PG - 56-67 AB - Dendritic cells (DCs) are a critical aspect of innate immune responses in addition to initiating adaptive immunity. In vitro generation of monocyte derived dendritic cells (MoDC) by culturing cells in IL-4 and granulocyte/macrophage colony stimulating factor (GM-CSF) has been reported for multiple species including swine. However, IL-4 is not a prominent cytokine detected in the periphery of common breeds of swine such as Yorkshire pigs. In this study, we report the generation and characterization of porcine MoDC in vitro using porcine IL-13 and porcine GM-CSF. These cells have the predicted expression of Class II MHC and T cell costimulatory molecules, phagocytic capacity and the ability to process and present antigen. Critically, porcine IL-13/GM-CSF MoDC have the unique ability to stimulate a primary mixed lymphocyte response in vitro. The type I interferon response of these MoDC to poly I:C (TLR3 ligand), LPS (TLR4 ligand) and CpG (TLR9 ligand) was tested. Of these TLR agonists, LPS or CpG did not stimulate induction of type I interferons, but a strong response was observed to poly I:C. This analysis shows that the generation of MoDCs in IL-13 yields cells of equivalent phenotype and function as IL-4 generated DC. However, for swine, in vitro generation of MoDC in IL-13 is likely to induce a more physiological cell population to study given expression of IL-4 is lacking in the periphery of these animals.
