Carbohydrates act as receptors for the periodontitis-associated bacterium Porphyromonas gingivalis: A study of bacterial binding to glycolipids

Hellstrom, U.·2004·Glycobiology

Abstract

In this study we show for the first time the use of carbohydrate chains on glycolipids as receptors for the periodontitis-associated bacterium Porphyromonas gingivalis. Previous studies have shown that this bacterium has the ability to adhere to and invade the epithelial lining of the dental pocket. Which receptor(s) the adhesin of P. gingivalis exploit in the adhesion to epithelial cells has not been shown. Therefore, the binding preferences of this specific bacterium to structures of carbohydrate origin from more than 120 different acid and nonacid glycolipid fractions were studied. The bacteria were labeled externally with (35)S and used in a chromatogram binding assay. To enable detection of carbohydrate receptor structures for P. gingivalis, the bacterium was exposed to a large number of purified total glycolipid fractions from a variety of organs from different species and different histo-blood groups. P. gingivalis showed a preference for fractions of human and pig origin for adhesion. Both nonacid and acid glycolipids were used by the bacterium, and a preference for shorter sugar chains was noticed. Bacterial binding to human acid glycolipid fractions was mainly obtained in the region of the chromatograms where sulfated carbohydrate chains usually are found. However, the binding pattern to nonacid glycolipid fractions suggests a core chain of lactose bound to the ceramide part as a tentative receptor structure. The carbohydrate binding of the bacterium might act as a first step in the bacterial invasion process of the dental pocket epithelium, subsequently leading to damage to periodontal tissue and tooth loss.

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.
