PG - 205-10 LID - S0165-2427(13)00196-7 [pii] LID - 10.1016/j.vetimm.2013.06.014 [doi] AB - Dendritic cells (DCs) are crucial for initiation of both innate and adaptive immune responses. TLR ligands combine with Toll-like receptors (TLRs) expressed on the DC surface and induce DC maturation. The potential effect of three types of TLR ligands (Bacillus subtilis (B. subtilis) spores, polyinosinic-polycytidylic acid and CpG oligodeoxynucleotides) on chicken bone marrow-derived DCs (chBM-DCs) maturation was studied. The chBM-DCs cultured in presence of recombinant chicken granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin (IL)-4 displayed the typical morphology of DCs after 7 days of culture. These immature chBM-DCs up-regulated the expression of MHC-II and of the putative CD11c, but had yet low to moderate levels of the CD40 and CD86 co-stimulatory molecules. After stimulation by the TLR ligands, the chBM-DCs displayed a more mature morphologic phenotype, significantly increased the CD40 and CD86 cell surface expression levels and gained the ability to stimulate proliferation of naive T cells in the allogeneic mixed lymphocyte reaction, compared to the immature chBM-DCs. In conclusion, our data demonstrated that all three TLR ligands were strong stimuli for driving chBM-DCs maturation in vitro, with B. subtilis spores being the most efficient.
