Fungal Recognition Enhances Mannose Receptor Shedding through Dectin-1 Engagement

Dectin-1 deficiency and mucocutaneous fungal infections.

In addition, an independent data and safety monitoring committee regularly reviewed the trial. Some participants would not even have met the criteria for gestational diabetes (more evidence of clinical equipoise). We strongl...

Dectin-2 is a Syk-coupled pattern recognition receptor crucial for Th17 responses to fungal infection

Innate immune cells detect pathogens via pattern recognition receptors (PRRs), which signal for initiation of immune responses to infection. Studies with Dectin-1, a PRR for fungi, have defined a novel innate signaling pathway involving Syk kinase and the adaptor CARD9, which is critical for inducing Th17 responses to fungal infection. We show that another C-type lectin, Dectin-2, also signals ...

The fungal pattern recognition receptor, Dectin-1, and the associated cluster of C-type lectin-like receptors

The mammalian natural killer gene complex (NKC) contains several families of type II transmembrane C-type lectin-like receptors (CLRs) that are best known for their involvement in the detection of virally infected or transformed cells, through the recognition of endogenous (or self) proteinacious ligands. However, certain CLR families within the NKC, particularly those expressed by myeloid cell...

Fungal recognition is mediated by the association of dectin-1 and galectin-3 in macrophages.

Dectin-1, the major β-glucan receptor in leukocytes, triggers an effective immune response upon fungal recognition. Here we use sortase-mediated transpeptidation, a technique that allows placement of a variety of probes on a polypeptide backbone, to monitor the behavior of labeled functional dectin-1 in live cells with and without fungal challenge. Installation of probes on dectin-1 by sortaggi...
