Yolkin Isolated from Hen Egg Yolk as a Natural Immunoregulator, Activating Innate Immune Response in BMDM Macrophages

Figure 4

Upregulation of iNOS expression in BMDM cells after yolkin treatment. BMDM cells were treated with yolkin (10, 100, and 150 μg/ml) or LPS (1 μg/ml) or left untreated for 24 h. The level of iNOS protein was detected in cell lysates by immunoblotting using monoclonal anti-iNOS antibodies (a). Fold change in iNOS levels compared to β-actin (b). Results represent 3-4 independent experiments, and data are presented as . vs. control.
