Lactoferrin (LF) is an iron-binding glycoprotein that is present in colostrum, milk, and other body secretions. The objective of this study was to investigate the effects of lactoferrin hydrolysates (LHs) on the production of immunomodulatory factors, including inflammatory related cytokines. The nuclear factor (NF)-κB reporter assay using human embryonic kidney 293 cells (HEK-293) revealed that NF-κB activity was significantly decreased by 1, 50, and 100 ㎍/mL of LH and the fractions above and below the 10 kDa LH. The mRNA expression of interferon (IFN)-γ in rat basophilic leukemia mast cells (RBL-2H3) treated with the fraction above the 10 kDa LH decreased in a dose-dependent manner, but the cells treated with LH and the fraction below the 10 kDa LH showed an increased expression of IFN-γ in a dose-dependent manner. The level of cyclooxygenase (COX)-2 expression decreased dosedependently in RBL-2H3 cells treated with LH and the fraction above the 10 kDa LH, but the cells treated with the fraction below the 10 kDa LH showed an increased COX-2 expression in a dose-dependent manner. The mRNA expression of interleukin (IL)-4) was dose-dependently decreased by the fraction below the 10 kDa LH in human mast cells (HMC-1). The mRNA expressions of tumor necrosis factor (TNF)-α and IL-6 were significantly dose-dependently decreased by the fractions above and below the 10 kDa LH, but was dose-dependently increased by LH. The production of IL-4 was a little increased by the fraction above the 10 kDa LH compared to the positive control, but was decreased with LH and the fraction below the 10 kDa LH in HMC-1 cells. It was concluded that LF hydrolysates had an immunomodulating effect on anti-, pro-inflammatory and anti-allergic reactions.
