AI Article Synopsis

  • Kaposi's sarcoma-associated herpesvirus (KSHV) is linked to several cancers, including Kaposi's sarcoma and primary effusion lymphoma.
  • The study investigated how cigarette smoke concentrate (CSC) affects KSHV infection in human foreskin fibroblasts, finding that CSC-treated cells were 50% less infected than untreated ones.
  • Additionally, the results suggest that CSC inhibits KSHV infection during a later stage of cell entry, highlighting its potential as an inhibitor of KSHV.

Article Abstract

Kaposi's sarcoma-associated herpesvirus (KSHV) is etiologically associated with Kaposi's sarcoma (KS), primary effusion lymphoma(PEL), multicentric Castleman disease, and other tumors. Progression of KS is dictated by an aberrant production of inflammatory cytokines and increase in KSHV infection of cells. In this study, we analyzed the effect of cigarette smoke concentrate (CSC) on KSHV infection of human foreskin fibroblasts (HFF) using real time quantitative RT-PCR. Our results demonstrated that the CSC-treated cells supported 50% lower infection of KSHV when compared to the untreated cells. Radiolabeled-binding assays indicated that CSC inhibited KSHV infection of cells at a post attachment stage of entry. Taken together, we report for the first time the ability of CSC to specifically inhibit KSHV infection of cells.

Background: Human herpesvirus-8 (HHV8) can present with cutaneous or extracutaneous manifestations. While violaceous skin lesions characterize cutaneous Kaposi sarcoma, extracutaneous HHV8 is challenging to diagnose due to nonspecific symptoms.

Objectives: We evaluated the role of microbial cell-free DNA next-generation sequencing (mcfDNA NGS) in diagnosing HHV8-related illness.

Kaposi Sarcoma (KS) is a vascular tumor originating from endothelial cells and is associated with human herpesvirus 8 (KSHV) infection. It disproportionately affects populations facing health disparities. Although antiretroviral therapy (ART) has improved KS control in people with HIV (PWH), treatment options for advanced KS remain limited.

Epigenetic and epitranscriptomic regulation during oncogenic -herpesvirus infection.

Oncogenic gamma herpesviruses, including Epstein-Barr Virus (EBV) and Kaposi's Sarcoma-associated Herpesvirus (KSHV), are opportunistic cancer-causing viruses and induces oncogenesis through complex mechanisms, which involves manipulation of cellular physiology as well as epigenetic and epitranscriptomic reprogramming. In this review, we describe the intricate processes by which these viruses interact with the epigenetic machinery, leading to alterations in DNA methylation, histone modifications, and the involvement of non-coding RNAs. The key viral proteins such as EBNA1 and LMP1 encoded by EBV; LANA and vGPCR encoded by KSHV; play pivotal roles in these modifications by interacting with host factors, and dysregulating signaling pathways.

Mouse models of Kaposi sarcoma-associated herpesvirus (KSHV).

Infection with Kaposi sarcoma-associated herpesvirus (KSHV) is a prerequisite for the development of several human cancers, including Kaposi sarcoma and primary effusion lymphoma. Efficient long-term infection with KSHV and subsequent virally induced cell transformation is limited to humans, resulting in a lack of small animal models for KSHV-driven malignancies. Various attempts to create a mouse model for KSHV include infection of humanized mice, generating transgenic mice that ectopically express viral proteins, and grafting KSHV-infected tumor, primary, or immortalized cells onto immunodeficient mice.

Kaposi's sarcoma-associated herpesvirus (KSHV) is a human gammaherpesvirus associated with Kaposi's sarcoma and B cell malignancies. Like all herpesviruses, KSHV contains conserved envelope glycoproteins (gps) involved in virus binding, entry, assembly, and release from infected cells, which are also targets of the immune response. Due to the lack of a reproducible animal model of KSHV infection, the precise functions of the KSHV gps during infection are not completely known.
