Human T lymphocyte cell line producing colony-stimulating activity.
We derived a permanent human T lymphocyte cell line that elaborates a potent colony-stimulating activity (CSA). The line was established with spleen cells from a patient with a T lymphocyte variant of hairy-cell leukemia. These cells form rosettes with sheep erythrocytes, show a proliferative response to phytohemagglutinin, and are lysed by antithymocyte globulin. They do not synthesize immunog...
متن کاملThe production of granulocyte-monocyte colony-stimulating activity by isolated human T lymphocyte subpopulations.
Isolated human T lymphocyte subpopulations were obtained by fluorescence-activated cell sorting using the murine monoclonal antibodies, OKT4 and OKT8. The capabilities of the isolated lymphocytes to produce granulocyte-monocyte colony-stimulating activity (CSA) in response to mitogen challenge were assessed by in vitro assays employing light density nonadherent bone marrow cells. Essentially, n...
متن کاملAcute myelogenous leukemia: a human cell line responsive to colony-stimulating activity.
A permanent human cell line that maintains the granulocytic characteristics of acute myelogenous leukemia cells has been established. The cells of this line form myeloid colonies in soft gel culture in the presence of human colony-stimulating activity. The cell line may be useful for studying human acute myelogenous leukemia and the mechanism of response to colony-stimulating activity.
متن کاملT lymphocyte and monocyte-macrophage interaction in colony-stimulating activity elaboration in man.
Using in vitro culture systems. we have studied the effect of coincubating human monocyte-macrophages with autologous T lymphocytes on colony-stimulating activity (CSA) elaboration in response to methanol extraction residue (MER) of BCG. When monocyte-macrophages were coincubated with T lymphocytes for 4 days at a ratio of 1 :3. the resultant colony-stimulating activity. assayed against light d...
متن کاملPurification and characterization of a human T-lymphocyte-derived granulocyte-macrophage colony-stimulating factor.
We have examined the biologic and physical properties of a human T-lymphocyte granulocyte-macrophage colony-stimulating factor (CSF). The source of the factor is a T-lymphoblast cell line (Mo) that was derived from a patient with a T-cell variant of hairy-cell leukemia. The Mo line constitutively produces a number of lymphokines that are normally produced by mitogen-stimulated T lymphocytes. Me...
