Preclinical Research Service for the Development of Hare Fibroma Virus Therapeutics & Diagnostic Strategy

Overview

Hare Fibroma Virus (HFV) represents a DNA virus classified under the Leporipoxvirus genus within the Poxviridae family. The principal host of this virus is the hare because infection results in benign fibromatous skin tumors called fibromas. The tumors usually remain confined to specific areas because they grow slowly and seldom spread beyond their original site. The Hare Fibroma Virus demonstrates similarities with other viruses in the leporipoxvirus group, like the Shope Fibroma Virus, which affects rabbits. Arthropod vectors such as mosquitoes and fleas transmit the virus by moving it from infected animals to healthy hosts. The virus triggers cell multiplication within the dermis after infection, which results in the formation of the typical fibroma lesions. The lesions remain non-fatal in most cases, yet may disappear over time, but often lead to discomfort and mobility problems, which vary based on their size and location. HFV stands out in virology and oncology studies because it interacts distinctively with the host immune system while promoting tumor growth that does not advance quickly into malignancy. Research on HFV reveals important information about how viruses cause tumors alongside their dormant states and interactions with host organisms. Researchers use HFV models to perform comparative studies of various poxviruses, especially those that affect human health. Creative Biolabs provides complete preclinical research capabilities for virus studies and includes work with HFV. We provide services for viral isolation and propagation along with in vivo and in vitro modeling, molecular characterization, and histopathological analysis. Our poxvirus research background enables us to provide support for vaccine development alongside antiviral screening and pathogenesis studies. Our team develops bespoke study designs together with premium data to speed up your research outcomes.

Accelerated Hare Fibroma Virus Preclinical Research Services (Therapeutics & Diagnostics)

• For Therapeutics Development

In Vitro Antiviral Efficacy Assays

• Cytotoxicity Screening: Assesses the potential toxicity of candidate therapeutics to host cells to determine the therapeutic window.
• Viral Replication Inhibition Assay: Measures the ability of the therapeutic agent to reduce viral replication within infected cell cultures (e.g., qRT-PCR, viral plaque assays, or TCID50 assays).
• Viral Entry Inhibition: Assesses the ability of the therapeutic to block the viral entry process into host cells.
• Cell-Based Reporter Assays: Utilizes engineered cells that report viral infection (using luciferase or GFP reporters) to evaluate the effects of antiviral agents.
• Neutralization Assay: Determines whether the candidate drug can neutralize the virus, usually by inhibiting virus binding or entry into host cells.

In Vivo Efficacy Studies (Animal Models)

• Animal Model Selection: Selection of appropriate animal models (e.g., mice, rabbits, or non-human primates) for HFV infection, based on the characteristics of the virus and therapeutic goals.
• Dose-Response Studies: Determining the minimum effective dose of the candidate therapy that provides significant antiviral activity with minimal toxicity.
• Pharmacokinetics (PK) and Pharmacodynamics (PD): Measuring drug levels in the blood, tissue distribution, and half-life in animals, as well as the correlation between drug concentrations and therapeutic effects.
• Virus Titration in Tissues: Assessing the viral load in various tissues (e.g., blood, liver, lung) to determine the effect of the drug on systemic viral spread.
• Histopathology and Immunohistochemistry: Examining tissue samples for damage, immune response, or any adverse effects caused by the therapeutic agent.

• For Diagnostics Development

Antigen Detection Assays

• Enzyme-Linked Immunosorbent Assay (ELISA): A highly sensitive test that uses antibodies to detect specific viral antigens (e.g., viral proteins).
• Immunohistochemistry (IHC): Utilized to detect the presence of viral antigens in tissue samples, allowing for visual localization of the virus in infected tissues.
• Western Blotting: This method is used for detecting specific viral proteins in biological samples. It's more qualitative but can give detailed information on the size and abundance of the detected proteins.
• Lateral Flow Assays (LFA): Rapid diagnostic tests that can be used for point-of-care detection of HFV antigens in bodily fluids (e.g., blood, serum, or urine).

Nucleic Acid Detection Assays

• Next-Generation Sequencing (NGS): This allows for the detection and full genomic analysis of the virus, providing detailed insights into viral variants, mutations, or strains.
• In Situ Hybridization (ISH): A method for detecting specific nucleic acid sequences within tissues. ISH is often used to localize the virus to certain areas of tissue (e.g., infected organs).
• Loop-Mediated Isothermal Amplification (LAMP): A nucleic acid amplification technique that amplifies the virus's genome at a constant temperature, offering a rapid, portable alternative to PCR, often used in field diagnostics.

Antibody Detection Assays (Serology)

• Enzyme-Linked Immunosorbent Assay (ELISA): This is also widely used for detecting antibodies in the serum of individuals exposed to HFV.
• Western Blot: Used for detecting antibodies that react with specific viral proteins, providing detailed information about the immune response to the virus.
• Neutralization Assays: These assays determine whether the serum from an infected individual contains antibodies that can neutralize the virus, blocking its ability to infect cells.
• Seroconversion Testing: Measures the timing and appearance of antibodies in response to infection, which is important for evaluating the immune response over time in vaccinated or infected subjects.

Products for Hare Fibroma Virus Research

Research tools for studying HFV exist only in basic virology research forms. The research tools available comprise viral DNA standards as well as antibodies, together with PCR and histopathology reagents. The specialized nature of Hare Fibroma Virus research results in a limited supply of commercial assay kits and cell lines, which calls for additional development to aid broader research and diagnostic applications.
