CYSLTR1 and Hodgkins lymphoma: The same study group further assessed biopsy specimens from 29 Hodgkin lymphoma patients with immunohistochemical studies and assessed the micro-dissected Hodgkin Reed–Sternberg cells with microarray analysis, showing that CysLT1R was expressed by primary Hodgkin Reed–Sternberg cells, which were surrounded by CysLT-producing eosinophils, macrophages and mast cells; the findings might suggest that CysLTs were important mediators in the pathogenesis of Hodgkin lymphoma, contributing to the aberrant cytokine network [43].
