The human interleukin-2 receptor: analysis of structure and function.

W C Greene, J M Depper, M Krönke

    Immunological Reviews
    |August 1, 1986
    PubMed
    Summary

    Researchers have identified the human Interleukin-2 (IL-2) receptor protein, gene, and mRNAs, crucial for T-cell growth. Future therapies may target this receptor to modulate immune responses, though key questions about its structure and signaling remain.

    Area of Science:

    • Immunology
    • Molecular Biology
    • Cell Biology

    Background:

    • The human Interleukin-2 (IL-2) receptor's molecular, biochemical, and biological characteristics are extensively documented.
    • Identification of the IL-2 receptor protein, multiple receptor mRNAs, and a single structural gene has been achieved.
    • The IL-2 receptor's established role in normal T-cell proliferation and its potential involvement in B-cell functions are recognized.

    Purpose of the Study:

    • To review the current understanding of the human IL-2 receptor.
    • To highlight the potential for novel therapeutic agents based on IL-2 receptor and IL-2 gene products.
    • To underscore the ongoing research into the IL-2 receptor's role in immune responses and viral infections.

    Main Methods:

    • Literature review of existing data on IL-2 receptor.

    Related Experiment Videos

  • Analysis of identified IL-2 receptor protein, mRNAs, and gene structure.
  • Exploration of the relationship between HTLV-I/II infections and IL-2 receptor expression.

    • Main Results:

    • The IL-2 receptor protein, multiple mRNAs, and a single structural gene have been identified.
    • The IL-2 receptor's critical role in T-cell growth is well-established.
    • Potential for IL-2 receptor and IL-2 gene products in developing immunomodulatory agents.

    Conclusions:

    • The IL-2 receptor is a key target for modulating T-cell immunity.
    • Further research is needed to understand the structural differences between high and low affinity receptors.
    • Unraveling the signal transduction mechanisms of the high-affinity IL-2 receptor is a critical future direction.
