Convergence of plant sterols and host eukaryotic cell-derived defensive lipids at the infectious pathogen-host interface.

Plant sterols (PSs) exhibit intrinsic functions such as antibacterial effects. Their effects simultaneously on both host-mediated and bacteria-mediated pathogenesis are not yet fully understood. We hypothesized that when absorptive cells, defensive cells and detoxer cells are cultured together, their convergent response to an infectious pathogen depends on the molecular mimicry between the ingested sterols and their own defensive lipids.

Exploring the Interplay between Nutrients, Bacteriophages, and Bacterial Lipases in Host- and Bacteria-mediated Pathogenesis.

Background And Aims: Pathogenic bacteria and host cells counteract or neutralize each other's effect in two fundamental ways: Direct invasion and secretion of various substances. Among these, lipases secreted by pathogenic bacteria and host cell lysozyme are key actors. Secreted lipases from pathogenic bacterial are suggested as a key player in the pathogen-host interaction.

Endogenous Ethanol-producing Bacteria Interference in Pathogen-host Crosstalk.

Background And Aims: The host micronutrient milieu is a compilation of factors of both endogenous and exogenous origin. This milieu shapes the host's immune responses and can control the inflammatory response of the host when infected. Among vitamins, B12 plays a key role in the defense process because there is intense competition for it between pathogenic invaders and infected host cells.

Oral Mucosal Cell Culture Model to Study the Effect of Phage on the Interplay between Food Components and Oral Microbiota.

Background And Aims: Dietary habits, food, and nutrition-associated oral dysbiosis lead to the formation of microbial biofilm, which affects the overall health of an individual by promoting systemic diseases like cardiovascular disease, immunological disorders, and diabetes. Today's diets contain a variety of fermentable carbohydrates, including highly processed starch and novel synthetic carbohydrates such as oligofructose, sucralose, and glucose polymers. These constitute risk factors in the initiation and progression of oral dysbiosis.
