AbstractUlcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) induced by dysregulation of the immune response in the intestinal mucosa. Although the underlying mechanisms of UC development are not fully understood, disruption of gut microbiota, “dysbiosis”, is thought to lead to the development of IBD. Persimmon (Ebenaceae Diospyros kaki Thunb.)-derived tannin, which is a condensed polymeric tannin consisting of catechin groups, has antioxidant, anti-inflammatory, and antimicrobial activities. In this study, we assessed the effect of persimmon-derived tannin on a murine model of UC established by dextran sulfate sodium-induced colitis in female mice. Dietary supplementation of tannin significantly decreased disease activity and colon inflammation. A hydrolysate of tannin directly suppressed expression of inflammatory genes in macrophages in vitro. In faecal microbiota, the relative abundance of Bacteroides was increased significantly by tannin supplementation. Alpha-diversity indices in colitis-induced mice were significantly higher in the tannin diet group compared with the control diet group. Additionally, expansion of Enterobacteriaceae and Enterococcus, which is associated with disease progression of IBD, was remarkably suppressed in the tannin diet group. These results suggest that persimmon-derived tannin ameliorates colon inflammation in UC through alteration of the microbiota composition and immune response, which may be a promising candidate for IBD therapy.

Key Points Gene polymorphism of the immune response as CTLA4 was shown to impact CBT outcomes according to CBU genotype. CTLA4-CBU genotype might be considered for CBU selection when >1 CBU meeting the current suggested selection criteria is available.

Aim. To study radiological features of pulmonary tuberculosis according to the polymorphism of the gene HLA-DRB1. Materials and methods. Radiologically examined 73 newly diagnosed patients with different clinical forms of pulmonary tuberculosis and genotyped for HLA-DRB1 by PCR-MSSR. Results. The analysis of associations specificities gene HLA-DRB1* depending on the x-ray picture of the disease. It is found that the specificity (*04, *11, *13, *14 and *16 gene HLA- DRB1 *) positively associated with the amount of a specific process for more than three segments and destruction of lung tissue. Genotypes with 01*, 07*, 08*, 10*, 12*, 15* and 16* specificities HLA- DRB1* lesion volume were less than three segments, with a predominance of productive inflammation of the lung tissue. Conclusions. X-ray picture of the 60.3% of patients with newly diagnosed pulmonary tuberculosis characterized by common (equity, polysegmental) lesions of the lung tissue. The obtained results of the study of gene polymorphism immune response HLA- DRB1*, show some specificity, in particular *04, *11, *13 and *16 alleles of HLA-DRB1*, possibly responsible for massive infiltration and destruction of lung tissue.
