  1. 1. Kallikrein-related peptidases in human epidermis : studies on activity, regulation, and function

    Författare :Kristina Stefansson; Torbjörn Egelrud; Maria Brattsand; Mona Ståhle; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; desquamation; epidermis; stratum corneum; kallikrein-related peptidase; KLK; serine protease inhibitors; Dermatology and venerology; Dermatologi och venerologi;

    Sammanfattning : Introduction. The outermost layer of the epidermis, the stratum corneum (SC), plays a fundamental role in our defense against microorganisms, chemicals, and dehydration. The SC is composed of tightly packed keratinized skin cells, corneocytes. For a functioning skin it is essential that corneocytes are constantly shed (desquamated). LÄS MER

  3. 2. DNA Damage Response of Normal Epidermis in the Clinical Setting of Fractionated Radiotherapy : Evidence of a preserved low-dose hypersensitivity response

    Författare :Fredrik Qvarnström; Ingela Turesson; Gunilla Enblad; Mats Harms-Ringdahl; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA damage response; low-dose hypersensitivity; dose response; normal tissue; epidermis; keratinocyte; fractionated radiotherapy; DNA double strand break; DSB; foci; γH2AX; 53BP1; checkpoint; p21; apoptosis; mitosis; Oncology; Onkologi; Oncology; onkologi;

    Sammanfattning : Investigations of DNA damage response (DDR) mechanisms in normal tissues have implications for both cancer prevention and treatments. The accumulating knowledge about protein function and molecular markers makes it possible to directly trace and interpret cellular DDR in a tissue context. LÄS MER

  4. 3. In vitro Studies of Genodermatoses Affecting Cytoskeletal Integrity and Lipid Processing in Human Epidermis : Pathogenic Mechanisms and Effects of Retinoid Therapy

    Författare :Hao Li; Hans Törmä; Anders Vahlquist; Mikael Ivarsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Congenital Ichthyosiform Erythroderma; Epidermolytic Hyperkeratosis; Ceramides; Keratins; Retinoids; Molecular Probe Techniques; Transglutaminases; Lipoxygenases; Fatty Acid Transporter Proteins; Keratinocytes; Epidermis; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Autosomal dominant epidermolytic ichthyosis (EI) is a rare disease characterized by intra-epidermal blistering due to mutations in either of two keratin genes, KRT1 and KRT10, expressed by suprabasal keratinocytes. Autosomal recessive congenital ichthyosis (ARCI) is a non-blistering, hyperkeratotic disease caused by mutations in one of the following genes: ABCA12, ALOX12B, ALOXE3, TGM1, CYP4F22, NIPAL4 and SLC27A4, which are all essential for skin barrier homeostasis.

  5. 4. Retinoic Acid Metabolism Blocking Agents and the Skin : In vivo and in vitro Studies of the Effects on Normal and Diseased Human Epidermis

    Författare :Elizabeth Pavez Loriè; Anders Vahlquist; Hans Törmä; Marie Virtanen; Helen Håkansson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CYP; CYP26; retinoids; vitamin A; RAMBA; metabolism; keratinocyte; epidermis; retinoid regulated genes; Dermatology and venerology; Dermatologi och venerologi;

    Sammanfattning : Retinoic Acid Metabolism Blocking Agents (RAMBAs) increase the endogenous levels of all-trans retinoic acid (RA) by inhibiting CYP26 enzymes. Thus they are believed to mimic the effects of retinoid treatment. Their mechanism of action and effects on vitamin A metabolism in keratinocytes are however uncertain. LÄS MER

  7. 5. Epidermal Reactions to Injury with Implications for Innate Immunity

    Författare :Markus Roupé; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Innate immunity; epidermis; Wound healing; interleukin-8; Antimicrobial peptides;

    Sammanfattning : Abstract The epidermis is one of our primary interfaces towards the external milieu. Following injury, the physical barrier function of the skin is destroyed and the epidermis is left vulnerable to microbial invasion. LÄS MER
