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

Trichuris muris farelerin doğal bir patojen ve enfekte insanlar ve hayvancılık 1 Trichuris türleri biyolojik ve antijenik olarak benzer . Enfektif yumurta ağızdan sonda ile distal ince bağırsakta ambar tarafından verilen, çizgi çekum ve proksimal kolon ve olgunlaşma üzerine kript solucanlar ortamı içine 1 yumurta serbest intestinal epitel hücrelerinde (IECS) işgal. Bu model faktörleri incelemek için güçlü bir araç olduğunu kontrol CD4 + T helper (Th) hücre aktivasyonu yanı sıra bağırsak epitel değişiklikleri. C57BL / 6 ve BALB / c gibi dayanıklı kendilenmiş suşları, ortaya çıkan immün yanıt, polarize Th2 sitokinlerin (IL-4, IL-5 ve IL-13) ve ilişkili Th1 sitokinlerin iken (IL solucanlar sürülmesi ile karakterizedir -12, IL-18, IFN-γ) kronik enfeksiyonlar, genetik olarak yatkın AKR / J fareler 2-6 teşvik . Th2 sitokinleri hızlı IECS ciro, goblet hücre farklılaşması, işe alma ve epitelyal permeabilite ve düz kas kasılması, solucan sınırdışı 7-15 suçlanmıştır hangi değişiklikler dahil olmak üzere bağırsak mikroçevresinin fizyolojik değişiklikler teşvik eder. Burada detay Trichuris muris yumurta sonraki deneylerde kullanılan propaganda için bir protokol. Ayrıca enfeksiyon sonrası analizi için önerileri ile örnek bir deneysel hasat sağlar. Genel olarak, bu protokol, gastrointestinal sistem gibi IECS immün efektör fonksiyonları Th eğilimine ilişkin soruları yanıtlamak için kullanılabilecek bir Trichuris muris fare enfeksiyon modeli gerçekleştirmek için temel araçları araştırmacılar sağlayacaktır .
