Fujitsu Limited and Kirin Holdings Company, Limited announced a pioneering research breakthrough that has for the first time identified a previously unknown mechanism in the gut-brain axis associated with citicoline, a compound known to support cognitive function. The achievement was made possible using advanced AI-driven digital transformation (DX) technologies and experimental validation, representing a world-first application of this approach in food functionality and health science research.
The research employed Quantitative Systems Pharmacology (QSP) models, an AI-enhanced computational framework that integrates physiological networks, and combined them with real-world experimental validation to reveal how citicoline influences neural signaling through the intestinal nervous system. This insight opens new opportunities for food innovation, health science, and the application of digital technologies in life sciences.
Understanding the Breakthrough: AI and Simulation-Driven Health Research
Traditionally, scientific research into nutritional compounds and pharmaceuticals has relied on lengthy, costly laboratory experiments and animal testing. These methods, while valuable, have limitations in speed, scalability, and relevance to human physiology. The 富士通–Kirin collaboration harnessed AI-enhanced in silico simulations to predict biological effects of citicoline, which were later confirmed through cell-based experimental models.
By constructing a QSP model that incorporated metabolic profiles and biological receptor data, the research team identified that citicoline may activate cholinergic signaling within the gut nerve axis and increase levels of acetylcholine, a neurotransmitter linked to memory and cognitive function, at intestinal synapses. Importantly, further laboratory validation confirmed activation of neuronal pathways through the intestinal environment.
This combination of AI prediction and experimental evidence represents a significant departure from conventional discovery models and illustrates how digital transformation technologies can accelerate innovation in food science and health research.

日本のハイテク産業が意味するもの
AI-Driven DX Strengthens Japan’s R&D Competitiveness
Japan has long emphasized innovation in technology and life sciences. By successfully applying AI-enabled drug discovery DX technologies to food functionality research, Fujitsu and キリン have demonstrated a novel use case that can reshape how research and development is conducted across industries.
The deployment of AI-based QSP models reflects a broader trend in the adoption of digital technologies across high-value sectors, including biotechnology, pharmaceuticals, food science, and health tech. These capabilities can significantly shorten R&D cycles, reduce costs, and increase the likelihood of successful outcomes without reliance on animal testing.
For Japanese tech firms, this breakthrough reinforces the value of investing in AI, simulation technologies, and computational biology platforms, which are emerging as core competencies with global market relevance.
Cross-Industry Influence of AI in Life Sciences
The implications of this research extend beyond food functionality into the wider health and life sciences ecosystem. As AI-driven DX gains traction, technology providers with strengths in:
- Advanced analytics and machine learning
- Cloud computing and scalable computing resources
- Data integration platforms
- In silico simulation and modeling frameworks
will find growing demand from pharmaceutical companies, medical research institutions, and health startups seeking to integrate AI into discovery and development processes.
This evolution aligns with Japan’s broader strategy to support digital transformation across healthcare, biotechnology, and industrial sectors, positioning the nation as a hub for AI-augmented scientific discovery.
