Systemic Lupus Erythematosus and dysbiosis in the microbiome: cause or effect or both?

Systemic Lupus Erythematosus and dysbiosis in the microbiome: cause or effect or both? Curr Opin Immunol. 2019 Oct 04;61:80-85 Authors: Silverman GJ, Azzouz DF, Alekseyenko AV Abstract Throughout our lives we are immersed in, and colonized by, immense and complex microbial communities. These microbiota serve as activators and early sparring partners for the progressive construction of the layers within our immune defenses and are essential to immune homeostasis. Yet, at times imbalances within the microbiota may contribute to metabolic and immune regulatory abnormalities that underlie the development of inflammatory and autoimmune diseases. Here, we review recent progress in investigations of the microbiome, with emphasis on the gut microbiota associated with systemic autoimmunity. In particular, these studies are beginning to illuminate aspects of the pathogenesis of Systemic Lupus Erythematosus, and may suggest that interconnections with specific disease-associated patterns of dysbiosis within gut communities are bidirectional and mutually reinforcing.

This study was designed to evaluate whether helminthic infections suppress the natural development of systemic lupus erythematosus (SLE) in NZBWF1 mice. Infection of NZBWF1 SLE-prone mice with two nematodes failed to establish long-lasting settlement. However, the Hymenolepis microstoma (Hm) rodent tapeworm successfully established long-term parasitization of NZBWF1 mice and was used to evaluate the suppressive effects of helminth infection. Ten-month-old NZBWF1 mice developed symptoms including autoantibody generation, proteinuria, glomerular histopathology, and splenomegaly, but mice infected with Hm at 2 months of age...

a Rocha Pitta MG Abstract BACKGROUND: Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by chronic and progressive inflammation that can cause a high degree of disability in affected individuals. Proinflammatory cytokines play central roles in the development of degradative and inflammatory responses in RA. IL-29 has been identified in RA and reported as a biomarker of the disease. OBJECTIVE: To analyze serum levels and accuracy of IL-29 in RA patients compared to healthy subjects and patients with other rheumatic diseases. METHODS: IL-29 serum levels were measured in 121 patients ...

Autoimmune diseases are characterized by dysregulated immune tolerance to self and inflammatory damage to tissues and organs. The development of inflammation involves multiple innate and adaptive immune pathways. Inflammasomes are multimeric cytosolic protein complexes that form to mediate host immune responses upon recognizing pathogen ‐ or damage‐associated molecular patterns via pattern‐recognition receptors (PRRs). The accelerating pace of inflammasome research has demonstrated important roles for inflammasome activation in many pathologic conditions, including infectious, metabolic, autoinflammatory, and autoimm...

Abstract Chronic inflammation has profound tumor-promoting effects. Inflammatory cells are the key players in immunosurveillance against tumors, and immunosuppression is known to increase the risk of tumors. Autoimmune diseases, which manifest as loss of self-tolerance and chronic immune dysregulation, provide a perfect environment for tumor development. Aside from managing the direct inflammatory consequences of autoimmune pathogenesis, cancer risk profiles should be considered as a part of a patient's treatment. In this review, we describe the various associations of malignancies with autoimmune diseases, specif...

Authors: Umnyakova ES, Zharkova MS, Berlov MN, Shamova OV, Kokryakov VN Abstract Antimicrobial peptides (AMPs) were firstly discovered as cytotoxic substances that killed bacteria. Later they were described as biologically active peptides that are able not only to kill invaders but also to modulate host immunity. In particular, it is shown that human antimicrobial peptides are able to influence the activity of different innate and adaptive immunity components, thus, obviously, they also participate in autoimmune processes. In this review we discuss the nature of human AMPs and analyze their role in such autoimmune ...

Systemic lupus erythematosus (SLE) is the prototype of connective tissue diseases that can present the complete spectrum of neurological and psychiatric dysfunctions. The precise etiological diagnosis of neuropsychiatric systemic lupus erythematosus (NPSLE) is rather difficult to be established and it i...
