    Immuno-electron microscopy revealed that the Fc fragment of IgG on red blood cells (erythrocytes) binds to receptors on lymphoid cells. This binding occurs precisely at the contact points observed in human EA rosettes.

    Area of Science:

    • Immunology
    • Cell Biology
    • Microscopy

    Background:

    • Human EA rosettes involve interactions between erythrocytes and lymphoid cells.
    • The precise molecular interactions at these contact sites require detailed investigation.

    Purpose of the Study:

    • To elucidate the molecular basis of cell-cell adhesion in human EA rosettes.
    • To identify the specific binding sites between erythrocytes and lymphoid cells.

    Main Methods:

    • Immuno-electron microscopy was employed.
    • Ferritin-labelled anti-human IgG antiserum was used for visualization.

    Main Results:

    • Clusters of ferritin granules were observed at the contact points between erythrocytes and lymphoid cells.

  • These findings indicate specific binding sites between the cells.

    • Conclusions:

    • The Fc fragment of IgG on erythrocytes interacts with specific receptors on lymphoid cells.
    • These molecular interactions directly correspond to the observed morphological contact sites in EA rosettes.
