Margaret C. Neville, Jenifer Monks, in Encyclopedia of Reproduction (Second Edition), 2018. Pemphigus is an AID characterized by blistering of the mucosae and skin that results from an autoantibody attack on desmoglein proteins. However, desmosomes linking the epithelial cells are rare in the lactating gland, presumably because they would impair the shape change that must occur in order for the lumen to accommodate the accumulating milk during lactation. Consider ordering with Epithelial Cell … The desmosomal cadherin desmoglein-1 (DSG1) is an essential intercellular adhesion molecule that is altered in various human cutaneous disorders; however, its regulation and function in allergic disease … Desmoglein-1 (DSG1), a desmosomal protein, maintains the structure of epidermis through its adhesive function. This degree of cell type specificity may reflect the major IF genes that are expressed, although additional levels of regulation are possible. An effective epidermal barrier requires structural and functional integration of adherens junctions, tight junctions, gap junctions (GJ), and desmosomes. They also form connections between the epithelial cells and the basal myoepithelial cells. Since most of the structural variability between Dsg family members rests in this unique region, it is possible that individual family members regulate distinct signaling pathways. The discovery that Dsg1 is the target of ETA (Table 5.1) provides unique verification for the role of Dsg1 in pemphigus foliaceus. Autoantibody production in these diseases is typically polyclonal, with IgG4 produced early in the disease, and IgG1 later; both of these IgG isotypes may cross the placenta.213 Other important factors may be involved in mediating pemphigus as well. Barbara Ranscht, in Handbook of Cell Signaling (Second Edition), 2010. Desmoglein­1 has been shown to be important in establishing cell­cell adhesion and function in the epidermis. In pemphigus foliaceus IgG autoantibodies are developed against desmoglein 1 and inhibit its adhesive function … Desmosomes form strong cell–cell interactions that contribute to development of the mammary epithelium. Avoid using sera exhibiting a high level of lipemia, hemolysis, icterus or microbial growth. No anticoagulants, or preservatives should be added. Desmoglein Antibodies (1 and 3) Test Resources. Indeed, injection of either pemphigus foliaceus IgG or ETA into mouse epidermis produces an identical phenotype.62 These observations, along with the genetic disorders discussed below, firmly establish the role of desmosomal cadherins in epidermal function and integrity. This syn-drome comprises severe dermatitis, multiple allergies and metabolic wasting (SAM) and can manifest as ichthyosiform erythroderma at birth.1 … The latter provide a link (via desmoplakin) to intermediate filaments. HTSS results in the early hair loss (within the first decade of life) in the patients, with no other skin, hair, or nail symptoms. Netherton syndrome is an autosomal recessive disease caused by mutations in the serine protease inhibitor LEKT1 (lymphoepithelial Kazal-type-related inhibitor).81 Loss of this protease inhibitor results in excessive tryptic and chymotryptic enzyme activity attributed to members of the kallikrein protease family. Desmosomal cadherins comprise two separate subfamilies, the Desmocollins (DSC) and Desmogleins (DSG), each represented by three members (DSC-1, -2, -3, and DSG-1, -2, -3) [52, 53]. However, heterozygous mutations in DSG1 in humans result in abnormal … The cytoplasmic tail of Desmoglein-1 interacts with desmoplakins, plakoglobin and plakophilins. Currently, four desmoglein subfamily members have been identified and … Involucrin, an early differentiation marker expressed in the … ▼ Gene Function Amagai et al. Adult PV is endemic in Brazil, and a correlation has been noted between individuals with anti-Dsg-1 and a history of infectious disease, notably onchocerciasis and Chagas disease.219 It is interesting to speculate that transplacental transfer of anti-Dsg-1 in endemic areas may be meant to protect the offspring from infection without causing pemphigus, owing to the skewed fetal expression of desmogleial isoforms as outlined previously. Courtesy of Dr. Vijay Chaddah, Grey Bruce Health Services, Owen Sound, Ontario. Hypotrichosis and recurrent skin vesicles. Associations between HLA class II alleles and PV have been reported (66–69). In contrast, the desmosomal cadherin isoforms and armadillo plaque proteins that are used for adhesion vary significantly between tissues. These conditions may cause aberrant test results. This H-CDR3 is critical in the antibody function and antigen specificity, suggesting that agents interfering with these areas may block pathogenic antibodies. Desmosomes demonstrate Ca2 +-dependent adhesion, though the precise mechanism of desmosomal cadherin adhesion and specificity are not understood (Sheikh, Ross, & Chen, 2009). It is assumed that the MHC molecule forms a complex with peptides from Dsg3 (70). Serine aspartate repeat containing protein D (SdrD) is involved in adhesion to human squamous cells isolated from the nose. Neutrophil recruitment to skin by IgA against Dsgs and Dscs causes blistering, with mucosa, palms, and soles usually spared. Not only is clinical disease painful, but it subjects the neonate to risks of infection, fluid loss, and weight loss due to diminished feeding.213 No preventive measures are known. An additional truncation mutant in the desmocollin-2 gene has been associated with recessive ARVC/D with mild palmoplantar keratoderma and woolly hair. For example, in cardiac myocytes desmosomes associate with desmin, whereas complexus adherente in endothelia interact with vimentin (Getsios et al., 2004). These structures have been found to be essential for branching morphogenesis of the mammary gland264 and for formation of acinar cultures from purified MECs.265 However, Pitelka and her colleagues showed almost 40 years ago that as the alveoli become secretory the desmosomes disappear,6 likely to allow the profound shape changes in the epithelial cells as the lumens expand and contract with the accumulation and ejection of milk. Keratinocyte structure, adhesion, and signaling modulated by Erbin and/or DSG1. DSCs and DSGs contain characteristic intracellular domains that diverge from those of the classical cadherins and interact with either of the amadillo family proteins plakoglobin and plakophilin. ! Currently, four desmoglein subfamily members have been identified and all are members of the cadherin cell adhesion molecule superfamily. However, heterozygous mutations in DSG1 in humans result in abnormal differentiation, as does downregulation of DSG1 in human skin organ culture, suggesting that it may have important signaling functions. Green, in Progress in Molecular Biology and Translational Science, 2013. The disease strikes men and women of any age equally, but is rarely seen in children. V. Todorović, ... K.J. Desmosomes govern epidermal integrity while GJs facilitate small molecule transfer across cell membranes. The Role of Desmoglein 1 in Gap Junction Turnover Revealed through the Study of SAM Syndrome J Invest Dermatol . Diseases associated with DSG1 include Erythroderma, Congenital, With Palmoplantar Keratoderma, Hypotrichosis, And Hyper-Ige and Palmoplantar Keratoderma I, Striate, Focal, Or Diffuse… Desmoglein-1 has been shown to be important in establishing cell-cell adhesion and function in the epidermis. Antibodies specific for Dsg have been characterized and cloned from patients with PV (71). Plate 29-13. Erbin binds to the cytoplasmic tail of DSG1 but not to the intracellular cadherin-like sequence (ICS) that binds plakoglobin (Pg), a protein important for desmosome integrity and function. There are three clinically distinct types of PG: pemphigus vulgaris (PV), the most common form characterized by severe blistering of the skin and mouth (Plate 29-13); pemphigus foliaceus (PF), in which itchy (rather than painful) blisters occur on the face, scalp, back, and chest but not in the mouth; and paraneoplastic pemphigus, a very rare and painful form of the disease that affects the lips, mouth, and throat of individuals already suffering from cancer. By continuing you agree to the use of cookies. Desmoglein 1, which is a cadherin type cell-cell adhesion molecule in desmosomes, is targeted in two different skin diseases, pemphigus foliaceus, and SSSS. However, heterozygous mutations in DSG1 in humans result in abnormal differentiation, as does downregulation of DSG1 in human skin organ culture, suggesting that it may have important signaling functions. Patients die due to sudden cardiac arrest arising from arrhythmia. Steven M. Anderson, ... Margaret C. Neville, in Knobil and Neill's Physiology of Reproduction (Fourth Edition), 2015. In women with active or historical blistering skin disease, serial measurements of autoantibody titers can guide treatment, which may include plasma exchange and/or corticosteroids.222,223 Infants of these women are monitored for disease and treated symptomatically. There are two classes of desmosomal cadherins, desmogleins and desmocollins, and each of these classes contains several isoforms (Delva et al., 2009). Desmoglein 1 (Desmoglein 1, DSG1) Short Description: Component of intercellular desmosome junctions. IF proteins are differentially expressed during development and in different tissues. Thus, these alleles are the restricting elements of the T cell response to Dsg3 in PV patients. Desmogleins are also targets for both bacterially produced and endogenous proteases. In the autoimmune skin disease pemphigus foliaceus, autoantibodies to Desmoglein­1 can cause the loss of keratinocyte adhesion resulting in blisters. Desmoglein-1 (DSG1), a desmosomal protein, maintains the structure of epidermis through its adhesive function. Nonetheless, mature, functionally competent desmosomes require at least one member from each of the desmosomal cadherin family, leading to the suggestion that they may involve heterodimers of desmocollins and desmogleins. Green, in, Progress in Molecular Biology and Translational Science, Encyclopedia of Reproduction (Second Edition), Nancy L. Reinsmoen, ... Chih-hung Lai, in, Emery and Rimoin's Principles and Practice of Medical Genetics, Pemphigus is an autoimmune disease, in which antibodies specific for, Steven M. Anderson, ... Margaret C. Neville, in, Knobil and Neill's Physiology of Reproduction (Fourth Edition), Desmosomes are localized spot adhesions on the lateral sides of cells that use, Handbook of Cell Signaling (Second Edition), Desmosomal cadherins comprise two separate subfamilies, the Desmocollins (DSC) and, Encyclopedia of Biological Chemistry (Second Edition). DSG1 desmoglein 1 [ (human)] Work exposes a new pathway by which a desmosomal cadherin called Dsg1, which is lost early in head and neck cancer progression, suppresses cancer … Pemphigus vulgaris patients with both mucosal and skin lesions have antibodies to both DSG-3 and DSG-1. These antibodies bind to calcium dependent adhesion molecules in cell surface desmosomes, notably desmoglein 1(DSG-1) in pemphigus foliaceus and desmoglein 3 (DSG-3) in pemphigus vulgaris.

The neonatal epidermal Dsg pattern more closely resembles that of adult mucous membranes, suggesting that high levels of Dsg-3 can compensate for antibody-mediated loss of Dsg-1.215 Functional studies using transgenic mice engineered to express human Dsg-3 in their epidermis confirmed protection from human anti-Dsg-1 antibodies. Emerging evidence implicates these unique subdomains of Dsg1 in epidermal differentiation through regulation of epidermal growth factor receptor (EGFR)–extracellular-signal-regulated kinase (Erk) signaling axis. Desmoglein-1 (DSG1), a desmosomal protein, maintains the structure of epidermis through its adhesive function. SPPK results in the epidermal thickening of the palms and soles and, depending on the genetic background, is often combined with the appearance of woolly hair and cardiomyopathy. PF results in disruption of intercellular adhesion in a cell sheet leading to its acantholysis due to autoantibody against Dsg1. Woolly hair with and without cardiomyopathy. 4.10.900.10, 1 hit: InterPro i: View protein in InterPro IPR002126, Cadherin-like_dom IPR015919, Cadherin-like_sf IPR020894, Cadherin_CS IPR000233, Cadherin_cytoplasmic-dom IPR027397, Catenin_binding_dom_sf IPR009123, Desmoglein … The protein encoded by this gene has been identified as the autoantigen of the autoim… Two types of glycosylated, type I transmembrane adhesive cadherin proteins are found in the desmosome, Pemphigus is an AID characterized by blistering of the mucosae and skin that results from an autoantibody attack on. This cleavage removes sequences required for cell–cell adhesion in the superficial epidermis, resulting in focal lesions that histologically resemble pemphigus foliaceus.79 The specificity of the protease is quite remarkable; no other protein is known to be cleaved by ETA or the other closely related proteases produced by staphylococcal bacteria.80 Dramatic evidence for this specificity is provided by staphylococcal scalded skin syndrome (SSSS), which is observed in infants and immune-compromised patients. Endemic form of the disease is caused by an as of yet unknown environmental factor. Request PDF | Desmoglein-1, differentiation, and disease | Desmoglein-1 (DSG1), a desmosomal protein, maintains the structure of epidermis through its adhesive function. These data are interesting with respect to viral pathogenicity and also provide evidence that desmosomal cadherins modulate the epithelial phenotype. In the autoimmune skin disease pemphigus foliaceus, autoantibodies to Desmoglein-1 … Impaired expression of intercellular adhesion molecule desmoglein 1 (DSG1) is sufficient for impaired barrier function … Via adaptor proteins (e.g., Grb2), the guanyl nucleotide exchange factor son of sevenless (SOS) allows exchange of GDP for GTP on Ras and thus activation of this small GTPase. The toxin exfoliative toxin A (ETA), produced by the Staphylococcus bacteria that causes bullous impetigo, is a serine protease that cleaves Dsg1 after residue 381 between ECs 3 and 4 (Table 5.1). Aseptically collect 5-8 mL of blood by approved venipuncture procedures. The negative charge of residues of DR 70 and 71 residues in DRB1∗04:02 and the DQB 57 residue of DQB1∗05:03, for example, confers selective binding to self peptides that have a positive charge at the P4 pocket in the peptide-binding groove. Reduced proteolysis of Dsg1 was proposed to be a central contributor to the aberrant desquamation and keratinization in this disorder.82 Kallikrein-5-dependent proteolysis of Dsg183 and ADAM-dependent proteolysis of Dsg2 have also been suggested to promote their turnover in oral squamous cell carcinoma cells.84 Further, retention of Dsg2 was observed in the epidermis of patients with a recessive loss of function mutation in ADAM17 resulting in neonatal-onset inflammatory skin and bowel disease.85 Finally, Dsg2 cleavage via cysteine proteinases was also reported to contribute to stimulus-induced apoptosis in intestinal epithelial cells.86 Together, these observations suggest that aberrant proteolysis of desmogleins contributes to human disease pathogenesis. Dsgs and Dscs are thought to function primarily in mediating homo- and/or heterophilic calcium-dependent adhesion across the membranes of adjacent cells. LEKTI deficiency causes abnormal desmosome cleavage in the upper granular layer through degradation of desmoglein 1 due to stratum corneum tryptic enzyme and stratum corneum chymotryptic enzyme … The Dsc isoforms are further subdivided into two types, a longer a form and a shorter b form. DSG1 (Desmoglein 1) is a Protein Coding gene. Copyright © 2021 Elsevier B.V. or its licensors or contributors. The extracellular domain of desmosomal cadherins is composed of five cadherin domains and confers homophilic or heterophilic binding interactions with other members of the desmosomal cadherin family (Figure 242.1). Even so, treated patients do not ever fully recover and the disease becomes chronic in nature. The C-terminus of Dp mediates its interaction with IF. In pemphigus vulgaris and pemphigus foliaceus, autoantibodies against desmoglein 3 and desmoglein 1 (Amagai & Stanley, 2012), respectively, recognize and bind to desmoglein and inhibit its adhesive function… These proteins are the target antigens in epidermal blistering diseases such as pemphigus, caused by autoantibody-mediated acantholysis (disruption of keratinocyte adhesion).213 To date, four isoforms of desmogleins (Dsg1-4) have been identified in humans.214 These isoforms are differentially expressed in various epithelial tissues, so that antibody specificity plays a significant role in determining the clinical outcome. Some patients with severe dermatitis, multiple allergies, and metabolic wasting (SAM) syndrome, caused by biallelic desmoglein 1 … (1991) demonstrated that desmoglein-1 is the antigen target in the autoimmune disease of skin, pemphigus foliaceus; DSG3 (169615) is the antigen target in pemphigus vulgaris… Nancy L. Reinsmoen, ... Chih-hung Lai, in Emery and Rimoin's Principles and Practice of Medical Genetics, 2013. This disease was discussed in Chapter 28 as an example of type II (antibody-mediated) hypersensitivity. The ErbB family includes four receptors with tyrosine kinase activity (ErbB1 [also known as EGFR], ErbB2, ErbB3, ErbB4), which form homodimers and/or heterodimers upon ligand binding. First, proteins of the armadillo family, plakophilins (Pkp) and plakoglobin (Pg), interact directly with the desmosomal cadherins. Pemphigus is an autoimmune disease, in which antibodies specific for desmogleins (Dsg3) cause loss of keratinocyte cell adhesion and blisters. Mouth Blisters of Pemphigus Vulgaris, B.R. None found for this test Please visit our Clinical Education Center to stay informed on any future publications, webinars, or other education … This physical linkage is mediated by two sets of proteins (Nekrasova and Green, 2013). The specific desmogleins and desmocollins that are expressed in cells vary with their tissue of origin. Sparse, fragile hair with abnormal hair follicles, impaired hair keratinization and epidermal hyperproliferation. of-function mutations in the desmoglein 1 (DSG1) gene. In the presence of DSG1, the scaffolding protein Erbin skews the fate of keratinocytes toward differentiation by binding SHOC2 and inhibiting formation of Ras/Raf complexes. Kaelyn D. Sumigray, Terry Lechler, in Current Topics in Developmental Biology, 2015. Mutations resulting in premature truncation or mislocalization of desmocollin-2 have been identified in autosomal-dominant ARVC/D (Heuser et al., 2006; Syrris et al., 2006). Desmoglein-1 is a calcium-binding transmembrane glycoprotein component of desmosomes in vertebrate epithelial cells. One theory is that this disease is caused by Th2 cells that induce the production of Dsg-specific autoantibodies. Allow the blood to clot at room temperature (20-25° C) and separate as soon as possible to limit hemolysis. Interestingly, mutations in desmoglein-2 have variable penetrance and heterogeneity (Pilichou et al., 2006). Skin fragility ectodermal dysplasia syndrome. Table 1. Adhesion by desmosomes is mediated by distinct members of the cadherin superfamily. Occurs mainly in the patients suffering from lymphoid malignancies, thymomas and poorly differentiated sarcomas. Desmosomal cadherins and associated intracellular proteins orchestrate the assembly of desmosomal plaques [54–57], and are expressed in a cell type- or differentiation-specific manner [58, 59]. Human disease associated with desmosomal components, Tak W. Mak, Mary E. Saunders, in The Immune Response, 2006. Do not use heat-inactivated serum as this affects test results. There are two classes of desmosomal cadherins, Arrhythmogenic right ventricular cardiomyopathy (ARVC). Acharya, A.S. Yap, in Encyclopedia of Cell Biology, 2016. Here, we identify Desmoglein 1 (Dsg1) as a novel interaction partner for SdrD. Involved in the interaction of plaque proteins and intermediate filaments mediating cell-cell … In the skin, autoimmune skin-blistering diseases such as Pemphigus vulgaris or foliaceus are caused by desmosome disruption through autoantibodies [60]. HLA-DRB1∗04:02 has been found associated with PV in Jewish populations, whereas HLA-DQB1∗05:03, HLA-DRB1∗14:04 and HLA-DRB1∗14:01 have been found associated in non-Jewish populations (67).
