Non-classical monocytes contribute to innate immune training in cattle.

ABSTRACT: Innate immune training is defined as a property of innate immune cells to react stronger to a secondary contact with pathogens. Induction of innate immune training has been reported for a variety of pathogens and selected pattern recognition receptor-ligands, such as β-glucans (βG). We examined whether Saccharomyces cerevisiae cell wall component βG induces training in bovine monocytes in vitro based on a heightened TNF secretion after stimulation by trained monocyte-derived macrophages with Escherichia coli LPS. Sorted CD14-expressing monocytes (classical and intermediate monocytes), as well as single populations of sorted classical, intermediate and non-classical monocytes could not be trained by βG, whereas macrophages derived from plastic-adherent mononuclear cell
