Anti-Interleukin-5 (Mepolizumab) Therapy For Hypereosinophilic Syndromes

hypereosinophilic-syndromes
Interleukin-5 is the key cytokine in eosinophil differentiation and growth in the bone marrow and stimulates the release of eosinophils into the peripheral circulation. Thus, it is thought that IL-5 may be involved in the pathogenesis of hypereosinophilic syndromes (HES), a diverse group of poorly treated disorders characterized by sustained peripheral blood and/or tissue eosinophilia. Mepolizumab is a humanized monoclonal antibody to IL-5, and its safety and efficacy were assessed in this open-labelled trial. (more…)
