Episode notes
Structure Dictates Beta-Glucan Function
- Beta-glucans are polysaccharides from cell walls of yeast, fungi, cereals, bacteria and algae that affect immunity.
- Their source and molecular structure determine bioavailability and the immune effects they produce.
3D Branching Unlocks Immune Activation
- Yeast beta-1,3/1,6 glucans have long 1,6 branches that form a 3D structure critical for immune activation.
- Linear beta-glucans (e.g., some cereal types) lack the branching needed to stimulate immune cells effectively.
Beta-Glucans Work As Immune 'Warning Posters'
- Beta-glucans act as pathogen-associated molecular patterns (PAMPs) that warn and 'train' innate immune cells.
- Pattern recognition receptors (PRRs) like Dectin-1 bind beta-glucans and trigger faster, stronger immune responses.
