    The "Kelch" Surprise: KLHL24, a New Player in the Pathogenesis of Skin Fragility.
    J Invest Dermatol 2017 Jun;137(6):1211-1212
    Department of Dermatology, Medical Center-University of Freiburg, Freiburg, Germany. Electronic address:
    A new protein, kelch-like 24, has recently been associated with a distinct subtype of epidermolysis bullosa simplex, a heterogeneous group of disorders associated with mechanical fragility of epidermal keratinocytes. All mutations involve the translation initiation codon and lead to a degradation-resistant N-terminally truncated kelch-like 24. Kelch-like 24 appears to be involved in the turnover of intermediated filaments, in particular of keratin 14, in keratinocytes. Read More

    Pathomechanisms of Altered Wound Healing in Recessive Dystrophic Epidermolysis Bullosa.
    Am J Pathol 2017 Apr 28. Epub 2017 Apr 28.
    Laboratory of Molecular and Cell Biology, Istituto Dermopatico dell'Immacolata-IRCCS, Roma, Italy. Electronic address:
    Individuals with recessive dystrophic epidermolysis bullosa (RDEB), a rare genetic skin disease, carry mutations in the COL7A1 gene that codes for type VII collagen, an extracellular matrix component of the basement membrane zone forming the anchoring fibrils. As a consequence, RDEB individuals manifest unremitting skin blistering that evolves into chronic wounds, inflammation, and fibrosis. These features play a central role in the development of more severe disease complications, such as mitten deformities of hands and feet and aggressive epithelial cancers. Read More

    Department of Dermatology, Kurume University School of Medicine, Kurume University Institute of Cutaneous Cell Biology, Kurume, Japan.
    In this study, we generated a new set of monoclonal antibodies (mAbs) to bovine and human type VII collagen (COL7) by immunizing mice with bovine cornea-derived basement membrane zone (BMZ) fraction. The four mAbs, tentatively named as COL7-like mAbs, showed speckled subepidermal staining in addition to linear BMZ staining of normal human skin and bovine cornea, a characteristic immunofluorescence feature of COL7, but showed no reactivity with COL7 by in vitro biochemical analyses. Taking advantage of the phenomenon that COL7-like mAbs did not react with mouse BMZ, we compared immunofluorescence reactivity between wild-type and COL7-rescued humanized mice and found that COL7-like mAbs reacted with BMZ of COL7-rescued humanized mice.
