The field of m(6)A modification and epitranscriptomics has recently attracted much attention. More methods allowing for precise m(6)A site profiling and location are developed and crucial players of m(6)A modification machinery are increasingly identified. Although some challenges remain, m(6)A modification is found to modulate almost all aspects of RNA metabolism, such as splicing, stability, structure, translation, and export. Thus, m(6)A modification adds a new layer of post-transcriptional gene expression regulation, and it is implicated in T cell response to HIV infection, type I interferon production, and T cell differentiation and homeostasis...

Mycoplasma pneumoniae has been associated with respiratory tract infections. Mycoplasma pneumoniae pneumonia-related pleural effusion is rarely reported. Extra-pulmonary abnormalities such as encephalitis, myocarditis, glomerulonephritis, and myringitis have been reported. However pulmonary manifestations in systemic lupus erythematosus include pneumonitis, pleurisy, interstitial lung disease, and thromboembolic disease. We present the case of a 26-year-old male who came for evaluation of fever, cough, and shortness of breath with right-sided chest pain...

Objectives  We report a patient who had a working diagnosis of transverse myelitis secondary to a lupus exacerbation. As his clinical course evolved, continued vigilance clarified that he was in fact suffering from a nosocomial infection caused by vancomycin-resistant Enterococcus (VRE). Methods  We performed a retrospective review of the patient's medical record. Results  Despite radiographic improvement, he did not improve clinically following immunosuppressive therapy including plasma exchange. Once meningitis was diagnosed and treated, he improved rapidly...

La/SS-B (or La) is a 48 kDa RNA-binding protein and an autoantigen in autoimmune disorders such as systemic lupus erythematosus (SLE) and Sjögren's syndrome (SS). La involvement in regulating the type I interferon (IFN) response is controversial - acting through both positive and negative regulatory mechanisms; inhibiting the IFN response and enhancing viral growth, or directly inhibiting viral replication. We therefore sought to clarify how La regulates IFN production in response to viral infection. ShRNA knockdown of La in HEK 293 T cells increased Sendai virus infection efficiency, decreased IFN-β, IFN-λ1, and interferon-stimulated chemokine gene expression...

Canine kobuviruses (CaKoVs) were first identified in diarrhoeic and asymptomatic dogs in 2011 in the USA. Subsequent studies have demonstrated a worldwide distribution of these viruses, but it is not clear if CaKoVs play a role as enteric pathogens of dogs. More recently, CaKoV RNA has been detected in wild carnivores, including red fox, golden jackal, side-striped jackal and spotted hyena. In this study, we addressed the hypothesis that wolves are susceptible to CaKoV infections. A total of 185 wolf stool samples were collected from necropsied animals and from transects in the Liguria, Piemonte and Valle D'Aosta regions of Italy, and CaKoV RNA was identified in two of these specimens...

How and why we break tolerance to self-proteins still remains a largely unanswered question. Neutrophils have been identified as a rich source of autoantigens in a wide array of autoimmune diseases that arise as a consequence of different environmental and genetic factors, e.g. rheumatoid arthritis (RA), lupus, vasculitis, cystic fibrosis (CF) etc. Specifically, neutrophil extracellular trap (NET) formation has been identified as a link between innate and adaptive immune responses in autoimmunity. Autoantigens including neutrophil granular proteins (targeted by anti-neutrophil cytoplasmic antibodies, ANCA) as well as post-translationally modified proteins, i...

Although neurological manifestations of systemic lupus erythematosus (SLE) are well recognised, myelopathy complicating SLE is rare. A 35-year-old woman presented with non-specific symptoms and a respiratory tract infection but had serological evidence of SLE. She subsequently deteriorated rapidly, developing a catastrophic spinal cord syndrome. Her initial MRI was normal; but after 1 month, her encephalopathy having progressed, repeat imaging showed characteristic myelitic changes. She responded only slowly to a combination of cyclophosphamide and corticosteroids...

M H Hristova, V S Stoyanova
Many complement structures and a number of additional factors, i.e. autoantibodies, receptors, hormones and cytokines, are implicated in the complex pathogenesis of systemic lupus erythematosus. Genetic defects in the complement as well as functional deficiency due to antibodies against its components lead to different pathological conditions, usually clinically presented. Among them hypocomplementemic urticarial vasculitis, different types of glomerulonephritis as dense deposit disease, IgA nephropathy, atypical haemolytic uremic syndrome and lupus nephritis are very common...

BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic systemic inflammatory autoimmune disease, the etiology of which remains only partially characterized. Strong evidence implicates chronic infections in the development and chronicity of autoimmune conditions. Recently, an association has been demonstrated between periodontitis and rheumatoid arthritis. Such observations have led to the investigation of the possible role of periodontitis and oral dysbiosis in other systemic inflammatory conditions, including SLE...

Breast milk is not only a completely adapted nutrition source for the newborn but also an impressive array of immune-active molecules that afford protection against infections and shape mucosal immune responses. Decisive imprinting events might be modulated during the first months of life with potential health long-term effects, enhancing the importance of breastfeeding as a major influence on the immune system correct development and modifying disease susceptibility. The aim of this review was to clarify the link between breastfeeding and autoimmune diseases, inquiring the related mechanisms, based on data available in the literature...
