Development of a lactic acid bacteria strain that suppresses chronic inflammation and improves glucose and lipid metabolism

Chronic inflammation caused by aging, obesity, and lifestyle disturbances can lead to the production of inflammatory cytokines and insulin resistance, reducing glucose and lipid metabolism. Lactic acid bacteria (LAB) have various bioactivities, and certain types of LAB have been reported to exhibit...

description Chronic inflammation caused by aging, obesity, and lifestyle disturbances can lead to the production of inflammatory cytokines and insulin resistance, reducing glucose and lipid metabolism. Lactic acid bacteria (LAB) have various bioactivities, and certain types of LAB have been reported to exhibit anti-inflammatory effects. We hypothesized that LAB strains, which can strongly induce the production of anti-inflammatory cytokines by immune cells in the intestinal tract, may improve glucose and lipid metabolism by suppressing chronic inflammation. We selected Lactiplantibacillus plantarum OLL2712 (OLL2712) from the LAB library owned by Meiji Co., Ltd. based on its ability to induce the production of interleukin-10 (IL-10), optimized the culture conditions of OLL2712 for industrial applications, and verified the efficacy of the strain in animal and clinical studies. The results showed that OLL2712 bacterial cells in the exponential phase had notably higher anti-inflammatory properties than the cells in the stationary phase and led to the inhibition of chronic inflammation and improvement of glucose and lipid metabolism in animal studies. Two randomized controlled trials consisting of healthy adults with elevated blood glucose levels or body mass indices (BMIs) also showed that the intake of OLL2712 suppressed the aggravation of chronic inflammation and improved glucose and lipid metabolism. This review identified a novel LAB strain that may contribute to diabetes and obesity prevention and demonstrated its clinical efficacy. In addition, the mechanism of action of this LAB strain through the intestinal immune system was partially elucidated, and the importance of optimizing the culture conditions of LAB was clarified.
