28, 2025) – Scientists from five Asian countries — Singapore, South Korea, Japan, Thailand, and India — have created the world’s first Asian Immune Diversity Atlas (AIDA), a comprehensive single-cell resolution map of immune cells from diverse Asian populations. Published in Cell, this study could lead to more accurate diagnoses and personalized treatments for Asian populations. With new single-cell genomic tools, scientists can now examine individual immune cells in far greater detail. “With most existing cell atlases predominantly focused on European populations, the Asian Immune Diversity Atlas represents an effort to characterize cellular profiles of healthy Asian donors residing in Asia,” said Prabhakar. “AIDA reveals the healthy immune baseline in Asian populations at an unprecedented resolution, and provides detailed reference ranges for blood immune cells in Asians,” he added.
