Predicting and monitoring colitis development in mice by micro-computed tomographyMaria Fritsch Fredin
Department of Integrative Pharmacology, AstraZeneca R and D Molndal, Molndal, Sweden
Inflamm Bowel Dis 14:491-9. 2008..The aim of this study was to evaluate colon wall thickness as a noninvasive marker in the dextran sodium sulfate (DSS) mouse model of colitis using micro-CT...
Local production of chemokines and prostaglandin E2 in the acute, chronic and recovery phase of murine experimental colitisSilvia Melgar
Department of Integrative Pharmacology, AstraZeneca R and D Molndal, GI Biology, SE 431 83, Sweden
Cytokine 35:275-83. 2006..Thus, our results show that chemokines are produced in a dynamic manner during colitis progression...
Acute colitis induced by dextran sulfate sodium progresses to chronicity in C57BL/6 but not in BALB/c mice: correlation between symptoms and inflammationSilvia Melgar
AstraZeneca R and D Molndal, Dept of Integrative Pharmacology, GI Biology, SE 431 83 Molndal, Sweden
Am J Physiol Gastrointest Liver Physiol 288:G1328-38. 2005..We believe that the present protocol to induce chronic colitis in C57BL/6 mice offers a robust model for validating future therapies for treatment of inflammatory bowel disease...
Mice with experimental colitis show an altered metabolism with decreased metabolic rateSilvia Melgar
Department of Integrative Pharmacology, Gastrointestinal Biology, AstraZeneca Research and Development, Molndal, Sweden
Am J Physiol Gastrointest Liver Physiol 292:G165-72. 2007..These observations suggest compensatory metabolic alterations in chronic colitis resulting in a healthy appearance despite gross colon pathology...
High-throughput magnetic resonance imaging in murine colonic inflammationSilvia Melgar
Department of Integrative Pharmacology, AstraZeneca, Molndal, Sweden
Biochem Biophys Res Commun 355:1102-7. 2007....
Validation of murine dextran sulfate sodium-induced colitis using four therapeutic agents for human inflammatory bowel diseaseSilvia Melgar
Department of Integrative Pharmacology, AstraZeneca R and D Molndal, Sweden
Int Immunopharmacol 8:836-44. 2008..Thus, three of the current tested agents showed efficacy in the disease model, arguing that DSS-induced colitis can be used as a relevant model for the translation of mice data to human disease...
Intra-colonic administration of the TLR7 agonist R-848 induces an acute local and systemic inflammation in miceAgneta Karlsson
Department of Integrative Pharmacology, AstraZeneca R and D Molndal, Sweden
Biochem Biophys Res Commun 367:242-8. 2008..We suggest that the R-848 inflammatory model can be useful in future validation of new drugs for gastrointestinal inflammatory conditions...
Dextran sulphate sodium induces acute colitis and alters hepatic function in hamstersAgneta Karlsson
Department of Integrative Pharmacology, AstraZeneca R and D Molndal, Sweden
Int Immunopharmacol 8:20-7. 2008..In addition, DSS-exposed hamster showed alterations in hepatic fatty acids metabolism resembling human IBD, suggesting that the model can potentially be used for target discovery and validation of hepatic-related metabolic alterations...
Magnetic resonance imaging of experimental mouse colitis and association with inflammatory activityAnna E Larsson
DECS Imaging, AstraZeneca R and D Möldnal, Molndal, Sweden
Inflamm Bowel Dis 12:478-85. 2006..The aim of the present study was to investigate the role of MRI in quantitatively reflecting inflammation in an experimental mouse colitis model...
The application and relevance of ex vivo culture systems for assessment of IBD treatment in murine models of colitisMaria Fritsch Fredin
Department of Bioscience at AstraZeneca R and D Mölndal, Sweden
Pharmacol Res 58:222-31. 2008....
Anti-inflammatory effects of budesonide in intestinal epithelial cellsMaria Fritsch Fredin
Department of Integrative Pharmacology, AstraZeneca AB, R and D Mölndal, Molndal, Sweden
Pharmacol Res 52:422-8. 2005..We conclude that budesonide exert an anti-inflammatory effect directly on intestinal epithelial cells, which may contribute to the overall action of budesonide in the treatment of inflammatory bowel diseases...
Human small intestinal mucosa harbours a small population of cytolytically active CD8+ alphabeta T lymphocytesSilvia Melgar
Department of Immunology, , Ume, Sweden
Immunology 106:476-85. 2002..The observed Fas/FasL-mediated cytotoxicity may be a reflection of ongoing down-regulation of local immune responses by 'activation-induced cell death'...
