Yeast beta-glucan is recognized by the immune system as a pathogen-associated molecular pattern (PAMP) that activates immune cells through specific receptors. The main receptor for yeast beta-glucan is Dectin-1, which is expressed on the surface of various immune cells, including macrophages, dendritic cells, and neutrophils.
Upon binding to yeast beta-glucan, Dectin-1 undergoes a conformational change that triggers a signaling cascade leading to the activation of the immune cell. This includes the recruitment of other receptors and adaptor molecules such as Syk, CARD9, and NF-κB, which ultimately results in the activation of transcription factors and the production of cytokines and chemokines.
Activation of the immune system by yeast beta-glucan can lead to several downstream effects, including the enhancement of phagocytosis, the production of reactive oxygen species (ROS), and the priming of the adaptive immune response. These effects can help to eliminate the invading pathogen and promote the resolution of the infection.
Overall, the activation mechanism of the yeast beta-glucan immune system involves the recognition of the PAMP by the Dectin-1 receptor, which triggers a complex signaling cascade leading to immune cell activation and the production of cytokines and chemokines.
Yeast beta glucan is a type of soluble fiber that has been shown to have cholesterol-lowering effects. The mechanism by which yeast beta glucan lowers cholesterol is through its ability to bind to bile acids in the intestine, leading to their excretion from the body.
Bile acids are made from cholesterol in the liver and are released into the small intestine to aid in the digestion and absorption of dietary fats. Once they have served their function, the bile acids are normally reabsorbed in the small intestine and recycled back to the liver for reuse. However, when yeast beta glucan is present in the intestine, it binds to the bile acids and prevents their reabsorption.
As a result, the liver needs to produce more bile acids from cholesterol to replace the lost bile acids, which lowers the amount of cholesterol in the liver. This, in turn, leads to an increase in the uptake of LDL cholesterol from the bloodstream to the liver to produce more bile acids, resulting in lower levels of LDL cholesterol in the blood.
Additionally, yeast beta glucan has been shown to stimulate the production of short-chain fatty acids in the colon. These fatty acids may also contribute to the cholesterol-lowering effects of yeast beta glucan.
