Autoimmune diseases may also be reflected in changes in the oral cavity that represent the first sign of the disease, or they may occur simultaneously with or later in the course of the disease. Oral findings are mostly non-specific, and therefore further investigations are needed to exclude or confirm possible diagnoses. This article presents the most important diseases in this research area, divides them into meaningful groups, and highlights the importance of examining the oral cavity for possible manifestations...

Protein folding in the endoplasmic reticulum (ER) is an essential cell function. To safeguard this process in the face of environmental threats and internal stressors, cells mount an evolutionarily conserved response known as the unfolded protein response (UPR). Invading pathogens induce cellular stress that impacts protein folding, thus the UPR is well situated to sense danger and contribute to immune responses. Cytokines (inflammatory cytokines and interferons) critically mediate host defense against pathogens, but when aberrantly produced, may also drive pathologic inflammation...

During induction of trained immunity, monocytes and macrophages undergo a functional and transcriptional reprogramming toward increased activation. Important rewiring of cellular metabolism of the myeloid cells takes place during induction of trained immunity, including a shift toward glycolysis induced through the mTOR pathway, as well as glutaminolysis and cholesterol synthesis. Subsequently, this leads to modulation of the function of epigenetic enzymes, resulting in important changes in chromatin architecture that enables increased gene transcription...

Immune cell activation is a stringently regulated process, as exaggerated innate and adaptive immune responses can lead to autoinflammatory and autoimmune diseases. Perhaps the best-characterized molecular pathway promoting cell activation is the nuclear factor-κB (NF-κB) signaling pathway. Stimulation of this pathway leads to transcription of numerous pro-inflammatory and cell-survival genes. Several mechanisms tightly control NF-κB activity, including the key regulatory zinc finger (de)ubiquitinating enzyme A20/tumor necrosis factor α-induced protein 3 (TNFAIP3)...

Neutrophilic urticarial dermatosis (NUD) is a useful diagnostic term for urticarial lesions that are less pruritic and more painful than conventional urticaria. The histopathologic features include neutrophilic infiltrates in the interstitial dermis with a higher density than idiopathic urticaria. NUD has been associated with several systemic conditions, which are predominantly autoimmune and autoinflammatory in nature. A woman with Crohn disease who developed NUD is described. Literature reports of other conditions in which neutrophilic urticarial dermatosis have been observed are also reviewed and summarized...

IL-36 cytokines have recently emerged as mediators of inflammation in autoimmune conditions including psoriasis vulgaris (PsV) and generalized pustular psoriasis (GPP). This study used RNA-seq to profile the transcriptome of primary epidermal keratinocytes (KCs) treated with IL-1B, IL-36A, IL-36B, or IL-36G. We identified some early IL-1B-specific responses (8 h posttreatment), but nearly all late IL-1B responses were replicated by IL-36 cytokines (24 h posttreatment). Type I and II interferon genes exhibited time-dependent response patterns, with early induction (8 h) followed by no response or repression (24 h)...

Classifying inflammatory skin diseases is challenging, especially for the expanding group of disorders triggered by genetic factors resulting in hyperactivated innate immunity that result in overlapping patterns of dermal and epidermal inflammation with hyperkeratosis. For such conditions, the umbrella term "autoinflammatory keratinization diseases" (AIKD) has been proposed. AIKD encompasses diseases with mixed pathomechanisms of autoinflammation and autoimmunity, and includes IL-36 receptor antagonist (IL-36Ra)-related pustulosis, CARD14-mediated pustular psoriasis, pityriasis rubra pilaris (PRP) type V, and familial keratosis lichenoides chronica (KLC)...

BACKGROUND: Gallstone disease is highly prevalent and is associated with systemic inflammation. AIMS: To determine whether screen-detected gallstones or cholecystectomy are associated with the occurrence of autoimmune and autoinflammatory diseases and the most common subgroups thereof. METHODS: A cohort study of three randomly selected general population samples from Copenhagen was performed. Participants (n = 5928) were examined in the period 1982-1992, underwent abdominal ultrasound examination to detect gallstone disease, and followed through national registers until December 2014 (median 24...

Metabolic syndrome (MetS) is a cluster of metabolic and cardiovascular (CV) risk factors including obesity and visceral adiposity, insulin resistance, dyslipidemia and hypertension contributing to CV mortality. The interface between the metabolic and immune systems has been of great interest recently. These interactions are regulated through genetics, nutritional status, and the intestinal microbiome. Alterations in the immune-metabolic cross-talk contribute to the development of autoimmune diseases. Adipokines exert a variety of metabolic activities contributing to the ethiopathogenesis of MetS and are involved in the regulation of both inflammatory processes and autoimmunity occurring in rheumatic diseases...

Inflammasomes are multimeric protein complexes that promote inflammation (through specific cleavage and production of bioactive IL-1β and IL-18) and pyroptotic cell death. The central role of inflammasomes in combating infection and maintaining homeostasis has been studied extensively. Although inflammasome-mediated inflammation and cell death are vital to limit pathogenic insults and to promote wound healing/tissue regeneration, unchecked/uncontrolled inflammation, and cell death can cause cytokine storm, tissue damage, autoinflammatory and autoimmune diseases, and even death in the afflicted individuals...

PURPOSE OF REVIEW: Understanding the relationship between viral infections and the development of type 1 diabetes (T1D) is essential for T1D prevention. Virus-induced innate immune responses, specifically type I interferon (IFN-I) and the IFN gene signature, orchestrate early events of β-cell dysfunction preceding islet autoimmunity. We summarize recent advances in how IFN-I and the IFN gene signature can drive T1D development. RECENT FINDINGS: IFN-I, particularly IFN-α, and the IFN gene signature have been detected in islets and peripheral blood of T1D patients...

Endoplasmic reticulum (ER) stress triggers or amplifies inflammatory signals and cytokine production in immune cells. Upon the resolution of ER stress, the inducible phosphatase 1 cofactor GADD34 promotes the dephosphorylation of the initiation factor eIF2α, thereby enabling protein translation to resume. Several aminoguanidine compounds, such as guanabenz, perturb the eIF2α phosphorylation-dephosphorylation cycle and protect different cell or tissue types from protein misfolding and degeneration. We investigated how pharmacological interference with the eIF2α pathway could be beneficial to treat autoinflammatory diseases dependent on proinflammatory cytokines and type I interferons (IFNs), the production of which is regulated by GADD34 in dendritic cells (DCs)...

Panniculitides represent a heterogeneous group of inflammatory diseases that are traditionally considered one of the most difficult challenge for clinicians and pathologists. They may occur in a variety of dermato/rheumatologic diseases and are of particular relevance for clinicians dealing with such pathologies, including immune-mediated/autoimmune and autoinflammatory disorders. In fact, panniculitides can be the initial sign of presentation of a dermato/rheumatologic disease, thereby providing the physician with important clues to the correct diagnosis...

Psoriasis is a chronic complex multisystem, inflammatory, skin disorder that causes vasodilatation and hyperproliferation of keratinocytes, whose clinical expression includes a thickened, erythematous skin, often covered with silver gray scales. Psoriasis is a unique disease where both autoimmune and autoinflammatory responses coexist and the balance between the two components is essential in determining its clinical and histopathological presentation. Adaptive immune responses prevail in chronic plaque psoriasis while innate and autoinflammatory responses predominate in pustular psoriasis...

Recognition of pathogens and altered self must be efficient and highly specific to orchestrate appropriate responses while limiting excessive inflammation and autoimmune reaction to normal self. AIM2 is a member of innate immune sensors that detects the presence of DNA, arguably the most conserved molecules in living organisms. However, AIM2 achieves specificity by detecting altered or mislocalized DNA molecules. It can detect damaged DNA, and the aberrant presence of DNA within the cytosolic compartment such as genomic DNA released into the cytosol upon loss of nuclear envelope integrity...

Diabetes mellitus (DM) is not a single disease, but several pathophysiological conditions where synthesis, release, and/or action of insulin are disturbed. A progressive autoimmune/autoinflammatory destruction of islet cells is still considered the main pathophysiological event in the development of T1DM, but there is evidence that T1DM itself is a heterogeneous disease. More than 50 gene regions are closely associated with T1DM and a variety of epigenetic factors and metabolic patterns have been characterized, which may play a role in the development of T1DM...

IL-17-producing γδ (γδ17) T cells form a versatile subset of cells that respond rapidly to innate stimuli and support the pro-inflammatory functions of different myeloid and lymphoid lineages, being particularly critical in the early stages of inflammatory and autoimmune responses. In mice, under homeostatic conditions, these innate-like lymphocytes are pre-programmed in the fetal thymus, through an intricate process involving both T cell receptor-dependent and -independent signals, which allows them to readily produce IL-17 upon stimulation...

At the population level, rheumatoid arthritis (RA) is generally viewed as autoimmune in nature with a small subgroup of cases having a palindromic form or systemic autoinflammatory disorder (SAID) phenotype. Herein, we describe resistant cases of classical autoantibody associated RA that had clinical, genetic and therapeutic responses indicative of coexistent autoinflammatory disease. Five patients with clinically overlapping features between RA and SAID including polysynovitis and autoantibody/shared epitope positivity, and who had abrupt severe self-limiting attacks including fevers and serositis, are described...
