BAFF is a potent B-cell survival factor, and it plays an essential role in B-cell homeostasis and B-cell function in the periphery. Both normal and autoreactive B cells are BAFF dependent; however, excess BAFF promotes the survival, growth, and maturation of autoreactive B cells. When overexpressed, BAFF protects B cells from apoptosis, thereby contributing to autoimmunity. Three independent studies have shown higher BAFF levels in the circulation of MG patients. BAFF may play an important role in the pathogenesis of MG. BAFF antagonists may well provide new treatment options for MG patients, particularly those patients with thymic lymphoid follicular hyperplasia.

The association between COVID-19 and autoimmune diseases has gained increasing recognition, yet the specific targets of SARS-CoV-2-induced IgG are currently in focus for several studies. This study aims to explore the proteomic targets of these antibodies and their potential role in autoimmunity. We utilised a human proteome microarray encompassing 23 736 unique proteins, including isoform variants and fragments, as catalogued by the Human Protein Atlas.

A growing number of systemic hereditary inflammatory diseases characterized by periodic fevers and elevated acute-phase proteins during flares has been linked to deregulated inflammasome function and excessive bioactivity of interleukin (IL)-1. All these conditions respond, at varying degrees, to the specific blockade of IL-1. The remarkable progress with IL-1 antagonists in treating hereditary inflammasome-based disorders has offered new hope for several patients with further non-hereditary autoinflammatory conditions from multifactorial backgrounds.

ANCA vasculitis is a systemic autoimmune small-vessel vasculitis characterized by autoantibodies targeting either MPO or PR3. While patients with ANCA vasculitis are successfully treated with broad-spectrum immunosuppression, these treatments often leave patients vulnerable to infections. Research in the field has made positive gains in regards to understanding autoantigen specificity and immune cell subset involvement in disease pathogenesis, relapse and remission.

Introduction: Systemic lupus erythematosus (SLE) is characterized by dysregulated humoral immunity, leading to the generation of autoreactive B cells that can differentiate both within and outside of lymph node (LN) follicles.

Methods: Here, we employed spatial transcriptomics and multiplex imaging to investigate the follicular immune landscaping and the transcriptomic profile in LNs from SLE individuals.

Results: Our spatial transcriptomic analysis revealed robust type I IFN and plasma cell signatures in SLE compared to reactive, control follicles.

The SARS-CoV-2 pandemic, while subsiding, continues to plague the world as new variants emerge. Millions have died, and millions more battle with the debilitating symptoms of a clinical entity known as long Covid. The biggest challenge remains combating an ever-changing variant landscape that threatens immune evasion from vaccine and prior infection-generated immunity.
