In eukaryotes, 21- to 24-nucleotide-long RNAs engage in sequence-specificinteractions that inhibit gene expression by RNA silencing.This process has regulatory roles involving microRNAs and, inplants and insects, it also forms the basis of a defense mechanismdirected by small interfering RNAs that derive from replicativeor integrated viral genomes. We show that a cellular microRNAeffectively restricts the accumulation of the retrovirus primatefoamy virus type 1 (PFV-1) in human cells. PFV-1 also encodesa protein, Tas, that suppresses microRNA-directed functionsin mammalian cells and displays cross-kingdom antisilencingactivities. Therefore, through fortuitous recognition of foreignnucleic acids, cellular microRNAs have direct antiviral effectsin addition to their regulatory functions.

Note added in proof: Recent findings indicate that a single8-oligonucleotide seed (small RNA positions 1 to 8 from the5' end) is sufficient to confer strong regulation by animalsmiRNAs. Thus, fortuitous targeting of foreign RNAs by cellularmiRNAs could be widespread (21, 22).
