PG - 573-578 LID - 10.1093/mmy/myw105 [doi] AB - Aspergillus fumigatus is an opportunistic fungal pathogen causing detrimental infections in immunocompromised individuals. Dendritic cells (DCs) are potent antigen-presenting cells and recognize the A. fumigatus cell wall component beta-1,3 glucan via Dectin-1, followed by DC maturation and cytokine release. Here, we demonstrate that human primary myeloid DCs (mDCs) interact with different morphotypes of A. fumigatus. Dectin-1 is expressed on mDCs and is down-regulated after contact with A. fumigatus, indicating that mDCs recognize A. fumigatus via this receptor. Blocking of Dectin-1, followed by stimulation with depleted zymosan diminished the up-regulation of the T-cell co-stimulatory molecules CD40, CD80, HLA-DR and CCR7 on mDCs and led to decreased release of the cytokines TNF-alpha, IL-8, IL-1beta and IL-10.
