Although herpesvirus saimiri-transformed T lymphocytes retain
multiple normal T-cell functions, only a few changes have been described. By subtractive hybridization, we have isolated a novel cellular gene, ak155, a sequence homolog of the
interleukin-10 gene. Specifically herpesvirus saimiri-transformed T
cells overexpress ak155 and secrete the protein into the
supernatant. In other T-cell lines and in native peripheral blood
cells, but not in B cells, ak155 is transcribed at low
levels. AK155 forms homodimers similarly to interleukin-10. As a
lymphokine, AK155 may contribute to the transformed phenotype of human
T cells after infection by herpesvirus saimiri.
