저자는 연쇄상 구균 폐렴의임상 긴장의 그의 선물에 대한 펜실베니아 대학의 박사 제프리 와이저에게 감사드립니다. 이 연구는 건강 연구를 위한 캐나다 학회에 의해 투자되었습니다. 이력서는 M. G. DeGroote 펠로우십과 캐나다 흉부 학회의 펠로우십에 의해 지원되었습니다. 이 작품은 온타리오 폐 협회와 건강 연구의 캐나다 연구소 (CIHR)에 의해 투자되었다. 보우디시 실험실에서 일하는 것은 감염증 연구를 위한 마이클 G. DeGroote 센터 및 맥매스터 면역학 연구 센터에 의해 부분적으로 지원됩니다.

시작하기 전에: 모든 단계는 달리 명시되지 않는 한 생물 적 위험 수준 2 (BSL2) 생물 안전 캐비닛 (BSC)에서 수행됩니다. 실험 개시 전에 기관 지침에 따라 전염성 세균 병원균의 사용에 대한 적절한 생체 위험 승인을 획득했습니다. 또한 사전에 준비된 절차를 수행하는 데 필요한 모든 재료와 시약이 있는지 확인하십시오. 이 실험에 사용된 마우스는 잭슨 연구소, 찰스 강 또는 타코닉에?...

characterization of inflammatory responses during intranasal colonization with streptococcus pneumoniae

연쇄상 구균 폐렴에 의한 비인두 식민지는 폐 또는 혈류량1에침입하는 전제 조건이다. 이 유기체는 비소하린의 점막 표면을 식민지화 할 수 있으며, 여기서 호스트 방어를 극복하고 호스트의 다른 조직에 침입할 수 있습니다. 일반적으로 낮은 호흡기에 감염의 설립은 폐렴귀착됩니다. 대안적으로, 박테리아는 높은 사망률2와연관되는 박테혈증을 일으키는 혈류로 전파할 수 있고, 또는 그렇지 않으면 폐렴구균 수막염의 발달로 직접 이끌어 낼 수 있다. 비인두 식민지의 운동 및 면역 반응을 이해하는 것은 S. 폐렴 감염 모델의 중요한 측면입니다.
비강 내 식민지화의 마우스 모델은 인간모델3로부터 적응하고 비소하린4-7의 숙주 병원체 반응 연구에서 여러 연구군에 의해 사용되어 왔다. 모델의 첫 번째 부분에서, 우리는 인간 성인의 운송 이벤트와 유사한 자기 제한 세균 성 식민지를 확립하기 위해 S. 폐렴의 임상 분리를 사용합니다. 본명 상세절차는 세균성 접종의 준비를 포함하고, 그 다음에는 행정의 비강 내 경로를 통해 접종의 전달을 통해 식민지화 사건의 수립을 포함한다. 상주 대식세포는 정상 상태 동안 비소하린의 주요 세포 유형이다. 전형적으로, 감염되지 않은 마우스에 존재하는 몇몇 림프구가8,그러나 점막 식민지는 면역 반응 및 호스트 면역 세포의 후속 모집귀착될 낮은- 고급 염증 (세균성 종 및 긴장의 독성에 따라 다름)으로 이끌어 낼 것입니다. 이러한 세포는 나레를 통해 기관 내용물의 용암에 의해 격리될 수 있으며, 감염의 운동학을 더 잘 이해하기 위해 식민지 박테리아의 밀도와 상관관계가 있다.
