The fungal pathogen Candida albicans has a multilayered cell wall composed of an outer layer of proteins glycosylated with N- or O-linked mannosyl residues and an inner skeletal layer of beta-glucans and chitin. We demonstrate that cytokine production by human mononuclear cells or murine macrophages was markedly reduced when stimulated by C. albicans(More)
The green fluorescent protein (GFP) of Aequorea victoria has been developed here as a reporter for gene expression and protein localization in Candida albicans. When wild-type (wt) GFP was expressed in C. albicans, it was not possible to detect fluorescence or a translation product for the wt protein. Since this was probably due in part to the presence of(More)
The pathogen Candida albicans responds to amino acid starvation by activating pseudohyphal development and the expression of amino acid biosynthetic genes (GCN response). In Saccharomyces cerevisiae, the GCN response is dependent on Gcn2, which regulates the translation of the transcription factor Gcn4. Therefore, we examined the role of Gcn2 in C. albicans(More)
Global analysis of the molecular responses of microbial pathogens to their mammalian hosts represents a major challenge. To date few microarray studies have been performed on Candida albicans cells derived from infected tissues. In this study we examined the C. albicans SC5314 transcriptome from renal infections in the rabbit. Genes involved in adhesion,(More)
Candida albicans HSP90 sequences were isolated by screening cDNA and genomic libraries with a probe derived from the Saccharomyces cerevisiae homolog, HSP82, which encodes a member of the heat shock protein 90 family of molecular chaperones. Identical sequences were obtained for the 2,197-bp overlap of the cDNA and gene sequences, which were derived from C.(More)
A cDNA library was made with mRNA from Candida albicans grown under conditions favoring the hyphal form. The library was screened for sequences that encode immunogenic proteins by using pooled sera from five patients with oral candidiasis and five uninfected patients. Most of these patients were human immunodeficiency virus positive. From 40,000 cDNA clones(More)
The imperfect fungus, Candida albicans is the major yeast pathogen in humans (1). We have analysed the codon usage in eleven C. albicans gene sequences reported in the EMBL and GenBank databases (Table). The codons are divided into three groups (low, medium and high) based upon their codon usage (Table), and these groups are compared with analogous groups(More)
The intracellular distribution of potassium in Malpighian tubules from Drosophila larva was measured by electron probe X-ray microanalysis of freeze-dried cryosections. Application of amiloride alone to the haemolymph space had no effect on the intracellular potassium concentration in the region of intermediate cytoplasm (between the basal region of basal(More)
