眼变态反应是眼科医生最常见到的外眼疾病。各种变态反应性结膜炎的发病机制均是在眼睑与结膜中出现大量肥大细胞,后者是眼变态反应的基本炎症细胞。肥大细胞在其颗粒中含有预先合成的炎症介质(如组胺)。在细胞激活时合成的其它炎症介质包括前列腺素和白三烯。当肥大细胞表面的IgE分子与抗原结合时,激活肥大细胞释放炎症介质。这
Eye allergy is the most common eye disease seen by ophthalmologists. A variety of allergic conjunctivitis pathogenesis is in the eyelids and conjunctiva in a large number of mast cells, the latter is the basic inflammation of the eye inflammatory cells. Mast cells contain presynthesized inflammatory mediators (such as histamine) in their granules. Other inflammatory mediators that are synthesized upon cellular activation include prostaglandins and leukotrienes. When the IgE molecules on the surface of mast cells bind to the antigen, the mast cells are activated to release the inflammatory mediators. This
