Candida albicans specializations for iron homeostasis: from commensalism to virulence

Open access
Noble, Suzanne M·2013·Current Opinion in Microbiology

Abstract

Candida albicans is a fungal commensal-pathogen that persistently associates with its mammalian hosts. Between the commensal and pathogenic lifestyles, this microorganism inhabits host niches that differ markedly in the levels of bioavailable iron. A number of recent studies have exposed C. albicans specializations for acquiring iron from specific host molecules in regions where iron is scarce, while also defending against iron-related toxicity in regions where iron occurs in surfeit. Together, these results point to a central role for iron homeostasis in the evolution of this important human pathogen.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Elevated concentrations of hepcidin increase iron sequestration by macrophages and decrease duodenal iron absorption during inflammatory reactions, thus reducing plasma iron levels.

    “Elevated concentrations of hepcidin increase iron sequestration by macrophages and decrease duodenal iron absorption during inflammatory reactions and thus reduces plasma iron levels (Cassat and Skaar, 2013; Noble, 2013).”

    From Iron at the Centre of Candida albicans Interactions (2018) · cites this paper as Noble, 2013

    In “Mechanisms of iron acquisition in the bloodstream” (page unavailable), Noble says inflammatory responses reduce serum iron through decreased intestinal absorption and retention within reticuloendothelial cells. The passage does not identify elevated hepcidin as the cause or specify duodenal absorption and macrophages. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Iron ions regulate hyphal development and morphological transitions by modulating key transcription factors, including Sef1, Hap43, and Sfu1.

    “They regulate hyphal development and morphological transitions by modulating key transcription factors, including Sef1, Hap43, and Sfu1 (Noble 2013; Singh et al. 2011).”

    From Aloe emodin disrupts Candida albicans mitochondrial iron homeostasis against its hyphal development and oral candidiasis (2026) · cites this paper as Noble 2013

    The section ‘Defense against iron excess in the gut’ describes iron-dependent regulation involving Sef1, Hap43, and Sfu1. But ‘From iron homeostasis to developmental switches’ says further experiments are needed to determine whether iron levels trigger the developmental transition; it does not establish that these factors regulate hyphal development. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • C. albicans has evolved a complex regulatory program for iron uptake that operates in both commensal and pathogenic states.

    “Thus, C. albicans has evolved an intricate transcriptional program to regulate iron acquisition during commensal or pathogenic states [91].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
