The skin and brain have a close bi-directional anatomical and functional connection. Historically, the skin-brain axis and the brain-skin axis have been well described. However, brain function in this context has only recently been demystified with the introduction of functional neuroimaging in dermatology. Functional neuroimaging, especially functional magnetic resonance imaging (fMRI), allows indirect visualisation of brain function. This review looks back to the beginnings of functional neuroimaging in dermatology, summarises the currently available dermatology-related fMRI-studies and discusses the potential future role of fMRI as a stratifying tool in clinical dermatology and in the development of novel therapies...

TNFα-, IL-23- and IL-17-targeting drugs are highly effective in the treatment of psoriasis. However, the precise molecular mechanism remains unknown. In psoriatic skin the presence of Langerhans cells (LC) is reduced, but the role of LC is poorly understood. The purpose of this study was to investigate the impact of TNFα and IL-23/IL-17 on the presence of LC in the skin during treatment. Therefore, psoriatic skin was investigated before and after 4 days of adalimumab or ustekinumab treatment. Furthermore, TNFα and IL-17A stimulation was investigated in an ex vivo model of epidermis and dermis from healthy normal skin kept in cultures at an air-liquid interphase for 4 days...

The advent of targeted therapies of metastatic melanoma, such as MAPK pathway inhibitors and immune checkpoint antagonists, has turned dermato-oncology from the 'bad guy' to the 'poster child' in oncology. Current targeted therapies are effective; although here is a clear need to develop combination therapies to delay the onset of resistance. Many anti-melanoma drugs impact on the cell cycle but are also dependent on certain cell cycle phases resulting in cell cycle phase-specific drug insensitivity. Here, we raise the question: Have combination trials been abandoned prematurely as ineffective possibly only because drug scheduling was not optimized? Firstly, if both drugs of a combination hit targets in the same melanoma cell, cell cycle-mediated drug insensitivity should be taken into account when planning combination therapies, timing of dosing schedules and choice of drug therapies in solid tumors...

Darier disease (DD) is a genetic skin disease that is associated with mutations in the ATP2A2 gene encoding the type 2 sarco/endoplasmic reticulum Ca(2+) -ATPase (SERCA2). Mutations of this gene result in alterations of calcium homeostasis, abnormal epidermal adhesion and dyskeratosis. Silencing of ATP2A2 in monolayer cell culture of keratinocytes reduces desmoplakin expression at the borders of cells and impacts cell adhesion. Here, we report establishment of a three-dimensional (3D) epidermal model of DD, and use this model to evaluate peptide therapy with tuberoinfundibular peptide of 39 residues (TIP39) to normalize calcium transport...

REVIEW

Mast cells (MC) are hemopoietically-derived tissue immune cells that are ubiquitous in the body, including neuroendocrine organs such as the hypothalamus, pineal, pituitary, ovaries, pancreas and uterus where their action is not well understood. Mast cells have historically been associated with allergies because of their rich content of histamine and tryptase, but more recently with regulation of immunity and inflammation due their synthesis and release of numerous cytokines and chemokines. Mast cells are located perivascularly and express numerous receptors for diverse ligands such as allergens, pathogens, neurotransmitters, neuropeptides and hormones including acetylcholine, calcitonin gene-related peptide (CGRP), corticosteroids, corticotropin-releasing hormone (CRH), β-endorphin, epinephrine, 17β-estradiol, gonadotrophins, hemokinin-A (HKA), leptin, melatonin, neurotensin (NT), parathyroid hormone (PTH), substance P (SP) and vasoactive instestinal peptide (VIP)...

: Propionibacterium acnes (P. acnes), the sebaceous gland and follicular keratinocytes are considered the three actors involved in the development of acne. This exploratory study investigated the characteristics of the skin microbiota in subjects with acne and determined microbiota changes after 28 days of application of erythromycin 4% or a dermocosmetic. Skin Microbiota were collected under axenic conditions from comedones, papulo-pustular lesions and nonlesional skin areas from subjects with mild to moderate acne according to the GEA Grading using swabs...

Loss-of-function melanocortin 1 receptor (MC1R) polymorphisms are common in UV-sensitive fair-skinned individuals and are associated with blunted cAMP second messenger signaling and higher lifetime risk of melanoma because of diminished ability of melanocytes to cope with UV damage. cAMP signaling positions melanocytes to resist UV injury by up-regulating synthesis of UV-blocking eumelanin pigment and by enhancing the repair of UV-induced DNA damage. cAMP enhances melanocyte nucleotide excision repair (NER), the genome maintenance pathway responsible for the removal of mutagenic UV photolesions, through cAMP-activated protein kinase (protein kinase A)-mediated phosphorylation of the ataxia telangiectasia mutated and Rad3 related (ATR) protein on the S435 residue...

Insulin like growth factor 1 (IGF1) is important for skin development and homeostasis. However, overexpression and inactivation studies have produced variable findings regarding its role in hair follicle (HF) biology. Here, we studied a conditional and inducible knockout of the IGF1 receptor (IGF1R) in keratin 15-expressing bulge cells. Deletion of IGF1R after the development of the skin appendages in K15-IGF1R(KO) mice showed no abnormalities in epidermal homeostasis. Numbers of bulge cells were lower in K15-IGF1R(KO) mice than in controls, without consequences on wound healing, at least in young mice...

Mice with mutations in SHANK-associated RH domain interactor (Sharpin) develop a hypereosinophilic auto-inflammatory disease known as chronic proliferative dermatitis. Affected mice have increased apoptosis in the keratinocytes of the skin, esophagus, and forestomach driven by extrinsic TNF receptor mediated apoptotic signaling pathways. FAS receptor signaling is an extrinsic apoptotic signaling mechanism frequently involved in inflammatory skin diseases. Compound mutations in Sharpin and Fas or Fasl were created to determine if these death domain proteins influenced the cutaneous phenotype in Sharpin null mice...

Chronic dermal wounds are a devastating problem that disproportionally affect individuals with conditions such as diabetes, paralysis, or simply old age. These wounds are extremely challenging to treat due to a heterogeneous combination of causative factors, creating a substantial burden on healthcare systems worldwide. Despite their large impact, there is currently a startling lack of options for effectively treating the underlying biological changes that occur within the wounds. Biomaterials possess an enticing ability to provide new comprehensive approaches to healing these devastating wounds; advanced wound dressings are now being developed that enable the ability to coordinate temporal delivery of multiple therapeutics, protect sensitive biologics from degradation, and provide supportive matrices that encourage the growth of tissue...

Vitiligo is an acquired condition characterized by depigmented, cutaneous lesions that result from the death of pigment-producing cells, melanocytes. The occurrence of oxidative stress has been proposed as a pathogenetic mechanism for melanocyte degeneration in vitiligo. Therefore, in this study, we investigated the cytoprotective effects of afzelin against oxidative stress and its mechanism of action in human epidermal melanocytes. We found that afzelin significantly inhibited hydrogen peroxide-induced cell death, cellular reactive oxygen species production, and lipid peroxidation in melanocytes...

Psoriasis skin lesions are characterized by dramatic changes in the transcriptome, reflecting altered activity of multiple signaling pathways in resident and infiltrating cells. MiRNAs are small non-coding RNAs that have a large impact on cellular functions by regulating multiple genes simultaneously, and they have been shown to play key roles in skin homeostasis and inflammation. In this commentary to the review article "MicroRNAs in Psoriasis: Immunological Functions and Potential Biomarkers" by Liu et al...
