    Anti-Thyroid Peroxidase Reactivity Is Heightened in Pemphigus Vulgaris and Is Driven by Human Leukocyte Antigen Status and the Absence of Desmoglein Reactivity.
    Front Immunol 2018 5;9:625. Epub 2018 Apr 5.
    Department of Dermatology, Jacobs School of Medicine and Biomedical Sciences, Buffalo, NY, United States.
    Pemphigus vulgaris (PV) belongs to an autoimmune disease cluster that includes autoimmune thyroid disease (AITD), suggesting common mechanisms driving autoimmune susceptibility. Our group has shown that PV patients exhibit significant reactivity to AITD-related anti-thyroid peroxidase (anti-TPO), and anti-TPO antibodies affect signaling pathways in keratinocytes similar to anti-desmoglein (Dsg) 3 antibodies. To further assess the relevance of anti-TPO reactivity in PV, we analyzed anti-TPO levels in 280 PV and 167 healthy control serum samples across a comprehensive set of variable and static parameters of disease activity and etiopathogenesis.

    Atomic Force Microscopy Provides New Mechanistic Insights into the Pathogenesis of Pemphigus.
    Front Immunol 2018 28;9:485. Epub 2018 Mar 28.
    Institute of Anatomy, Faculty of Medicine, Ludwig-Maximilians-Universität München, Munich, Germany.
    Autoantibodies binding to the extracellular domains of desmoglein (Dsg) 3 and 1 are critical in the pathogenesis of pemphigus by mechanisms leading to impaired function of desmosomes and blister formation in the epidermis and mucous membranes. Desmosomes are highly organized protein complexes which provide strong intercellular adhesion. Desmosomal cadherins such as Dsgs, proteins of the cadherin superfamily which interact their extracellular domains in Ca-dependent manner, are the transmembrane adhesion molecules clustered within desmosomes.

    Soluble Fas Ligand Is Essential for Blister Formation in Pemphigus.
    Front Immunol 2018 26;9:370. Epub 2018 Feb 26.
    Laboratory of Cutaneous Biology, Department of Surgical, Medical, Dental and Morphological Sciences, University of Modena and Reggio Emilia, Modena, Italy.
    Pemphigus is a blistering disease characterized by pemphigus autoantibodies (PVIgG) directed mostly against desmogleins (Dsgs), resulting in the loss of keratinocyte adhesion (acantholysis). Yet, the mechanisms underlying blister formation remain to be clarified. We have shown previously that anti-Fas ligand (FasL) antibody (Ab) prevents PVIgG-induced caspase-8 activation and Dsg cleavage in human keratinocytes, and that sera from pemphigus patients contain abnormally increased levels of FasL.

    Medical Institute of Ministry of Interior (MVR-Sofia), Department of Dermatology, Venereology and Dermatologic Surgery, Sofia, Bulgaria.
    It is well-established that drugs could be leading cause of occurrence of numerous diseases, including pemphigus, being either inducer or triggering factor of the autoimmunity. Despite medications, it should be kept in mind that chronic or acute infections are also capable of being a trigger in various types of cutaneous eruptions, including pemphigus. The rapidly obtained and uncompleted history for accompanied medication leads to general mistakes in the subsequent treatment approach, as the first step in such cases is discontinuation of the drug-inductor.
