CHANGES IN BALANCE OF T-HELPER SUBSETS IN THE GALT OF RATS UNDER CHRONIC ZOOSOCIAL STRESS AND MODULATION OF THE INTESTINAL MICROFLORA

It was investigated the influence of chronic zoosocial stress (ZSS) and modulation of the intestinal microflora composition on the ratio of T-helper subsets in GALT. It has been established that ZSS development was accompanied by an imbalance Tbet+/Gata3+- and Foxp3 +/Roryt +-cells, indicating the dominance of Th1- and Th17-differentiation and increasing levels of pro-inflammatory signaling in the gut. It was shown that the introduction of kanamycin to the stressed rats leads to the dominance of Th1- and Treg subsets, but modulation of the intestinal microflora lactobacterine reduces the ratio of Tbet +/Gata3 + - lymphocytes in the own lamina of mucous membrane of the fibres, increases in subepithelial zone and increases unidirectionally the ratio of Treg/Th17.
