Abstract

Human pulmonary and subcutaneous dirofilariosis caused by Dirofilaria immitis and Dirofilaria repens are worldwide diagnosed with increasing frequency. These species are responsible for the development of benign pulmonary and subcutaneous nodules, respectively, that can be confused with lung or cutaneous cancer. The aim of the present work was to identify D. immitis and D. repens proteins differentially recognized by serum samples from individuals with human pulmonary and subcutaneous dirofilariosis, using two-dimensional electrophoresis and mass spectrometry. Twenty-three immunoreactive proteins of D. immitis and 15 of D. repens were identified. The results point to the existence of differential antigenic recognition in each species, both in the number and type of proteins recognized. Individuals with pulmonary dirofilariosis recognized, on the proteome of D. immitis, among others, different isoforms of 6 enzymes involved in glycolysis, 3 redox-related proteins with antioxidant capacity and 3 heat shock proteins. Individuals with subcutaneous dirofilariosis recognized on the proteome of D. repens only 3 glycolytic enzymes, one protein involved in redox processes and one heat shock protein. These data suggest that in cases of pulmonary dirofilariosis there exists a wider recognition of immunoreactive D. immitis proteins related to key survival processes, such as energy generation, the struggle against oxidative stress and molecular repair, than in cases of human subcutaneous dirofilariosis against D. repens. This could contribute to explain the differences described in the capacity of D. immitis and D. repens development and in the frequency of occurrence of pulmonary and subcutaneous dirofilariosis in the human host.

Claims other papers make about this one

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

  • Proteomics with mass spectrometry allowed the simultaneous identification of numerous proteins, comprising 39 proteins from D. immitis and 15 from D. repens, many represented by several isoforms.

    “Together with mass spectrometry, proteomics allowed the simultaneous identification of numerous proteins, comprising 39 proteins from D. immitis and 15 from D. repens, many of which were represented by several isoforms (157,158,313).”
  • A recent analysis of D. immitis and D. repens proteomes and immunomes showed that D. immitis stimulates more vigorous antibody production against its energy metabolism and detoxification machinery than D. repens.

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.
