Sažetak


Cilj ovog istraživanja je bio da se ispita potencijal imunostimulišućeg soja Limosilactobacillus fermentum BGHI14 da smanji oštećenje tkiva debelog creva kod pacova sa kolitisom izazvanim 2,4,6-trinitrobenzensulfonskom kiselinom (TNBS). Pacovi Wistar soja su tretirani sojem L. fermentum BGHI14 u režimu preventivnog, terapijskog i kontinuiranog tretmana 22 dana pre i/ili 7 dana nakon primene TNBS. Nakon žrtvovanja, uzorci debelog creva su sakupljeni za izolaciju RNK, analizu ekspresije gena, histopatološke analize i merenje malondialdehida. Na osnovu telesnih težina pacova, histopatološih rezultata, nivoa malondialdehida i transkripcije IL-1β citokina i proteina tesnih međućelijskih veza (Tjp-1), preventivni i terapijski tretman su se pokazali kao najefikasniji u primenjenim uslovima. S druge strane, kontinuirano lečenje nije uticalo na intenzitet oštećenja tkiva. Uzimajući u obzir ove rezultate, razmotreni su mogući mehanizmi koji stoje iza zaštitnog delovanja imunostimulišućih probiotičkih bakterija u slučaju oštećenja mukozne barijere.
