Dectin-1 and Dectin-2 in innate immunity against fungi.
Dectin-1 and Dectin-2 are type II transmembrane proteins of the C-type lectin family with single carbohydrate recognition domains (CRDs) in their extracellular region. They are expressed mainly in dendritic cells and macrophages. Dectin-1 recognizes β-glucans with its CRD and transduces signals through its immunoreceptor tyrosine-based activation motif (ITAM)-like motif in the cytoplasmic domai...
متن کاملRecognition of non-self-polysaccharides by C-type lectin receptors dectin-1 and dectin-2.
The discovery of several transmembrane receptors expressed by antigen presenting cells, including those that detect and interact with specific sugar moieties on the surface of microbes, has improved our understanding of how immunity against infection is generated. This knowledge, in turn, prompted us to review such interactions with emphasis on C-type lectin receptors and a focus on the roles o...
متن کاملArabinoxylan activates Dectin-1 and modulates particulate β-glucan-induced Dectin-1 activation.
SCOPE Arabinoxylan is one of the most commonly consumed dietary fiber. Immunomodulation by arabinoxylan is documented but the mechanisms by which these immune-effects are accomplished are unknown. METHODS AND RESULTS By applying reporter cell lines for Toll-like receptors (TLRs) and Dectin-1, we demonstrated that arabinoxylan interacts with Dectin-1 receptors and not with TLRs. Arabinoxylan a...
متن کاملDectin-1 mediates macrophage recognition of Candida albicans yeast but not filaments.
The ability of Candida albicans to rapidly and reversibly switch between yeast and filamentous morphologies is crucial to pathogenicity, and it is thought that the filamentous morphology provides some advantage during interaction with the mammalian immune system. Dectin-1 is a receptor that binds beta-glucans and is important for macrophage phagocytosis of fungi. The receptor also collaborates ...
متن کاملCo-stimulation of TLR4 and Dectin-1 Induces the Production of Inflammatory Cytokines but not TGF-β for Th17 Cell Differentiation
Collaboration of TLR and non-TLR pathways in innate immune cells, which acts in concert for the induction of inflammatory cytokines, can mount a specific adaptive immune response tailored to a pathogen. Here, we show that murine DC produced increased IL-23 and IL-6 when they were treated with LPS together with curdlan that activates TLR4 and dectin-1, respectively. We also found that the induct...
