Abstract
Background
Many natural products have immunomodulatory properties. However, the mechanism of immunomodulatory activities are poorly understood.
Objectives
This study evaluated the influence of bovine colostrum products, a whey product, or their combinations with other natural products on human peripheral blood mononuclear cells' (PBMC) ability to produce cytokines upon activation.
Methods
PBMCs were pretreated with ultrafiltered colostrum, nano-filtered bovine colostrum, egg yolk extract, a botanical blend, colostrum + egg yolk extract, colostrum + egg yolk + botanical blend, and fermented whey and then stimulated with lipopolysaccharide or phytohemagglutinin. Cytokine production was measured by the Luminex assay.
Results
All study products demonstrated immunomodulatory properties by regulating cytokines production by activated PBMCs. Ultrafiltered colostrum alone displayed the highest immune stimulatory activity. It stimulated proinflammatory cytokine production by lipopolysaccharide-activated PBMCs and suppressed cytokine production by phytohemagglutinin-activated cells. Other study products mainly suppressed cytokine release by both cell types. The immunomodulatory properties depended upon the dose of the products used in the study.
Conclusions
All tested products modulated innate and adaptive immune cell activities. Most of the products demonstrated anti-inflammatory properties, except ultrafiltered colostrum, which stimulated the lipopolysaccharide-activated PBMC production of inflammatory cytokines. These products can be potentially used to support overall immune health.
