Although the antiviral activity of erythro-9-(2-hydroxy-3-nonyl)adenine, a potent adenosine deaminase inhibitor, against herpes simplex virus type 1 in cell culture was readily confirmed, the compound was found to be totally ineffective in the treatment of experimentally induced systemic herpes simplex virus type 1 infections in Swiss mice. Data were obtained, however, which clearly indicated that the antiviral potency of 9-beta-D-arabinofuranosyladenine in vivo could be enhanced by the co-administration of low, nontoxic doses of erythro-9-(2-hydroxy-3-nonyl)adenine.

Abnormal tau phosphorylation is a key mechanism in neurodegenerative diseases. Evidence implicates infectious agents, such as Herpes Simplex Virus 1 (HSV-1), as co-factors in the onset or the progression of neurodegenerative diseases, including Alzheimer's disease. This has led to divergence in the field regarding the contribution of viruses in the etiology of neurodegenerative diseases.

Background: Herpes simplex virus type 2 (HSV2) is an important cofactor for HIV acquisition and transmission. Associations between the infections are reexamined in longitudinal data from an HIV prevention trial.
Methods: The HPTN 071 (PopART) trial evaluated a combination prevention intervention in 21 urban communities in Zambia and South Africa.

Zygotic genome activation (ZGA) is crucial for maternal to zygotic transition at the 2-8-cell stage in order to overcome silencing of genes and enable transcription from the zygotic genome. In humans, ZGA is induced by DUX4, a pioneer factor that drives expression of downstream germline-specific genes and retroelements. Here we show that herpesviruses from all subfamilies, papillomaviruses and Merkel cell polyomavirus actively induce DUX4 expression to promote viral transcription and replication.

Background: Neurologic symptoms seen in patients receiving immune checkpoint inhibitors (ICI) may not be entirely caused by immunotoxicity. We aim to highlight these confounding conditions through clinical cases to encourage early recognition and management.
Methods: We describe a series of seven cases from our institution that were treated with ICI and presented with Neurologic symptoms and were diagnosed with superimposed conditions beyond immunotoxicity.

Background: Human papillomavirus (HPV) is a leading cause of cervical cancer, with 14 subtypes classified as high-risk human papillomavirus (HR-HPV). Despite the availability of vaccines, certain regions still experience limited access. Herpes simplex virus type II (HSV-II), a common sexually transmitted infection, is hypothesized to increase the risk of HR-HPV infections.
