TLR2 Activator

Zymosan (ZM), 95% is a yeast cell wall-derived carbohydrate-rich preparation and immunomodulator. Zymosan (ZM), 95% binds to and activates TLR-2, TLR-4, and Dectin-1 receptor to trigger downstream signaling pathways. Zymosan (ZM), 95% upregulates TLR-2, TLR-4, and TNF-α mRNA expression, increases serum TNF-α levels, and stimulates splenocyte number and viability in mice. Zymosan (ZM), 95% attenuates melanoma growth progression, modulates macrophage marker gene expression, and mediates phagocytosis, ROS generation, and cytokine production. Zymosan (ZM), 95% reduces Connexin 43 protein and mRNA levels, inhibits gap junctional intercellular communication, and induces proinflammatory factor production in human corneal cells. Zymosan (ZM), 95% induces peritoneal inflammation in mice, functions as a drug carrier, and supports fibroblast cell attachment in hydrogel formulations. Zymosan (ZM), 95% can be used for the research of melanoma, tumors, fungal keratitis, ocular surface inflammatory disorders, and peritoneal inflammation.

Macrophage-activating lipopeptide 2 (MALP-2) is an agonist of Toll like receptors TLR-2/TLR-6. Macrophage-activating lipopeptide-2 can enhance endothelial nitric oxide synthase (eNOS) phosphorylation and endothelial cell release of NO, thereby improving vasodilation. Macrophage-activating lipopeptide-2 can enhance endothelial adhesion of white blood cells and improve perfusion recovery and collateral growth in the hind limbs of hypercholesterolemic Apoe deficient mice undergoing experimental femoral artery ligation (FAL).

Lard oil is an orally active biochemical reagent. Lard oil upregulates PERK, eIF2a, CHOP, OPN, TLR2, TLR4, TNF-α, and downregulates GRP78 and IRE1a. Lard oil induces responses such as body fat accumulation, elevated serum insulin levels, increased HOMA-IR, hepatic ectopic lipid deposition, hepatic endoplasmic reticulum stress, and hepatic inflammation. Lard oil can be used in studies related to diet-induced obesity, insulin resistance, and non-alcoholic fatty liver disease.

Creatine ethyl ester (CEE) is a readily available form of creatine used in supplements. Creatine ethyl ester (CEE) upregulates TLRs (TLR2, 3, 4 and TLR7) over the short-term.
