[Identification of lymphocyte populations producing alpha-interferon by monoclonal antibodies]

Two different leucocyte populations producing alpha-interferon can be defined by monoclonal antibodies. One non glass adherent population produces interferon after induction with Herpes and Sendaï viruses. It is characterized by anti-D44 antibody, defining both some T and NK cells, but not by anti-D66 antibody with selective reactivity for T cells. The other glass adherent population is identified by OKM1 antibody, which defines about 70% of the monocytes, and can be induced only with Sendaï virus.
