Epstein-barr virus-negative human malignant T-cell lines.

J Kaplan, T C Shope, W D Peterson

    The Journal of Experimental Medicine
    |May 1, 1974
    PubMed
    Summary

    Two malignant lymphoblastoid cell lines, CCRF-CEM and HSB-2, derived from childhood leukemia, exhibit T-cell properties. These cell lines lack Epstein-Barr virus antigens, offering insights into leukemia research.

    Area of Science:

    • Immunology
    • Oncology
    • Cell Biology

    Background:

    • Childhood leukemia can arise secondary to lymphosarcoma.
    • Lymphoblastoid cell lines are crucial tools in cancer research.
    • T-cell properties are characteristic of certain lymphoid malignancies.

    Purpose of the Study:

    • To characterize two specific lymphoblastoid cell lines (CCRF-CEM and HSB-2).
    • To investigate the malignant cell properties of these cell lines.
    • To determine the presence or absence of Epstein-Barr virus (EBV) antigens.

    Main Methods:

    • Cell line characterization.
    • Analysis of cell surface markers for T-cell properties.
    • Testing for Epstein-Barr virus antigens.

    Main Results:

    • CCRF-CEM and HSB-2 cell lines possess properties of malignant cells.
    • Both cell lines exhibit T-cell characteristics.
    • Epstein-Barr virus antigens were not detected in either cell line.

    Conclusions:

    • The CCRF-CEM and HSB-2 cell lines are valuable models for studying T-cell leukemia.
    • The absence of EBV antigens in these lines distinguishes them from EBV-associated lymphoproliferative disorders.
    • Further research can utilize these cell lines to understand leukemia pathogenesis.
