Abstract
The human beta-defensin 2 (HBD 2) is a potent anti-bacterial peptide with a wide spectrum of activity. MEF (myeloid elf-1-like factor) or Elf4, a member of the ETS transcription factor family, has been shown to up-regulate the basal expression of the HBD 2 gene in epithelial cells. The mammalian cell nucleus is organized into distinct nuclear domains, one of which is the PML (promyelocytic leukemia) nuclear body involved in the regulation of transcription. Here, we show that PML stimulated MEF transcriptional activity, resulting in the up-regulation of endogenous HBD 2 expression.
