In vitro and in vivo downregulation of C3 by lipoteichoic acid isolated from Lactobacillus plantarum K8 suppressed cytokine-mediated complement system activation.

Complement component 3 (C3) is one of the proteins associated with complement cascades. C3 plays an essential role in three different pathways-the alternative, classical and lectin pathways. It is well known that cytokines activate complement system and increase complement component C3 production.

Differential Cytokine Regulatory Effect of Three Lactobacillus Strains Isolated from Fermented Foods.

Lactic acid bacteria (LAB) isolated from fermented foods have potential as a treatment for immune-related disorders and the use of LAB has been increasing worldwide. In this study, the differential cytokine regulatory effect was examined with three isolates of lactobacilli strains; namely, Lactobacillus plantarum K55-5 isolated from dairy product, and L. sakei K101 and L.

Lipoteichoic Acid Isolated from Weissella cibaria Increases Cytokine Production in Human Monocyte-Like THP-1 Cells and Mouse Splenocytes.

Lactic acid bacteria (LAB) have beneficial effects on intestinal health and skin diseases. Lipoteichoic acid (LTA), a cell wall component of gram-positive bacteria, is known to induce the production of several cytokines such as TNF-α, IL-1β, and IL-8 and affect the intestinal microflora, anti-aging, sepsis, and cholesterol level. In this study, Weissella cibaria was isolated from Indian dairy products, and we examined its immune-enhancing effects.

Immune Regulatory Effect of Newly Isolated Lactobacillus delbrueckii from Indian Traditional Yogurt.

Lactic acid bacteria (LAB) are microorganisms that are believed to provide health benefits. Here, we isolated LAB from Indian fermented foods, such as traditional Yogurt and Dosa. LAB from Yogurt most significantly induced TNF-α and IL-1β production, whereas LAB from Dosa induced mild cytokine production.
