[Activation of the alternative complement pathway by Newcastle disease virus. II) Effects mediated by infected lymphoid cells in vitro].
Murine lymphoid cells, infected in vitro with the virus of Newcastle disease, acquire the ability to activate the alternative pathway of mouse complement. At least two different mechanisms are involved: one dependent on the neuraminidasic activity of NDV, the other due to virus-induced epitopes on the surface of murine lymphoid cells.
