Fixing the skin barrier: past, present and future - man and dog compared.
Abstract Skin barrier dysfunction exists in both human and canine atopic dermatitis, leading to increased water loss and potentially facilitating allergen penetration and sensitization. Both lipid (e.g. ceramides) and protein (e.g. filaggrin) abnormalities have been described. Some are genetically inherited (e.g. filaggrin mutations are one of the major risk factors in humans) and some are secondary and linked to inflammation. In humans, numerous studies have shown efficacy of emollients and moisturizers in barrier restoration, and this approach has been for years the mainstay of therapy. Recently, this strategy ha...

Stem cell therapy in veterinary dermatology.
Abstract Background - Adult stem cells come from many sources and have the capacity to differentiate into many cell types, including those of the skin. The most commonly studied stem cells are those termed mesenchymal stem cells (MSCs), which are easily isolated from bone marrow and adipose tissue. Mesenchymal stem cells are known to produce a wide array of cytokines that modulate the regeneration process. The ease of collection, propagation and use of these MSCs in therapy of traumatic, ischaemic and immune-mediated skin conditions is emerging. Approach and evidence - In traumatic and ischaemic skin damage, ...

The canine and feline skin microbiome in health and disease.
Abstract The skin harbours a diverse and abundant, yet inadequately investigated, microbial population. The population is believed to play an important role in both the pathophysiology and the prevention of disease, through a variety of poorly explored mechanisms. Early studies of the skin microbiota in dogs and cats reported a minimally diverse microbial composition of low overall abundance, most probably as a reflection of the limitations of testing methodology. Despite these limitations, it was clear that the bacterial population of the skin plays an important role in disease and in changes in response to both i...

Ulcerated and nonulcerated nontuberculous cutaneous mycobacterial granulomas in cats and dogs.
Abstract Background - Mycobacterial granulomas of the skin and subcutis can be caused by one of a number of pathogens. This review concentrates on noncultivable species that cause diseases characterized by focal granuloma(s), namely leproid granuloma (in dogs) and feline leprosy (in cats). Clinically indistinguishable lesions can be caused by tuberculous organisms (Mycobacterium bovis and Mycobacterium microti) and members of the Mycobacterium avium complex. Rapidly growing mycobacterial species that cause infection of the subcutaneous panniculus associated with draining tracts are not discussed. Disease caused ...

Advances in the management of skin cancer.
Abstract Skin cancer is one of the most commonly diagnosed cancers in the world today in both humans and our pet population. Advances in molecular techniques are now affording us an opportunity to develop therapeutics targeted at specific cancer-related cellular pathways. However, despite progress in conventional treatments, such as chemotherapy and radiation, and the new targeted therapies, some cancers, such as melanoma and cutaneous lymphoma, continue to cause significant mortality and morbidity. This short synopsis is not complete but is aimed at providing an insight into current advanced treatments and horizon...

The contribution of stem cells to epidermal and hair follicle tumours in the dog.
Conclusions and clinical importance - Our results show that K15 can be a reliable marker for investigating the role of stem cells in hair follicle tumours of the dog, while nestin was judged to be a nonoptimal marker. Furthermore, our study suggests that hair follicle stem cells are present in the bulge region of hair follicles and could possibly play a role in tumourigenesis of canine tumours originating from this portion of the follicle, namely trichoblastomas, tricholemmomas and trichoepitheliomas. The loss of K15 expression in squamous cell carcinomas compared with normal skin suggests that this event could be impor...

Turn the Other Cheek
A 56-year-old man underwent two skin biopsies to evaluate facial lesions. The first biopsy was diagnostic for squamous cell carcinoma (SCC); the site was documented as “left cheek” in the health record. The second biopsy was an atrophic solar keratosis (a benign finding); the site was documented as “left inferior orbit.” The primary care physician referred the patient to a dermatologic surgeon. The referral included a diagram of a face with the SCC biopsy site marked by an “X” on the left cheek. The pathology report included a description of the anatomic location that said “left cheek.”

The Pathogenesis and Genetics of Psoriasis.
Abstract Psoriasis vulgaris and psoriatic arthritis are interrelated disorders with an important genetic component. While linkage studies have identified several candidate loci and genes, only recent technological advances and extensive genome-wide association studies have provided robust evidence of associations between psoriasis and several genes inside and outside the major histocompatibility complex. Most of these genes can be incorporated into an integrated pathogenic model of psoriatic disease comprising distinct signaling networks affecting skin barrier function (LCE3, DEFB4, GJB2), innate immune responses i...

Photosensitivity and photodynamic events in black, red and blue tattoos are common: A ‘Beach Study’
ConclusionComplaints such as swelling, itching, stinging, pain and redness are common, predominantly in black and red tattoos, but also frequent in blue tattoos, thus, not confined to one specific colour or chemical entity or class of pigment. Symptoms may switch on and off in seconds, typically not of the weal‐and‐flare type. Photochemical reactions to pigment or pigment‐breakdown products in situ in the skin with induction of reactive oxygen species (ROS) is presumed to be one causative mechanism. Another possible mechanism especially relevant in black may be induction of ROS due to effects of aggregation of carbon...

Keratinocyte Overexpression of IL-17C Promotes Psoriasiform Skin Inflammation.
Abstract IL-17C is a functionally distinct member of the IL-17 family that binds IL-17 receptor E/A to promote innate defense in epithelial cells and regulate Th17 cell differentiation. We demonstrate that IL-17C (not IL-17A) is the most abundant IL-17 isoform in lesional psoriasis skin (1058 versus 8 pg/ml; p < 0.006) and localizes to keratinocytes (KCs), endothelial cells (ECs), and leukocytes. ECs stimulated with IL-17C produce increased TNF-α and KCs stimulated with IL-17C/TNF-α produce similar inflammatory gene response patterns as those elicited by IL-17A/TNF-α, including increases in IL-17C, TNF-α, IL...

Will PAXgene substitute formalin? A morphological and molecular comparative study using a new fixative system
Conclusions The switch from formalin to PAXgene fixation would require a re-evaluation of immunohistochemical markers and staining procedures originally developed for FFPE tissues. Our data demonstrate that PAXPE fixation offers some advantages concerning molecular analysis. However, these advantages would not justify substituting formalin fixation in any routine pathology laboratory.

Old King Coal — molecular mechanisms underlying an ancient treatment for atopic eczema
Traditional remedies for common disorders have been known for centuries, but insight into their mechanism of action is often limited. In this issue of the JCI, Joost Schalkwijk’s research group at the Radboud University Nijmegen Medical Centre in The Netherlands advances our understanding of why topical coal tar is an effective treatment for atopic dermatitis (AD), both rationalizing the use of this traditional medicine, and providing the scientific basis for new therapeutic approaches.

Coal tar induces AHR-dependent skin barrier repair in atopic dermatitis
Topical application of coal tar is one of the oldest therapies for atopic dermatitis (AD), a T helper 2 (Th2) lymphocyte–mediated skin disease associated with loss-of-function mutations in the skin barrier gene, filaggrin (FLG). Despite its longstanding clinical use and efficacy, the molecular mechanism of coal tar therapy is unknown. Using organotypic skin models with primary keratinocytes from AD patients and controls, we found that coal tar activated the aryl hydrocarbon receptor (AHR), resulting in induction of epidermal differentiation. AHR knockdown by siRNA completely abrogated this effect. Coal tar restored ...

Nephronectin binds to heparan sulfate proteoglycans via its MAM domain.
Abstract Nephronectin is a basement membrane protein comprising five N-terminal epidermal growth factor (EGF)-like repeats, a central linker segment containing an Arg-Gly-Asp (RGD) motif and a C-terminal meprin-A5 protein-receptor protein tyrosine phosphatase μ (MAM) domain. Nephronectin has been shown to interact with α8β1 integrin through the central linker segment, but its interactions with other molecules remain to be elucidated. Here, we examined the binding of nephronectin to a panel of glycosaminoglycan (GAG) chains. Nephronectin bound strongly to heparin and chondroitin sulfate (CS)-E and moderately to h...

Dermatan 4-O-sulfotransferase1 ablation accelerates peripheral nerve regeneration.
Abstract Chondroitin sulfate (CS) and dermatan sulfate (DS) proteoglycans are major components of the extracellular matrix implicated in neural development, plasticity and regeneration. While it is accepted that CS are major inhibitors of neural regeneration, the contributions of DS to regeneration have not been assessed. To enable a novel approach in studies on DS versus CS roles during development and regeneration, we generated a mouse deficient in the dermatan 4-O-sulfotransferase1 (Chst14(-/-)), a key enzyme in the synthesis of iduronic acid-containing modules found in DS but not CS. In wild-type mice, Chst14 i...

[Seminar] Pemphigoid diseases
Pemphigoid diseases are a group of well defined autoimmune disorders that are characterised by autoantibodies against structural proteins of the dermal–epidermal junction and, clinically, by tense blisters and erosions on skin or mucous membranes close to the skin surface. The most common of these diseases is bullous pemphigoid, which mainly affects older people and the reported incidence of which in Europe has more than doubled in the past decade. Prognosis and treatments vary substantially between the different disorders and, since clinical criteria are usually not sufficient, direct immunofluorescence microscopy of a ...

Cutaneous noradrenaline measured by microdialysis in complex regional pain syndrome during whole-body cooling and heating.
Abstract Complex regional pain syndrome (CRPS) is characterised by autonomic, sensory, and motor disturbances. The underlying mechanisms of the autonomic changes in CPRS are unknown. However, it has been postulated that sympathetic inhibition in the acute phase with locally reduced levels of noradrenaline is followed by an up-regulation of alpha-adrenoceptors in chronic CRPS leading to denervation supersensitivity to catecholamines. This exploratory study examined the effect of cutaneous sympathetic activation and inhibition on cutaneous noradrenaline release, vascular reactivity, and pain in CRPS patients and in h...

Pemphigus vulgaris in a Welsh pony stallion: case report and demonstration of antidesmoglein autoantibodies.
CONCLUSIONS AND CLINICAL IMPORTANCE: Pemphigus vulgaris is rarely diagnosed in equids. We describe a case that was substantiated by the demonstration of anti-Dsg3 IgG. Response to treatment was poor, with the best response to high doses of prednisolone. Equine pemphigus vulgaris is likely to carry a poor prognosis and if there is no response to treatment, humane euthanasia is warranted. PMID: 23347322 [PubMed - as supplied by publisher]

Arsenic exposure affects millions of people worldwide, causing substantial mortality and morbidity from cancers and cardiovascular and respiratory diseases. An article in the current issue (Am J Epidemiol. 2013;177(3):202–212) reports that classic dermatological manifestations, typically associated with chronic arsenic exposure, are predictive of internal cancers among Taiwanese decades after the cessation of exposure. Specifically, the risk of lung and urothelial cancers was elevated, which was evident regardless of arsenic dose, smoking, and age. There was also an unexpected elevated risk of prostate cancer.

Abstract Recent findings in familial hidradenitis suppurativa (HS) demonstrated loss‐of‐function mutations of components of the γ‐secretase (GS) complex leading to decreased protease cleaving activity, which may compromise canonical Notch signalling. Appropriate Notch signalling is of pivotal importance for maintaining the inner and outer root sheath of the hair follicle and skin appendages. This viewpoint on the pathogenesis of HS is primarily supported by circumstantial evidence derived from translational biology. Impaired Notch signalling is proposed to be the major pathogenic mechanism of HS. Deficient Notch sig...

“9‐cis Retinoic Acid is the ALDH1A1 Product that Stimulates Melanogenesis”
In this study, a combination of RNAi and pharmacologic approaches were used to determine which ALDH1A1 substrates and products regulate melanogenesis. Initial studies revealed that neither the UV‐induced lipid aldehyde 4‐hydroxy‐2‐nonenal nor the ALDH1A1 product all‐trans retinoic acid appreciably induced melanogenesis. In contrast, both the ALDH1A1 substrate 9‐cis retinal and its corresponding product 9‐cis retinoic acid potently induced the accumulation of MITF mRNA, Tyrosinase mRNA, and melanin. ALDH1A1 depletion inhibited the ability of 9‐cis retinal but not 9‐cis retinoic acid to stimulate melanogene...
