Activated T lymphocytes within human solid tumors

摘要: The majority of lymphocytes separated from tumor cell suspensions were T cells. Conjugates and cells often seen. Variable numbers exhibited signs activation such as the ability to form stable E rosettes attachment normal malignant (a phenomenon designated natural attachment: NA). A proportion activated in vitro by allogeneic stimulation regularly exhibit these properties. cell-tumor conjugates may represent NA phenomenon, but they could also be product that adhere on basis specific recognition surface antigens.
