Viruses with RNA Genomes

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...

Microorganisms in Medicine and Therapeutics

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Area of Science:

Virology
Immunology
Drug Discovery

Background:

Global efforts are nearing wild poliovirus serotype 1 eradication.
Oral polio vaccines (OPVs) carry a risk of vaccine-associated paralytic polio (VAPP).
Immunodeficiency-associated vaccine-derived poliovirus (iVDPV) poses a threat in B cell-deficient individuals.

Purpose of the Study:

To review progress in developing safe and effective poliovirus antiviral drugs.
To highlight promising antiviral candidates for treating iVDPV infections.
To support the goal of a sustained polio-free world.

Main Methods:

Literature review of poliovirus antiviral research.
Summary of in vitro, in vivo, and clinical trial data.
Analysis of drug candidates targeting poliovirus replication.

Main Results:

Significant advancements in poliovirus antiviral drug discovery.
Identification of several promising antiviral candidates.
Demonstrated efficacy of certain antivirals in preclinical and clinical studies.

Conclusions:

Antiviral drug development is essential for eradicating poliovirus and preventing VAPP.
The Polio Antivirals Initiative (PAI) is key to addressing iVDPV risks.
Continued research and clinical trials are needed to bring effective poliovirus antivirals to fruition.
