Transfer factor: a subcellular component that transmits information for specific immune responses.

S Rosenfeld, D Dressler

    Proceedings of the National Academy of Sciences of the United States of America
    |June 1, 1974
    PubMed
    Summary

    Researchers developed two transfer factors from guinea pig leukocytes. These small molecules transfer specific immune response information to naive individuals, enhancing immunity.

    Area of Science:

    • Immunology
    • Molecular Biology

    Background:

    • Immune responses are complex and involve cell-to-cell communication.
    • Transfer factors are hypothesized to mediate the transfer of specific immunity.

    Purpose of the Study:

    • To prepare and characterize transfer factors in an animal model.
    • To assess the ability of these factors to transfer specific immune information.

    Main Methods:

    • Preparation of transfer factors from guinea pig leukocytes.
    • Administration of transfer factors to naive guinea pigs.

    Main Results:

    • Two distinct transfer factors were successfully prepared.
    • These factors are small molecules derived from immune cells.
    • The transfer factors conveyed specific immune response information.

    Conclusions:

    • Transfer factors can be prepared from leukocyte-derived small molecules.
    • These factors effectively transfer specific immunity in a guinea pig model.
