Scientists from the Genome Institute of Singa – EurekAlert

A team of researchers, led by the Agency for Science, Technology and Researchs (A*STAR) Genome Institute of Singapore (GIS), was awarded the prestigious Chan Zuckerberg Initiative (CZI) Ancestry Network Grant in support of their Asian Immune Diversity Atlas (AIDA) project. The project aims to build a map of cells from the blood of healthy Asian individuals spanning 20 distinct populations from eight Asian countries: Singapore, Japan, South Korea, India, Thailand, Russia, Pakistan and Sri Lanka.

Although Asia accounts for nearly 60 percent of the global population, samples from Asian individuals are under-represented in global genomic databases. AIDA, the flagship project of Human Cell Atlas (HCA) Asia, aims to correct this imbalance by studying how immune cells are affected by age, ethnicity, environment and geography.

With the support of the CZI Ancestry Network grant, AIDA will expand representation of diverse Asian population groups within the HCA, promote research participation across Asia, and maintain long-term community engagement to ensure that the project benefits participating communities. AIDA will also provide a baseline measurement of the immune system (the bodys defence mechanism) in healthy individuals, which will be essential for identifying the abnormalities that occur in diverse immune-related diseases, metabolic disorders and cancers.

The project will sequence millions of individual cells from over 1,000 individuals to study the expression of genes as well as the unique immune cell receptors that are involved in mounting a defence against invading pathogens. This will shed light on the properties of immune cells in healthy individuals and serve as a reference and comparison point for understanding immune aberrations in diseases.

Dr Shyam Prabhakar, Associate Director of Spatial and Single Cell Systems at GIS, said, AIDA is the first large-scale effort to characterise immune cell diversity in Asian populations. It will lay a foundation for Precision Medicine in Asia by facilitating therapies tailored to the specifics of the patient. The curated data will be deposited in public repositories for the benefit of the scientific and clinical communities.

Prof Patrick Tan, Executive Director of GIS, said, GIS is honoured to be part of this pioneering regional collaboration, working towards a unified goal of creating a large-scale map of representative traits of immune cells from healthy Asian individuals. It will help us define the changes that cause immune disorders and eventually develop new treatments.
