Anotace v anglickém jazyce\n\nMouse model of human psoriasis and gnotobiotic are important tools in understanding the role of gut and skin microbiota in pathogenesis of psoriasis. In our experiments we showed that gnotobiotic mice, as well as conventional mice treated with antibiotics, have milder skin inflammation in comparison with control conventional mice. Treatment with broad spectrum antibiotics led to dramatic shift in gut microbial composition, in particular, we observed extensive increase of order Lactobacillales. To analyze the potential effect of Lactobacillales on skin inflammation, we further monocolonized mice with L. plantarum WCFS1. Also monocolonized mice showed lower skin inflammation in comparison with conventional mice. To understand whether microbial dysbiosis is cause or effect of psoriasis needs to be further investigated.\n\n
