Abstract
Candida glabrata is an important pathogen causing invasive infection associated with a high mortality rate. One mechanism that causes the failure of Candida eradication is an increase in regulatory T cells (Treg), which play a major role in immune suppression and promoting Candida pathogenicity. To date, how C. glabrata induces a Treg response remains unclear. Dendritic cells (DCs) recognition of fungi provides the fundamental signal determining the fate of the T-cell response. This study investigated the interplay between C. glabrata and DCs and its effect on Treg induction. We found that C. glabrata β-glucan was a major component that interacted with DCs and consequently mediated the Treg response. Blocking the binding of C. glabrata β-glucan to dectin-1 and complement receptor 3 (CR3) showed that CR3 activation in DCs was crucial for the induction of Treg. Furthermore, a ligand-receptor binding assay showed the preferential binding of C. glabrata β-glucan to CR3. Our data suggest that C. glabrata β-glucan potentially mediates the Treg response, probably through CR3-dependent activation in DCs. This study contributes new insights into immune modulation by C. glabrata that may lead to a better design of novel immunotherapeutic strategies for invasive C. glabrata infection.

Abstract
INTRODUCTION Candida spp. has recently been introduced to interact with conventional carious bacteria, leading to dental caries progression and virulence ability. Evidence regarding the influence of Candida spp. on human dental pulp cell response remains unknown. This study aimed to investigate the effects of Candida albicans mannans on cytotoxicity, cell proliferation, osteogenic differentiation, and inflammatory-related gene expression in human dental pulp cells (hDPCs). METHODS hDPCs were treated with cell wall mannans isolated from C. albicans, Candida krusei, Candida glabrata, Candida tropocalis, Candida parapsilosis, and Candida dubliniensis. Cell viability was performed using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide assay. Osteogenic differentiation- and inflammatory-related gene expression were determined using a real-time polymerase chain reaction. Mineralization was examined using alizarin red S staining. RESULTS The treatment of mannans isolated from C. albicans, C. krusei, C. glabrata, C. tropocalis, C. parapsilosis, and C. dubliniensis at concentrations ranging from 10-100 μg/mL did not affect cytotoxicity or cell proliferation. Mannans isolated from C. albicans, C. glabrata, and C. tropocalis significantly attenuated mineralization. However, cell wall mannans isolated from C. krusei, C. parapsilosis, and C. dubliniensis did not significantly influence mineral deposition in hDPCs. C. albicans cell wall mannans significantly attenuated osteogenic differentiation-related gene expression (RUNX2, ALP, and ENPP1). Interestingly, IL12 messenger RNA expression was significantly upregulated when treated with C. albicans cell wall mannans. The addition of recombinant IL12 significantly decreased mineralization in hDPCs. CONCLUSIONS C. albicans cell wall mannans attenuated osteogenic differentiation in hDPCs and up-regulated inflammatory-related gene IL12 expression.

[PMID: 35958550 PMCID: PMC9362737 DOI: 10.3389/fimmu.2022.950215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Accepted: 06/20/2022] [Indexed: 11/13/2022] Open
Abstract
The objective was to determine the effect of 5% boric acid gel on vaginal Candida albicans (CA) infections in mice and its effect on the local immune system (i.e., Th1, Th2, and Th17). Female mice were divided into four groups, with 10 mice in each group. Mycelial suspensions were administered into the vaginal lumen close to the cervix in groups B, F, and M. Mice in group B were given boric acid gel, and group F was treated with fluconazole gel for 30 min every 12 h. Group M was treated with sterile water, and group N was not given treatment. After the seventh day of treatment, each group was observed with the naked eye, and vaginal lavage fluid and vaginal tissue were collected. Expression levels of cytokines were measured using enzyme-linked immunosorbent assays (ELISA) and immunohistochemistry. Periodic acid Schiff (PAS) staining was used to measure the fungi in vaginal tissues. There were no significant changes in group M. In groups B and F, there was less vaginal injury and less exudate, with group B doing better than group F. The numbers of CA colonies were higher in groups B, F, and M than in group N (P < 0.01). There was less vaginal colonization of CA in group B than in group F (P < 0.01). After the seventh day of treatment, levels of IFN-γ, IL-17, IL-6, TGF-β, IL-4, and IL-10 were significantly greater in groups B, F, and M than in group N (P < 0.001); levels of IFN-γ, IL-17, IL-6, and TGF-β in groups B and F were higher than those of group M (P < 0.01), while IL-4 and IL-10 levels were significantly lower (P < 0.001). The trends of cytokine increases and decreases were more significant in group B than in group F (P < 0.05). Immunohistochemical results were similar to ELISA results. PAS staining revealed that boric acid inhibited hyphal reproduction. The boric acid significantly reduced the symptoms associated with CA vaginal infection. It inhibited the CA growth, prevented vaginal lesions, promoted the secretion of Th1 and Th17 cytokines, and reduced Th2 cytokines.

Abstract
The use of microorganisms for Aflatoxin B1 elimination has been studied as a new alternative tool and it is known that cell wall carried out a critical role. For that reason, cell wall and soluble intracellular fraction of eight yeasts with AFB1 detoxification capability were analysed. The quantitative and qualitative comparative label-free proteomic allowed the identification of diverse common constituent proteins, which revealed that putative cell wall proteins entailed less than 10% of the total proteome. It was possible to characterize different enzymes linked to cell wall polysaccharides biosynthesis as well as other proteins related with the cell wall organization and regulation. Additionally, the concentration of the principal polysaccharides was determined which permitted us to observe that β-glucans concentration was higher than mannans in most of the samples. In order to better understand the biosorption role of the cell wall against the AFB1 , an antimycotic (Caspofungin) was used to damage the cell wall structure. This assay allowed the observation of an effect on the normal growth of those yeasts with damaged cell walls that were exposed to AFB1 . This effect was not observed in yeast with intact cell walls, which may reveal a protective role of this structure against mycotoxins.

Mannan activates tissue native and IgE-sensitized mast cells to proinflammatory response and chemotaxis in TLR4-dependent manner. J Leukoc Biol 2021; 109:931-942. [PMID: 33047839 DOI: 10.1002/jlb.4a0720-452r] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Revised: 09/08/2020] [Accepted: 09/22/2020] [Indexed: 12/18/2022] Open
Abstract
Mast cells take part in host defense against microorganisms as they are numerous at the portal of infection, exert several essential mechanisms of pathogen destruction, and they express pattern recognition receptors. Accumulating evidence indicates that these cells are involved in the control and clearance of bacterial, viral, or parasitic infections, but much less is known about their contribution in defense against fungi. The study was aimed to establish whether mannan, which comprises an outermost layer and major structural constituent of the fungal cell wall, may directly stimulate tissue mast cells to the antifungal response. Our findings indicate that mannan activates mast cells isolated from the rat peritoneal cavity to initiate the proinflammatory response. We found that mannan stimulates mast cells to release histamine and to generate cysteinyl leukotrienes, cytokines (IFN-γ, GM-CSF, TNF), and chemokines (CCL2, CCL3). It also increased the mRNA expression of various cytokines/chemokines. We also documented that mannan strongly activates mast cells to generate reactive oxygen species and serves as a potent chemoattractant for these cells. Furthermore, we established that mannan-induced activity of mast cells is mediated via TLR4 with the involvement of the spleen tyrosine kinase molecule. Taking together, our results clearly support the idea that mast cells act as sentinel cells and crucially determine the course of the immune response during fungal infection. Additionally, presented data on IgE-coated mast cells suggest that exposure to fungal mannan could influence the severity of IgE-dependent diseases, including allergic ones.

Abstract
Oral candidiasis are among the most common noncommunicable diseases, related with serious local and systemic illnesses. Although these infections can occur in all kinds of patients, they are more recurrent in immunosuppressed ones such as patients with HIV, hepatitis, cancer or under long antimicrobial treatments. Candida albicans continues to be the most frequently identified Candida spp. in these disorders, but other non-C. albicans Candida are rising. Understanding the immune responses involved in oral Candida spp. infections is a key feature to a successful treatment and to the design of novel therapies. In this review, we performed a literature search in PubMed and WoS, in order to examine and analyze common oral Candida spp.-bacteria/Candida-Candida interactions and the host immunity response in oral candidiasis.

Abstract
Author: Recently, increasing research in siderophores has been dedicated to their possible medical applications in diagnostics and therapeutics for human pathogenic infections. Fusarinine C (FsC) is a natural hydroxamate siderophore that harbors three amino groups, which allow the easy chemical modification of FsC for the design of novel multifunctional conjugates. However, low production of FsC has hampered its extensive exploitation.Herein, we rewired the FsC biosynthetic pathway in the Aureobasidium melanogenum HN6.2 strain to achieve a self-supplying l-ornithine with component-simplified and enhanced production of extracellular siderophores, for which the FsC accounted for 94%, its final titer being approximately 1.7 g L-1. The convenient acquisition of FsC effectuated our exploitation for its application. We employed in vitro and in vivo assays to show that FsC is an active targeting molecule that acts on the human pathogenic fungi Trichophyton rubrum and Candida albicans; this demonstrates the potential to use FsC for the development of novel antifungal targeting reagents in the future.
