Recent developments such as large language models and foundation models trained on massive datasets are also discussed. Looking ahead, we explore future directions in analytical methodology, including mathematical modeling, interpretable artificial intelligence, and multimodal learning that integrates various data types. We also introduce the concept of the digital twin—a virtual representation of an individual patient that simulates disease progression and treatment response—as a promising concept for advancing precision medicine. Finally, we discuss the essential role of physicians in the development and implementation of machine learning tools and discuss emerging ethical issues such as fairness, privacy, and patient autonomy.

RNA Velocity, introduced in 2018, offers a groundbreaking solution. By leveraging unspliced pre-mRNA and spliced mRNA information, RNA Velocity models infer instantaneous gene expression change rates and effectively predict future transcriptional states over hour-long timescales. This review charts the evolution of this powerful concept, beginning with foundational principles and mathematical models of transcriptional dynamics. We explore Velocyto’s pioneering implementation, discuss successes and limitations, and then examine second-generation advanced computational tools that generalize the framework, including scVelo, dynamo, and CellRank. A dedicated section highlights growing applications in allergy and immunology research, where these methods reveal novel disease mechanisms in asthma, atopic dermatitis, and chronic inflammation by analyzing immune cell differentiation and state transitions. We explored modern frontiers, including RNA Velocity integration with spatial and multimodal data, and the latest deep learning-based methods. Finally, we addressed the current challenges and remaining limitations of RNA Velocity analysis, offering insights into best practices and future directions. Throughout, we emphasize applications to allergic and immune-mediated diseases—including asthma, atopic dermatitis, and prurigo nodularis—to guide researchers and clinicians in allergy and immunology.
