If there is any later exposure to the same allergen, the allergen can bind to the IgE molecules heldon the surface of the mast cells. Cross-linking of the IgE and FcεRI occurs when more than one IgE-receptor complex interacts with the same allergenic molecule, and activates the sensitized cell, triggering a signal transduction pathway. Activated mast cells undergo a process called degranulation, during which they release histamine and other inflammatory chemical mediators including proteoglycans, proteases, leukotrienes, prostaglandins and cytokines, which are already present or synthesized anew, from their granules into the surrounding tissue, causing several allergic reactions, such as vasodilation, nerve stimulation, mucous secretion, and smooth muscle contraction. |

| 如果有任何之后暴露的相同過敏原,則過敏原可結(jié)合IgE分子附著在肥大細(xì)胞的表面上。當(dāng)一個(gè)以上的IgE受體復(fù)合物與相同的過敏分子相互作用時(shí),IgE 和FcεRI產(chǎn)生交聯(lián),并激活致敏細(xì)胞,激起信號(hào)轉(zhuǎn)導(dǎo)通路。激活肥大細(xì)胞的過程稱為脫顆粒,是肥大細(xì)胞從他們的顆粒中向周圍組織釋放已有或者重新合成的組胺以及其他炎癥化學(xué)媒介包括蛋白聚糖、蛋白酶、白細(xì)胞三烯、前列腺素和細(xì)胞激素的過程,引起若干炎癥反應(yīng),比如血管舒張、神經(jīng)刺激、粘液分泌以及平滑肌收縮。 |
