Neolactoferrin As a Stimulator of Innate and Adaptive Immunity

The effect of the innovative product Neolactoferrin, a natural combination of recombinant human lactoferrin (90%) and goat lactoferrin (10%) isolated from the milk of transgenic goats carrying the full-length human lactoferrin gene, on human immune system cells was studied. Neolactoferrin enhanced the production of IL-1β. Neolactoferrin saturated with iron ions increased the synthesis of pro-inflammatory cytokine TNFα. It determined the direction of the differentiation of precursor dendrite cells. Under the action of T cells, Neolactoferrin amplified the expression of the transcription factors responsible for the differentiation of Th- and Treg-cells and stimulated the production of both IFNγ and IL-4. The results suggest that Neolactoferrin exhibits an immunotropic activity and hinders the development of immune inflammatory processes. Iron saturation of Neolactoferrin increases its pro-inflammatory activity.
