Abstract

Insights

Targeting Kaposi's sarcoma-associated herpesvirus (KSHV) lytic replication is crucial for preventing KSHV-related cancers. New therapies aim to inhibit viral replication or induce lytic replication for tumor cell death.

Area of Science:

  • Virology
  • Oncology
  • Infectious Diseases

Background:

  • Kaposi's sarcoma-associated herpesvirus (KSHV) is linked to Kaposi sarcoma, primary effusion lymphoma, and multicentric Castleman disease.
  • Current treatments for KSHV-associated malignancies are suboptimal and toxic, with no established therapeutic guidelines.
  • Antiherpesvirus drugs show inconsistent efficacy against KSHV in its latent state.

Purpose of the Study:

  • To review the role of KSHV lytic replication in disease pathogenesis.
  • To assess advancements in targeting KSHV lytic replication for preventing KSHV-related malignancies.

Main Methods:

  • Review of current research on KSHV pathobiology and therapeutic strategies.
  • Investigation of novel antiviral agents and cellular process targets.
  • Exploration of lytic induction therapy for tumor cell death.

Main Results:

  • New inhibitors of KSHV lytic replication are under development.
  • Novel therapeutic modalities targeting virus-hijacked cellular processes are being explored.
  • Lytic induction therapy aims to promote tumor cell death by reactivating latent KSHV.

Conclusions:

  • KSHV lytic replication is critical in KSHV-associated tumorigenesis.
  • Targeting viral replication and cellular processes is a promising strategy.
  • Combination therapies, including antivirals and lytic inducers, are being investigated.

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Viruses with RNA Genomes

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Viral Replication: Lytic Cycle01:20

Viral Replication: Lytic Cycle

Bacteriophages, or phages, are viruses that specifically infect bacteria. Among them, T-even bacteriophages, such as T4, exhibit a well-characterized lytic replication cycle in Escherichia coli (E. coli). This process ensures the rapid proliferation of the virus while ultimately leading to the destruction of the bacterial host.Attachment and DNA InjectionThe infection process begins with the recognition and binding of the T4 phage to the E. coli cell surface. Tail fibers of the phage...

Lytic Cycle of Bacteriophages01:30

Lytic Cycle of Bacteriophages

Bacteriophages, also known as phages, are specialized viruses that infect bacteria. A key characteristic of phages is their distinctive “head-tail” morphology. A phage begins the infection process (i.e., lytic cycle) by attaching to the outside of a bacterial cell. Attachment is accomplished via proteins in the phage tail that bind to specific receptor proteins on the outer surface of the bacterium. The tail injects the phage’s DNA genome into the bacterial cytoplasm. In the...

Inhibitors of Viral Protein Synthesis01:30

Inhibitors of Viral Protein Synthesis

Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
