UVA induces 40 times more DNA single strand breaks in human melanocytes from dark skin than in melanocytes from light skin (134). Given that UVA damage is largely thought to occur via …

Our findings demonstrate that the equivalent of seconds to minutes of sun exposure depolarizes melanocytes and that melanocyte depolarization contributes to the elevated intracellular Ca 2+ …

In light of substantial discoveries in epithelial and hair pigmentation pathophysiology, this review summarizes the current understanding of skin pigmentation mechanisms. Melanocytes are …

Yellow and red light impose possible stimulation on the onset and aggravation of vitiligo by affecting the viability and survival of melanocytes and the progression of melanin production.

Melanocytes reside within the basal epidermis of human skin, and function to protect the skin from ultraviolet light through the production of melanin. Prolonged exposure of the skin to UV light …

Melanin synthesized in the melanocytes plays an important role in protecting the skin from radiation-induced damage. Melanocytes transfer melanosomes to keratinocytes, where …

Here, we show that visible light can damage melanocytes through melanin photosensitization and singlet oxygen (1 O 2) generation, thus decreasing cell viability, increasing membrane …

In conclusion, our results demonstrate that human melanocytes use a novel mechanism to sense and respond to ultraviolet light, in which UVA activates endogenous opsin receptors to cause …

The purpose of this study was to determine the effect of visible light on the pro-pigmentation pathways and melanin formation in skin. Exposure to visible light in ex-vivo and clinical studies …

In this review, we discuss the protective role of melanocytes against UV-induced DNA damage and how genetic variations, including those in p53 and melanocortin-1 receptor (MC1R), or …

UV damage at transcription factor binding sites and melanoma mutations. a A region 100–150 base pairs upstream of the transcription start site of the PCNA gene acquires high levels of …

The melanopsin system responsible for photoentrainment, was isolated from the photosensitive dermal melanophores of frogs Xenopus laevis responding to light. Melanocytes form a …

Alpha-melanocyte-stimulating hormone (alpha-MSH) increases melanogenesis and protects from UV-induced DNA damage. However, its effect on mitochondrial DNA (mtDNA) damage is …

The link between solar radiation and melanoma is still elusive. Although infrared radiation (IR) accounts for over 50% of terrestrial solar energy, its influence on human skin is not well …

In this report, we examine the effect of a combination of UV treatment and metal ion exposure on melanosomes within melanocytes, as well as their ability to act as pro-oxidants in ex situ …

The present work aimed at evaluating the dependence of UV-induced DNA damage on melanin content and distribution, using reconstructed human epidermis (RHE) models. Tanned and …

We propose that one subpopulation of melanocytes, i.e. “detector” melanocytes, would respond to environmental stimuli such as UVB with production and release of CRH, that would induce …

The presented results indicated that minocycline and UV radiation could directly influence melanocyte physiology and stimulated melanin synthesis. It was shown that both tested …

Melanocytes produce two chemically distinct types of melanin: the brown-black eumelanin, and the yellow-red pheomelanin [10, 11, 12, 13, 14]. The type of melanin produced depends on the …
