Achaete-scute complex homologue 2 (Ascl2) has been reported to induce the differentiation and activation of follicular helper T (TFH) cells, which are essential for development of Sjögren's syndrome (SS). This study examined whether Ascl2 plays a role in the development of SS. NOD/ShiLtJ mice were injected with an Ascl2-overexpression vector, and the infiltration of lymphocytes into salivary and lacrimal glands was assessed. The expression of inflammatory cytokines and chemoattractants for T or B cells was measured...

Sjögren's syndrome (SjS) is a chronic autoimmune epithelitis in which cell apoptosis promotes the formation of inflammatory lesions. We used immunohistochemistry and TUNEL to assay B cell infiltration and apoptosis in salivary gland tissue from 16-week-old NOD/LtJ mice with SjS. In co-cultures of primary salivary glandepithelial cells (SGECs) and spleen B cells, we assessed SGEC viability and apoptosis using CCK8 assays and flow cytometry. ELISAs were employed to assess cytokine levels in culture medium. Leptin protein, leptin receptor (OB-R), pro- and anti-apoptotic proteins, and Jak2/Stat3/ERK signaling molecules were analyzed using western blotting...

Rheumatic Autoimmune Inflammatory Diseases such as Sjögren's and lupus lack modern treatments. Less than 5% of drugs approved by the FDA from 2014 to mid-2016 had a RAID indication. Many RAID standard-of-care drugs were repurposed based on serendipitous observations, similarity-of-disease categorization, and/or off-target effects. Recently, drug repurposing has become more intentional, relying on an evolving awareness of molecular underpinnings, as well as a better understanding of drug-target interactions by computational modeling...

BACKGROUND: For patients with atrial fibrillation, non-vitamin K oral anticoagulants, or NOACs (dabigatran, rivaroxaban, edoxaban, and apixaban) have been proven non-inferior or superior to warfarin in preventing stroke and systemic embolism, and in risk of haemorrhage. In the pivotal NOAC studies, quality of warfarin treatment was poor with mean time in therapeutic range (TTR) 55-65%, compared with ≥70% in Swedish clinical practice. METHODS: We compared NOACs (as a group) to warfarin in non-valvular atrial fibrillation, studying all 12,694 patients starting NOAC treatment within the Swedish clinical register and dosing system Auricula, from July 1, 2011 to December 31, 2014, and matching them to 36,317 patients starting warfarin using propensity scoring...

Immunoproteasome activation in immune cells is involved in the modulation of immune responses. Increasing evidence indicates that proteasome inhibitors show beneficial effects in treating autoimmune diseases, but it remains unclear whether proteasome inhibition is an effective approach for suppressing autoimmune development in Sjögren's syndrome (SS). Our previous work has demonstrated a critical role for Th17 cells in the development of experimental SS (ESS) in mice. In this study, we detected high levels of low-molecular-weight protein 7 (LMP7), a key subunit of the immunoproteasome, in Th17 cells from ESS mice...

Acquired Gitelman's syndrome (GS) associated with Sjögren syndrome (SS) is rare. A 50-year-old woman was admitted to our department because of nausea, acratia and sicca complex. Laboratory tests after admission showed renal failure, hypokalaemia, metabolic alkalosis, hypomagnesaemia and hypocalciuria, all of which met the diagnostic criteria for GS. Diagnostic evaluation identified primary SS as the cause of the acquired GS. Light microscopy of the renal tissue from the patient showed severe membranoproliferative glomerunephritis and tubulointerstitial nephritis...

Sjögren's syndrome (SS) is a common, autoimmune exocrinopathy distinguished by keratoconjunctivitis sicca and xerostomia. Patients frequently develop serious complications including lymphoma, pulmonary dysfunction, neuropathy, vasculitis, and debilitating fatigue. Dysregulation of type I interferon (IFN) pathway is a prominent feature of SS and is correlated with increased autoantibody titers and disease severity. To identify genetic determinants of IFN pathway dysregulation in SS, we performed cis-expression quantitative trait locus (eQTL) analyses focusing on differentially expressed type I IFN-inducible transcripts identified through a transcriptome profiling study...

Gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone, and luteinizing hormone orchestrate the reproduction cycle and regulate the sex steroid secretion from the gonads. In mammals, GnRH1 is secreted as a hormone from the hypothalamus, whereas both GnRH1 and GnRH2 are present as neurotransmitters/peptides in various tissues, where the peptides exert many different effects. mRNA coding for GnRH1 and GnRH2 have been described in the human gastrointestinal tract, and GnRH has been found in both submucosal and myenteric neurons...

BACKGROUND & AIMS: Sjögren's syndrome and autoimmune pancreatitis (AIP) are disorders with decreased function of salivary, lacrimal glands, and the exocrine pancreas. NOD/ShiLTJ mice and mice transduced with the cytokine BMP6 develop Sjögren's syndrome and chronic pancreatitis and MRL/Mp mice are models of AIP. CFTR is a ductal Cl(-) channel essential for ductal fluid and HCO3(-) secretion. We used these models to ask: is CFTR expression altered in these diseases, does correction of CFTR correct gland function, and most notably, does correcting ductal function correct acinar function...

Toll-like receptor 7 (TLR7) is associated with the pathophysiology of systemic lupus erythematosus and Sjögren syndrome, well-known diseases accompanying interstitial cystitis (IC). We studied TLR7 expression in the bladder of patients with Hunner-type IC (HIC) and its functional roles in bladder inflammation and nociception using mice. Bladder biopsy specimens were obtained from patients with HIC. Specimens from the noncancerous portion of the bladder of patients with bladder cancer served as controls. The specimens were examined by immunohistochemistry and real-time polymerase chain reaction of TLR7...
