Stable transfection of reticuloendotheliosis virus-transformed lymphoblastoid cell lines.
Lymphoblastoid T cell lines were established by infection of chicken splenocytes with reticuloendotheliosis virus (REV). The target cells first were cultured in interleukin-containing conditioned medium or were stimulated by concanavalin A, or both. Most cell lines were T cells expressing CD3 and one of the T cell receptors, and all cell lines were positive for major histocompatibility complex (MHC) class II antigens. Several REV-transformed cell lines were stably transfected using electroporation with a selectable plasmid, pNL1, containing the neor gene. Transfected cell lines were selected using G418 and were maintained for periods up to 137 days. Transfected cell lines were susceptible to MHC class-I restricted lysis by cytotoxic T lymphocytes from REV-infected chickens.
