益生菌对免疫的调节作用及对肠-肺轴的影响.

Probiotics play an important role in improving the health level of livestock and poultry, improving production performance, and antibiotic-free green farming. Probiotics can participate in immune regulation by regulating cell signaling factors and immune signaling pathways, thereby improving the physiological functions of the mucosal immune system to affect the health of the host. The intestinal microbiota is closely related to the mucosal immune system, and the intestine and lungs achieve two-way regulation through the interaction of microflora and immune regulation, which is called the gut-lung axis. Probiotics have considerable potential in the prevention and treatment of gastrointestinal and respiratory diseases, so it is necessary to have an in-depth understanding of the interaction mechanism between probiotics and intestinal microbiota and mucosal immunomodulation, so as to facilitate their application in animals production. In this paper, the relationship between probiotics and intestinal microflora and immune regulation in animals and the effect of probiotics on the gut-lung axis are discussed, in order to provide reference for the in-depth research and wide application of probiotics.
