Tailored Preclinical Research for Parapoxvirus of Reindeer Virus in Therapeutics & Diagnostics

Overview

The Parapoxvirus of Reindeer (PRV) belongs to the Parapoxvirus genus and targets reindeer together with caribou and both domestic and wild ungulate animals. Infected animals develop skin and mucous membrane lesions due to this virus, which resemble the symptoms caused by the orf virus, which also belongs to the parapoxvirus group. This infection stays localized without affecting the whole body system, but can lead to serious inflammation and additional bacterial infections in specific cases. PRV can sporadically infect humans, resulting in minor skin lesions that clear up without medical intervention. The virus remains viable when exposed to environmental conditions and persists within contaminated environments. Healthcare professionals start the diagnostic procedure by evaluating clinical signs, followed by verification via PCR or electron microscopy. Creative Biolabs offers preclinical research services for virus studies, which involve viral propagation and pathogenesis models as well as antiviral testing. We provide testing environments for in vitro and in vivo evaluations of vaccine candidates, together with antiviral agents and diagnostic technology. Our state-of-the-art laboratory infrastructure provides comprehensive support to advance your virus research studies.

Accelerated PRV Preclinical Research Services

• For Therapeutics Development

In Vitro Antiviral Efficacy Assays

• Cytotoxicity Assays: To determine if the drug or virus causes harm to healthy cells. Common methods include MTT or MTS assays.
• Viral Replication Inhibition Assays: These assays test whether the therapeutic candidate can inhibit the replication of Parapoxvirus (PRV) in cultured cells, typically assessed by qPCR, plaque assays, or RT-PCR.
• Time-of-Addition Studies: Used to determine the best time window for antiviral treatment (e.g., during viral entry, replication, or post-replication).
• Immunofluorescence or Immunohistochemistry: Detects viral antigens to evaluate the reduction in viral load in infected cells.
• Neutralization Assays: Assesses the ability of a therapeutic agent to neutralize the virus in vitro.

In Vivo Efficacy Studies (Animal Models)

• Animal Model Selection: Usually, mice or other small animals (e.g., rabbits) are used for preclinical studies. They are often genetically modified or immune-compromised models to mimic human disease or immune responses.
• Viral Challenge Studies: Mice or other animals are infected with PRV to evaluate the therapeutic candidate's ability to protect or treat the infected animals.
• Dose-Response Studies: To evaluate the optimal therapeutic dose that can safely and effectively control or eliminate the virus.
• Survival Studies: Monitoring animal survival rates to assess whether the treatment increases lifespan or prevents disease progression.
• Tissue Distribution Studies: These studies look at the distribution of the therapeutic agent or virus in the body using techniques like histology, imaging, or tissue biopsy.

• For Diagnostics Development

Antigen Detection Assays

• Enzyme-Linked Immunosorbent Assay (ELISA): This is a common method for detecting PRV-specific antigens in samples.
• Immunohistochemistry (IHC): A technique for visualizing the presence of viral antigens in tissue samples.
• Lateral Flow Assays: A rapid diagnostic tool where PRV antigens bind to specific antibodies on a test strip. These assays provide a quick, on-site diagnostic, ideal for field use.
• Western Blotting: Detects specific viral proteins by using antibodies to identify the presence of PRV antigens in lysates from infected cells or tissues.
• Flow Cytometry-Based Detection: Involves labeling cells with antibodies that recognize PRV antigens, followed by flow cytometry analysis to quantify infected cells in a sample.

Nucleic Acid Detection Assays

• Reverse Transcription PCR (RT-PCR): Used to detect PRV RNA, indicating active viral replication. RT-PCR is commonly employed in diagnosing RNA viruses, especially when the virus is actively replicating.
• Digital PCR (dPCR): This highly sensitive technique is used for precise quantification of nucleic acids. It provides more accurate results for low-abundance viral genomes in clinical samples.
• In Situ Hybridization (ISH): A technique for detecting viral nucleic acids within tissue sections. Labeled probes hybridize to the PRV genome, and the presence of the virus is detected by visualization under a microscope.
• Loop-mediated Isothermal Amplification (LAMP): A rapid and cost-effective nucleic acid amplification technique that can be used for field diagnostics of PRV, detecting viral nucleic acids in blood, swabs, or tissue samples.

Antibody Detection Assays (Serology)

• Enzyme-Linked Immunosorbent Assay (ELISA): Detects antibodies (IgG, IgM) against PRV in serum or plasma.
• Western Blotting: Can be used to confirm the specificity of antibodies against PRV by detecting their binding to specific viral proteins in serum or plasma samples.
• Indirect Immunofluorescence Assay (IFA): Uses fluorescently labeled secondary antibodies to detect the presence of anti-PRV antibodies in serum samples.
• Neutralization Assays: A gold standard for determining the presence of neutralizing antibodies in the serum of infected or vaccinated animals.

Applications

• Veterinary Medicine

The main research focus on PRV examines how it affects reindeer and caribou populations, along with other wildlife and domestic hoofed mammals. Managing outbreaks requires understanding the virus since vulnerable populations are most affected by the disease. Development efforts are underway for vaccines and antivirals that target PRV to help minimize disease impact on affected animal populations.

• Zoonotic Disease Monitoring

PRV infects humans as a zoonotic virus on rare occasions by producing mild skin lesions. Developing diagnostic tools for early detection alongside monitoring human transmission potential helps prevent outbreaks among humans who frequently interact with infected animals.

• Viral Vector Research

Scientists are investigating PRV as a possible gene therapy vector alongside other parapoxviruses. Scientists are examining the potential of the virus to function as a delivery mechanism for therapeutic genes and vaccines, which presents a new method for treatment and immunization.
