Most B-cell-related disorders can be cured with conventional agents; however, relapse is common, creating a need for additional therapeutic options. In agreement, recent biomarker studies corroborate the role played by functional crosstalk between malignant B cells and microenvironment which have added texture to clinical outcome. Here we outline the essential role of the tumor-associated niche in B-cell Lymphoma/Leukemia pathogenesis, in an attempt to optimize the use of microenvironment-targeted drugs and anti-CD20 antibodies in the various subsets.

Introduction: Wound healing causes heavy economic burdens for families and society, becoming a critical issue in the global healthcare system. While the role of immune cells in the wound healing process is well-established, the involvement of B cells remains poorly understood. This study aims to elucidate the essentiality of B cells in wound repair.

Background And Objectives: Hepatitis B vaccination (HBV) requires 6 months to complete and is recommended for patients with multiple sclerosis (PWMS), particularly those who are candidates for anti-CD20 therapy. However, limited data exist on HBV immunogenicity in PWMS receiving disease-modifying therapies (DMTs) and the impact of starting anti-CD20 therapy during immunization. We aimed to evaluate HBV immunogenicity in PWMS starting anti-CD20 therapy during vaccination, focusing on the number of doses received before anti-CD20 initiation.

Background And Objectives: Gut microbial symbionts have been shown to influence the development of autoimmunity in multiple sclerosis (MS). Emerging research points to an important relationship between the microbial-IgA interface and MS pathophysiology. IgA-secreting B cells are observed in the MS brain, and shifts in gut bacteria-IgA binding have been described in some patients with MS.

Posterior reversible encephalopathy syndrome (PRES) is an uncommon neurological condition characterized by reversible subcortical vasogenic edema that primarily affects the posterior areas of the brain. Subcortical vasogenic edema resulting from endothelial injury and hypertension is the pathogenesis. Here, we present a 23-year-old female patient with systemic lupus erythematosus (SLE) and lupus nephritis who developed PRES following Rituximab (a monoclonal anti-CD-20 antibody) administration.

Autoimmune diseases arise from immune system dysfunction that immune cells mistakenly attack the body's own tissues, resulting in systemic disorders or localized lesions such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Autoreactive B cells play a critical role in the pathogenesis of many autoimmune diseases and B cell depletion using anti-CD20 monoclonal antibody (mAb) has been shown to effectively mitigate disease progression in both preclinical and clinical studies. Recently, bispecific antibody (bsAb) targeting CD20/CD3 have demonstrated substantial clinical benefits in the treatment of various hematologic malignancies.
