IL-13 signaling via IL-13Rα2 triggers TGF-β1-dependent allograft fibrosis
BACKGROUND Allograft fibrosis still remains a critical problem in transplantation, including heart transplantation. The IL-13/TGF-β1 interaction has previously been identified as a key pathway orchestrating fibrosis in different inflammatory immune disorders. Here we investigate if this pathway is also responsible for allograft fibrosis and if interference with the IL-13/TGF-β1 interaction prev...
متن کاملTreatment of Experimental (Trinitrobenzene Sulfonic Acid) Colitis by Intranasal Administration of Transforming Growth Factor (Tgf)-β1 Plasmid
In this study, we show that a single intranasal dose of a plasmid encoding active transforming growth factor beta1 (pCMV-TGF-beta1) prevents the development of T helper cell type 1 (Th1)-mediated experimental colitis induced by the haptenating reagent, 2,4, 6-trinitrobenzene sulfonic acid (TNBS). In addition, such plasmid administration abrogates TNBS colitis after it has been established, wher...
متن کاملProtective effect of royal jelly in 2,4,6 trinitrobenzene sulfonic acid-induced colitis in rats
Objective(s):In the present study, we evaluated immunological and immunomodulatory properties of royal jelly (RJ) in 2,4,6 trinitrobenzene sulfonic acid (TNBS)-induced colitis in rats. Materials and Methods: Eighteen adult female Wistar albino rats were divided into three groups of six animals each: a control group that received only saline solution, a TNBS-induced colitis group, and a TNBS-co...
متن کاملGlutamine prevents fibrosis development in rats with colitis induced by 2,4,6-trinitrobenzene sulfonic acid.
We investigated the effects of glutamine on the development of colonic fibrosis and on the expression of the major fibrogenic factors in a rat model of experimental colitis. Colitis was induced in one-half of the male Wistar rats by intracolonic administration of 30 mg of 2,4,6-trinitrobenzene sulfonic acid (TNBS). L-glutamine (25 mg/kg) was administered rectally to one-half of the controls and...
متن کاملvalidation and optimization of experimental colitis induction in rats using 2, 4, 6-trinitrobenzene sulfonic acid
trinitrobenzene sulfonic acid (tnbs)-induced colitis is one of the most common methods for studying inflammatory bowel disease in animal models. several factors may, however, affect its reproducibility, rate of animal mortality, and macroscopic and histopathological outcomes. our aim was to validate the main contributing factors to this method and compare the effects of different reference drug...
