N2 - Three desmoglein (Dsg) isoforms are expressed in a differentiation- specific fashion in the epidermis, with Dsg2 being basal, Dsg3 (pemphigus vulgaris antigen) basal and spinous, and Dsg1 (pemphigus foliaceus antigen) predominately granular. To better understand the mechanism(s) regulating Dsg isoform expression, we examined the expression pattern of Dsg1, Dsg2, and Dsg3 in normal human epidermal keratinocytes (NHEKs), the immortalized, nontumorigenic HaCaT cell line, and several squamous cell carcinoma cell lines (SCC-9, SCC-12F, SCC-13, and SCC-25). In all cells, the accumulation of high Dsg protein levels required calcium and was not observed in low calcium (0.050.07 ...

TY - JOUR. T1 - Neonatal pemphigus vulgaris. T2 - IgG4 autoantibodies to desmoglein 3 induce skin blisters in newborns. AU - Parlowsky, Thomas. AU - Welzel, Julia. AU - Amagai, Masayuki. AU - Zillikens, Detlef. AU - Wygold, Thorsten. PY - 2003/4/1. Y1 - 2003/4/1. N2 - We report a case of neonatal pemphigus vulgaris presenting with skin lesions on the head, genital area, and right foot. Pemphigus vulgaris was diagnosed by the presence of circulating autoantibodies predominantly of the IgG4 subtype by indirect immunofluorescence microscopy and by enzyme-linked immunosorbent assay using recombinant desmoglein 3. This case demonstrates the pathogenic relevance of IgG4 autoantibodies to desmoglein 3 in the skin of neonates..

In patients with pemphigus vulgaris (PV), autoantibodies against desmoglein 3 (Dsg3) cause loss of cell-cell adhesion of keratinocytes in the basal and immediate suprabasal layers of stratified squamous epithelia. The pathology, at least partially, may depend on protease release from keratinocytes, but might also result from antibodies interfering with an adhesion function of Dsg3. However, a direct role of desmogleins in cell adhesion has not been shown. To test whether Dsg3 mediates adhesion, we genetically engineered mice with a targeted disruption of the DSG3 gene. DSG3 -/- mice had no DSG3 mRNA by RNase protection assay and no Dsg3 protein by immunofluorescence (IF) and immunoblots. These mice were normal at birth, but by 8-10 d weighed less than DSG3 +/- or +/+ littermates, and at around day 18 were grossly runted. We speculated that oral lesions (typical in PV patients) might be inhibiting food intake, causing this runting. Indeed, oropharyngeal biopsies showed erosions with histology

N2 - Pemphigus is a life-threatening blistering disorder of the skin and mucous membranes caused by pathogenic autoantibodies to desmosomal adhesion proteins desmoglein 3 (Dsg3) and Dsg1. Mechanisms of antibody pathogenicity are difficult to characterize using polyclonal patient sera. Using antibody phage display, we have isolated repertoires of human anti-Dsg mAbs as single-chain variable-region fragments (scFvs) from a patient with active mucocutaneous pemphigus vulgaris. ScFv mAbs demonstrated binding to Dsg3 or Dsg1 alone, or both Dsg3 and Dsg1. Inhibition ELISA showed that the epitopes defined by these scFvs are blocked by ...
Background: The use of saliva for the diagnosis of pemphigus vulgaris (PV) by enzyme-linked immunosorbent assay (ELISA) using desmoglein (Dsg)3 antigen has not been extensively documented, nor has the detection of serum IgA antibodies to Dsg3. Objectives: (i) To establish whether whole saliva might provide a suitable alternative to serum for diagnosing and monitoring PV; (ii) to investigate whether anti-Dsg3 IgA antibodies can be detected in serum and saliva and (iii) to establish whether there is an association between serum or saliva anti-Dsg3 antibodies and disease severity. Methods: Precoated Dsg3 ELISA plates were used to test serum and/or saliva for IgG and IgA antibodies. Matched serum and whole saliva samples were collected from 23 patients with PV, 17 healthy subjects and 19 disease controls. All patients with PV, disease controls and six healthy controls provided matched parotid saliva. Results: Whole saliva IgG antibodies to Dsg3 were detected in 14 of 23 patients (61%) and serum IgG ...

Chapel Hill, North Carolina. Autoimmune blistering skin diseases first were identified in companion animals twenty five years ago, with the description of two dogs affected with pemphigus vulgaris (PV). Two years later, the first cases of pemphigus foliaceus (PF) were recognized in canine patients. These two diseases represent the main forms of animal pemphigus being diagnosed by veterinarians.. Surprisingly, whereas the main form of pemphigus affecting human individuals is pemphigus vulgaris (PV), this entity is extremely rare in dogs with less than 50 cases being reported in veterinary medical journals. This deep pemphigus variant also has been recognized, albeit very sporadically, in rare cats and horses.. ...

Corneal involvement is a rare complication in patients with pemphigus vulgaris. Severe corneal involvement has never been reported except in the case of a 56 year old man with severe ocular involvement including conjunctivitis, corneal ulceration, and perforation despite immunosuppressive therapy.4 Although a causative organism was not isolated, the authors suggested that the complications were due to an infectious agent.. Two mechanisms have been suggested to cause the corneal erosion-bacteria or other pathogenic organisms that infect the cornea because of the epithelial defect and tear film disorder brought on by the corticosteroid and immunosuppressive therapy. Although the culture obtained from right ocular discharge before starting ofloxacin ointment showed a negative result, we could not deny the bacterial infection. We did not perform a bacterial or viral culture or polymerase chain reaction examinations using a corneal sample.. The second mechanism is an autoimmune mechanism against one ...
The purpose of this study is to explore a new medication for the skin disease termed pemphigus. Our specific aim is to determine whether the use of sirolimus will allow for a decrease in the dosage or possibly eliminate the need for corticosteroids, which so far is the only type of drug that can control this disease.. Pemphigus is an autoimmune disease characterized by blistering, caused by autoantibodies against certain cells in the skin. This disease most commonly occurs in individuals ages 50 and older, and it presents as painful shallow erosions and/or blisters in the mouth and/or skin. Pemphigus is very painful and uncomfortable, associated with impaired quality of life and significant morbidity. Severe or untreated cases of pemphigus can become fatal if the involved surface area becomes large enough to cause dehydration and/or infection. The first line of therapy, and the standard of care, for pemphigus remain to be systemic corticosteroids. However, corticosteroids have many known side ...

Retinoic acid (RA) in the steady state enhances induction of Foxp3+ regulatory T (Treg) cells and inhibits differentiation of Th1 and Th17 cells, thereby maintaining tolerance, but can in inflammatory conditions promote effector Th1 and Th17 cells that mediate inflammation. IL‐17‐producing γδ T cells have recently been shown to have a major pathogenic role in autoimmune diseases. Here, we examined the immunomodulatory effects of RA on γδ T cells. We found that RA had a dramatic suppressive effect on IL‐17A and IL‐17F production by γδ T cells stimulated with IL‐1β and IL‐23. RA suppressed RORγt, IL‐1R and IL‐23R expression in γδ T cells. Treatment of mice with RA suppressed IL‐17 production by γδ T cells in vivo. Furthermore, treatment of T cells with RA attenuated their ability to induce disease in experimental autoimmune encephalomyelitis (EAE), a murine model for multiple sclerosis. This was associated with a reduction in the number of central nervous ...

In the current study, we found that the function of AH associated DE gene DSG1 (up-regulated in cows fed AH, compared with those fed CS and RS) was enriched under the ion-binding function as well as was associated with tight junctions. This gene encodes a member of the desmoglein protein subfamily which has been reported to be involved in epithelial cell proliferation in bovine epidermis and tongue papillae [36]. It has been speculated that ion binding in the rumen may be attributed to the Na+-K--ATPase transport system for nutrient absorption [37]. Na+-K- pumps are predominately localized to the innermost living cell layers of the stratum spinosum and the stratum germinativum [38]. Increased VFAs absorption by greater Na+-K--ATPase activity could prevent possible disturbance of epithelial functions (transport and barrier functions) [39]. The higher amount of VFAs and the greater expression of DSG1 in cows fed AH diet indicates likely more nutrient transport through RE when animals fed AH ...

Background Paraneoplastic pemphigus (PNP) is a devastating autoimmune blistering disease, involving mucocutaneous and internal organs, and associated with underlying neoplasms. PNP is characterized by the production of autoantibodies targeting proteins of the plakin and cadherin families involved in maintenance of cell architecture and tissue cohesion. Nevertheless, the identity of an antigen of Mr 170,000 (p170), thought to be critical in PNP pathogenesis, has remained unknown. Methodology/Principal Findings Using an immunoprecipitation and mass spectrometry based approach, we identified p170 as alpha-2-macroglobuline-like-1, a broad range protease inhibitor expressed in stratified epithelia and other tissues damaged in the PNP disease course. We demonstrate that 10 PNP sera recognize alpha-2-macroglobuline-like-1 (A2ML1), while none of the control sera obtained from patients with bullous pemphigoid, pemphigus vulgaris, pemphigus foliaceus and normal subjects does.

Background:Pemphigus is a life-threatening, autoimmune blistering disease, mediated by IgG autoantibodies. The aim of our study was to assess the usefulness of a new enzyme-linked immunosorbent assay (ELISA) in detecting circulating pemphigus autoantibodies, and to compare its sensitivity and specificity with the indirect immunofluorescence (IIF) test. We also established the frequency of occurrence of pemphigus autoantibodies in relatives of our patients.Material/Methods:IIF and ELISA tests were performed in 24 patients with pemphigus vulgaris, 13 with pemphigus foliaceus, 56 healthy relatives, and 50 controls, selected according to sex and age.Results:The obtained results revealed high specificity and sensitivity of ELISA, comparable to the IIF test, especially in patients who were in the active stage of the disease. We also showed that the profile of anti-Dsg 1 and/or anti-Dsg 3 autoantibodies is associated with the clinical variant of pemphigus. The frequency of occurrence of pemphigus ...

Pemphigus foliaceus is one of the most common autoimmune diseases in dogs, leading to autoantibodies to desmoglein I and finally to pustule and crust formation. Immunosuppressive therapy is mandatory in this disease - but does it always have to be given for the rest of the life? An interesting, rarely discussed question!

Pemphigus describes a group of autoimmune blistering diseases that involve the epidermal surfaces of the skin, mucosa, or both. There are 3 broad categories: pemphigus vulgaris (PV), pemphigus foliaceus (PF), and paraneoplastic pemphigus (PNP). Pemphigus is mediated by an autoantibody that binds a specific component of the desmosomal plaque. The desmosomal plaque holds the keratinocytes of the skin and mucosa together. ...

RESULTS: Thirty-five patients were included. Clinical phenotypes were: mucosal in 17 patients; mucous-cutaneous in 11; and cutaneous in 7. The status of anti-Dsg1 autoantibodies was significantly related to the cutaneous and mucous-cutaneous phenotypes both at diagnosis and after 6 months. The status of anti-Dsg3 autoantibodies was significantly related to the mucosal and mucous-cutaneous phenotypes only at first evaluation. No significant correlations were found between disease activity and the status of autoantibodies. No significant variations of autoantibody levels (between first and second sample) were found with regard to different therapies, except for the variation of anti-Dsg1 autoantibodies in one patient treated with systemic steroids and methotrexate ...
