[Regulatory B cells in human autoimmune diseases]

Area of Science:

• Immunology
• Cell Biology

Context:

• B cells traditionally viewed as immune response promoters.
• Autoimmune diseases linked to B cell dysfunction.
• Discovery of regulatory B cell subsets in mouse models.

Purpose:

• To review current knowledge on regulatory B cells (Bregs) in human autoimmune diseases.
• Focus on IL-10-producing Bregs and their clinical relevance.

Summary:

• Regulatory B cells (Bregs) negatively regulate immune responses, contrasting with traditional B cell functions.
• IL-10-producing Bregs are the most studied subset, with growing evidence in human diseases.
• Human Bregs are a key area of research, particularly in autoimmune conditions.

Impact:

• Understanding human Bregs' immune regulation mechanisms is vital.
• Potential for developing novel B cell-targeted therapies for autoimmune diseases.
• Highlights current clinical research on human Bregs using human samples.
