Systemic Lupus Erythematosus is systematic auto-immune disease characterized by abnormal activation of B cell with production of autoantibodies. Due to its heterogeneous course, there is a need for new markers to help in diagnosing and monitoring disease activity. The aim of this study was to identify the immunopathological role of CD19 and CD81 expression in patients with SLE and their correlation with the disease activity. Peripheral blood (PB) was collected from 40 SLE patients (20 active and 20 inactive) and 20 controls...

Histopathological analyses of muscle specimens from myositis patients indicate that skeletal muscle cells play an active role in the interaction with immune cells. Research over the last few decades has shown that skeletal muscle cells exhibit immunobiological properties that perfectly define them as non-professional antigen presenting cells. They are able to present antigens via major histocompatibility complex molecules, exhibit costimulatory molecules and secrete soluble molecules that actively shape the immune response in an either pro- or anti-inflammatory manner...

In the last decade, metabolism has been recognized as a major determinant of immunological processes. During an inflammatory response, macrophages undergo striking changes in their metabolism. This metabolic reprogramming is governed by a complex interplay between metabolic enzymes and metabolites of different pathways and represents the basis for proper macrophage function. It is now evident that these changes go far beyond the well-known Warburg effect and the perturbation of metabolic targets is being investigated as a means to treat infections and auto-immune diseases...

Monogenic auto-inflammatory diseases are characterized by genetic abnormalities coding for proteins involved in innate immunity. They were initially described in mirror with auto-immune diseases because of the absence of circulating autoantibodies. Their main feature is the presence of peripheral blood inflammation in crisis without infection. The best-known auto-inflammatory diseases are mediated by interleukines that consisted in the 4 following diseases familial Mediterranean fever, cryopyrinopathies, TNFRSF1A-related intermittent fever, and mevalonate kinase deficiency...

At first sight the bleeding disorder hemophilia A seems to have little in common with immune disorders, but immunology research intersects with other disciplines including hematology. Nowadays, the most important complication in the treatment of hemophilia A is the development of neutralizing antibodies (inhibitors) against exogenous administered factor VIII (FVIII), which occurs in approximately 30% of all patients with severe hemophilia A. This antibody response renders FVIII replacement therapy ineffective, thereby increasing the risk for uncontrollable bleeding and morbidity, decreasing quality of life and increasing healthcare costs...

Idiopathic inflammatory myopathy (IIM), commonly referred to as "myositis", is a rare but treatable auto-immune disease that is often misdiagnosed or diagnosed after significant delay. Using three clinical case reports as introductory examples, an overview is given - and pitfalls are discussed - of the diagnosis and treatment of myositis. Disease features are often extra-muscular in nature, may vary considerably between patients, and are frequently non-specific. Myositis-related morbidity is high and myositis can be fatal, mainly due to cancer and interstitial lung disease...

Background: Rheumatoid arthritis (RA) is an auto-immune disease characterized by chronic inflammation of multiple joints. Hypoxia is a constant feature of synovial microenvironment in RA. Fibroblast-like synoviocytes (FLSs), which are potent effector cells in RA. It has been reported that large numbers of monocytes are recruited to the synovium and play an important role in synovial inflammation and tissue destruction in RA. However, the mechanism is still unclear. The aim of this study is to explore the role of hypoxia microenvironment on the recruitment of monocytes and then promote the development of RA...

Nailfold capillaroscopy is an easy, non-invasive technique to assess microvascular involvement in rheumatic diseases. Multiple studies describe capillaroscopic changes in systemic lupus erythematosus (SLE), including a wide range of non-specific findings. On behalf of the European League Against Rheumatism (EULAR) study group on microcirculation in rheumatic diseases, a systematic review was done to obtain all original research studies (in English) in which SLE patients had capillaroscopy. Forty such studies are identified...

The neutrophil appears to be undergoing a renaissance of sorts. While it was for many years thought to be a killing machine brought into tissues to eradicate pathogens, it is now being implicated in many other processes, ranging from acute injury and repair, chronic inflammatory processes, cancer and auto-immunity. Not only is it an effector of the innate immune response, it appears to also potentially contribute to adaptive immunity, implicated in either contributing to the development of specific adaptive immune responses or perhaps even instructing and directing certain adaptive immune responses...

JAK inhibitors have been developed following the discovery of the JAK2 V617F in 2005 as the driver mutation of the majority of non- BCR-ABL1 myeloproliferative neoplasms (MPNs). Subsequently, the search for JAK2 inhibitors continued with the discovery that the other driver mutations ( CALR and MPL ) also exhibited persistent JAK2 activation. Several type I ATP-competitive JAK inhibitors with different specificities were assessed in clinical trials and exhibited minimal hematologic toxicity. Interestingly, these JAK inhibitors display potent anti-inflammatory activity...
