Isolation of Daudi Cells with Reduced Sensitivity to Interferon. II. On The Mechanisms of Resistance

Isolation of Daudi cells with reduced sensitivity to interferon. I. Characterization.

Treatment of Daudi cells with successively increasing concentrations of interferon-alpha resulted in the selection of a cell population which multiplied in the continued presence of 10(4) units/ml of interferon-alpha. A number of clones of interferon-resistant Daudi cells were isolated from this population. Two clones, DIF2 and DIF3, were found to exhibit moderate and pronounced resistance, res...

Isolation of Rickettsia prowazekii with reduced sensitivity to gamma interferon.

The growth of Rickettsia prowazekii Madrid E was monitored in mouse L929 cells subcultured for several weeks in the presence of gamma interferon (IFN-gamma) to determine whether the rickettsiae would be eliminated from or would persist in these cultures. R. prowazekii exhibited two distinct patterns in these IFN-gamma-treated cultures. In some cases, IFN-gamma-induced inhibition of rickettsial ...
