Arabinoxylan Medium viscosity is an orally active Dectin-1 splice variant modulator, glucose absorption inhibitor, and chyme viscosity enhancer. Arabinoxylan Medium viscosity inhibits particulate β-glucan-induced Dectin-1A activation and mildly suppresses Dectin-1B activation. In human dendritic cells stimulated with particulate β-glucan, Arabinoxylan Medium viscosity reduces the production of IL-10 and TNF-α, and increases the production of IL-4 and IL-23. Arabinoxylan Medium viscosity also supports antifungal immune responses without activating TLR2, TLR4 or TLR5, and does not induce cytokine production when used to stimulate human dendritic cells alone. Arabinoxylan Medium viscosity increases small intestinal chyme viscosity, gets degraded in the large intestine to produce short-chain fatty acids, reduces glucose absorption and insulin response, and improves glucose homeostasis. Arabinoxylan Medium viscosity supports microbial fermentation and the growth of beneficial microbiota in the gastrointestinal tract, prevents bile acid reabsorption, and delays starch digestion. Arabinoxylan Medium viscosity can be used in research related to type 2 diabetes, impaired glucose tolerance, and metabolic syndrome .

Human TLR4 mRNA encodes the human toll like receptor 4 (TLR4) protein, a member of the Toll-like receptor (TLR) family which plays a fundamental role in pathogen recognition and activation of innate immunity. TLR4 has been implicated in signal transduction events induced by lipopolysaccharide (LPS) found in most gram-negative bacteria.
