Recent studies have suggested the involvement of cysteinyl leukotrienes (CysLTs) in nasal polyp development. To further understand the role of CysLTs in polyp pathogenesis, we studied the expression of CysLT1 receptors in nasal polyps.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>The study group comprised polyps removed endoscopically from 20 consecutive patients. Samples of ethmoid mucosa from 4 patients who underwent orbital decompression for Graves' ophthalmopathy were used as controls. The presence of CysLT1 receptors was determined with a rabbit anti-human anti\u2013CysLT1 receptor polyclonal antibody. Cells with and without CysLT1 receptor expression were counted within the epithelial layer and stroma by means of light microscopy (40\u00d7 magnification).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      There were significantly more cells expressing CysLT1 receptors in the stroma than in the epithelium in both nasal polyps and control specimens.
