Molecular alterations of interferons.

W E Stewart, L Lin, T Chudzio

    Texas Reports on Biology and Medicine
    |January 1, 1977
    PubMed
    Summary

    Chemically or enzymatically altering interferons yields smaller, more stable forms with broader host-range. These modified interferons may overcome native interferon limitations like species-specificity.

    Area of Science:

    • Biochemistry
    • Immunology
    • Molecular Biology

    Background:

    • Interferons (IFNs) are crucial antiviral proteins.
    • Native interferons exhibit species-specificity and variable stability.
    • Modifications can alter IFN properties.

    Purpose of the Study:

    • To investigate chemical and enzymatic alterations of interferons.
    • To obtain modified interferon forms with potentially improved characteristics.
    • To assess changes in size, charge, and host-range.

    Main Methods:

    • Chemical modification of interferons.
    • Enzymatic treatment of interferons.
    • Analysis of physical (size, charge) and biological (activity, host-range) markers.

    Main Results:

    • Altered molecular forms of interferons were obtained.
    • These forms differed in size, charge, and/or host-range from native interferons.
    • Small active cores with potentially desirable characteristics were identified.

    Conclusions:

    • Interferon modification can yield forms with enhanced stability and broader host-range.
    • Modified interferons may overcome native interferon limitations like species-specificity.
    • Characterization of modified interferons requires monitoring of activities and physical/biological markers.
