The receptor protein Dectin-1 recognizes structures found on cancerous cells, and then triggers an anti-tumor immune response.

The mushroom cell wall contains polysaccharides that can activate cells of the innate immune system through receptors such as Toll-like (TLR) and dectin-1. In present study, Pleurotus eryngii polysaccharide fractions containing a 3-O methylated mannogalactan (1?3)/(1?6)-?-d-glucans were isolated extensively characterized by 2D NMR methylation analysis. Traces (1?3)-?-d-glucan (1?2)-?-d-mannan a...

Recurrent Vulvovaginal infections (RVVI) are the commonly reported microbiological syndrome affecting millions of women globally. Various molecules of innate immune system are instrumental in clearance of these microbial pathogens, thus suggested as one of the most important contributing factor in determining the disease outcome. Dendritic cell-associated C-type lectin-1 (Dectin-1) is an import...

The innate recognition of fungal pathogens is mediated by a variety of pattern recognition receptors (PRRs), although much interest has focussed on the Toll-like Receptors (TLR). More recently, however, there is growing appreciation that the non-TLRs have a major role in the control of infection with these organisms. One such molecule is Dectin-1, a C-type lectin-like receptor which induces num...

One of the first steps toward mounting an effective immune response to Mycobacterium tuberculosis (Mtb) is recognition of the pathogen through pattern-recognition receptors (PRRs) expressed by innate immune cells. Activation of the PRR Dectin-1 by an unknown mycobacterial ligand triggers an intracellular signaling cascade involving numerous proteins, including spleen tyrosine kinase, protein ki...

C-type lectin receptors (CLRs) comprise a large superfamily of proteins, which recognise a diverse range of ligands, and are defined by the presence of at least one C-type lectin-like domain (CTLD). Of particular interest are the single extracellular CTLD-containing receptors of the 'Dectin-1' and 'Dectin-2' clusters, which associate with signalling adaptors or possess integral intracellular si...

Aspergillus species are a major worldwide cause of corneal ulcers, resulting in visual impairment and blindness in immunocompetent individuals. To enhance our understanding of the pathogenesis of Aspergillus keratitis, we developed a murine model in which red fluorescent protein (RFP)-expressing A. fumigatus (Af293.1RFP) conidia are injected into the corneal stroma, and disease progression and ...

Invasive mold infections (IMI) are among the most devastating complications following chemotherapy and hematopoietic stem cell transplantation (HSCT), with high mortality rates. Yet, the molecular basis for human susceptibility to invasive aspergillosis (IA) and mucormycosis remain poorly understood. Herein, we aimed to characterize the immune profile of individuals with hematological malignanc...

In response to infection by fungal pathogens, the innate immune system recognises specific fungal pathogen associated molecular patterns (PAMPs) via pattern recognition receptors including the C-type lectin dectin-1 and members of the Toll Like Receptor (TLR) family. Stimulation of these receptors leads to the induction of both pro- and anti-inflammatory cytokines. The protein kinases MSK1 and ...
