Project description:Infectious enteritis is often accompanied with immuno-disorder of intestinal immune cells caused by microbials infection. Trained immunity is classically characterized by long-term functional reprogramming of innate immune cells to combat infectious diseases. However, whether the induction of trained immunity plays a role in protecting infectious enteritis remains largely unknown. Here, through establishing an in vivo β-glucan training and E. piscicida infection model in zebrafish, we observe that induction of trained immunity could alleviate bacterial infection-caused enteritis. Moreover, we identify intestinal complement C3 as a crucial target of trained immunity and could be amplified in response to bacterial infection. Furthermore, we reveal that trained immunity could reverse the reduction of intestinal Th17 cells in C3-dependent manner to alleviate infectious enteritis. Taken together, our results uncover the role of complement C3-mediated trained immunity in maintaining Th17 cells and intestine homeostasis, and provide a theoretical strategy for immunotherapies of infectious enteritis.

Project description:This study was conducted to evaluate the effects of dietary supplemental magnolol and honokiol in broilers infected with S. pullorum. A total of 360 one-day-old broilers were selected and randomly divided into four groups with six replicates: the negative control group (CTL), S. pullorum-infected group (SP), and the S. pullorum-infected group supplemented with 300 mg/kg honokiol (SPH) or magnolol (SPM). Chicks in the SP, SPH, and SPM groups were orally treated with a 0.5 ml (4×108 CFU/mL) S. pullorum solution at 5 days of age, while chicks in the control (CTL) group received the same amount of sterilized PBS at the same age.At 14 and 21 days of age, one chick from each replicate was randomly selected to be weighed and slaughtered by jugular exsanguination after a 12-h fasting period. The ileum samples were collected to analyze the differential expression genes.
Project description:The goal of this study was to understand the link between maternal oral dysbiosis and the gut health of offspring. We demonstrate that maternal oral dysbiosis can have lasting health impacts on offspring. Ligature-induced periodontitis in mothers promotes the expansion of oral pathobionts in the mouth, which are transmitted to the infant gut, rendering offspring more susceptible to enteritis. Notably, although these maternal oral pathobionts are eradicated as the microbiota matures, the imprinted susceptibility to enteritis persists into adulthood.
Project description:We established a bacteria infective intestinal inflammation in turbot (Scophthalmus maximus). And found that β-glucan could significantly alleviate the phenotype of turbot intestinal inflammation. We performed single cell transcriptome analysis to study bacteria infective intestinal inflammation and the effects of β-glucan. Furthermore, we revealed that β-glucan through activates Th17 cells to alleviate intestinal inflammation in turbot.
