PKR sensing of mitochondrial dsRNA in childhood Sjogrens disease
ABSTRACT Through our multidisciplinary clinical and research collaboration, we have established a rare cohort of children and adolescents who fulfilled the 2016 adult Sjögren’s disease (SjD) criteria (namely, cSjD for childhood Sjögren’s disease). Since autoimmune SjD typically affects elderly females, whether cSjD is a unique disease entity or an early manifestation of SjD is completely unknown. The overall goal is to characterize mechanisms by which mitochondrial dsRNAs (mtdsRNA) are released into the cytoplasm and activate the cytosolic dsRNA sensor, protein kinase R (PKR), for the proinflammatory signature found in cSjD CD14+ monocytes. Our preliminary data from scRNA-seq of cSjD…
