Sumario: | Obesity is associated with chronic inflammation of various tissues including visceral adipose tissue (VAT), which contributes to insulin resistance. T cells and macrophages infiltrate VAT in obesity and orchestrate this inflammation. Recently, we made the surprising discovery that B cells are important contributors to this process. Thus, some B cells and the antibodies they produce can promote VAT-associated and systemic inflammation, leading to insulin resistance. This report will focus on the properties of these B cells, and how they contribute to insulin resistance through T-cell modulation and production of pathogenic autoantibodies. Understanding the mechanisms by which B cells contribute to insulin resistance should lead to new antibody-based diagnostics and B-cell modulating therapeutics to manage this increasingly prevalent disease. |
