Cefdinir Microsphere Modulated Microflora and Liver Immunological Response to Diet Induced Diabetes in Mice

Colonic Microflora Protagonist of Liver Metabolism and Gut Permeability: Study on Mice Model

Alteration of gut microflora results in a metabolic imbalance in the liver. In the present study, we investigate the reversal potential of alteration of the colonic microflora via improving metabolism balance and regulating the altered tight junction of the intestinal tract. Animals were fed with high sugar diet to mimic the onset of the pathophysiological conditions of diabetes. Following induction, animals were divided into two reversal groups i.e., crude cefdinir and colon-specific formulated cefdinir, to alter the gut microflora. In the present study, we have tried to quantify the microbial content via metagenome analysis to provide an actual picture of the alteration and subsequent reversal. Expression of mRNA of junctional protein and parameters involved in liver metabolism was determined using qPCR. Results indicated direct effect of altered composition of gut microflora on the gut permeability and metabolic alteration. Metagenomic analysis showed least evenness and richness in the HSD group whereas antibiotic-treated groups showed reversal of microflora towards control group with increased richness, evenness and decreased distance on PCoA plot. This changes in gut microflora composition changes expression of metabolic markers and thus insulin sensitivity. Targeting colonic microflora to have a reversal effect on T2D pathogenesis, found to have a positive impact on liver metabolic state with improved permeability markers of gut with SCFA alteration.
