Cell-surface carbohydrates in cell recognition and response.

B K Brandley, R L Schnaar

    Journal of Leukocyte Biology
    |July 1, 1986
    PubMed
    Summary

    Cell surface carbohydrates and sugar-binding proteins (lectins) mediate cell-cell recognition and adhesion. Understanding this carbohydrate "language" is key to deciphering complex intercellular interactions.

    Area of Science:

    • Glycoscience
    • Cell Biology
    • Biochemistry

    Background:

    • Complex carbohydrates on cell surfaces act as information carriers.
    • Cell-surface receptors, known as lectins, bind to these carbohydrates.
    • This interaction facilitates cell-cell adhesion, crucial for biological processes.

    Purpose of the Study:

    • To investigate the role of carbohydrate-lectin interactions in cell adhesion.
    • To elucidate the mechanisms underlying carbohydrate-mediated intercellular communication.

    Main Methods:

    • Synthesis of chemically defined cell-surface analogs.
    • Conducting inhibition experiments to study adhesion mechanisms.

    Main Results:

    • Demonstrated that carbohydrate-lectin interactions are fundamental to cell adhesion.
    • Provided insights into the mechanics of carbohydrate-directed cell recognition.

    Conclusions:

    • Carbohydrate-lectin interactions form a sophisticated 'language' for intercellular communication.
    • This understanding has implications for various biological processes, including infection and immune response.
