The effect of interferons (IFNs) type I (alpha/beta) and type II (gamma) on the stimulation of H2-D(d) (class I) and beta-2 microglobulin genes transcription was analysed in IFN-sensitive (w.t.) and IFN-resistant Friend erythroleukemia cells (FLC).

The results reported in the present paper suggest that the IFN-gamma is able per se to increase the expression of H2-D(d) and beta-2 microglobulin genes, since a reduced but clearly evident stimulation of the expression of these genes was observed in the FLC clone totally resistant to type I IFN.

Abstract

The effect of interferons (IFNs) type I (alpha/beta) and type II (gamma) on the stimulation of H2-D(d) (class I) and beta-2 microglobulin genes transcription was analysed in IFN-sensitive (w.t.) and IFN-resistant Friend erythroleukemia cells (FLC). Type I IFN enhances the expression of H2-D(d) and beta-2 microglobulin genes in w.t. FLC but does not modulate the expression of these genes in clones resistant to IFN-alpha/beta. IFN type II treatment of w.t. and IFN-alpha/beta resistant cell lines results in an increased expression of H2-D(d) and beta-2 microglobulin genes, while being ineffective in the cell clone resistant to both types of IFNs. In this cell system the effect(s) of IFN type II is in part mediated by the induction of IFN-beta. The results reported in the present paper suggest that the IFN-gamma is able per se to increase the expression of H2-D(d) and beta-2 microglobulin genes, since a reduced but clearly evident stimulation of the expression of these genes was observed in the FLC clone totally resistant to type I IFN.
