The Soluble Isoform of CTLA-4 Correlates with Interferon- α Activity in Systemic Lupus Erythematosus.

The Soluble Isoform of CTLA-4 Correlates with Interferon-α Activity in Systemic Lupus Erythematosus. J Rheumatol. 2019 Dec 01;: Authors: Dahal LN, Barker RN, Ward FJ Abstract Systemic lupus erythematosus (SLE) is a multisystem autoimmune disorder characterized by fluctuating levels of immune response hyperactivity, high serum titers of nucleic antigen-specific autoantibodies, and persistent production of type-I interferon (IFN)1 One route to controlling SLE has been to exploit the properties of T cell lymphocyte costimulation inhibitor (CTLA-4), a selective costimulation inhibitor, which suppresses autoantigen-specific T cell response intensity2.

Sjögren's syndrome: Old and new therapeutic targets. J Autoimmun. 2019 Dec 09;:102364 Authors: Mavragani CP, Moutsopoulos HM Abstract Sjögren's syndrome (SS) is a prototype autoimmune disease characterized by oral and ocular mucosal dryness following chronic inflammation of salivary and lachrymal glands, respectively. Profound B cell hyperactivity along with systemic manifestations including fatigue, musculoskeletal complaints, features related to hepatic, pulmonary, renal and nervous system involvement, as well as lymphoma development can be also present. Despite that activation of both inn...

Systemic lupus erythematosus (SLE) is a devastating autoimmune disease in which hyperactive T cells play a critical role. Understanding molecular mechanisms underlying the T cell hyperactivity will lead to identification of specific therapeutic targets. Serine/arginine-rich splicing factor 1 (SRSF1) is an essential RNA-binding protein that controls posttranscriptional gene expression. We have demonstrated that SRSF1 levels are aberrantly decreased in T cells from patients with SLE and that they correlate with severe disease, yet the role of SRSF1 in T cell physiology and autoimmune disease is largely unknown. Here we show ...

Semin Respir Crit Care Med 2019; 40: 235-254 DOI: 10.1055/s-0039-1688448Sjogren's syndrome (SS) is a chronic autoimmune disease characterized by mononuclear cells (principally lymphocytes) infiltrating exocrine glands (e.g., salivary and lacrimal glands), leading to destruction of exocrine epithelial cells and dryness of mucosal surfaces. Cardinal symptoms are dry eyes (xerophthalmia) and dry mouth (xerostomia). Extraglandular sites are affected in 30 to 40% of cases of SS (particularly neurological, kidneys, skin, and lungs). B cell hyperactivity, autoantibody production, and hypergammaglobulinemia are cardinal features o...

This study aimed to uncover the mechanisms that regulate the BAFF expression in SLE B-cells. The results demonstrated that the expression of miR-152-3p was significantly increased in SLE B-cells compared with normal controls. This study confirmed that Kruppel-like factor 5 (KLF5) was a direct target of miR-152-3p, and it could bind to the promoter region of BAFF and inhibit its expression in B-cells. The upregulation of miRNA-152-3p expression decreased the KLF5 expression and increased the BAFF expression in SLE B-cells. Knockdown of miR-152-3p expression inhibited the self-reactivity of SLE B-cells, thereby reducing the ...

Conclusion: Some patients with psychiatric syndromes and increased ANA titers may suffer from psychiatric variants of SLE, even if the American College of Rheumatology criteria for SLE are not met. Whether the psychiatric symptoms in our patient represent a prodromal stage with the later manifestation of full-blown SLE or a subtype of SLE with isolated CNS involvement remains unclear. Regardless, early diagnosis and initiation of immunosuppressive treatment are essential steps in preventing further disease progression and organ damage. Intrathecal ANAs with extractable nuclear antigen differentiation may be a more sensitiv...

In conclusion, activation of pDCs and glandular epithelial cells by external or endogenous triggers induce the production of type I IFN through TLRs. Type I IFN will lead to BAFF release and activation of B cells with consequent auto-antibody production. Moreover, type I IFN may directly activate T cells which secrete pro-inflammatory cytokines, thus contributing to induce a pro-inflammatory environment. In this scenario, a feedback loop may be postulated between IFN-α production and immune complex formation which will amplify the effect of activated type I IFN system on onset or perpetuation of SS. Role of Chemokin...

We report significantly correlated loci and highlight those containing genome‐wide associations and candidate genes for respective disorders. We also used the LDSC method to characterize genetic correlations among the immune‐related phenotypes. We discuss our findings in the conte xt of relevant genetic and epidemiological literature, as well as the limitations and caveats of the study.
