Abstract

Candida albicans escapes from the bloodstream by invading the endothelial cell lining of the vasculature. In vitro, C. albicans invades endothelial cells by inducing its own endocytosis. We examined whether this process is regulated by the tyrosine phosphorylation of endothelial cell proteins. We found that endocytosis of wild-type C. albicans was accompanied by the tyrosine phosphorylation of two endothelial cell proteins with molecular masses of 80 and 82 kDa. The phosphorylation of these proteins was closely associated with the endocytosis of C. albicans because these proteins were phosphorylated in response to the endocytosis of both live and killed organisms, but they were not phosphorylated in endothelial cells infected with a poorly endocytosed strain of C. albicans. The tyrosine kinase inhibitors genistein and tyrphostin 47 blocked the phosphorylation of the two endothelial cell proteins and significantly reduced endocytosis of C. albicans. Therefore, C. albicans probably induces its own endocytosis by stimulating the tyrosine phosphorylation of two endothelial cell proteins.

  • Endothelial cell endocytosis of C. albicans is dependent on extracellular calcium and is governed at least in part by the tyrosine phosphorylation of endothelial cell proteins.

    “Endothelial cell endocytosis of C. albicans is dependent on extracellular calcium and is governed at least in part by the tyrosine phosphorylation of endothelial cell proteins [9,11].”

    From Als3 Is a Candida albicans Invasin That Binds to Cadherins and Induces Endocytosis by Host Cells (2007) · cites this paper as [11]

    The Discussion reports that tyrosine kinase inhibitors reduced endothelial uptake of C. albicans and concludes that phosphorylation of at least one endothelial protein is likely required for endocytosis. That supports the claim’s qualified phosphorylation component. Neither the supplied passages nor searches for extracellular calcium and related terms establish that endocytosis depends on extracellular calcium. (LLM, conf=0.88)

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.
