Forskning i Bragonzi laboratorium er finansieret af den italienske cystisk fibrose Foundation (CFaCore) og EU-F7-2009 til 223.670. En del af dette arbejde blev udført i Alembic, en avanceret mikroskopi laboratorium og mus histopatologi blev udført i Enheden for Patologisk Anatomi (San Raffaele Scientific Institute).

De kritiske trin i P. aeruginosa-perler forberedelse og mus udfordring er angivet nedenfor. P. aeruginosa-stamme for mus udfordring er kritisk. Dødelighed, kronisk infektion eller clearance kan variere betydeligt afhængigt af den anvendte bakteriestamme til udfordringen. P. aeruginosa RP73 klinisk stamme blev foretrukket frem for den PAO1 referencelaboratorium stamme, da det resulterede i en forholdsvis lavere dødelighed, mere alvorlige læsioner, og højere kro...

Cystisk fibrose (CF) er en genetisk sygdom er forårsaget af mutationer i cystisk fibrose transmembran konduktans regulator (CFTR)-gen. Dette gen koder for et chlorid kanal udtrykkes på membranen af ​​de fleste epitelceller. Bronchiectasia, slim plukker og parenchymal ødelæggelser forårsaget hovedsageligt af Pseudomonas aeruginosa-infektioner gradvist føre til alvorlig lungesygdom og dødelighed i de fleste af CF-patienter 1. Forståelse CF patogenese og videreudvikling af nye behandlingsformer afhængige dyremodel med karakteristiske træk ved CF. Adskillige mus, genetisk modificerede for CFTR-genet, er blevet genereret, men begrænsninger i evnen af disse arter rekapitulere CF-lignende lungesygdom og flere andre organer abnormiteter set i CF-patienter er blevet dokumenteret i vid udstrækning 2. Udvikling af infektion er en af ​​de store udfordringer i CF dyremodel. Litteraturen cltidligt tyder på, at der kan opnås en kronisk infektion, der varer mere end en måned kun hvis mus podes med bakterier er indlejret i en immobiliserende middel, såsom agar, agarose, eller tang alginat 3-5. Disse immobiliseringsmidler give mikroaerobe / anaerobe betingelser, som tillader bakterier til at vokse i form af mikrokolonier i lighed med vækst i slim i CF-patienter 6. Denne model af kronisk infektion fører til vedvarende bakterier i lungerne forårsager betændelse i luftvejene og skader 7. Men afhængigt af den anvendte metode bakteriestammen og dosis inokuleret i lungerne, kan procentdelen af ​​kroniske inficerede mus og bakteriebelastning genfundet i lungerne ved forskellige tidspunkter forskellige. Især den største udfordring for en langsigtet kronisk infektion er fortsat den lave bakterielle byrde ved P. aeruginosa og den lave procentdel af inficerede mus uger efter udfordring, hvilket indikerer that bakterieceller progressivt ryddet af værten. Ved at vælge P. aeruginosa RP73 klinisk stamme fra en samling af CF isolerer 8 vi succes opnået lav dødelighed, mere alvorlige læsioner, og høj procentdel af kronisk infektion med en stabil bakteriel belastning op til en måned i C57Bl/6NCrl mus. Dette papir beskriver den metode til at indlejre P. aeruginosa i agaren perler, vi har inficeret mus ved intratrakeal instillation, målt den bakterielle belastning og cytokiner i lungerne, indsamlet BAL væske og udført histologisk undersøgelse. Samlet set vil dette protokol hjælpe forskere i håndteringen fundamentalt vigtige spørgsmål om patogenese 8,9 og teste nye behandlingsformer mod P. aeruginosa kronisk infektion 10,11.

long term chronic pseudomonas aeruginosa airway infection in mice

En musemodel af kronisk luftvejs infektion er et vigtigt aktiv i cystisk fibrose (CF) forskning, selv om der er en række problemstillinger i forbindelse selve modellen. Tidlige faser af inflammation og infektion er ofte blevet undersøgt ved hjælp af Pseudomonas aeruginosa agar-beads musemodel, mens kun få rapporter har fokuseret på den langsigtede kronisk infektion in vivo. Den største udfordring for langsigtet kronisk infektion er fortsat den lave bakterielle byrde ved P. aeruginosa og den lave procentdel af inficerede mus uger efter udfordring, hvilket indikerer, at bakterieceller gradvis er ryddet af værten. Denne artikel præsenterer en metode til at opnå en effektiv langsigtet kronisk infektion i mus. Denne metode er baseret på indlejring af P. aeruginosa kliniske stammer i agar-beads in vitro, efterfulgt af intratracheal instillation i C57Bl/6NCrl mus. Bilateral lunge infektion er forbundet med sevrelle målbare udlæsning, herunder vægttab, dødelighed, kronisk infektion, og inflammatorisk reaktion. P. aeruginosa RP73 klinisk stamme blev foretrukket frem for den PAO1 referencelaboratorium stamme, da det resulterede i en forholdsvis lavere dødelighed, mere alvorlige læsioner, og højere kronisk infektion. P. aeruginosa kolonisering kan vare i lungerne i over tre måneder. Murine lunge patologi ligner CF-patienter med fremskreden kronisk lungesygdom. Denne musemodel mest nøje efterligner løbet af sygdomme hos mennesker og kan bruges både til undersøgelser af patogenesen og for evaluering af nye terapier.

Når protokollen er udført korrekt, P. aeruginosa agar-perler vil måle mellem 100-200 um og kan iagttages med en inverteret lysmikroskop ved pipettering et lille volumen af agar-perler suspension på et dias. Single bakterieceller er synlige i agar perler, som vist i detaljer i figur 1.. Valget af P. aeruginosa stamme anvendes i fremstillingen agar-perlerne er kritisk. Figur 2 og tabel 1 viser de data, der er opnået som ...
