IL-4
Interleukin-4 (IL-4) is a critical Th2 cytokine that regulates immune responses by promoting differentiation of naive CD4+ T cells into Th2 cells[1]. Mechanistically, IL-4 activates the JAK-STAT6 signaling pathway, leading to transcriptional induction of genes involved in humoral immunity, including IgE class switching in B cells[1]. In disease models, IL-4 contributes to the pathogenesis of allergic inflammation and asthma by inducing eosinophilia, mucus hyperproduction, and alternatively activated macrophages[1]. Compared with related isoforms such as IL-13, IL-4 exhibits unique receptor engagement, preferentially signaling through IL-4Rα paired with the common gamma chain, which defines distinct cellular responses[1]. IL-4 agonists and inhibitors have been applied in experimental research to modulate Th2-skewed immune responses, enabling the study of allergic airway inflammation and potential therapeutic interventions[1]. Experimental blockade of IL-4 reduces IgE production and airway hyperreactivity, confirming its central role in type 2 immunity and providing a framework for targeted immunomodulation in preclinical models[1]. Therefore, IL-4 serves as both a mechanistic marker and a modifiable factor in studies of cytokine-driven inflammation.

Platycodin D2
0 ImagesPlatycodin D2 is an orally active triterpenoid saponin found in Platycodon grandiflorum.

Arabinoxylan (Medium viscosity)
0 ImagesArabinoxylan 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.
