After correction for spontaneous release, the induced release of histamine, LTC4/D4/E4 and PGD2 was significantly higher in the nasal polyp group compared to the inferior turbinate group, both after stimulation with anti-IgE 10 μg/ml and anti-IgE 30 μg/ml (Fig 1). The gene discussed is IGHE; the disease is Nasal polyposis.
