Diversified Stimuli-Induced Inflammatory Pathways Cause Skin Pigmentation
International Journal of Molecular Sciences, 2021 The production of melanin pigments by melanocytes and their quantity, quality, and distribution play a decisive role in determining human skin, eye, and hair color, and protect the skin from adverse effects of ultraviolet radiation (UVR) and oxidative ...

Alterations of the pigmentation system in the aging process
Pigment Cell & Melanoma Research, 2021 Human skin aging is a natural phenomenon that results from continuous exposure to intrinsic (time, genetic factors, hormones) as well as extrinsic factors (UV exposure, pollution, tobacco).

Melanosome biogenesis in the pigmentation of mammalian skin.
Integrative and Comparative Biology, 2021 Melanins, the main pigments of the skin and hair in mammals, are synthesized within membrane-bound organelles of melanocytes called melanosomes. Melanosome structure and function are determined by a cohort of resident transmembrane proteins, many of ...

Skin pigmentation and its control: From ultraviolet radiation to stem cells
Experimental Dermatology, 2020 In the light of substantial discoveries in epithelial and hair pigmentation pathophysiology, this review summarizes the current understanding of skin pigmentation mechanisms. Melanocytes are pigment‐producing cells, and their key regulating transcription
