    Abstract Lupus nephritis (LN) represents the most severe organ manifestation of systemic lupus erythematosus (SLE) in terms of morbidity and mortality. To reduce these risks, tremendous efforts have been made in the last decade to characterize the different steps of the disease and to develop biomarkers in order to better (i) unravel the pre-SLE stage (e.g., anti-nuclear antibodies and interferon signature); (ii) more timely initiation of therapy by improving early and accurate LN diagnosis (e.g., pathologic classification was revised); (iii) monitor disease activity and therapeutic response (e.g., recommendation to re-biopsy, new urinary biomarkers); (iv) prevent disease flares (e.g., serologic and urinary biomarkers); (v) mitigate the deterioration in the renal function; and (vi) reduce side effects with new therapeutic guidelines and novel therapies. However, progress is poor in terms of improvement with early death attributed to active SLE or infections, while later deaths are related to the chronicity of the disease and the use of toxic therapies. Consequently, an individualized treat-to-target strategy is mandatory, and for that, there is an unmet need to develop a set of accurate biomarkers to be used as the standard of care and adapted to each stage of the disease.

    Abstract The clinical course of systemic autoimmune diseases (SADs) varies greatly, even between individuals with the same disease. Understanding of the immune actors is informative and could lead to significant improvements in diagnosis, monitoring, initial treatment decisions and/or follow-up. However, immunological changes in mononuclear cells associated with SADs have been only partially described, and usually are limited to analysis of peripheral blood cells (less than 5% of the total mononuclear pool). Another limitation is technological, related to utilization of flow cytometry, which remains highly variable with regards to sample preparation, reagents, instrument constraints, and data analysis. As a consequence, and although confirmation conducted by independent teams using multivariate analysis is lacking for proposing to use immunophenotyping in the diagnosis and/or follow-up of patients, there is a consensus of interest for monitoring several mononuclear cell subsets for emerging roles in SADs including memory B cells, effector T cells, and dendritic cells. In the near future and with the development of next generation technologies and standardized operating procedures, it is predicted that flow cytometry will find its place in the development of future personalized medicine in SADs. In addition, better understanding of immunological deregulations (e.g., intracellular phosphoproteins and cytokines, calcium actors) in both human and SAD-prone mouse models, as presented in this special issue, would undoubtedly open new perspectives and applications.

    Abstract Background/objectives: Idiopathic inflammatory myopathies (IIM) diagnosis and sub-classification can be improved by detection of myositis specific antibodies (MSA) as a first step in diagnosis. However, when using semi-quantitative immunodots for MSA detection, clinical assay performance needs to be improved.
    Methods: A retrospective study was done for the "myositis" and "synthetase" immunodots (SRP, NXP2, TIF1gamma, SAE1/2, Mi2, MDA5, Jo1, PL7, PL12, EJ, OJ, KS, ZO and HA) from D-Tek used for 270 patients who had tested positive for MSA in a tertiary laboratory hospital.
    Results: Results from this analysis revealed: (i) none of the 60 healthy controls presented MSA; (ii) a low assay specificity among patients who tested positive for MSA, 128/270 (47%) were labeled IIM based on the manufacturer's recommended threshold; (iii) in non-IIM patients (53%), the MSA spectrum overlaps predominantly with other autoimmune diseases or idiopathic interstitial lung disease; and (iv) use of a clinical cut-off improves assay specificity for anti-SRP, anti-NXP2, anti-MDA5, anti-Jo1 and anti-PL7 Abs.
    Conclusion: Determining the clinical threshold of the semi-quantitative immunodot assay for MSA is effective for improving its capacity to discriminate IIM from non-IIM and, when IIM diagnosis is excluded, another autoimmune disease or an idiopathic interstitial lung disease should be considered in front of a positive MSA.

    Abstract T cells are known to be involved in the pathogenesis of rheumatoid arthritis (RA). Accordingly, and to better understand T cells' contribution to RA, a comprehensive review based on an analysis of the Immune Epitope Database (IEDB) was conducted. An immune CD8+ T cell senescence response is reported in RA and inflammatory diseases, which is driven by active viral antigens from latent viruses and cryptic self-apoptotic peptides. RA-associated pro-inflammatory CD4+ T cells are selected by MHC class II and immunodominant peptides, which are derived from molecular chaperones, host extra-cellular and cellular peptides that could be post-translationally modified (PTM), and bacterial cross-reactive peptides. A large panel of techniques have been used to characterize (auto)reactive T cells and RA-associated peptides with regards to their interaction with the MHC and TCR, capacity to enter the docking site of the shared epitope (DRB1-SE), capacity to induce T cell proliferation, capacity to select T cell subsets (Th1/Th17, Treg), and clinical contribution. Among docking DRB1-SE peptides, those with PTM expand autoreactive and high-affinity CD4+ memory T cells in RA patients with an active disease. Considering original therapeutic options in RA, mutated, or altered peptide ligands (APL) have been developed and are tested in clinical trials.

    Abstract In non-excitable cells, Orai proteins represent the main channel for Store-Operated Calcium Entry (SOCE), and also mediate various store-independent Calcium Entry (SICE) pathways. Deregulation of these pathways contribute to increased tumor cell proliferation, migration, metastasis, and angiogenesis. Among Orais, Orai1 is an attractive therapeutic target explaining the development of specific modulators. Therapeutic trials using Orai1 channel inhibitors have been evaluated for treating diverse diseases such as psoriasis and acute pancreatitis, and emerging data suggest that Orai1 channel modulators may be beneficial for cancer treatment. This review discusses herein the importance of Orai1 channel modulators as potential therapeutic tools and the added value of these modulators for treating cancer.

    Abstract Pathologic type I interferon (T1IFN) expression is a key feature in systemic lupus erythematosus (SLE) that associates with disease activity. When compared to adult-onset disease, juvenile-onset (j)SLE is characterized by increased disease activity and damage, which likely relates to increased genetic burden. To identify T1IFN-associated gene polymorphisms (TLR7, IRAK1, miR-3142/miR-146a, IRF5, IRF7, IFIH1, IRF8, TYK2, STAT4), identify long-range linkage disequilibrium and gene:gene interrelations, 319 jSLE patients were genotyped using panel sequencing. Coupling phenotypic quantitative trait loci (QTL) analysis identified 10 jSLE QTL that associated with young age at onset (<12 years; IRAK1 [rs1059702], TLR7 [rs3853839], IFIH1 [rs11891191, rs1990760, rs3747517], STAT4 [rs3021866], TYK2 [rs280501], IRF8 [rs1568391, rs6638]), global disease activity (SLEDAI-2 K >10; IFIH1 [rs1990760], STAT4 [rs3021866], IRF8 [rs903202, rs1568391, rs6638]), and mucocutaneous involvement (TLR7 [rs3853839], IFIH1 [rs11891191, rs1990760]). This study suggests T1IFN-associated polymorphisms and gene:gene interrelations in jSLE. Genotyping of jSLE patients may allow for individualized treatment and care.

    Abstract Systemic sclerosis (SSc) is associated, in nearly all patients, with autoantibodies (Ab). Accordingly, and in order to identify major (anti-CEN A/B and anti-Topo I) but also minor Abs, the usefulness of combining indirect immunofluorescence (IIF) on HEp-2 cells with an 11 multi-antigenic SSc immunodot was explored. 1689 samples tested at the request of clinicians, were evaluated retrospectively. The positivity rate was 28.8% and the diagnosis of SSc was supported for 232 samples. Two groups of Abs were considered: group 1, Abs (anti-CENP A/B, anti-Topo I) present at elevated levels in SSc patients; group 2, Abs for which the Ab specificity (odds ratio and/or positive predictive value) was improved by using IIF on HEp-2 cells (RNA-Polymerase III, fibrillarin, Th/T0, PM-Scl). Altogether, this study highlights the utility of combining IIF on HEp-2 cells with the SSc immunodot as the first line of an SSc Abs detection/SSc diagnostic strategy.
