Project description
Regulation of immune system hyperactivation in lupus
In autoimmune diseases the immune system mistakenly attacks its own healthy tissues and organs. Systemic lupus erythematosus (SLE) is associated with B cell dysfunction and production of autoantibodies, leading to heterogeneous clinical phenotypes. However, little is known about the regulatory mechanisms in place driving aberrant B cell function in SLE. To answer this question, researchers of the EU-funded RoBE project will focus on the B cell protein BANK1, which has a putative role in B cell hyperactivation. They will use a mouse model of SLE to study the implication of BANK1 in B cell activation and effector function. Apart from fundamental insight into the pathophysiology of autoimmunity, results will pave the way towards novel therapeutic interventions.
Objective
Systemic Lupus Erythematosus (SLE, Lupus) is a life-threatening and incurable autoimmune disease that affects primarily women, its pathogenesis is related with an exaggerated B cells activation that results both in the generation of antibodies against self-nuclear acid antigens and in the generation of subsets of B cells that can exert antibody-independent roles in Lupus. However, the mechanisms that regulate aberrant B cell functions are poorly understood. In this project, we propose to investigate the role of the B cell scaffold protein with ankyrin repeats 1 (BANK1) in the B cell activation signaling pathways in a mouse model of Lupus. We have previously reported that the absence of BANK1 signaling in mice susceptible to Lupus resulted in the reduction of the activation of B cells, circulating total IgG2c and IgG autoantibodies, pro-inflammatory cytokines, and transcription factors related with TLR7 activation. Our data suggest that BANK1 is an important mediator of B cell hyperactivation. We hypothesize that BANK1 plays an important role in B cell signaling affecting their activation and effector functions in Lupus, however we do not fully understand yet the mechanism behind the function of BANK1. Our specific aims are: 1) to define how BANK1 signaling drives class switch recombination, 2) to determine the mechanism by which BANK1 regulates the cytokine production in B cells, and 3) to examine the participation of BANK1 signaling in the differentiation of pathogenic B cell subsets. To accomplish our objectives, we will use flow and mass cytometry, RNA-based next-generation sequencing (RNA-seq) analysis, the assay for transposase-accessible chromatin followed by deep sequencing (ATAC-seq), and a chromatin immunoprecipitation (ChIP) assay. We expect that the results of these studies will help to understand the molecular mechanism underlying the pathogenic B cell response in Lupus and will lead to identification of new avenues for therapeutic development.
