Abstract:
Fungal lectins are a large family of carbohydrate-binding proteins with no enzymatic activity. They play fundamental biological roles in the interactions of fungi with their environment and are found in many different species across the fungal kingdom. In particular, their contribution to defense against feeders has been emphasized, and when secreted, lectins may be involved in the recognition of bacteria, fungal competitors and specific host plants. Carbohydrate specificities and quaternary structures vary widely, but evidence for an evolutionary relationship within the different classes of f

Abstract:
The entomopathogenic fungus Beauveria bassiana and its insect host target represent a model system with which to examine host–pathogen interactions. Carbohydrate epitopes on the surfaces of fungal cells play diverse roles in processes that include adhesion, non-self recognition and immune invasion with respect to invertebrate hosts. B. bassiana produces a number of distinct cell types that include aerial conidia, submerged conidia, blastospores and haemolymph-derived cells termed in vivo blastospores or hyphal bodies.

Actinoporins are potent eukaryotic pore-forming toxins specific for sphingomyelin-containing membranes.

They originate from three animal and two plant phyla and can be classified in three families according to phylogenetic analysis. The sequence similarity is confined to a region from the C-terminal half of the actinoporin molecule and comprises the me

While fungal infections in U.S. hospitals primarily arise among immune compromised patients, there has been an increased incidence in fungal infections that has been complicated by the emergence of drug resistance among fungal pathogens. Even though Dectin-1 functions as one of the primary phagocytic receptors in macrophages for fungal pathogens, the importance of Dectin-1 for controlling fungal pathogens is still unclear and may be pathogen dep

ABSTRACTAspergillusspecies are saprophytic molds causing life-threatening invasive fungal infections in the immunocompromised host. Innate immune recognition, in particular, the mechanisms of opsonization and complement activation, has been reported to be an integral part of the defense against fungi. We have shown that the complement component ficolin-A significantly binds toAspergillusconidia and hyphae in a concentration-dependent manner and was inhibited byN-acetylglucosamine andN-acetylgalactosamine. Calcium-independent binding toAspergillus fumigatusandA. terreuswas observed, but binding

Phytophthora parasitica var. nicotianae produces a 34-kDa glycoprotein elicitor (CBEL) that is localized in the cell wall. A cDNA encoding the protein moiety of this elicitor was cloned and characterized. The deduced amino acid sequence consisted of two direct repeats of a cysteine-rich domain, joined by a Thr/Pro-rich region. Although having no general homology with published sequences, the positions of the cysteine residues in the two repeats show a conserved pattern, similar to that of the cellulose-binding domain of fungal glycanases.

Abstract Plasmacytoid dendritic cells (pDCs) have been implicated as having a role in antifungal immunity, but mechanisms of their interaction with fungi and the resulting cellular responses are not well understood. In this study, we identify the direct and indirect biological response of human pDCs to the fungal pathogen Aspergillus fumigatus and characterize the expression and regulation of antifungal receptors on the pDC surface. Results indicate pDCs do not phagocytose Aspergillus conidia, but instead bind hyphal surfaces and undergo activation and maturation via the upregulation of costim

ABSTRACT Cryparin is a cell-surface-associated hydrophobin of the filamentous ascomycete Cryphonectria parasitica. This protein contains a signal peptide that directs it to the vesicle-mediated secretory pathway. We detected a glycosylated form of cryparin in a secretory vesicle fraction, but secreted forms of this protein are not glycosylated. This glycosylation occurred in the proprotein region, which is cleaved during maturation by a Kex2-like serine protease, leaving a mature form of cryparin that could be isolated from both the cell wall and culture medium.

Abstract:
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 via Syk and CARD9, and contributes to dendritic cell (DC) activation by fungal particles. Unlike Dectin-1, Dectin-2 couples to Syk indirectly, through association with the FcRγ chain. In a model of Candi

Abstract Dendritic cells (DCs) activated via TLR ligation experience metabolic reprogramming, in which the cells are heavily dependent on glucose and glycolysis for the synthesis of molecular building blocks essential for maturation, cytokine production, and the ability to stimulate T cells. Although the TLR-driven metabolic reprogramming events are well documented, fungal-mediated metabolic regulation via C-type Lectin Receptors such as Dectin-1 is not clearly understood. Here, we show that activation of DCs with fungal-associated ligands induces acute glycolytic reprogramming that supports t

Abstract Plants possess an innate immune system enabling them to defend themselves against pathogen attack. The accumulation of newly synthesized pathogenesis-related proteins (PRs) is one of the most studied inducible plant defence response. In this paper, we report on the characterization of a class I PR4 vacuolar protein from Arabidopsis, named AtHEL. The protein has a modular structure consisting of an N-terminal hevein-like domain (CB-HEL) and a C-terminal domain (CD-HEL) that are posttranslationally processed. Both domains show a strong antifungal activity, but they do not have chitinoli
