iE-DAP
iE-DAP is a Nod1 agonist. iE-DAP activates NOD1, which in turn activates the NF-κB signaling pathway and MLCK signaling pathway, inducing cellular inflammatory responses and tight junction disruption. iE-DAP downregulates the expression of ZO-1 and Occludin genes. iE-DAP increases the secretion of IL-6, GRO-α, MCP-1, IL-8 and MIP-1β in term human trophoblast cell cultures. iE-DAP triggers preterm birth in pregnant mice, reduces fetal body weight, and induces fetal inflammation. iE-DAP is applicable to research related to mastitis and preterm birth.

Biological Activity
iE-DAP (10-10000 ng/mL; 1-24 h) upregulates the mRNA expression of IL-1β, IL-6 and IL-8 in BMECs, downregulates the mRNA expression of ZO-1 and Occludin in BMECs, reduces TEER, and increases the paracellular dextran permeability in BMECs[1].
iE-DAP (1000 ng/mL; 12 h) upregulates the protein expression levels of p-MLC2 and MLCK as well as the phosphorylation level of MLC2, downregulates the mRNA and protein expression levels of ZO-1 and Occludin, reduces TEER, increases the paracellular dextran permeability, and disrupts the distribution of ZO-1 in BMECs[1].
iE-DAP (1000 ng/mL; 12 h) upregulates the mRNA expression and secretion levels of IL-1β, IL-6 and IL-8 in BMECs, and activates the NF-κB pathway by increasing the expression of p-p65 protein, the phosphorylation level of p65 and the nuclear translocation of p65[1].
iE-DAP (1000 ng/mL; 12 h) upregulates the expression of NOD1 protein, p-p65 protein, the phosphorylation level of p65, and promotes the nuclear translocation of p65 in BMECs, thereby activating the NOD1/NF-κB pathway[1].
iE-DAP (100 μg/mL; 72 h) potently stimulates human primary third-trimester cytotrophoblasts to secrete IL-6, GRO-α, MCP-1, IL-8 and MIP-1β[2].
