Despite advances in understanding systemic lupus erythematosus (SLE) pathogenesis, most clinical trials of new targeted therapies have been met with disappointment. The type I IFN pathway is believed to play an important role in SLE, and the proposed involvement of this pathway helps explain the frustration behind the failure at targeting either IFN-α or the type 1 IFN receptor itself. In this issue of the JCI, Furie et al. report on an intriguing phase 1b study that demonstrates an approach for inhibiting this pathway in the skin using an mAB (BIIB059) that targets the blood DC antigen 2 (BDCA-2) receptor on plasmacytoid DCs (pDCs)...

Background: Consanguineous marriage is defined as inbreeding between second cousins or closer. In such families there will be a potential increase in the autosomal recessive traits with its lethal effect, with an increased risk of morbidity and mortality in the new generation. Inherited bleeding disorders (InBDs) are rare complicated diseases, difficult and expensive to treat, the defect usually due to quantitative or qualitative deficiency of clotting factors, platelets or fibrinolysis. This study attempts to assess the diversity, the frequency and the clinical features of inherited bleeding disorders (InBDs) in central part of Iraq and to determine the state of consanguineous marriage...

Systemic lupus erythematosus (SLE) and Sjögren's syndrome (SS) may coexist, and they are chronic complex disorders, with an autoimmune background, multifactorial etiology, multiple circulating autoantibodies, and variable prognosis. The prominent feature of SS is the impairment of the lacrimal and salivary glands leading to sicca symptoms. This disease may be classified as primary Sjögren's syndrome (pSS), or secondary Sjögren's syndrome (sSS) since it is often associated to other autoimmune disorders, principally SLE, rheumatoid arthritis, and systemic sclerosis...

Interleukin-21 (IL-21), an autocrine cytokine predominantly produced by follicular helper T (Tfh) and T helper 17 (Th17) cells, has been proven to play an important role in the immune system, for example, by promoting proliferation and the development of Tfh and Th17 cells, balancing helper T cell subsets, inducing B cell generation and differentiation into plasma cells, and enhancing the production of immunoglobulin. These effects are mainly mediated by activation of the JAK/STAT, MAPK and PI3K pathways...

Traditionally, chemokine immunobiology has focused on chemotaxis and the positioning of cells at sites of inflammation and within lymphoid organs. More recently, however, regulation of intricate immune responses has emerged as a function attributed to chemokines and their receptors. One such pair, CCR6 and its chemokine ligand CCL20, has been receiving interest for its potential role in the coordination and regulation of humoral immune responses and in particular, memory responses, at the cellular level. B cells up-regulate CCR6 after activation in secondary lymphoid organs; however, its function is still unclear...

CD19+ CD24hi CD38hi cells play an essential role in maintaining immune homeostasis. CD40 signaling is involved in regulating the induction and function of CD19+ CD24hi CD38hi cells. Changes in B-cell subpopulations and CD19+ CD24hi CD38hi cells have been observed in systemic lupus erythematosus (SLE) patients. Whether changes in the B-cell subpopulation are related to the aberrant CD40 signaling in SLE patients remains unclear. In this study, we examined changes in the levels of CD19+ CD24hi CD38hi cells and CD19+ CD24hi CD38low cells in peripheral blood mononuclear cells and the serum level of soluble CD40 ligand (sCD40L) in 30 patients with SLE...

BACKGROUND: Systemic sclerosis (SSc) is a rare autoimmune disease characterized by fibrosis of the skin and the involvement of multiple internal organs. Previous studies reported poorer health-related quality of life (HRQoL) in patients with SSc compared with the general population. However, very little is known about how HRQoL in SSc patients compares with that in patients with other systemic autoimmune diseases, such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and Sjogren's syndrome (SjS)...

Immune homeostasis is critically regulated by the balance between activating and inhibitory receptors expressed on various immune cells such as T and B lymphocytes, and myeloid cells. The inhibitory receptors play a fundamental role in the immune-checkpoint pathway, thus maintaining peripheral tolerance. We recently found that expression of leukocyte immunoglobulin-like receptor (LILR)B4, an inhibitory member of the human LILR family, is augmented in autoantibody-producing plasmablasts/plasma cells of systemic lupus erythematosus (SLE) patients...

Checkpoint blockade immunotherapy has revolutionized the treatment of advanced melanoma, with impressive survival benefits attained through upregulation of the anticancer immune response. Blockade of regulatory checkpoint molecules can, however, also result in aberrant immune activation leading to undesirable inflammation and autoimmunity. Although many genetic determinants have been described in patients with primary autoimmune diseases, it is uncertain whether patients developing autoimmune skin disease as an adverse effect of anti-PD-1 therapy share the same genetic risks...

The complement component C3 is at the heart of the complement cascade. It is a complex protein, which generates different functional activated fragments (C3a, C3b, iC3b, C3c, C3d). C3b is a constituent of the alternative pathway C3 convertase (C3bBb), binds multiple regulators, and receptors, affecting thus the functioning of the immune system. The activated forms of C3 are a target for autoantibodies. This review focuses on the discovery, disease relevance, and functional consequences of the anti-C3b autoantibodies...

Systemic lupus erythematosus (SLE) is an autoimmune disease that has high morbidity and can result in multi-organ damage. SLE is characterized by dysregulated activation of T- and B-lymphocytes and the production of autoantibodies directed against nuclear components. The endonuclease deoxyribonuclease 1 (DNase1) is abundant in blood and a subset of SLE patients have mutations in DNASE1. Furthermore, a report showed that Dnase1-deficient mice develop an SLE-like disease, but these mice also carry a deletion of the gene adjacent to Dnase1, which encodes the chaperone TRAP1/HSP75...
