Previous evaluation of HWP1 in systemic candidiasis in CBA/J mice was done with Candida albicans strains with differing genetic locations of URA3 as a result of Ura-blaster mutagenesis. In this study, the presence of HWP1 and the location of URA3 contributed to the severity of murine systemic candidiasis in BALB/c mice.
BACKGROUND AND PURPOSE Hyphal wall protein 1 (HWP1) is an important adhesin which usually is expressed on the germ tube and hyphal surface produced by different Candida species. The hyphal wall protein-coding gene (HWP1) was evaluated as a novel identification and phylogenetic marker in Candida tropicalis, C. orthopsilosis, C. parapsilosis and C. glabrata. MATERIALS AND METHODS Initially, four...
Candida albicans is an opportunistic fungal pathogen found as mycoflora in the human body surfaces. Sevral genes play a crucial rule in its virulence including Hwp1 (hyphal wall protein 1), BCR1 and ALS gene family. Hwp1 gene is a responsible for coding a cell surface protein, which mediates biofilm formation in candida albicans. Here we investigated the presence of the HWP1gene was characteris...
Coeliac disease is a T-cell-mediated autoimmune disease of the small intestine that is induced by ingestion of gluten proteins from wheat, barley, or rye. We postulate that Candida albicans is a trigger in the onset of coeliac disease. The virulence factor of C albicans-hyphal wall protein 1 (HWP1)-contains aminoacid sequences that are identical or highly homologous to known coeliac disease-rel...
OBJECTIVES Systemic candidal infections are a common problem in hospitalized patients due to central venous catheters fabricated using silicone biomaterial (SB). We therefore evaluated the effect of human serum on C. albicans biofilm morphology, growth, and the expression of virulence-related genes on SB in vitro. METHODS We cultivated C. albicans SC5314 (wild-type strain, WT) and its derivat...
Proteins that are covalently linked to the skeletal polysaccharides of the cell wall of Candida albicans play a major role in the colonization of the vaginal mucosal surface, which may result in vaginitis. Here we report on the variability of the cell-wall proteome of C. albicans as a function of the ambient O(2) concentration and iron availability. For these studies, cells were cultured at 37 ...

هدف: تقریباً سه چهارم زنان در معرض واژینیت کاندیدیایی هستند. از جمله عوامل بیماریزا می توان به قدرت اتصال کاندیدا به بافت میزبان از طریق عواملی مانند مولکول های چسبنده و پروتئین هایی که این اتصال را تسریع میکنند اشاره نمود. هدف از انجام مطالعه حاضر؛ بررسی فراوانی ژن های مولد بیوفیلم در سویه های کاندیدا آﻟﺒﯿﮑﻨﺲ جداشده از واژینوز (Vaginosis) و بررسی مقایسه ای بیان ژن als در...
Filamentous growth is an important virulence trait of the human pathogenic fungi within the genus Candida, and the greater propensity of C. albicans to form hyphae has been proposed to account for the greater virulence of this species relative to the less pathogenic species C. dubliniensis. In this meta-analysis, we compare the transcriptional response of C. dubliniensis and C. albicans to the ...
Candida albicans triggers recurrent infections of the oropharyngeal mucosa that result from biofilm growth. Prior studies have indicated that the transcription factor Bcr1 regulates biofilm formation in a catheter model, both in vitro and in vivo. We thus hypothesized that Bcr1 plays similar roles in the formation of oral mucosal biofilms and tested this hypothesis in a mouse model of oral infe...
