Sensitivity to oxazolone induced dermatitis is transferable with gut microbiota in mice

Atopic Dermatitis (AD) has been associated with gut microbiota (GM) dysbiosis in humans, indicating a causative role of GM in AD etiology. Furthermore, the GM strongly correlates to essential disease parameters in the well-known oxazolone-induced mouse model of AD. Here, we demonstrate that it is possible to transfer both a high-responding and a low-responding AD phenotype with GM from conventi...

Gastrointestinal microbiota and local inflammation during oxazolone-induced dermatitis in BALB/cA mice.

At present, laboratory animals are not standardized with regard to the gastrointestinal microbiota (GM), but differences in this feature may alter various parameters in animal models. We hypothesized that variation in the GM correlated with variation in clinical parameters of a murine oxazolone-induced skin inflammation model of atopic dermatitis. BALB/cA mice were sensitized with oxazolone ov...

Gut Microbiota Dysbiosis Is Associated with Inflammation and Bacterial Translocation in Mice with CCl4-Induced Fibrosis

BACKGROUND Gut is the major source of endogenous bacteria causing infections in advanced cirrhosis. Intestinal barrier dysfunction has been described in cirrhosis and account for an increased bacterial translocation rate. HYPOTHESIS AND AIMS We hypothesize that microbiota composition may be affected and change along with the induction of experimental cirrhosis, affecting the inflammatory resp...

Topically applied azaphenothiazines inhibit contact sensitivity to oxazolone in mice.

In this work we investigated the efficacy of two topically applied azaphenothiazine derivatives, 9-chloro-6-acetylaminobutylquinobenzo[3,2-b][1,4]thiazine (compound 4) and 6-chloroethylureidoethyldiquino[3,2-b;2';3'-e][1,4]thiazine (compound 5), in the amelioration of inflammatory symptoms of contact sensitivity (CS) to oxazolone in mice, in relation to the commercial ointment Protopic® (tacrol...

Correlation of gut microbiota composition with colon adenomatous polyps

Microbiota is a collection of microorganisms that live in the oral cavity, respiratory tract and intestine of multicellular organisms. Microbiota exerts numerous physiological and pathological effects on the organism in which it resides. Increasing attention has been directed to the host-microbiota interaction, which is highly relevant to the development of carcinogenesis. Changes in the compos...
