BACKGROUND There is a need to develop an in vitro skin models which can be used as alternative system for research and testing pharmacological products in place of laboratory animals. Therefore to study the biology and pathophysiology of pigmentation and vitiligo, reliable in vitro skin pigmentation models are required. AIM In this study, we used primary cultured melanocytes and keratinocytes...

We have hypothesised that melanocytes disappear in vitiligo because they are weakly attached to the epidermal basal membrane (melanocytorrhagy). In the epidermis, attachment of melanocytes to collagen IV is mediated through DDR1, which is under the control of CCN3. DDR1 genetic variants have been associated with vitiligo in patients of different ethnic origin. In vitro studies have shown that i...

Generalized vitiligo is a common disorder in which patchy loss of skin and hair pigmentation principally appears to result from autoimmune loss of melanocytes from affected regions. We previously characterized a unique founder population in an isolated Romanian community with elevated prevalence of generalized vitiligo and other autoimmune diseases, including autoimmune thyroid disease, rheumat...

Hypersensitivity of epidermal melanocytes to oxidative stress is known to contribute to vitiligo pathogenesis. Molecular mechanisms that connect melanocyte redox homeostasis to the complex disease phenotype are not fully understood. Jian et al. show that vitiligo melanocytes have impaired nuclear factor erythroid 2-related factor 2 (Nrf2)-antioxidant response element signaling and decreased act...

Vitiligo is an autoimmune depigmentation disorder that is estimated to affect about .5% of the worldwide population. Half of all cases begin in childhood. A variety of advances occurred in the past two decades that have enhanced the management of childhood vitiligo. This contribution reviews recent advances in vitiligo, including a better understanding of the pathogenesis and autoimmune comorbi...

Vitamin D plays a role in the process of melanogenesis, namely increasing L-Dopa cells, inducing differentiation immature melanocytes, and melanocyte activity. The use vitamin dermatology is treatment vitiligo, psoriasis vulgaris, atopic dermatitis, verruca alopecia. Vitiligo an autoimmune disease skin form depigmentation due to destruction melanocytes by T cells. clinical manifestations vitili...

BACKGROUND In vitiligo, melanocytes are gradually lost in depigmented macules of the skin. The disappearance of melanocytes has, however, not been clearly observed and consequently the aetiology of the disease (autoimmune, neural, cytotoxic) is still elusive. The starting point of vitiligo macules is frequently determined by local conditions such as wounds and excoriations, but may also follow ...

Vitiligo is a common skin disease, affecting approximately 0.5% of the general population. It is characterized by milky white macules and patches, which are a psychological burden to many patients. Although this disease has been known for a long time, the etiology is still under debate. Since melanin is a unique light absorbing and ultraviolet filtering pigment, it is generally accepted that it...

Three cases of severe and irreversible alopecia occurring in patients with common variable immunodeficiency are described. In all three cases, hair loss developed after the diagnosis of immune deficiency; one of the patients also had extensive vitiligo. A fourth patient had vitiligo in the absence of alopecia. No change in the alopecia or vitiligo was noted in any patient as a result of immunog...
