trichuris muris infection: a model of type 2 immunity and inflammation in the gut

鞭muris是一个自然的小鼠的病原体和鞭虫物种感染人类和牲畜 1的生物学和抗原性相似。感染性虫卵经口灌胃，在远端小肠孵化，侵入肠上皮细胞（IECS），该行盲肠和近端结肠隐窝和成熟后的蠕虫释放到环境中的鸡蛋1。这个模型是一个功能强大的工具来检查因素控制的CD4 +辅助性T细胞（TH）的激活，以及在肠上皮细胞的变化。免疫反应的抗近交系C57BL / 6和BALB / C，如发生的特点，是由Th2细胞极化的细胞因子（IL - 4，IL - 5和IL - 13）和驱逐的蠕虫病毒，而Th1相关的细胞因子（IL -12，IL - 18，IFN -γ）促进在遗传易感性的AKR / J 小鼠 2-6的慢性感染。 Th2细胞因子，促进生理肠道微环境的变化，包括IECS的快速周转，杯状细胞的分化，招聘和上皮通透性和平滑肌收缩，所有这一切都已经在蠕虫驱逐7-15牵连的变化。在这里，我们详细为传播鞭muris可以在随后的实验中使用的鸡蛋的的协议。我们还提供了为感染后的分析建议的样品实验收获。总体而言，该协议将提供的基本工具的研究人员，执行鞭muris小鼠感染模型，它可以用来解决有关的问题在胃肠道以及免疫效应功能的IECS钍倾向。
