Background: Filaggrin-2 (FLG2) and hornerin (HRNR) are members of the S100 fused-type protein family, which share many properties with filaggrin (FLG). A previous study demonstrated that the expression of FLG2 was significantly decreased in psoriatic skin relative to that in normal skin. In contrast, the HRNR expression in psoriatic skin varied among studies.

Narrow-band UVB (NB-UVB) therapy at a wavelength of 311 nm is often used to treat mycosis fungoides (MF). However, we occasionally encounter cases of erythema induced by low doses of NB-UVB, known as an abnormal light reaction (ALR). We investigated the incidence of ALR in patients with MF and the association between ALR and clinical and laboratory findings.

Bullous pemphigoid (BP) is a rare autoimmune blistering disease that primarily affects elderly individuals. Based on the Bullous Pemphigoid Disease Area Index (BPDAI) severity assessment, immunosuppressive drugs are recommended for severe cases that fall within the more than moderate classes. Sarcopenia, which is characterized by decreased skeletal muscle mass and function in elderly patients, is a progressive and widespread skeletal muscle disease.

Pemphigus vegetans is a rare type of pemphigus characterized by vegetative lesions primarily localized to the intertriginous area. Despite its unique clinical presentation, the underlying pathomechanism remains unclear owing to the rarity of the disease. We report a case of pemphigus vegetans with antibodies against desmoglein 1 and desmocollins 1-3.

Cornulin (CRNN) and repetin (RPTN) belong to the fused-type S100 protein family. Although these proteins have been reported to be expressed in the granular layer of the epidermis and have been suggested to be associated with barrier formation in the epidermis, their exact function remains unclear. This study examined the effects of ultraviolet B (UVB) irradiation on CRNN and RPTN expression in human skin xenotransplantation.

PTPRD, a well-established tumor suppressor gene, encodes the protein tyrosine phosphatase-type D. This protein consists of three immunoglobulin-like (Ig) domains, four to eight fibronectin type 3 (FN) domains, a single transmembrane segment, and two cytoplasmic tandem tyrosine phosphatase domains. PTPRD is known to harbor various cancer-associated point mutations.

Article Synopsis
  • Vitiligo is a skin condition marked by depigmented patches that negatively affect patients’ quality of life, and its causes include genetic and environmental factors, with microorganisms being a less-studied aspect.
  • The study aimed to analyze bacterial and fungal populations in the skin of vitiligo patients to understand their potential role in the condition's development.
  • Results indicated a distinctive composition of microorganisms in vitiligo-affected skin, revealing variations in bacterial and fungal diversity that could influence disease activity and offer insights for personalized treatment strategies.*

Article Synopsis
  • Researchers studied the filaggrin-like protein hornerin (HRNR) to understand its role in atopic dermatitis (AD) by examining skin lesions from seven patients.
  • HRNR was present in chronic AD lesions but absent in acute ones, hinting at its potential involvement in the skin's response to chronic inflammation.
  • The study also found HRNR in other skin conditions with hyperkeratosis, suggesting that HRNR may have a distinct role in skin cell growth and development, particularly in cornification.

Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe cutaneous adverse reaction involving multiorgan failure, with a complex interaction of various drugs, human herpesvirus reactivation and immune abnormalities suggested as the aetiology. We herein present the case of a 70-year-old man with a one-week history of fever, facial oedema, erythematous macules and purpura on his trunk and extremities. He had anti-TIF1γ antibody-positive dermatomyositis and was treated with prednisolone sodium succinate (20 mg/day).

A 53-year-old man was presented with refractory panniculitis on the left upper arm that had persisted for 10 months. The patient was diagnosed with lupus profundus, wherein oral glucocorticoid therapy was initiated. Four months prior, ulceration was observed in the same area.

Anti-p200 pemphigoid is a rare subepidermal blistering disease showing immunoglobulin G (IgG) autoantibodies reactive with a 200-kDa protein. In most patients, serum IgG antibodies react with laminin γ1. The diagnosis of anti-p200 pemphigoid is occasionally difficult, mainly due to the lack of standardized tests.

Atopic dermatitis (AD) is a chronic inflammatory skin disorder with elevated interleukin (IL)-4 and IL-13 signatures and extensive barrier dysfunction, which is correlated with the downregulation of filaggrin (FLG). FLG is a member of the S100 fused-type protein family and this family also includes cornulin (CRNN), filaggrin-2 (FLG2), hornerin (HRNR) repetin (RPTN), trichohyalin (TCHH) and trichohyalin-like 1 (TCHHL1). The present study aimed to examine the effects of IL-4 and IL-13 and the downregulation of FLG on the expression of S100 fused-type proteins using a three-dimensional (3D) AD skin model by immunohistochemical study and quantitative polymerase chain reaction.

Hypereosinophilic syndrome (HES) is a heterogeneous group of diseases, characterized by persistent hypereosinophilia and end-organ damage. The FIP1L1-PDGFRA (F/P) fusion gene is found in 3-25% of patients with HES and is an oncogenic driver of myeloid neoplasms with clonal eosinophilia. Although cutaneous symptoms are the most common type of symptom in patients who have F/P fusion gene-positive HES (F/P HES), histological reports are limited.

9,10-Phenanthrenequinone (9,10-PQ), a polycyclic aromatic hydrocarbon that is present in air pollutants, such as diesel exhaust gas and PM2.5, causes the production of excess reactive oxygen species. 9,10-PQ was recently shown to induce the activation of epidermal growth factor receptor (EGFR) by inhibiting protein tyrosine phosphatase 1B.
