Nicotine- and tar-removed cigarette smoke extract modulates the antigen presentation function of mouse bone marrow-derived dendritic cells
Dendritic cells (DCs) take up antigens derived from pathogens such as bacteria and viruses, and from tumor cells and induce the activation of antigen-specific T cells through major histocompatibility complex (MHC)-mediated antigen presentation. Mainstream cigarette smoke extract (CSE) has various effects, and the effects of its major components, nicotine and tar, have been analyzed extensively. Recently, the physiological effects of nicotine- and tar-removed CSE (cCSE) have also been reported. However, the effects of cCSE on DC-mediated immune responses remain unknown. In this study, we found that cCSE enhanced lipopolysaccharide (LPS)-stimulated induction of the expression of MHC-I and MHC-II on the cell surface of mouse bone marrow-derived DCs (BMDCs). In contrast, cCSE suppressed the induction of CD86 induced by stimulation with curdlan and interferon-γ (IFN-γ). In addition, cCSE suppressed the production of IL-12, IL-23, and IL-10 by LPS and curdlan stimulation. In the presence of cCSE, LPS-stimulated BMDCs showed enhanced activation of CD4 and CD8 T cells and increased IL-2 production from T cells by antigen presentation in a mixed-leukocyte reaction assay. In contrast, cCSE did not affect the activation of T cells by curdlan- or IFN-γ-stimulated BMDCs, and curdlan-stimulated BMDCs suppressed IL-17 production from T cells and enhanced IFN-γ production. These results suggest that cCSE has different effects on the activation signals induced by LPS, curdlan, and IFN-γ in BMDCs and modulates the antigen presentation function of BMDCs.
