[T lymphocytes with chimeric receptor induce carcinoembryonic antigen-positive specific gastric carcinoma cells apoptosis].

Objective: To develop a method to generate T lymphocytes that identify tumor specific carcinoembryonic antigen (CEA), and induce anti-tumor response such as apoptosis.

Methods: Peripheral blood samples were collected from 10 healthy persons and peripheral blood mononuclear cells (PBMCs) were isolated. 1, then CD8(+) T cells were isolated from the PBMCs by magnetic activated cell sorting (MACS) using magnetic beads-conjugated anti-CD8 monoclonal antibodies.
