Inmunohistochemical Evaluation of Estrogen Receptors Alpha and Beta in Normal Inferior Turbinate Mucosa
It has been postulated that the nasal mucosa, like other human tissues, is affected by a complex interactive network of neuropeptides, cytokines, allergic and inflammatory mediators and hormones such as estrogen, in which associations between symptoms (e.g. nasal stuffiness and coryza) and hormonal...

| Sumario: | It has been postulated that the nasal mucosa, like other human tissues, is affected by a complex interactive network of neuropeptides, cytokines, allergic and inflammatory mediators and hormones such as estrogen, in which associations between symptoms (e.g. nasal stuffiness and coryza) and hormonal variations deriving from pregnancy, use of hormonal contraceptives and menstrual cycle phases are observed. The objective is evaluating the presence of specific estrogen receptors (types alpha and beta) in inferior turbinate mucosa in healthy subjects without nasal symptoms. Samples of nasal inferior turbinate were removed from patients undergoing aesthetic nasal surgery, and analyzed using hematoxylin-eosin staining, followed by immunohistochemical preparations on paraffin-embedded sections from the material sample, to detect estrogen receptors alpha and beta. Positive immunohistochemical reactions for both beta and alpha receptors were found in various regions of the inferior nasal turbinate. In conclusion both alpha and beta receptors were found, though the expression of beta was greater and more intense in the anterior portion of the inferior turbinate. No difference was found between male and female patients regarding the intensity of expression of receptors in the inferior turbinate. |
