Sendai virus glycoproteins are T cell-dependent B cell mitogens. 1983

S Kizaka, and G Goodman-Snitkoff, and J J McSharry

UV-inactivated Sendai virus is mitogenic for murine splenocytes, whereas infectious Sendai virus kills spleen cells in vitro. The isolated hemagglutinin-neuraminidase (HN) and fusion (F) glycoproteins of Sendai virus are also mitogenic for cultured mouse spleen cells. A mixture of these glycoproteins (1 microgram/well) gives maximum stimulation 96 h after culture initiation. Viral proteins remaining insoluble after Triton X-100 extraction are also mitogenic for mouse spleen cells, with maximum stimulation occurring at 72 h after culture initiation with 1 to 5 microgram/well. On the basis of protein concentration, the HN and F glycoproteins are approximately three times more mitogenic than the Triton X-100-insoluble material. The mitogenic response of the HN and F glycoproteins has two components, a T cell-independent B cell proliferation, which is less than one-half of the total stimulation observed, and a T cell-dependent B cell proliferation. In contrast, the Triton X-100-insoluble material is a T cell-dependent B cell mitogen. Purified T lymphocytes do not respond to the mitogenic signal of either HN-F or Triton X-100-insoluble material.

D008211	Lymphocyte Cooperation	T-cell enhancement of the B-cell response to thymic-dependent antigens.	Cooperation, Lymphocyte,Cooperations, Lymphocyte,Lymphocyte Cooperations
D008213	Lymphocyte Activation	Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D008934	Mitogens	Substances that stimulate mitosis and lymphocyte transformation. They include not only substances associated with LECTINS, but also substances from streptococci (associated with streptolysin S) and from strains of alpha-toxin-producing staphylococci.

D006377	T-Lymphocytes, Helper-Inducer	Subpopulation of CD4+ lymphocytes that cooperate with other lymphocytes (either T or B) to initiate a variety of immune functions. For example, helper-inducer T-cells cooperate with B-cells to produce antibodies to thymus-dependent antigens and with other subpopulations of T-cells to initiate a variety of cell-mediated immune functions.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

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.
