Fungal β-Glucans: Biological Properties, Immunomodulatory Effects, Diagnostic and Therapeutic Applications.

Abstract

Research from the past to the present has shown that natural ingredients in the human daily diet play a crucial role in preventing various diseases. One well-known compound is β-glucan, a natural polysaccharide found in the cell walls of many fungi, yeasts, and some microorganisms, as well as in plants such as barley and wheat. β-glucans are widely recognized for their ability to lower cholesterol and blood glucose levels, thereby reducing the risk of cardiovascular disease and diabetes. In addition to their effects on lipid levels and glucose metabolism, these molecules exhibit antioxidant properties by eliminating reactive oxygen species. As a result, they help lower the risk of conditions such as atherosclerosis, cardiovascular disease, neurological disorders, diabetes, and cancer. Furthermore, β-glucans have been reported to possess immune-boosting and antitumor effects. By binding to specific receptors on the surface of immune cells, they stimulate immune activity. Additionally, β-glucans belong to a group of probiotics that promote the growth and activity of beneficial gut microbiota, preventing the proliferation of harmful pathogens. They play a vital role in maintaining gastrointestinal health, reducing inflammation, and lowering the risk of colon cancer. Further research on the health benefits of β-glucans may be key to improving overall well-being and preventing many chronic non-communicable diseases such as diabetes, high cholesterol, obesity, cardiovascular disease, and cancer.
