Proteomic profiling of extracellular vesicles of the Lactiplantibacillus plantarum strains

Project description:The study was conducted on a model of Lactiplantibacillus plantarum, one of the most studied species widely used in the food industry as a probiotic microorganism and/or microbial starter culture. As a result of step-by-step selection from the L. plantarum 8p-a3 strain isolated from the «Lactobacterin» probiotic, the L. plantarum 8p-a3-Clr-Amx strain was obtained, showing increased resistance, compared with the parent strain, to amoxicillin-clavulanic acid (MIC 20 mcg/ml) and clarithromycin (MIC 10 mcg/ml). The L. plantarum strain DMC-S1 was isolated from the intestine of Drosophila melanogaster Canton-S line. Extracellular vesicles of this bacterium can play a significant role in the drug-resistance development and host-microbe interactions.

The commensal bacterium Lactiplantibacillus plantarum imprints innate memory-like responses in mononuclear phagocytes

Project description:Gut microbiota is a constant source of antigens and stimuli to which the resident immune system has developed tolerance. However, the mechanisms by which mononuclear phagocytes, specifically monocytes/macrophages, cope with these usually pro-inflammatory signals is poorly understood. Here, we show that innate immune memory promotes anti-inflammatory homeostasis using as a model strains of the commensal bacterium, Lactiplantibacillus plantarum. Priming of monocytes/macrophages with bacteria, especially in its live form, enhances bacterial intracellular survival and decreases the release of pro-inflammatory signals to the environment, with lower production of TNF and higher levels of IL-10. Analysis of the transcriptomic landscape of these cells shows downregulation of pathways associated with the production of reactive oxygen species (ROS) and the release of cytokines, chemokines and antimicrobial peptides. Indeed, the induction of ROS prevents memory-induced bacterial survival. In addition, there is a dysregulation in gene expression of several metabolic pathways leading to decreased glycolytic and respiratory rates in memory cells. These data support commensal microbe-specific metabolic changes in innate immune memory cells that might contribute to homeostasis in the gut.

Food-associated Lactiplantibacillus plantarum C9O4 reverts inflammation and apoptosis in intestinal epithelial cells: a proteomic insight

Project description:Nowadays, Western diets and lifestyle lead to an increasing occurrence of chronic gut inflammation, that represents an emerging health concern with still a lack of successful therapies. Fermented foods, and their associated Lactic Acid Bacteria, have recently regained popularity for their probiotic potential including the maintenance of gut homeostasis by modulating the immune and inflammatory response. Our study aims to investigate the cross-talk between the food-borne strain Lactiplantibacillus plantarum C9O4 and intestinal epithelial cells in an in vitro inflammation model. Cytokines profile shows the ability of C9O4 to significantly reduce levels of IL-2, IL-5, IL-6, and IFN-γ. Proteomic functional analysis reveals an active host-microbe interaction that highlights an immunoregulatory role of C9O4, able to revert both the detrimental effects of IFN-γ through the JAK/STAT pathway and the apoptosis process in inflamed cells. These results suggest a promising therapeutic role of fermented food-associated microbes for the management of gastrointestinal inflammatory diseases.
