Cloudy Apple Juice Fermented by Lactobacillus Prevents Obesity via Modulating Gut Microbiota and Protecting Intestinal Tract Health.

ABSTRACT: Obesity and hyperglycemia are two serious chronic diseases that are increasing in incidence worldwide. This research aimed to develop a fermented cloudy apple juice with good hyperglycemia intervention activities. Here, cloudy apple juice (CAJ), cloudy apple juice rich in polyphenols (CAJP) and fermented cloudy apple juice rich in polyphenols (FCAJP) were prepared sequentially, and then the effects of the three apple juices on weight, lipid level, gut microbiota composition and intestinal tract health were evaluated for obese mice induced by a high-fat diet. The research findings revealed that the FCAJP showed potential to inhibit the weight gain of mice, reduce fat accumulation, and regulate the blood lipid levels of obese mice by decreasing the ratio of the Firmicutes/Bacteroidotas, improving the Sobs, Ace, and Chao indexes of the gut microbiota and protecting intestinal tract health. In addition, the FCAJP augmented the abundance of Akkermansia and Bacteroides, which were positively related to SCFAs in cecal contents. This study inferred that FCAJP could be developed as a healthy food for preventing obesity and hyperglycemia.

Project description:Reactive arthritis is the development of sterile joint inflammation as a sequel to a remote infection, often in the gut. We have previously shown that a low dose of S. enteritidis inoculated to streptomycin-pretreated mice generates a self-limiting enterocolitis suitable for studying reactive arthritis. Here we show that consumption of Lactobacillus casei prior to infection abolishes intestinal and joint inflammation triggered by Salmonella. BALB/c mice were sacrificed after infection; intestinal and joint samples were analyzed for histological changes and expression of cytokines. TNF-α was measured by ELISA and the expression of IL-1β, IL-6, IL-10, IL-17, IL-23 and TGF-β was assessed by qPCR. L. casei consumption prevented Salmonella-induced synovitis, the increment of TNF-α in knees and the increase of IL-17 expression in popliteal and inguinal lymph nodes. At intestinal level consumption of L. casei drastically diminished S. enteritidis invasiveness and shortened splenic persistence of the pathogen. Bacterial loads recovered at days 2 and 5 from Peyer's patches were 10-fold lower in mice fed with L. casei. In accordance, we found that the augment in gut permeability induced during enterocolitis was decreased in those animals. Consumption of L. casei prior to infection failed to increase anti- inflammatory molecules such as IL-10 and TGF-β in the intestine. On the other hand, consumption of L. casei abrogated the expression of TNF-α, IL-17, IL-23, IL-1β and IL-6 in cecum and mesenteric lymph nodes. These cytokines are needed for differentiation of immune cells involved in the development of reactive arthritis such as Th17 and γδ T cells. Trafficking of these inflammatory cells from the gut to the joints has been proposed as a mechanism of generation of reactive arthritis. Our results suggest that L. casei consumption prevents Salmonella-induced synovitis by altering the intestinal milieu necessary for differentiation of cells involved in the generation of joint inflammation.
