Abstract

The proteome of Aggregatibacter actinomycetemcomitans HK1651 (JP2 clone) and immunoreactive antigens were studied by two-dimensional (2D) gel electrophoresis, matrix-assisted laser desorption time-of-flight mass spectrometry (MALDI-TOF-MS), and 2D immunoblotting. The highly leukotoxic JP2 clone of A. actinomycetemcomitans is strongly associated with aggressive periodontitis (AgP) in adolescents of North-West African descent and the pathogenicity of this bacterium is of major interest. Hence, we developed a comprehensive 2D proteome reference map of A. actinomycetemcomitans proteins with 167 identified spots representing 114 different proteins of which 15 were outer membrane proteins. To unravel immunoreactive antigens, we applied 2D-gel and subsequent immunoblotting analyses using sera from five individuals with A. actinomycetemcomitans infections and one healthy control. The analysis revealed 32 immunoreactive proteins. Antibodies to two outer membrane proteins, YaeT (85 kDa) and Omp39 (39 kDa), not previously described as immunoreactive, were found only in subjects with current or previous A. actinomycetemcomitans JP2 infection. Further proteome-based studies of A. actinomycetemcomitans combined with analyses of the humoral immune response and targeted against outer membrane proteins may provide important insight into the host relationship of this important pathogen.

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.
