characterization of inflammatory responses during intranasal colonization with streptococcus pneumoniae

Streptococcus pneumoniae tarafından nazofarengeal kolonizasyon akciğerlere veya kan dolaşımına istilanın ön koşuludur1. Bu organizma, nazofarenksin mukozal yüzeyini kolonileştirebilir, burada konakçının diğer dokularına istila etmek için konak savunmalarını barındırabilir, çoğaltabilir ve sonunda üstesinden gelebilir. Normalde alt solunum yollarında bir enfeksiyonun kurulması zatürre ile sonuçlanır. Alternatif olarak, bakteriler kan dolaşımına yayılabilir ve yüksek ölüm oranları2ile ilişkili olan bakteriyemiye neden olabilir veya doğrudan pnömokok menenjitinin gelişmesine yol açabilir. Nazofarengeal kolonizasyonun kinetiğini ve immün yanıtlarını anlamak S. pneumoniae enfeksiyon modellerinin önemli bir yönüdür.
İntranazal kolonizasyon fare modelimiz insan modellerindenuyarlanmıştır 3 ve nazofarenks4-7konak-patojen yanıtlarının incelenmesinde birden fazla araştırma grubu tarafından kullanılmıştır. Modelin ilk bölümünde, insan yetişkinlerde taşıma olaylarına benzer, kendi kendini sınırlayan bir bakteri kolonizasyonu oluşturmak için S. pneumoniae'nin klinik bir izolesini kullanıyoruz. Burada ayrıntılı olarak açıklanan prosedür, bakteriyel bir inoculumun hazırlanmasını ve ardından inoculumun intranazal bir uygulama yolu ile teslim edilmesi yoluyla bir kolonileşme olayının kurulmasını içerir. Yerleşik makrofajlar, sabit durum sırasında nazofarenksteki baskın hücre tipidir. Tipik olarak, enfekte olmayan farelerde az sayıda lenfosit vardır8, ancak mukozal kolonizasyon, bağışıklık yanıtı ve daha sonra konak bağışıklık hücrelerinin işe alınmasıyla sonuçlanacak düşük ila yüksek dereceli inflamasyona (bakteri türlerinin ve suşunun virülansına bağlı olarak) yol açacaktır. Bu hücreler, nares yoluyla trakeal içeriğin bir lavajı ile izole edilebilir ve enfeksiyonun kinetiğini daha iyi anlamak için kolonizasyon bakterilerinin yoğunluğu ile ilişkilidir.

Characterization of Inflammatory Responses During Intranasal Colonization with Streptococcus pneumoniae

Murine nazofarenksin Streptococcus pneumoniae ile kolonizasyonu ve daha sonra yapışık veya işe alınan hücrelerin çıkarılması açıklanmaktadır. Bu teknik, nazofarenksin yıkanmasını ve sıvının nares yoluyla toplanmasını içerir ve diferansiyel hücre niceliği ve mRNA ekspresyonunun yerinde analizi dedahil olmak üzere çeşitli okumalar için uyarlanabilir.
