In dermal samples, for the STAT1 gene, most cells were expressed only in SLE samples, for instance, classical monocytes, exhausted B cells, follicular helper T cells, intermediate monocytes, myeloid dendritic cells, naïve CD8 T cells, natural killer cells, non-classical monocytes, plasmablasts, plasmacytoid dendritic cells, progenitor cells, and T regulatory cells were found (Fig. 10E). Here, STAT1 is linked to systemic lupus erythematosus.
