Abstract Title:
[Vitamin C and its physiological role with respect to the components of the immune system].
Abstract:
Vitamin C is a water soluble micronutrient commonly found in our diet which orchestrates the function of both innate and adaptive immune system, influencing both cellular and humoral immune responses. Vitamin C inhibits excessive activation of the immune system to prevent tissue damage, but also supports antibacterial activity, stimulates NK cells and differentiation of Th0 subset into Th1 characterized by interferonγ production. In addition, vitamin C interferes with the synthesis of proinflammatory cytokines, or with the expression of adhesive molecules. Moreover, vitamin C as an antioxidat protects the immune cells against intracellular ROS (reactive oxygen species) formed in the inflammatory response. Vitamin C as an enzymatic cofactor is extremely important in maintaining tissue integrity, and plays a crucial role in formation of skin, epithelial and endothelial barriers.
