Nervous necrosis virus (NNV) causes significant losses in marine fish aquaculture. This study introduces an aptamer-based high-throughput screening (AHTS) model for rapidly identifying natural compounds effective against NNV.
Area of Science:
- Aquaculture
- Virology
- Biotechnology
Background:
- Nervous necrosis virus (NNV) is a major pathogen in marine fish aquaculture, causing substantial economic losses worldwide.
- Current methods for detecting NNV and evaluating antiviral efficacy, like RT-qPCR, are costly and time-consuming.
- Aptamers offer a promising alternative for diagnostics and therapeutics due to their specificity, stability, and low cost.
Purpose of the Study:
- To establish an aptamer (GBN34)-based high-throughput screening (GBN34-AHTS) model.
- To enable efficient selection and evaluation of natural ingredients against NNV infection.
- To provide a rapid, sensitive, and accurate method for identifying antiviral compounds.
Main Methods:
- Development of a GBN34 aptamer.
- Establishment of a high-throughput screening (HTS) platform utilizing the GBN34 aptamer.
- Application of the GBN34-AHTS model to screen natural ingredients for anti-NNV activity.
Main Results:
- The GBN34-AHTS model demonstrated high-speed, sensitive, and accurate screening capabilities.
- The AHTS strategy significantly reduced experimental costs and shortened the screening cycle.
- The model proved effective in identifying natural ingredients with potential anti-NNV properties.
Conclusions:
- The GBN34-AHTS model is an efficient and cost-effective tool for selecting natural antiviral compounds against NNV.
- This rapid screening approach can accelerate the discovery of treatments for NNV and potentially other viral diseases in aquaculture.
- The study highlights the potential of aptamer-based HTS in combating aquatic viral pathogens and improving aquaculture sustainability.
