Thymic stromal lymphopoietin is an established pleotropic alarmin cytokine that is generated at barrier tissues to induce type 2 immune responses, but its role in regulating the diversity of B cells is poorly understood. Here, we will highlight the key findings that underpin our limited understanding of the role thymic stromal lymphopoietin in modulating different stages of B cell development. We will also provide an overview of how thymic stromal lymphopoietin drives B cell-mediated immune disease and how novel thymic stromal lymphopoietin-blocking biologics could be used to modulate B cell responses. Thymic stromal lymphopoietin is critical for the regulation, diversity, and longevity of humoral immunity.
Keywords: B cells; cytokines; thymic stromal lymphopoietin.
