The role of nuclear factors as "Find-Me"/alarmin signals and immunostimulation in defective efferocytosis and related disorders.

The role of nuclear factors as "Find-Me"/alarmin signals and immunostimulation in defective efferocytosis and related disorders. Int Immunopharmacol. 2020 Jan 10;80:106134 Authors: Tajbakhsh A, Rezaee M, Barreto GE, Moallem SA, Henney NC, Sahebkar A Abstract Efferocytosis as an apoptotic cell (AC) clearance mechanism facilitates the removal of dangerous and damaged cells, an important process in regulating normal homeostasis. Failure to correctly execute apoptosis and efferocytosis is associated with atherosclerosis, as well as chronic inflammatory and autoimmune disorders such as systemic lupus erythematosus (SLE). Effective and timely efferocytosis involves various molecules that act as "Find-Me" signals or as alarmins to quickly allow identification by phagocytic cells. In recent years, most of these molecules have been investigated, but less attention has been paid to the nuclear molecules associated with efferocytosis of ACs and necrotic cells (NCs). These molecules have several functions including acting as alarmin signals for faster recognition of ACs, facilitating the cleanup of ACs and for maintaining self-tolerance. The same group of molecules is also implicated in several inflammatory and autoimmune diseases. Previous studies have shown that these molecules also serve as targets for pharmacological agents such as necrostatins, recombinant Fcnb, anti-histone, neutralizing antibodies, calbiochem, aminophylline, activated prot...

e;zquiz Aguirre S, Sánchez Landa E Abstract INTRODUCTION: whether hypovitaminosis D is an overarching cause of increased mortality or a prognostic marker of poor health has not been well elucidated. OBJECTIVES: we sought to determine the association of serum 25-hydroxyvitamin D [25-(OH)-D3] levels with the clinical biochemical parameters and mortality risk in chronic diseases. METHODS: we reviewed the clinical charts and collected the clinical biochemical parameters of patients diagnosed with chronic conditions who had at least one 25-(OH)-D3 determination, with or without calcium and vitamin D su...

Abstract Oxidative stress is the off-balance of antioxidants and free radicals. All kinds of disease and disorders give rise to oxidative damage including autoimmune diseases. An autoimmune disorder is a pathological condition characterized by the breakdown of self-tolerance of the immune system in the body. Immunological processes against tissues and organs leading to enhanced oxidative stress and in turn, misbalance of oxidative stress aggravates the pathobiology of the disease. Highly reactive nature of free radicals, for example, hydroxyl, superoxide ions, alter DNA, protein, and lipids in the body which augme...

Authors: Crincoli V, Piancino MG, Iannone F, Errede M, Di Comite M Abstract Aims: Systemic Lupus Erythematosus (SLE) is a connective tissue disease characterized by a wide range of pleomorphic pictures, including mucocutaneous, renal, musculoskeletal and neurological symptoms. It involves oral tissues, with hyposalivation, tooth decay, gingivitis, angular cheilitis, ulcers and glossitis. Temporomandibular disorders represent a heterogeneous group of inflammatory or degenerative diseases of the stomatognatic system, with algic and/or dysfunctional clinical features involving temporomandibular joint (TMJ) and related...

The objective of the study is to evaluate the sensitivity of the new criteria for the classification of systemic lupus erythematosus (SLE), when applied to real SLE cases. We retrospectively reviewed the electronic medical records of 100 consecutive patients who visited St. Luke ’s International Hospital. Patients were included if they were clinically diagnosed as having SLE and excluded if they had other autoimmune disease or if they were less than 18 years old. Each patient was evaluated if they satisfied the American College of Rheumatology (ACR) 1997 classification c riteria (1997 criteria), 2012 Systemic Lu...

Abstract Numerous epidemiological studies have suggested a link between vitamin D deficiency and the development of various autoimmune diseases, including diabetes mellitus type 1, rheumatoid arthritis, inflammatory bowel disease, multiple sclerosis or systemic lupus erythematosus. More recently, such a link has been also proposed for autoimmune bullous diseases (AIBD). This is a relatively rare and potentially life-threatening, organ-specific group of inflammatory skin diseases characterized by the presence of tissue-bound and circulating autoantibodies against various molecules present in desmosomes (in pemphigu...

Abstract OBJECTIVE: Systemic lupus erythematosus (SLE) is a complex multi-systemic autoimmune disease with variable levels of activity that may wax and wane within the same patient over the years. In view of the scarcity of data about lupus in the East Malaysian population, we aimed to study the disease activity and damage index in patients with SLE hospitalized in a tertiary center in Sabah, East Malaysia. METHODS: We retrospectively studied all patients with SLE admitted from 1 January 2013 to 31 December 2015. Demographic data, clinical features, treatment received, SLEDAI and SLICC/ACR (Systemic Lupus Int...

Abstract Endoplasmic reticulum (ER)-associated degradation (ERAD) is a mechanism against ER stress, wherein unfolded/misfolded proteins accumulated in the ER are transported to the cytosol for degradation by the ubiquitin-proteasome system. The ER resident E3 ubiquitin ligase HRD1 has been identified as a key ERAD factor that directly catalyzes ubiquitin conjugation onto the unfolded or misfolded proteins for proteasomal degradation. The abnormally increased HRD1 expression was discovered in rheumatoid synovial cells, providing the first evidence for HRD1 dysregulation involved in human inflammatory pathogenesis. ...

Abstract BACKGROUND: The immune system is one of the most complex regulatory systems in the body and is essential for the maintenance of homeostasis. Despite recent breakthroughs in immunology, the regulation of the immune system and the etiology of autoimmune diseases such as lupus remain unclear. Systemic lupus erythematosus is a systemic autoimmune disease with abnormally and inconsistently expressed pro-inflammatory cytokines. Pyroptosis is a pro-inflammatory form of programmed cell death that is associated with systemic lupus erythematosus. The thymus and spleen are important immune organs involved in systemi...

Abstract Despite its long history of untoward side effects of a systemic autoimmune disease, drug-induced lupus can be difficult to recognize because of the disconnect between chronic drug usage and onset of symptoms. In this case, the patient was treated with hydralazine for two years when symptoms were initially reported, but a diagnosis of hydralazine-induced lupus was not considered for another half year. Despite treatment with steroidal and nonsteroidal anti-inflammatory medications during this period, rheumatologic symptoms and signs continued to deteriorate, consistent with the diagnosis of systemic lupus e...
