Organoid Models to Study Human Infectious Diseases

Infectious diseases have become significant events that threaten global public health and economic development. Since the 20th century, multiple outbreaks of infectious diseases have gradually deepened humanity's understanding of viral infections, prevention and treatment. Organoids possess a high degree of similarity to human physiological states and have strong self-organising capabilities. Research on infectious diseases based on organoids offers significant advantages in terms of availability, editability and diversity. In this perspective, we briefly introduce the development of organoids, focusing on historically significant infectious diseases that have caused fatal harm to human health, such as HIV, ZIKV, SARS-CoV-2 and MPXV. We further summarise relevant research on the pathogenic mechanisms of these viruses based on organoid models, host reactivity, and therapeutic strategies. Finally, we list the latest research techniques combined with organoid models, discuss the challenges faced in the development of organoids and look forward to the future prospects of organoids in vaccine and drug development.
