characterization of inflammatory responses during intranasal colonization with streptococcus pneumoniae

肺炎球菌による鼻咽頭コロニー形成は、肺または血流1に侵入する前提条件である。この生物は、鼻咽頭の粘膜表面を植民地化することができ、宿主の他の組織に侵入するために宿主防御を克服し、増殖し、最終的に克服することができる。通常下気道に感染を起こすと肺炎が生じる。あるいは、細菌は、高い死亡率2に関連する細菌血症を引き起こす血流に広がり得るか、またはそれ以外の場合は肺炎球菌性髄膜炎の発症に直接導く。鼻咽頭コロニー形成の運動学および免疫応答を理解することは、S.肺炎感染モデルの重要な側面である。
我々の鼻腔内コロニー形成のマウスモデルは、ヒトモデル3 から適応され、鼻咽頭4-7における宿主病原体応答の研究において複数の研究グループによって使用されている。モデルの最初の部分では 、S.肺炎 の臨床的分離株を使用して、ヒト成人のキャリッジイベントに似た自己制限細菌コロニー形成を確立する。本明細書で詳述される手順は、細菌接種の調製を含み、続いて鼻腔内投与経路を介して接種を送達することによってコロニー形成事象を確立する。居住マクロファージは、定常状態の間に鼻咽頭の主要な細胞型である。典型的には、未感染マウス8に存在するリンパ球はほとんど存在しないが、粘膜コロニー形成は、免疫応答とその後の宿主免疫細胞の動員をもたらす低位から高等級の炎症(細菌種および株の病原性に応じて)をもたらす。これらの細胞は、ナレスを通して気管内容物の洗浄によって単離され、感染の動態をよりよく理解するためにコロニー形成細菌の密度と相関することができる。

図 1 は、プロトコルの主要な手順を要約した概略図を示しています。 図2〜3は 、本明細書に記載されたプロトコルに固有の微生物学的方法論の可視化を提供する。 図4 は、鼻腔内コロニー形成を行うマウスの適切な位置を示し、図 5 は典型的に S.肺炎株 P1547でコロニー形成されたマウスの体重の変化を示している。 図6〜7は</str...
