J Virol 2022 Jun 27:e0192621. Epub 2022 Jun 27.

Section of Virology, Department of Microbial Sciences, Faculty of Health and Medical Sciences, University of Surreygrid.5475.3, Guildford, Surrey, United Kingdom.

Virion host shutoff (vhs) protein is an endoribonuclease encoded by herpes simplex virus 1 (HSV1). vhs causes several changes to the infected cell environment that favor the translation of late (L) virus proteins: cellular mRNAs are degraded, immediate early (IE) and early (E) viral transcripts are sequestered in the nucleus with polyA binding protein (PABPC1), and dsRNA is degraded to help dampen the PKR-dependent stress response. To further our understanding of the cell biology of vhs, we constructed a virus expressing vhs tagged at its C terminus with GFP. Read More

Viruses 2022 Jun 13;14(6). Epub 2022 Jun 13.

Department of Veterinary Pathobiology, College of Veterinary Medicine, Oklahoma State University, 208 N McFarland Street, RM 250 McElroy Hall, Stillwater, OK 74078, USA.

A corticosteroid antagonist impairs Herpes Simplex Virus 1 (HSV-1) productive infection and explant-induced reactivation from latency, suggesting corticosteroids and the glucocorticoid receptor (GR) mediate certain aspects of these complex virus-host interactions. GR-hormone complexes regulate transcription positively and negatively, in part, by binding GR response elements (GREs). Recent studies revealed infected cell protein 0 (ICP0), ICP4, and ICP27 promoter/cis-regulatory modules (CRMs) are cooperatively transactivated by GR and Krüppel-like factor 15 (KLF15), which forms a feed-forward transcription loop.
