Complementary DNA clones encoding mouse cytokine synthesis inhibitory factor (CSIF;
interleukin-10), which inhibits cytokine synthesis by TH1 helper T cells, were isolated and
expressed. The predicted protein sequence shows extensive homology with an
uncharacterized open reading frame, BCRFI, in the Epstein-Barr virus genome, suggesting
the possibility that this herpes virus exploits the biological activity of a captured cytokine
gene to enhance its survival in the host.
