TY - JOUR. T1 - Importance of the Candida albicans cell wall during commensalism and infection. AU - Gow, N.A.R.. AU - Hube, B.. PY - 2012/8. Y1 - 2012/8. N2 - An imbalance of the normal microbial flora, breakage of epithelial barriers or dysfunction of the immune system favour the transition of the human pathogenic yeast Candida albicans from a commensal to a pathogen. C. albicans has evolved to be adapted as a commensal on mucosal surfaces. As a commensal it has also acquired attributes, which are necessary to avoid or overcome the host defence mechanisms. The human host has also co-evolved to recognize and eliminate potential fungal invaders. Many of the fungal genes that have been the focus of this co-evolutionary process encode cell wall components. In this review, we will discuss the transition from commensalism to pathogenesis, the key players of the fungal cell surface that are important for this transition, the role of the morphology and the mechanisms of host recognition and ...

PY - 2015/1/1. Y1 - 2015/1/1. N2 - Candida albicans is a diploid, polymorphic yeast, associated with humans, where it mostly causes no harm. However, under certain conditions it can cause infections ranging from superficial to life threatening. This ability to become pathogenic is often linked to the immune status of the host as well as the expression of certain virulence factors by the yeast. Due to the importance of C. albicans as a pathogen, determination of the molecular mechanisms that allow this yeast to cause disease is important. These studies rely on the ability of researchers to create deletion mutants of specific genes in order to study their function. This article provides a critical review of the important techniques used to create deletion mutants in C. albicans and highlights how these ...
Ability of Candida albicans mutants to induce Staphylococcus aureus vancomycin resistance during polymicrobial biofilm formation.: Candida albicans and Staphylo
Abstract Background The fungal pathogen Candida albicans is frequently seen in immune suppressed patients, and resistance to one of the most widely used antifungals, fluconazole (FLC), can evolve rapidly. In recent years it has become clear that plasticity of the Candida albicans genome contributes to drug resistance through loss of heterozygosity (LOH) at resistance genes and gross chromosomal rearrangements that amplify gene copy number of resistance associated genes. This study addresses the role of the homologous recombination factors Rad54 and Rdh54 in cell growth, DNA damage and FLC resistance in Candida albicans. Results The data presented here support a role for homologous recombination in cell growth and DNA damage sensitivity, as Candida albicans rad54Δ/rad54Δ mutants were hypersensitive to MMS and menadione, and had an aberrant cell and nuclear morphology. The Candida albicans rad54Δ/rad54Δ mutant was defective in invasion of Spider agar, presumably due to the ...

The putative vesicle transport protein Vac1p of the human pathogenic yeast Candida albicans plays an important role in virulence. To determine the cellular functions of Vac1p, a null mutant was generated by sequential disruption of both alleles. The vac1 null mutant strain showed defective endosomal vesicle transport, demonstrating a role of Vac1p in protein transport to the vacuole. Vac1p also contributes to resistance to metal ions, as the null mutant strain was hypersensitive to Cu(2+), Zn(2+) and Ni(2+). In addition, the loss of Vac1p affected several virulence factors of C. albicans. In particular, the vac1 null mutant strain showed defective hyphal growth, even when hyphal formation was induced via different pathways. Furthermore, Vac1p affects chlamydospore formation, adherence to human vaginal epithelial cells, and the secretion of aspartyl proteinases (Saps). Avirulence in a mouse model of systemic infection of the vac1 null mutant strongly suggests that Vac1p of C. albicans is ...
The dimorphic fungus Candida albicans is a commensal of the human oral, gastrointestinal, vaginal, cutaneous, and mucosal surfaces. In immunocompetent as well as immunocompromised individuals, C. albicans causes cutaneous or subcutaneous infections such as vaginitis or oral thrush or infections of the nails and skin. In patients receiving broad-spectrum antibiotics or undergoing cancer chemotherapy, C. albicans can enter the bloodstream to cause serious systemic invasive disease (6, 38). Due to the difficulty in identifying antifungal targets unique to fungi that are not shared with the human host, only a restricted number of antifungal agents have been widely used for treating C. albicans systemic infections (12, 32). One such target unique to fungi is the sterol cell membrane component ergosterol.. Fluconazole is a member of the azole class of drugs that target an essential enzyme (Erg11; lanosterol 14α-demethylase) in the ergosterol biosynthetic pathway (36, 37). Fluconazole is the most ...
Abstract: The human opportunistic pathogen Candida albicans colonizes biotic and abiotic surfaces, grows within tissue, and proliferates in blood. C. albicans alters its morphology, growing as yeast or elongated filamentous hyphae, and its colony structure, forming dispersed suspensions, colonies or biofilms, to exploit its surroundings and to spread to additional areas. Understanding the response... read mores and their environmental triggers grants valuable insight into pathogenesis. In a phenotype reminiscent of the invasive filamentation of human tissue during candidiasis, C. albicans filaments in response to growth in contact with a semi-solid agar matrix. The transmembrane protein Dfi1p is required for this response. To better understand the role of Dfi1p, the cues that promote Dfi1p-dependent filamentation were identified and analyzed. Different aspects of the physical environment, such as pressure and viscosity, were independently varied and tested to identify the physical features of ...
Recent sequencing and assembly of the genome for the fungal pathogen Candida albicans used simple automated procedures for the identification of putative genes. We have reviewed the entire assembly, both by hand and with additional bioinformatic resources, to accurately map and describe 6,354 genes and to identify 246 genes whose original database entries contained sequencing errors (or possibly mutations) that affect their reading frame. Comparison with other fungal genomes permitted the identification of numerous fungus-specific genes that might be targeted for antifungal therapy. We also observed that, compared to other fungi, the protein-coding sequences in the C. albicans genome are especially rich in short sequence repeats. Finally, our improved annotation permitted a detailed analysis of several multigene families, and comparative genomic studies showed that C. albicans has a far greater catabolic range, encoding respiratory Complex 1, several novel oxidoreductases and ketone body degrading
Mononuclear phagocytic cells (macrophages) are important cells of the immune system that are responsible for host defense to pathogenic organisms and infection. One pathogenic microorganism that can activate macrophages is the dimorphic fungus, Candida albicans. It is a major cause of candidiasis and is responsible for the development of serious, potentially fatal disease in predisposed patients. Upon activation, macrophages secrete inflammatory mediators, including the cytokines tumor necrosis factor alpha (TNF-α) and interleukin 1 (IL-1). Adenosine is an important physiological molecule that can modulate the function of macrophages by altering the amounts of cytokine produced. The effect of adenosine on the production of TNF-α and IL-1 by peritoneal macrophages was studied. Murine peritoneal macrophages stimulated with Candida albicans yeast cells secreted significant amounts of TNF-α and IL-1 over a 14 hr period. Various concentrations of adenosine (10-1000 μM) dose-dependently inhibited the

Mannan is a prominent structural component displayed on the cell surface of C. albicans yeast cells (4), and antimannan IgG is present ubiquitously in the general human population (10, 14, 23). Previously, we showed that this naturally occurring antimannan IgG is required for activation of the classical complement pathway when C. albicans is incubated in NHS (40). We now present evidence that this naturally occurring antimannan IgG also regulates activation of the alternative pathway byC. albicans yeast cells. In NHS that is deficient in antimannan antibodies and lacks classical pathway activity as a result of EGTA chelation of serum Ca2+, addition of exogenous antimannan IgG accelerated C3 binding via the alternative pathway in a dose-dependent manner (Fig. 1 and 3). This accelerating effect of antimannan IgG was confirmed in a serum-free complement binding medium that consisted of only purified proteins of the alternative pathway (Fig. 2) as well as in immunofluorescence analysis (Fig. 5). A ...
Cytolytic proteins and peptide toxins are classical virulence factors of several bacterial pathogens which disrupt epithelial barrier function, damage cells and activate or modulate host immune responses. Such toxins have not been identified previously in human pathogenic fungi. Here we identify the first, to our knowledge, fungal cytolytic peptide toxin in the opportunistic pathogen Candida albicans. This secreted toxin directly damages epithelial membranes, triggers a danger response signalling pathway and activates epithelial immunity. Membrane permeabilization is enhanced by a positive charge at the carboxy terminus of the peptide, which triggers an inward current concomitant with calcium influx. C. albicans strains lacking this toxin do not activate or damage epithelial cells and are avirulent in animal models of mucosal infection. We propose the name Candidalysin for this cytolytic peptide toxin; a newly identified, critical molecular determinant of epithelial damage and host recognition ...
Candida albicans is part of the human microflora. Excessive and unimpeded growth is generated by a disruption of the sensitive balance and manifests itself in form of oral and/or vaginal soor. Spread of Candida in body tissues causes a systemic candidiasis. Even though there are more than 100 species of Candida, only 7 have been isolated with greater frequency from medical samples. In over 80% of the fungus isolates, Candida albicans and Candida tropicalis are found. Due to colonization of mucous membranes with Candida albicans and its passage into the hosts blood stream, the humoral immune system is stimulated, which results in the production of antibodies against Candida albicans. Generally, shortly after the antigen infringement, Candida albicans-specific IgM-antibodies are produced which are followed by an increase in specific IgG antibodies. Excessive infection of mucous membranes can lead to a high titer of Candida albicans-specific IgA-antibodies.. Test principle: ...

Introduction Candida albicans is a normal flora found in respiratory, gastrointestinal tract, mucous membranes, vagina, urethra, and skin. If the immune system becomes compromised, Candida albicans can infiltrate the bloodstream and diffuse to organs such as kidney, heart and brain [1]. Several diseases caused by Candida albicans are vulvaginistis candiduria, gastrointestinal candidiasis that can cause gastric ulcers and cancer [2]. Candida albicans forms biofilms due to an overdose of antifungal consumption [3]. Biofilms as a Candida albicans protection cause the body to exhibit toward immune system and antifungal agents. Biofilms can absorb the nutrients of the host cell therefore promote the growth colonies. The growth of biofilms is along with the increase of clinical infection in the host cell.. Fungal infections can be treated with the proper use of antifungal agents. The use of antifungal agents should be accompanied by caution for the dangers of biofilm resistance. A new of antifungal ...
The opportunistic human pathogen Candida albicans causes both superficial and life threatening systemic infections and is a leading cause of fungal disease in immunocompromised individuals such as those with AIDS. C. albicans can grow in different cell shapes, also known as morphologies, including yeast-like cells and a variety of filamentous forms, such as true hyphae and pseudohyphae. Yeast, hyphae and pseudohyphae, have been observed at the sites of Candida infection and there is strong evidence that morphogenesis, the transition between yeast and filamentous growth forms, is essential for its virulence. Many studies have implicated the second messenger molecule cAMP in the regulation of morphogenesis due to its role in activating filamentation. Our lab and others have previously characterized the impact of the negative regulators, Nrg1, Rfg1, and Tup1 on the expression of HWP1, a hyphal specific gene. The goal of this project is to characterize whether the addition of exogenous cAMP will ...
Cell-substrate adherence is a fundamental property of microorganisms that enables them to exist in biofilms. Our study focuses on adherence of the fungal pathogen Candida albicans to one substrate, silicone, that is relevant to device-associated infection. We conducted a mutant screen with a quantitative flow-cell assay to identify thirty transcription factors that are required for adherence. We then combined nanoString gene expression profiling with functional analysis to elucidate relationships among these transcription factors, with two major goals: to extend our understanding of transcription factors previously known to govern adherence or biofilm formation, and to gain insight into the many transcription factors we identified that were relatively uncharacterized, particularly in the context of adherence or cell surface biogenesis. With regard to the first goal, we have discovered a role for biofilm regulator Bcr1 in adherence, and found that biofilm regulator Ace2 is a major functional target of

These were a human T-cell line (CEM), a mouse T-cell line (YAC-1), a human B-cell line (LAZ), and a human erythroleukemic tumour cells (K562), whereas 2 cell lines of professional phagocytosis were used as controls, a human macrophage cell line (THP1) and a mouse macrophage cell line (P388D1). Tumour cells were mixed with candida albicans at a ratio of 10:1 of candida to tumour cells and the percentage of tumour cells that had attached/phagocytosed candida was determined. After 4 h coculture with candida, tumour cells not of T-cell origin (LAZ and K562) showed ...
In response to changes in ambient pH the opportunistic pathogen Candida albicans differentially expresses a number of genes. The response to pH affects morphological differentiation and virulence. The pathway controlling the pH response terminates in the zinc-finger containing transcription factor encoded by RIM101/PRR2. By analogy to the pH response pathway of Aspergillus nidulans, PRR1 of C. albicans encodes a protein that is presumably required to convert Rim101p from an inactive to an active form by proteolytic removal of a C-terminal peptide. A prr1Delta mutant is compromised in its ability to differentiate into the filamentous form. Spontaneous phenotypic revertants of a prr1Delta mutant were selected by their ability to form filamentous colonies. These mutants were also found to be defective in pH-dependent gene expression. Each of the eight mutants examined contained a heterozygous dominant mutation at the RIM101 locus. This was demonstrated genetically in all of the mutants, and ...
Candida albicans, an opportunistic fungal pathogen of humans, is dependent upon iron for growth. Consequently, human serum inhibits C. albicans growth due to the presence of high affinity iron-binding proteins that sequester serum iron, making it unavailable for use by the organism. We report that in the inhibitory environment of human serum, the growth of C. albicans can be restored by the addition of exogenous hemoglobin or heme, but not by protoporphyrin IX, the heme precursor that does not contain iron. We further report that C. albicans can utilize cell surface proteins that are homologues of the mammalian complement receptors (CR) to rosette complement-coated red blood cells (RBC) and obtain RBC-derived iron for growth. The ability of Candida to acquire RBC-derived iron under these conditions is dependent upon Candida-RBC rosetting mediated by CR-like molecules. Unopsonized RBC do not support Candida growth in serum, and restoration of Candida growth in serum by complement-opsonized RBC is ...

Candida albicans is a common fungal pathogen of humans that colonizes the skin and mucosal surfaces of most healthy individuals. Until recently, little was known about the mechanisms by which mucosal antifungal defences tolerate colonizing C. albicans but react strongly when hyphae of the same microorganism attempt to invade tissue. In this Review, we describe the properties of yeast cells and hyphae that are relevant to their interaction with the host, and the immunological mechanisms that differentially recognize colonizing versus invading C. albicans ...

The killer effect of 37 species of Candida, Cryptococcus, Hansenula, Pichia, Rhodotorula, Saccharomyces, and Trichosporon on 100 Candida albicans isolates of human and animal origin was studied. All of the C. albicans cultures were sensitive to one or more killer yeasts. The factors affecting the killer phenomenon on C. albicans were investigated for realizing a simple system for the differentiation of the 100 C. albicans isolates. By using this system, it was possible to differentiate up to 512 isolates of C. albicans according to their susceptibility to the killer effect of nine selected killer yeasts. The use of this method as an epidemiological marker in the case of presumptive nosocomial infections due to C. albicans is also reported. ...
TY - JOUR. T1 - Candida albicans stimulates arachidonic acid liberation from alveolar macrophages through α-mannan and β-glucan cell wall components. AU - Castro, M.. AU - Ralston, N. V C. AU - Morgenthaler, Timothy Ian. AU - Rohrbach, M. S.. AU - Limper, Andrew Harold. PY - 1994. Y1 - 1994. N2 - Candida albicans is an increasingly important fungal pathogen. Alveolar macrophages respond to fungal components such as zymosan by releasing arachidonic acid (AA) and AA metabolites. However, few studies have evaluated the effect of whole fungi on macrophage eicosanoid metabolism. We hypothesized that macrophages respond to C. albicans by releasing AA and generating AA metabolites as a consequence of interaction of mannose and β- glucan receptors with fungal cell wall components. [14C]AA-labeled rabbit alveolar macrophages released AA following stimulation with either live or heat-killed C. albicans. High-pressure liquid chromatography analysis revealed that 55% of the AA released was metabolized ...
A central theme in biology is to understand how different signaling outputs can be accomplished by changes to signal transduction pathways. Here, we examined epigenetic differences between two cell states in the human fungal pathogen Candida albicans. We show that cells in the "white" state are sterile due to multiple bottlenecks in MAPK signaling relative to mating-competent "opaque" cells. Alleviation of these bottlenecks by reverse engineering effectively converts sterile white cells into sexually competent cells. These results have broad implications for understanding how epigenetic changes can impact MAPK expression and signaling output, including events associated with tumorigenesis. We also propose a model for how the white-opaque switch gained control of sexual reproduction in Candida during evolution.. ...
Link to Pubmed [PMID] - 16040234. Res. Microbiol. 2005 Aug;156(7):822-9. Phospholipases play an important role as virulence factors in human pathogens. Candida albicans, the major fungal pathogen of humans, encodes phospholipases of type A, B, C and D. Type B Plb2 and type D Pld1 phospholipases have been shown to contribute to virulence in this organism. We analyzed, in C. albicans, PLC2 and PLC3, two highly conserved genes coding for phosphatidylinositol-dependent phospholipases C with homology to the known virulence factor PlcA in the human pathogen Listeria monocytogenes. We show that expression of PLC2 and PLC3 is upregulated under different filament-inducing conditions and in the constitutive filamentous mutant tup1Delta. In order to analyze PLC2 and PLC3 function in C. albicans, we constructed strains that carry PLC2 or PLC3 under a constitutive promoter and strains that lack all four PLC2/3 alleles. These strains were not affected in their ability to produce filaments under non-inducing ...
To determine whether the C. albicans MTL gene cluster was required for the a1/α2-like repression activity, theGFP reporters were transformed into MTLa1deletion strains and evaluated for fluorescence. In contrast to the wild-type C. albicans strains, the MTLa1 mutant strains showed the same levels of fluorescence for all of the reporter constructs, indicating that the MTLa1 gene is required for the transcriptional repression activity (Fig. 4). Similar behavior was seen for both the complete deletion of the MTLa1 gene and for the MTLa1 homeodomain deletion, consistent with the DNA-binding domain of a1 being required for the repression activity (9). Northern (RNA) analysis also showed that transcription from the reporter constructs containing the functional hsg operators was derepressed in the MTLa1deletion mutants compared with the wild-type strain; however, in the absence of a1, the functional hsg operators still showed a slight amount of repression when compared with the mutated hsg operators ...
Phosphomannosylation is a modification of cell wall proteins that occurs in some species of yeast-like organisms, including the human pathogen Candida albicans. These modified mannans confer a negative charge to the wall, which is important for the interactions with phagocytic cells of the immune systems and cationic antimicrobial peptides. In Saccharomyces cerevisiae, the synthesis of phosphomannan relies on two enzymes, the phosphomannosyltransferase Ktr6 and its positive regulator Mnn4. However, in C. albicans, at least three phosphomannosyltransferases, Mnn4, Mnt3 and Mnt5, participate in the addition of phosphomannan. In addition to MNN4, C. albicans has a MNN4-like gene family composed of seven other homologous members that have no known function. Here, using the classical mini-Ura-blaster approach and the new gene knockout CRISPR-Cas9 system for gene disruption, we generated mutants lacking single and multiple genes of the MNN4 family; and demonstrate that, although Mnn4 has a major impact on the
Candida overgrowth is an infestation of the Candida albicans yeast. Everyone has a certain amount of Candida in their digestive tract, but if the Candida increases beyond a certain level, it cause problems. The main symptoms are chronic low energy, low-grade fevers, variable digestion, weak immune system and food allergies. These symptoms can be confused with other conditions, especially complaints relating to general digestive weakness and immunity disorders, so it is best to have a medical examination to verify whether Candida is present at significant levels.
Candida dubliniensis is the species that is most closely related to Candida albicans. Despite their close phylogenetic relatedness, epidemiological and infection model data suggest that C. albicans is a far more successful pathogen. The reasons for this disparity in virulence are still unclear, however, it has been shown that C. dubliniensis is less able than C. albicans to produce hyphae under a wide range of in vitro and in vivo conditions. The purpose of this study was to investigate the comparative effects of glucose/galactose and methionine on morphogenesis in the two species ...

Candida albicans secreted aspartyl proteinases (Sap), products of the SAP genes, which are presumed to act as virulence factors. In the C. albicans strain WO-1, the ability to secrete Sap1 is regulated with switch phenotype, another putative virulence factor. KpnI restriction fragment length polymorphisms differentiate between several distinct SAP1 alleles in laboratory and clinical strains. Both SAP1 alleles from strain WO-1 along with their 5- and 3-flanking regions were cloned and sequenced, as were both alleles from another strain, SS. The 5-flanking regions were remarkably similar in all four of the sequenced alleles over approximately 1,500 nucleotides. S1 analysis revealed that both alleles of WO-1 are transcribed. Characterization of the one allele from strain WO-1 identified a 284-nucleotide insertion flanked by 8-bp direct repeats that shows homology to the CARE2 repetitive element and that is not present in the other alleles. Characterization of the SAP1 alleles also identified a ...

The Candida antigen CR3-RP (complement receptor 3-related protein) is supposed to be a mimicry protein because of its ability to bind antibody directed against the α subunit of the mammalian CR3 (CD11b/CD18). This study aimed to (i) investigate the specific humoral isotypic response to immunization with CR3-RP in vivo in a rabbit animal model, and (ii) determine the role of CR3-RP in the adherence of Candida albicans in vitro using the model systems of buccal epithelial cells (BECs) and biofilm formation. The synthetic C. albicans peptide DINGGGATLPQ corresponding to 11 amino-acids of the CR3-RP sequence DINGGGATLPQALXQITGVIT, determined by N-terminal sequencing, was used for immunization of rabbits to obtain polyclonal anti-CR3-PR serum and for subsequent characterization of the humoral isotypic response of rabbits. A significant increase of IgG, IgA and IgM anti-CR3-RP specific antibodies was observed after the third (P<0.01) and the fourth (P<0.001) immunization doses. The elevation of IgA
Candida albicans CZF1 protein: Candida albicans gene that interferes with Saccharomyces cerevisiae mating factor-induced cell cycle arrest; amino acid sequence given in first source
Background: A majority of the population has been shown to carry Candida albicans within their normal oral flora; however, very few people suffer from oral Candida infections. Past studies reveal that long-term antibiotic therapy markedly increases the hosts susceptibility to oral thrush, suggesting that bacteria play a vital role in maintaining a healthy oral environment. Objective: The aim of this study was to isolate and identify specific bacteria obtained from healthy individuals that may be involved in suppressing C. albicans growth under normal oral conditions. Method: Various bacterial strains, isolated and purified from the saliva of healthy individuals, were co-cultured with C. albicans wild type strain 5314. The bacterial strains that most effectively suppressed yeast growth were identified using polymerase chain reaction and DNA sequencing. Results: Our results indicate that all of the bacterial strains isolated were able to suppress yeast growth to some extent; however, ...
Candida albicans (C. albicans) is a common fungal pathogen causing both localised and systemic infections. The majority of these infections are promoted by biofilm formation, providing a protective matrix for the embedded fungi thereby evading the host immune defence and promoting resistance against anti-mycotic ag
Author Summary The innate immune system represents a key barrier that fungal pathogens such as Candida albicans must overcome in order to disseminate through the host. C. albicans cells phagocytosed by macrophages initiate a complex program that involves a large-scale reprogramming of metabolism and transcription and results in the switch to a hyphal form that can penetrate and kill the macrophage. Though a number of signals are known to induce this morphological transition in vitro, what does so following phagocytosis has been unclear. We previously showed that C. albicans rapidly neutralizes acidic, nutrient-poor media that resembles the phagolysosome and that this is deficient in mutants impaired in amino acid import due to a mutation in STP2. In this paper, we investigate whether this happens within the macrophage as well. We show here that, in contrast to wild-type cells, stp2Δ mutants occupy an acidic phagosome and are unable to initiate hyphal differentiation. Because of this, they are more
Candida albicans is the most prevalent fungal pathogen of humans. In addition to causing mucosal infections, such as thrush and vaginitis, in relatively healthy individuals, it causes life-threatening systemic infections in premature infants, surgical patients, chemotherapy patients, and other patients with weakened immune systems. Mortality from systemic infections approaches 30% despite appropriate therapy with the available antifungal agents (59). C. albicansgrows in a number of morphologic forms, including ellipsoidal, yeast-form blastospores and filamentous forms that include elongated budding pseudohyphae and parallel-sided germ tubes that give rise to true hyphae (reviewed in reference 58). The ability ofC. albicans to switch between these morphologies is correlated with its virulence (reviewed in references 16, 51, and58). The transition from yeast to hyphal growth occurs in response to a broad range of environmental stimuli. Potent stimuli include one or more constituents of mammalian ...
Candidalysin is a cytolytic peptide toxin secreted by the invasive form of the human pathogenic fungus, Candida albicans. Candidalysin is critical for mucosal and systemic infections and is a key driver of host cell activation, neutrophil recruitment and Type 17 immunity. Candidalysin is regarded as the first true classical virulence factor of C. albicans but also triggers protective immune responses. This review will discuss how candidalysin was discovered, the mechanisms by which this peptide toxin contributes to C. albicans infections, and how its discovery has advanced our understanding of fungal pathogenesis and disease.. ...
Candida albicans is an important human pathogen, causing opportunistic infections. The adhesion of planktonic cells to a substrate is the first step for biofilm development. The antimicrobial peptide (AMP) Psd1 is a defensin isolated from Pisum sativum seeds. We tested the effects of this AMP on C. albicans biofilms and planktonic cells, comparing its activity with amphotericin B and fluconazole. Three C. albicans variants were studied, one of them a mutant deficient in glucosylceramide synthase, conferring resistance to Psd1 antifungal action. Atomic force microscopy (AFM) was used to assess morphological and biomechanical changes on fungal cells. Surface alterations, with membrane disruption and leakage of cellular contents, were observed. Cytometry assays and confocal microscopy imaging showed that Psd1 causes cell death, in a time and concentration-dependent manner. These results demonstrate Psd1 pleiotropic action against a relevant fungal human pathogen, suggesting its use as natural antimycotic

N-Cadherin and Endocytosis in Candida albicans. I. Introduction/Review. Candida albicans, diploid yeast-like fungi, are harmless commensals of the human body; however, it can also be the causal agent of opportunistic and genital infections known as candidiasis or moniliasis or trush. General-purpose genotype strains (GPGs) of C. albicans has been demonstrated to cause the pathogenic disease more significantly compared to other strains and the predominating effect may be attributed to the ability of the strains to replace the existing commensals (Schmidt and others 1999) and to the differences in the gene region located on 60 alleles of ALS7 ORF or the so-called hypermutable contingency genes (Zhang and others 2003).. The hymatogenous distribution of C. albicans causes allergies in healthy individuals and microabscesses in immunocompromized ...

Mutants were obtained from strains B311 and B792 and from four strains isolated from patients with acquired immunodeficiency syndrome. All 15 tested mutants retained characteristic sugar assimilation patterns. All but one of the mutants retained the ability to form germ tubes and chlamydospores. Two mutants from an acquired immunodeficiency syndrome-derived isolate were deficient in binding complement ligands iC3b and C3d, whereas another mutant was deficient in binding ligand iC3b but not 3d. The hyphae of these three mutants lacked antigens when ...
THE opportunistic fungal pathogen, Candida albicans, grows invasively in tissues of candidiasis patients by converting from budding yeast form cells to filamentous forms. The ability to convert from one morphology to another is important for virulence (Sobelet al. 1984; Shepherd 1985; Ryley and Ryley 1990; Lebereret al. 1997; Loet al. 1997). To understand the mechanisms by which filamentous growth is stimulated during infection, regulation of hyphal development has been studied extensively (for review, see Gow 1997). Conditions that promote hyphal growth in the laboratory include growth at elevated temperature in medium containing special components. In the absence of these conditions, growth within a matrix also promotes hyphal growth (Brownet al. 1999). The embedded condition may simulate conditions encountered by the pathogen during growth in human tissue.. Several genes whose products regulate filamentous growth have been identified (for review, see Ernst 2000), including CPH1 (Liuet al. ...
Recent studies indicate that mitochondrial functions impinge on cell wall integrity, drug tolerance, and virulence of human fungal pathogens. However, the mechanistic aspects of these processes are poorly understood. We focused on the mitochondrial outer membrane SAM (Sorting and Assembly Machinery) complex subunit Sam37 in Candida albicans. Inactivation of SAM37 in C. albicans leads to a large reduction in fitness, a phenotype not conserved with the model yeast Saccharomyces cerevisiae. Our data indicate that slow growth of the sam37ΔΔ mutant results from mitochondrial DNA loss, a new function for Sam37 in C. albicans, and from reduced activity of the essential SAM complex subunit Sam35. The sam37ΔΔ mutant was hypersensitive to drugs that target the cell wall and displayed altered cell wall structure, supporting a role for Sam37 in cell wall integrity in C. albicans. The sensitivity of the mutant to membrane-targeting antifungals was not significantly altered. The sam37ΔΔ mutant was ...
Candida albicans is able to play a destructive game of hide and seek with your immune system by making changes to its cell walls so that it can escape detection.. You are born with an innate immune system that recognizes invaders into your body. Pathogens have proteins called antigens on their surface, which show your immune system which cells they need to attack.. Your immune system uses a system including special sensors called Pattern Recognition Receptors (PRRs). They allow your immune system to figure out precisely whether the invader is a fungus, virus, or bacteria, and decide on the most appropriate immune response.. Candida cell walls consist of a matrix of α- and β-mannans. The β-glucan on the fungal cell wall is recognized by your immune system. This triggers a process known as phagocytosis, where the immune cells neutrophils and macrophages consume the pathogen. (10). It is this process of phagocytosis that Candida has managed to avoid. It hides the β-glucan on its surface, ...

SUMMARY: The enzymes of N-acetyl-D-glucosamine (GlcNAc) metabolism, GlcNAc-6-phosphate deacetylase and GlcN-6-phosphate deaminase were found to be inducible in Candida albicans. The pattern of induction for these enzymes was the same under conditions of germ-tube formation (37 °C) and where yeast cells metabolized GlcNAc with no change in morphology (28 °C); this indicates that these enzymes are not control points in the dimorphic development of C. albicans. During induction there was a 40- and 25-fold increase in specific activity for the deacetylase and the deaminase, respectively, and the maximum specific activity corresponded to the time when all the GlcNAc had been metabolized. The presence of lomofungin (an inhibitor of transcription) or trichodermin (an inhibitor of translation) in cell suspensions of C. albicans containing GlcNAc prevented the increase in specific activity of these enzymes. 2-Deoxyglucose inhibited germ-tube formation, partially inhibited the induction of the deacetylase (43%)

Purpose: : To evaluate virulence of Candida albicans homozygous mutants in a murine keratitis model. Methods: : Corneas of 3-5 immunocompetent adult female BALB/c mice were topically inoculated with a wild-type strain of C. albicans, a transposon-induced homozygous mutant (rbt1-/-), its parental control (DAY286), knockout homozygous mutants BCa7-4 (rbt1-/-) and BCa11-3 (rbt4-/-), or its parental control (CAF2-1). The fungal load inoculated onto the cornea was at concentrations of 105 or 106 colony-forming units (cfu) following corneal scarification. Mock-inoculated, scarified eyes served as controls. Eyes were scored daily for 8 days post infection (PI) using a 12-point scale to categorize corneal disease. Results: : At 106 cfu, wild-type C. albicans human isolate (SC5314) had a high degree of virulence in the murine cornea, and the fungal strains used to generate the mutants (DAY286 and CAF2-1) had similar corneal pathogenicity (P , 0.43 and , 0.11, respectively). Likewise, the rbt1-/- mutant ...
Immunological memory in vertebrates is often exclusively attributed to T and B cell function. Recently it was proposed that the enhanced and sustained innate immune responses following initial infectious exposure may also afford protection against reinfection. Testing this concept of "trained immunity," we show that mice lacking functional T and B lymphocytes are protected against reinfection with Candida albicans in a monocyte-dependent manner. C. albicans and fungal cell wall β-glucans induced functional reprogramming of monocytes, leading to enhanced cytokine production in vivo and in vitro. The training required the β-glucan receptor dectin-1 and the noncanonical Raf-1 pathway. Monocyte training by β-glucans was associated with stable changes in histone trimethylation at H3K4, which suggests the involvement of epigenetic mechanisms in this phenomenon. The functional reprogramming of monocytes, reminiscent of similar NK cell properties, supports the concept of "trained immunity" and may be ...
Candida albicans is the most prominent fungal pathogen in immuno-compromised patients, and systematic infections are often fatal. One of the most important features of C. albicans is its ability to switch between different morphological forms such as yeast, pseudo-hyphae, and hyphae. A diverse range of growth conditions can induce the growth switch from yeast to hyphae via several regulatory pathways, while some other conditions and perturbation of the cell cycle progression can lead to pseudohyphal growth. In this thesis, we report that a range of genotoxic insults that disturb cell cycle progression induced pseudohyphal growth of C. albicans, including the inhibition of DNA synthesis by hydroxyurea (HU) or aphidicolin (AC), the depletion of ribonucleotide reductase subunit Rnr2, and DNA damages by methylmethane sulphonate (MMS) and ultraviolet (UV). In spite of all the knowledge of filamentous growth, the pathways which are required for the pseudohyphal growth in C. albicans are still unknown. ...
Candida albicans is a human commensal organism that can cause life-threatening systemic infections in severely ill patients.

Several different repetitive DNA sequences have been isolated from the pathogenic yeast Candida albicans. These include two families of large dispersed repeat sequences (Ca3, Ca24) and a short (23-bp) tandemly repeated element (Ca7) associated with C. albicans telomeres. In addition, a large subtelomeric repeat (WOL17) has been cloned. DNA fragments containing the telomeric repeats are highly variable among different C. albicans strains. We have shown that the Ca3 repeat is relatively more stable and is suitable for use as a species-specific and strain-specific probe for C. albicans. ...

Systems biology approaches can be used to study the regulatory interactions occurring between many components of the biological system at the whole-genome level and decipher the circuitries implicated in the regulation of cellular processes, including those imparting virulence to opportunistic fungi. Candida albicans (C. albicans) is a leading human fungal pathogen. It undergoes morphological switching between a budding yeast form and an elongated multicellular hyphal form. This transition is required for C. albicans ability to cause disease and is regulated through highly interconnected regulatory interactions between transcription factors (TFs) and target genes. The chromatin immunoprecipitation (ChIP)-High-throughput sequencing (Seq) technology (ChIP-Seq) is a powerful approach for decoding transcriptional regulatory networks. This protocol was optimized for the preparation of ChIP DNA from filamenting C. albicans cells followed by high-throughput sequencing to identify the targets of TFs that
Richard is Professor of Molecular Microbiology at the University of Otago School of Dentistry. He undertook his biochemistry and microbiology training at the University of Cambridge, UK. His main research interest is in oral yeast: how they colonise the oral cavity; how they cause disease; and ways of preventing them causing disease.. Richards particular research interests focus on the human pathogen Candida albicans, which causes both oral candidosis and life-threatening disseminated disease. He uses molecular approaches to determine how C. albicans adheres in the mouth, what makes it pathogenic, how it becomes resistant to antifungal drugs, and how its drug resistance can be overcome. Richard also uses bakers yeast, Saccharomyces cerevisiae, as a tool to investigate fungal membrane protein structure and function. ...

... , Candida is the name for a group of yeasts (a type of fungus) that commonly infect the skin. The name candida refers to the white colour of the organisms in culture . Candidal infection is known as candidiasis, candidosis or moniliasis (monilia is also a genus of ascomycete fungi).
The female human body is an organic machine made of nerve, muscle and bone. It can nurture babies for up to nine months. But, like all machines, it is prone to the occasional malfunction, such as, well, getting candidiasis - better known as a yeast infection, or in this case vaginal thrush. So how do you go about diagnosing yeast infection?. Not Quite Yeast, Actually…. To begin, vaginal thrush is not brought about by yeast. The infection is actually caused by a fungus called Candida albicans which has yeast-like properties. It grows naturally in warm, moist, dark regions of the body, like the mouth and the vagina. Its growth is kept checked by a kind of beneficial bacteria which also grows in the human body. The job of Candida albicans is to search for harmful bacteria and destroy them.. The problem starts when the good bacteria that monitor the growth of Candida albicans die, either because of antibiotics or a weak immune system. Once these bacteria die, Candida albicans grow rapidly and ...
For each part of this study, essential oil from cinnamon leaves was purchased from Ferquima Ind. eCom. (São Paulo, Brazil). Secondary compounds in the essential oil were evaluated with mass spectrometry. Seventeen peaks were measured, with eugenol comprising 82.3% of the oil. In addition, nystatin (Sigma-Aldrich Brasil Ltda.; São Paulo, Brazil) was used as a positive control in the first 2 parts of the study. The minimum inhibitory concentration (MIC) of cinnamon essential oil was determined in 8 strains of Candida albicans and 4 strains ofCandida tropicalis using serial dilutions. Once the MIC was determined, the minimum fungicidal concentration (MFC) was determined by growing the Candida strains in culture with the MIC for cinnamon essential oil. Two additional concentrations of essential oil (MICx2 and MICx4) were tested for MFC determination. The effect of cinnamon essential oil was measured on the roughness and hardness of polished denture-like acrylic samples. One side of each acrylic ...
Here, we describe a protocol for a continuous flow system for C. albicans cultures growing adherent to a plastic surface. The protocol was adapted from a previous method established to simulate blood flow on endothelial cells (Wilson and Hube, 2010). The adapted protocol was used by us for the removal of molecules in C. albicans supernatants, especially farnesol, which accumulate over the time course of incubation and cannot be specifically depleted. The system used, however, allows various applications including the simulation of physiological flow conditions. Several example applications are given on the manufacturers website (https://ibidi.com/perfusion-system/112-ibidi-pump-system.html).

Initially, the CGD biochemical pathways were automatically generated using PathoLogic, a pathway prediction program built into the Pathway Tools. PathoLogic used information about the function of individual Candida gene products from CGD in conjunction with SRIs reference database of biochemical reaction and pathway information, MetaCyc, to create a set of predicted Candida albicans pathways. The starting set of Candida albicans enzymes that was input into the PathoLogic software was generated using the Gene Ontology curation from CGD. PathoLogic then compared the list of enzyme names against SRIs MetaCyc pathway database. For the purpose of generation of pathways for CGD, the software was also configured to consult the set of pathways curated at the Saccharomyces Genome database in addition to the pathways contained in MetaCyc pathway, such that curated S. cerevisiae pathways that are not included in MetaCyc were used as an additional basis for comparison. If Candida albicans contains one or ...

The ALS gene family encodes large cell-surface glycoproteins associated with C. albicans pathogenesis. Als proteins are thought to act as adhesin molecules binding to host tissues. Wide variation in expression levels among the ALS genes exists and is related to cell morphology and environmental conditions. ALS1, ALS3, and ALS4 are three of the four most highly expressed ALS genes. This work describes the production and use of specific high affinity monoclonal antibodies against Als1, Als3, and Als4 to evaluate protein production and localization at both the individual cell and population levels. Production and localization of these proteins is tightly regulated and occurs under specific growth conditions. When examined at a population level, it is clear that cells from the same culture can have different profiles of Als proteins on the cell surface. These results provide a very different view of the Als family than the view held by those who suggest that the Als family functions in antigenic ...
The focus of this symposium was to present new information on the morphogenesis of Candida albicans, particularly how it relates to signal transduction pathways and other genes involved in the regulation of morphogenesis. In addition, we discuss the role of adherence and colonization of the oral cavity by the organism and discuss the role of mannan as an adhesin that recognizes the human red blood cell. C. albicans utilizes at least two signal pathways to regulate its conversion from a yeast form to filamentous growth (hyphae). One of these two pathways is similar to the Saccharomyces cerevisiae pseudohyphal/mating pathway, which utilizes the regulatory protein, Cphlp. The other pathway is not totally defined but requires a second regulatory protein, referred to as Efg1p. Other signal pathways may exist, which include a two-component histidine kinase and response regulator proteins. The latter pathway(s) may include proteins such as Chk1p, Ssk1p, Shi1p and Cos1p/Nik1p. Mutations in strains, which
