Abstract:
The nuclease activity of human interleukin-10, an immunosuppressive cytokine, was predicted on the basis of structural homology between the 97–105 sequence of human interleukin-10 and the DNA/RNA-hydrolyzing fragment of the endogenous differentiation factor for the HL-60 line of human promyelocyte leukemia cells. The human recombinant interleukin-10 was shown to cleave all forms of plasmid DNA. The role of interleukin-10 in the apoptosis induction in monocytic cells was hypothesized.
