Target cells for interferon production in human leukocytes stimulated by sendai virus. 1977

T Yamaguchi, and K Handa, and Y Shimizu, and T Abo, and K Kumagai

Whole leukocytes, mononuclear cells, polymorphonuclear cells (PMN), MONOCYTES, PURIFIED LYMPHOCYTES, AND T (rosette-forming cells, RFC) and non-T (nonrosette-forming cells, nonRFC) lymphocytes isolated from the human peripheral blood were stimulated by Sendai virus, respectively, and examined for interferon production in their culture fluids. High levels of interferon were produced by mononuclear cells, but not by PMN. Removal of monocytes from the mononuclear cell population did not affect at all the levels of interferon produced, although it strongly suppressed interferon induction by polyinosinic-polycytidylic acid (poly IC) and mitogenic response to phytohemagglutinin (PHA) of the lymphocytes. Purified monocytes and T lymphocytes were unresponsive to the virus. In contrast, a population of purified non-T lymphocytes produced high levels of interferon. Addition of monocytes to the interferon-producing non-T lymphocytes did not affect the levels of interferon produced. No detectable levels of interferon were produced in the mixture of T lymphocytes and monocytes. It is concluded that non-T lymphocytes may be a major target for interferon induction of human leukocytes by Sendai virus.

D007372	Interferons	Proteins secreted by vertebrate cells in response to a wide variety of inducers. They confer resistance against many different viruses, inhibit proliferation of normal and malignant cells, impede multiplication of intracellular parasites, enhance macrophage and granulocyte phagocytosis, augment natural killer cell activity, and show several other immunomodulatory functions.	Interferon
D007962	Leukocytes	White blood cells. These include granular leukocytes (BASOPHILS; EOSINOPHILS; and NEUTROPHILS) as well as non-granular leukocytes (LYMPHOCYTES and MONOCYTES).

D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell

D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
