Lectin histochemistry applied to human nerves.

R Estruch, I Damjanov

    Archives of Pathology & Laboratory Medicine
    |August 1, 1986
    PubMed
    Summary

    Lectin histochemistry can identify peripheral nerve injury by observing how specific plant lectins bind to nerve tissues. While some lectins bind to all nerves, two lectins specifically bind to damaged nerves, aiding in pathology studies.

    Area of Science:

    • Neuroscience
    • Biochemistry
    • Histology

    Background:

    • Peripheral nerve injury diagnosis relies on various methods.
    • Histochemical staining offers potential for identifying tissue alterations.
    • Lectins are proteins that bind to carbohydrates and can be used as biological stains.

    Purpose of the Study:

    • To evaluate the utility of fluorescein isothiocyanate-labeled lectins in identifying human peripheral nerve injury.
    • To establish baseline lectin binding patterns in normal and pathologically altered peripheral nerves.

    Main Methods:

    • Histologic sections of human peripheral nerves (normal and pathologically altered) were stained with 20 different fluorescein isothiocyanate-labeled lectins.
    • Binding patterns of each lectin were analyzed to identify selective interactions with nerve tissues.

    Main Results:

    • Eight plant lectins showed binding to both normal and pathologically altered nerves.
    • Two lectins, from Helix pomatia and Maclura pomifera, demonstrated selective binding to pathologically altered nerves.
    • Observed lectin binding changes were not specific to any particular type of nerve injury.

    Conclusions:

    • Lectin histochemistry can differentiate between normal and pathologically altered peripheral nerves.
    • Specific lectins show promise for studying peripheral nerve pathology.
    • Further research is needed to determine the diagnostic specificity of these lectin binding patterns.
