Histiocyte X positivity for nonspecific esterase.

F Jaubert, S Barbey, C Nogues

    The Journal of Histochemistry and Cytochemistry : Official Journal of the Histochemistry Society
    |January 1, 1980
    PubMed
    Summary

    Histiocytes X in eosinophilic granuloma exhibit cell membrane exoenzymes like other histiocytes. However, the function of X bodies in enzyme activity remains undetermined.

    Area of Science:

    • Cell Biology
    • Histopathology
    • Enzymology

    Background:

    • Eosinophilic granuloma is a histiocytic disorder.
    • Histiocytes X are the characteristic cells in this condition.
    • The enzymatic activity of histiocytes X is not fully understood.

    Purpose of the Study:

    • To investigate the enzyme activity of histiocytes X.
    • To characterize the cell membrane and X bodies of histiocytes X.
    • To compare enzyme activity with other histiocyte types.

    Main Methods:

    • Staining of cell membrane and X bodies of histiocytes X.
    • Utilized nonspecific esterase staining technique.
    • Examined samples from two eosinophilic granuloma cases.

    Main Results:

    • Histiocytes X possess a cell membrane exoenzyme.
    • The observed exoenzyme is similar to that found in other histiocytes, like alveolar macrophages.
    • The specific role of X bodies concerning enzyme activity was not elucidated.

    Conclusions:

    • Histiocytes X share cell membrane enzyme characteristics with other histiocytes.
    • Further research is needed to determine the function of X bodies in enzyme activity.
