Guardians at the Interface: Microbiota, Intestinal Barriers, and the Gut–Liver Axis in Liver Health and Disease

ABSTRACT A wide variety of diseases and conditions can affect liver health. Irrigational microbiota and their metabolites are implicated in gut permeability and the development of liver disease, although the exact pathways are still poorly known. Bacterial lipopolysaccharide (LPS) causes changes in Toll‐like receptor signaling associated with leaky gut syndrome, according to animal research. Liver illness in humans has also been linked to changes in intestinal permeability caused by microbiota. A lot of different approaches to treating liver disease are being considered right now. Research into the processes by which microbiota might modify the intestinal barrier and hence contribute to the development and progression of liver disease is summarized and discussed in this review, along with the primary techniques now under consideration for the management of these diseases. Here, we focus on lifestyle modifications (such as increased physical activity and a healthier diet) and probiotic intervention as methods that have improved the composition of the gut microbiota (GM) and the function of the intestinal barrier. However, the precise processes at work are unclear, and our understanding of the ways in which these alterations are advantageous is currently restricted. That is why we need more investigations into animals and humans, as well as in vitro.
