Saps1-3 Antigens in Candida albicans: Differential Modulation Following Exposure to Soluble Proteins, Mammalian Cells, and Infection in Mice. Infect Dis Rep 2024; 16:572-586. [PMID: 39051243 PMCID: PMC11270244 DOI: 10.3390/idr16040043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2024] [Revised: 06/17/2024] [Accepted: 06/25/2024] [Indexed: 07/27/2024] Open
Abstract
The secreted aspartic peptidases (Saps) of Candida albicans play crucial roles in various steps of fungal-host interactions. Using a flow cytometry approach, this study investigated the expression of Saps1-3 antigens after (i) incubation with soluble proteins, (ii) interaction with mammalian cells, and (iii) infection in immunosuppressed BALB/c mice. Supplementation strategies involving increasing concentrations of bovine serum albumin (BSA) added to yeast carbon base (YCB) medium as the sole nitrogenous source revealed a positive and significant correlation between BSA concentration and both the growth rate and the percentage of fluorescent cells (%FC) labeled with anti-Saps1-3 antibodies. Supplementing the YCB medium with various soluble proteins significantly modulated the expression of Saps1-3 antigens in C. albicans. Specifically, immunoglobulin G, gelatin, and total bovine/human sera significantly reduced the %FC, while laminin, human serum albumin, fibrinogen, hemoglobin, and mucin considerably increased the %FC compared to BSA. Furthermore, co-cultivating C. albicans yeasts with either live epithelial or macrophage cells induced the expression of Saps1-3 antigens in 78% (mean fluorescence intensity [MFI] = 152.1) and 82.7% (MFI = 178.2) of the yeast cells, respectively, compared to BSA, which resulted in 29.3% fluorescent cells (MFI = 50.9). Lastly, the yeasts recovered from the kidneys of infected immunosuppressed mice demonstrated a 4.8-fold increase in the production of Saps1-3 antigens (MFI = 246.6) compared to BSA, with 95.5% of yeasts labeled with anti-Saps1-3 antibodies. Altogether, these results demonstrated the positive modulation of Saps' expression in C. albicans by various key host proteinaceous components, as well as by in vitro and in vivo host challenges.

Abstract
Moringa oleifera L., commonly known as Kelor in Indonesia and miracle tree in English, has a rich history of utilization for medicinal, nutritional, and water treatment purposes dating back to ancient times. The plant is renowned for its abundance of vitamins, minerals, and various chemical constituents, making it a valuable resource. Among its notable pharmacological properties are its effectiveness as an anti-diabetic, anti-diarrheal, anti-helmintic, anti-leishmanial, anti-fungal, anti-bacterial, anti-allergic, anti-cancer, anti-inflammatory, and anti-oxidant agent.

Susceptibility to Oral Antiseptics and Virulence Factors Ex Vivo Associated with Candida spp. Isolated from Dental Prostheses. J Prosthodont 2019; 28:398-408. [PMID: 30768738 DOI: 10.1111/jopr.13037] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/03/2019] [Indexed: 12/16/2022] Open
Abstract
PURPOSE To isolate Candida spp. from dental prosthesis users' saliva and to evaluate the isolates for the presence of several virulence factors. This research also aimed to investigate the antifungal activity of 3 commercial mouthwashes/oral antiseptic formulations containing 0.12% chlorhexidine, 0.07% cetylpyridinium, or 0.075% cetylpyridinium against planktonic and sessile (biofilm mode) yeast cells. MATERIALS AND METHODS Forty-three Candida yeasts were isolated from 32 of 70 selected patients, and the virulence factors of C. albicans, C. krusei, C. glabrata, C. tropicalis, and C. parapsilosis species were investigated by polymerase chain reaction (PCR) and proteinase in plates. Minimum inhibitory concentration (MIC), and in vitro biofilm assay evaluated the antifungal activity of antiseptics. RESULTS C. albicans, C. krusei, C. glabrata, C. tropicalis, and C. parapsilosis were detected in mono and mixed cultures. Only C. albicans displayed genes related to adhesion and proteinases (ALS2, ALS3, SAP1, and SAP3). The aspartate proteinase activity was found in 60.46% of isolates. The tested antiseptic formulations exhibited a MIC less than 1.25% toward yeasts in the planktonic mode. According to XTT ((2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide) assay results, most Candida isolates and all mixed cultures formed biofilms within 24 hours. The evaluated antiseptic formulations were also active against biofilms. CONCLUSION Most virulence factors investigated here (ALS2, ALS3, SAP1, and SAP3) occurred in the majority of the Candida spp. isolates, especially in C. albicans. The tested mouthwash formulations were effective against all the yeast isolates in both the planktonic and sessile growth modes. Developing alternative therapies that can avoid or control biofilm formation is necessary to prevent oral candidiasis and other Candida spp. infections.

Antimicrobial activity of Psidium cattleianum associated with calcium hydroxide against Enterococcus faecalis and Candida albicans: an in vitro study. Clin Oral Investig 2018; 22:2273-2279. [PMID: 29318387 DOI: 10.1007/s00784-017-2326-5] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2017] [Accepted: 12/21/2017] [Indexed: 11/28/2022]
Abstract
OBJECTIVE Evaluate, in vitro, the antimicrobial activity of Psidium cattleianum leaf extracts combined with calcium hydroxide against Enterococcus faecalis and Candida albicans biofilm. MATERIALS AND METHODS Dentin specimens obtained from extracted bovine incisors were infected during 14 days with E. faecalis ATCC 29212 and C. albicans ATCC 10231. The specimens were filled with calcium hydroxide pastes prepared with the following vehicles: Psidium cattleianum ethanolic, Psidium cattleianum propylene glycolic, distilled water, and saline as control. After 24 h, 3, 7, and 14 days, the canals were irrigated with sterile saline and dried. Dentin samples were collected from the canals with burs of increasing diameters. To determine the number of colony-forming units (CFU), samples were inoculated onto BHI agar supplemented with yeast extract (0.5%), at 37 °C, for 48 h, in CO2 enriched atmosphere. Comparisons among the groups for the variation factors were performed by ANOVA and Tukey's test. RESULTS Ethanolic and propylene glycolic extracts showed significantly higher antimicrobial activity against E. faecalis (p < 0.01) when compared with distilled water. The ethanolic extract exhibited in 24 h the same antibacterial activity that propylene glycolic extract and distilled water after 7 and 14 days. For C. albicans, all were effective in reducing the number of CFU at all periods. CONCLUSION The P. cattleianum ethanolic extract presented the fastest and highest antimicrobial activity against E. faecalis, significantly reducing the microbial load in 24 h. All medications were effective against C. albicans. CLINICAL RELEVANCE The antibacterial potential of P. cattleianum and its biological compatibility associated with calcium hydroxide indicate promising applications in the field of dentistry.
