Autoimmunity

β-glucans are potent but not interchangeable: depending on structure, dose, and route, they can tilt Dectin-1/PRR signaling toward tolerance (Treg-supporting, gut-anchored) or inflammation (Th17/Th1), yielding benefit in some autoimmune models and harm in others; hence the promise and the caution for disease- and product-specific trials.
