Production of interferon-beta by murine T-cell lines induced by 10-carboxymethyl-9-acridanone.
Besides the established T-cell property of producing gamma interferon (IFN-gamma), murine T cells additionally possess the ability to produce IFN-alpha and IFN-beta when appropriate inducers such as 10-carboxymethyl-9-acridanone (CMA) or Newcastle disease virus (NDV) are used. Interleukin 2 (IL-2)-dependent murine T-cell lines, but not purified resting splenic T cells, responded to CMA and NDV with production of IFN-alpha, beta. The IFN production by these T cells was not restricted to a special subset, since T cells expressing the Lyt 1+2- and the Lyt 1-2+ phenotype responded to these inducers with IFN production. After prolonged passaging of the T-cell lines in IL-2-containing medium, the ability to respond to CMA with production of antiviral activity was sustained longer than the ability for concanavalin A-induced IFN-gamma production. Whereas the NDV-induced T-cell supernates contained both IFN-alpha and IFN-beta, the induction with CMA resulted exclusively in the synthesis of IFN-beta by the T-cell lines.[1]References
