are important in RA models.”
