Department of Dermatology, Kaohsiung Medical University Hospital, Kaohsiung Medical University, Kaohsiung 807378, Taiwan.

Autoimmune bullous skin disorders are a group of disorders characterized by the formation of numerous blisters and erosions on the skin and/or the mucosal membrane, arising from autoantibodies against the intercellular adhesion molecules and the structural proteins. They can be classified into intraepithelial or subepithelial autoimmune bullous dermatoses based on the location of the targeted antigens. These dermatoses are extremely debilitating and fatal in certain cases, depending on the degree of cutaneous and mucosal involvement. Read More

The Immunogenetics of Autoimmune Blistering Diseases.

Adv Exp Med Biol 2022 ;1367:173-212

Division of Dermatology, Rush University Medical Center, Chicago, USA.

Dermatological conditions constituting the group of autoimmune blistering diseases (AIBD) are characterized by loss of immunotolerance and humoral, as well as cellular, autoimmune responses that result in the development of bullae and erosions on the skin and mucous membranes. AIBDs are broadly categorized into pemphigus and pemphigoid classes with several distinct subtypes amongst them. Advances in genetics have allowed for the study and identification of alleles, and even single nucleotide polymorphisms, that harbor increased susceptibility or confer protection for the development of these conditions.

A gene-centric approach to biomarker discovery identifies transglutaminase 1 as an epidermal autoantigen.

Proc Natl Acad Sci U S A 2021 12;118(51)

Center for Molecular Medicine, Department of Medicine (Solna), Karolinska Institutet, Stockholm 171 76, Sweden.

Autoantigen discovery is a critical challenge for the understanding and diagnosis of autoimmune diseases. While autoantibody markers in current clinical use have been identified through studies focused on individual disorders, we postulated that a reverse approach starting with a putative autoantigen to explore multiple disorders might hold promise. We here targeted the epidermal protein transglutaminase 1 (TGM1) as a member of a protein family prone to autoimmune attack. Read More

Plectin in Skin Fragility Disorders.

Cells 2021 10 14;10(10). Epub 2021 Oct 14.

Department of Dermatology, Faculty of Medicine, Medical Center-University of Freiburg, 79104 Freiburg, Germany.

Plectin is a multi-faceted, 500 kDa-large protein, which due to its expression in different isoforms and distinct organs acts diversely as a cytoskeletal crosslinker and signaling scaffold. It functions as a mediator of keratinocyte mechanical stability in the skin, primarily through linking intermediate filaments to hemidesmosomes. Skin fragility may occur through the presence of mutations in the gene encoding for plectin, , or through the presence of autoantibodies against the molecule. Read More

Comprehensive review on the pathophysiology, clinical variants and management of pemphigus (Review).

Exp Ther Med 2021 Nov 20;22(5):1335. Epub 2021 Sep 20.

Department of Oral Medicine and Oral Dermatology, 'Grigore T. Popa' University of Medicine and Pharmacy, 700115 Iași, Romania.

Pemphigus represents a group of chronic inflammatory disorders characterized by autoantibodies that target components of desmosomes, leading to the loss of intercellular adhesion between keratinocytes and causing intraepithelial blistering. The pemphigus group consists of four main clinical types with several variants: pemphigus vulgaris (with pemphigus vegetans and pemphigus herpetiformis as variants), pemphigus foliaceus, paraneoplastic pemphigus and IgA pemphigus (with two clinical variants: intraepidermal neutrophilic IgA dermatosis and subcorneal pustular dermatosis). Genetic factors are involved in the pathogenesis, with HLA-DR4 (DRB1*0402) and HLA-DRw6 (DQB1*0503) allele more common in patients with pemphigus vulgaris, HLA class II DRB1*0344 and HLA Cw*1445 correlated with paraneoplastic pemphigus, and HLA-DRB1*04:01, HLA-DRB1*04:06, HLA-DRB1*01:01, HLA-DRB1*14, associated with a higher risk of developing pemphigus foliaceus.
