African swine fever virus (ASFV) and porcine epidemic diarrhea virus (PEDV) share a common module that suppresses pig immune cells. Quantum computing validated this network, showing its potential for biological research.
Area of Science:
- Virology and Immunology
- Computational Biology and Quantum Computing
Background:
- African swine fever virus (ASFV) and porcine epidemic diarrhea virus (PEDV) are significant swine pathogens.
- Both viruses suppress macrophage-mediated immune responses in pigs, despite differing in viral biology and cellular tropism.
Purpose of the Study:
- To identify a conserved macrophage suppression module shared by ASFV and PEDV.
- To evaluate quantum computing as an independent framework for validating biological networks.
Main Methods:
- Integrated analysis of public gene expression datasets identified shared downregulated genes between ASFV and PEDV infections.
- A 20-gene core network module was selected and formulated as a 20-qubit Quadratic Unconstrained Binary Optimization (QUBO) problem.
- Community detection and network validation were performed using the Quantum Approximate Optimization Algorithm (QAOA) on quantum simulators and hardware, compared against classical methods.
Main Results:
- A conserved macrophage suppression module shared by ASFV and PEDV was successfully identified.
- QAOA on a protein-protein interaction network reproduced the brute-force optimum, demonstrating successful network validation.
- Performance of QAOA varied with network density and circuit depth, highlighting the impact of network topology and NISQ hardware limitations.
Conclusions:
- The study reveals a conserved immune evasion strategy employed by ASFV and PEDV.
- Quantum computing offers a novel and independent framework for validating complex biological networks.
- Network topology is a critical factor influencing the performance of quantum algorithms on current quantum hardware.
