 Glucons are complex carbohydrates found in the cell walls of fungi, bacteria and plants. They are composed of long chains of 1-3-linked D-glucose molecules, and they can stimulate both humeral and cellular immunity in humans and animals. Additionally, glucons have been linked to toxicological effects such as sick-building syndrome and respiratory irritation. Research has shown that these effects may be due to the particular form of glucons, which can cause inflammation when inhaled. This inflammatory response is thought to be treated by the glucons interaction with macrophages and other immune cells, which leads to increased cytokine production.
