Classical Hodgkin lymphoma (cHL) is characterized histologically by a minority of malignant Hodgkin Reed-Sternberg cells surrounded by abundant inflammatory cells, generally believed to be of major importance in the pathophysiology of the disease. Here, we present data that link inflammatory cell-derived arachidonic acid metabolites, the cysteinyl leukotrienes (CysLT), to the pathogenesis of cHL. Two HL cell lines, L1236 and KMH2, were shown to express functional CysLT(1) receptors, responding with a robust calcium signal upon leukotriene (LT) D-4 challenge. LTD4 stimulated protein release of tumor necrosis factor-alpha, interleukin-6 and -8 by L1236 cells and interleukin-8 by KMH2 cells. Importantly, all these LTD4-induced effects were blocked by the CysLT(1) receptor-specific antagonist zafirlukast. Immunohistochemical studies of cHL biopsies and microarray analysis of microdissected cells revealed that the CysLT(1) receptor is expressed also by primary Hodgkin Reed-Sternberg cells. As these cells are surrounded by CysLT-producing eosinophils, macrophages and mast cells, our results suggest the CysLTs as mediators in the pathogenesis of cHL, contributing to the aberrant cytokine network of this lymphoma.
