Islet autoimmunity in patients with Type 1 Diabetes (T1D) emerges months to years before clinical disease manifestation. However, the precise drivers of T1D remain elusive. Here, the authors leverage longitudinal samples collected within the context of the TRIGR trial and, by performing single-cell transcriptomics and epigenomics, reveal heightened pro-inflammatory cytokine signaling in the myeloid lineage before autoantibody seroconversion, suggesting that genomic differences influence immune regulation and predisposition to T1D.
