RIDA_v1.0 — Russian Immune Diversity Atlas

The Russian Immune Diversity Atlas (RIDA_v1.0) is the primary dataset for this paper. It is a multi-site PBMC biobank collected to study immune diversity and type 2 diabetes ancestry-associated immune differences across the Russian Federation.

RIDA_v2.0 extends the atlas with an additional site in Ufa (Bashkortostan) but is outside the scope of this paper.

Scope

  • v1.0 (this paper): 4 sites — Moscow, Kazan, Grozny, Yakutsk
  • v2.0: adds Ufa — out of scope for the current paper

Data Types (per paper scope)

  • PBMC isolation and cryopreservation
  • Genotyping data (ancestry separation via ADMIXTURE)
  • Single-cell PBMC profiling (scRNA-seq / scATAC-seq)
  • Immune profiling (flow cytometry, functional assays)
  • Clinical metadata (T2D status, anthropometrics, biochemistry panels)
