[Interferon-specific cellular receptors in cultured human cells, differing in sensitivity to alpha-interferon]
Summary
Human cells resistant to alpha-interferon lack specific cell receptors, preventing effective interferon-receptor interaction. This receptor absence explains interferon resistance in certain cell lines.
Area of Science:
- Immunology
- Cell Biology
- Molecular Biology
Context:
- Investigating the role of cell surface receptors in cellular responses to interferons.
- Examining human cell cultures with varying sensitivities to alpha-interferon.
Purpose:
- To study interferon-specific cellular receptors in human cell cultures.
- To determine the correlation between receptor presence and alpha-interferon sensitivity.
Summary:
- Alpha-interferon resistant J-41 cells exhibit a near-complete absence of specific alpha-interferon receptors.
- Sensitive J-96 cells show a high affinity for interferon receptors (Kd = 15.6 x 10^11 M^-1) with approximately 210 receptors per cell.
- The lack of interferon receptors in J-41 cells is directly linked to their resistance to alpha-interferon, inhibiting cellular interaction.
Impact:
- Provides a molecular basis for understanding alpha-interferon resistance in human cells.
- Highlights the critical role of specific cell surface receptors in mediating interferon signaling pathways.
- Offers potential targets for therapeutic strategies aimed at overcoming interferon resistance.
