Special Issue Information

Dear Colleagues,

Fungi are eukaryotic organisms which belong to a distinct kingdom of their own—not plants or animals—this kingdom includes diverse microscopic (e.g., yeasts and molds) or macroscopic (e.g., edible mushrooms) species.

Whereas most fungal species are harmless to humans, a minority can cause cause serious ailments in humans, particularly in patients with compromised immune systems. Such fungal diseases include aspergillosis, blastomycosis, candidiasis, coccidioidomycosis, cryptococcosis, histoplasmosis, mucormycosis, mycetomas, paracoccidioidomycosis, and pneumocystis pneumonia. A set of fungal organisms (dermatophytic and keratinophilic species) have a tropism for human skin, as well as eyes, nails, and hair, being associated with localized infections (e.g., dermatophytosis and tinea pedis). Fungal spores, which are microscopic particles that have key roles in non-sexual fungal reproductions, can be responsible for a number of allergies, most often from the middle of summer to early autumn. Medicinal products that can be used to prevent and conquer fungal infections are urgently needed in modern medicine.

This Special Issue aims to provide a platform to make the results of research regarding molecular mechanistic aspects of fungi available, with a particular focus on research regarding potential treatments and novel signaling pathways relevant to overcoming fungal infections. Papers exploring antifungal development (from both synthetic and natural product starting points), particularly antifungal screening, antifungal biological target identification and validation, repurposing authorized molecules for antifungal purposes, molecular mechanisms involved in efficacy or safety aspects as well as in resistance to current treatments, the physicochemical properties of antifungal compounds, -omics approaches in understanding fungal infection and reproduction, as well as structure–activity relationships, will be considered for publication in this Special Issue.

We warmly welcome submissions of original papers and reviews based on results from molecular viewpoints.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Candida albicans (Ca) is frequently detected in the peri-implant sulcus with peri-implantitis, a major postoperative complication after oral implant therapy. However, the involvement of Ca in the pathogenesis of peri-implantitis remains unclear. In this study, we aimed to clarify Ca prevalence in the peri-implant sulcus and investigated the effects of candidalysin (Clys), a toxin produced by Ca, on human gingival fibroblasts (HGFs). Peri-implant crevicular fluid (PICF) was cultured using CHROMagar and Ca colonization rate and colony numbers were calculated. The levels of interleukin (IL)-1β and soluble IL-6 receptor (sIL-6R) in PICF were quantified by enzyme-linked immunosorbent assay (ELISA). Pro-inflammatory mediator production and intracellular signaling pathway (MAPK) activation in HGFs were measured by ELISA and Western blotting, respectively. The Ca colonization rate and the average number of colonies in the peri-implantitis group tended to be higher than those in the healthy group. IL-1β and sIL-6R levels in the PICF were significantly higher in the peri-implantitis group than in the healthy group. Clys significantly induced IL-6 and pro-matrix metalloproteinase (MMP)-1 productions in HGFs, and co-stimulation with Clys and sIL-6R increased IL-6, pro-MMP-1, and IL-8 production levels in HGFs compared with Clys stimulation alone. These findings suggest that Clys from Ca plays a role in the pathogenesis of peri-implantitis by inducing pro-inflammatory mediators. Full article
