    OBJECTIVE: Systemic sclerosis-associated interstitial lung disease (SSc ILD) is the leading cause of death in patients with systemic sclerosis (SSc) , with unclear pathogenesis and limited treatment optio.

    Methods: Single-cell RNA sequencing was performed on 11 transplanted SSc ILD and healthy control lung samples , and single-cell ATAC sequencing was performed on 5 lung samples to identify alterations in SPP1 macrophage chromatin accessibili.

    RESULTS: By scRNA-seq analysis, distinct macrophage subsets were identified in normal and SSc-ILD lungs, and gene expression changes that occurred during the transition of normal macrophages to SPP1 macrophages were determin.

    Conclusions: Our findings reveal potential changes in chromatin structure and transcription factor regulation in pro-fibrotic SPP1 macrophages
