Bored of black-box UMAP and clustering in #Cytometry?

GatingTree skips such methods, directly analyses high-dimensional data, builds reproducible tree paths across markers, and reveals group-specific effects.

No dimensionality reduction, just interpretable gates. 🌳

Single-cell analysis reveals how periodic TCR signalling defines the spectrum of Treg and self-reactive T cells—and how HTLV-1 may hijack this for immune evasion and transformation.

The study fills key gaps in Treg biology and viral #immunology.
