摘要： We investigated the gut-kidney interaction in goslings with gout and tried to decipher the probable mechanisms through which gut dysbiosis leads to the progression of renal injury and inflammation. A total of 15 goslings (Anser cygnoides), with typical visceral gout symptoms, were screened and compared with 15 healthy goslings. We determined the signatures of the microbiome in the cecum chyme of goslings in the 2 groups by 16S sequencing, and analyzed the changes in intestinal permeability, levels of serum lipopolysaccharide (LPS), and the induced inflammatory response of Toll-like receptors (TLRs). We found the existence of gut dysbiosis in goslings with gout as a result of interactions among the multitude of bacteria present in the gut, and the proliferation of a specific pathogenic genus, Proteobacteria, played a decisive role in this process. Moreover, the permeability increased not only in the intestinal epithelium but also in the renal endothelium, providing possibilities for gut-derived LPS to enter the blood circulation and damage the kidneys. The systemic LPS concentration was increased in the gout group and exhibited a positive correlation with the degree of renal injury. In addition, we also found that inflammatory disorders concurrently existed in the gut and kidney of goslings with gout, and the LPS/TLR4/MyD88 (Myeloid differentiation primary response gene 88) inflammatory signaling was activated. These results indicate that the loss of intestinal barrier as a result of gut dysbiosis causes the translocation of gut-derived LPS, which can play an important role in the development of gout in goslings through interference with kidney functions.
