Abstract

Viral transformation of T cells is an effective method for obtaining large numbers of T cells that are easily maintained in the laboratory. Human T cell leukemia/lymphoma virus (HTLV‐I), a type C retrovirus clearly implicated as the etiologic agent of adult T cell leukemia, can both infect and transform normal T cells. This unit presents a protocol in which human T cells are activated and then transformed with HTLV‐I. Detection of virally transformed cells is discussed in the commentary.

Materials

Basic Protocol 1:

  Materials
  • Cord blood cells, peripheral blood mononuclear cells (PBMC; unit 7.1), or T cell clones (unit 7.19)
  • Complete RPMI‐10 medium ( appendix 2A) without and with 10 to 100 U/ml IL‐2
  • Phytohemagglutinin (PHA; e.g., Burroughs Wellcome or Difco) or specific antigen
  • HTLV‐I‐transforming cell line (ATCC #HUT‐102)
  • Sorvall RT‐6000 centrifuge with H‐1000B rotor (or equivalent)
  • 24‐well flat‐bottom microtiter plate (Costar)
  • 137Cs irradiator (e.g., Gammacell 1000, Nordion)
  • Additional reagents and solutions for Ficoll‐Hypaque gradient centrifugation (unit 7.1) and counting cells ( appendix 3A)
