Vitiligo is a chronic skin disease characterized by the appearance of zones of depigmentation. It is mostly described as an autoimmune disease in which the immune system destroys the melanocytes. Consistent with this origin, genetic studies have implicated genes encoding proteins mediating the immune response targeting melanocytes in the etiology of this disease, together with proteins specific to these cells.

Background: Early accurate detection of all skin cancer types is important to guide appropriate management, to reduce morbidity and to improve survival. Basal cell carcinoma (BCC) is almost always a localised skin cancer with potential to infiltrate and damage surrounding tissue, whereas a minority of cutaneous squamous cell carcinomas (cSCCs) and invasive melanomas are higher-risk skin cancers with the potential to metastasise and cause death. Dermoscopy has become an important tool to assist specialist clinicians in the diagnosis of melanoma, and is increasingly used in primary-care settings. Read More

Background: The World-famous UNESCO heritage from the Paleolithic human society, Lascaux Cave (France), has endeavored intense microclimatic perturbations, in part due to high touristic pressure. These perturbations have resulted in numerous disturbances of the cave ecosystem, including on its microbial compartment, which resulted in the formation of black stains especially on the rock faces of the passage. We investigated the cave microbiome in this part of Lascaux by sampling three mineral substrates (soil, banks, and inclined planes) on and outside stains to assess current cave microbial assemblage and explore the possibility that pigmented microorganisms involved in stain development occur as microbial consortia.

The ascidian larva has a pigmented ocellus comprised of a cup-shaped array of approximately 30 photoreceptor cells, a pigment cell, and three lens cells. Morphological, physiological and molecular evidence has suggested evolutionary kinship between the ascidian larval photoreceptors and vertebrate retinal and/or pineal photoreceptors. Rx, an essential factor for vertebrate photoreceptor development, has also been suggested to be involved in the development of the ascidian photoreceptor cells, but a recent revision of the photoreceptor cell lineage raised a crucial discrepancy between the reported expression patterns of Rx and the cell lineage.

Retinal pigment epithelial cells (RPEs), a pigmented cell layer in the outer retina, are constantly exposed to photo-oxidative stress. Autophagy relieves the stress by removing oxidative protein adducts, protein aggregates, and damaged mitochondria. We previously found that miR-29 is downregulated in choroid/RPE tissue in a model of exudative age-related macular degeneration (AMD), suggesting that miR-29 deficiency may contribute to autophagy inhibition and AMD progression.

Dendritic cells (DCs) are key targets for immunity and tolerance induction; they present donor antigens to recipient T cells by donor- and recipient-derived pathways. Donor-derived DCs, which are critical during the acute posttransplantation period, can be depleted in graft tissue by forced migration via UVB irradiation. Here, we investigated the tolerogenic potential of donor-derived DC depletion through in vivo and ex vivo UVB preirradiation (UV) combined with injection of anti-CD154 Ab into recipients in an MHC-mismatched hair follicle (HF) allograft model in humanized mice.

Pigmented breast cancer in the skin caused by nonneoplastic melanocytes of epidermal origin is a rare condition of metastasis from breast cancer, but the pathogenesis of this phenomenon is almost unknown. In this report, we describe a case of breast cancer metastasis in the skin with prominent hyperkeratotic pigmentation caused by nonneoplastic melanocyte colonization. Immunohistochemical staining revealed that the metastatic tumor cells produced IL-23, which is reported not only to induce IL-17 but also to inhibit cell apoptosis in breast cancer cells, which affects tumor progression.
