Correlation between urinary melanin-related metabolites and tumour weight in melanoma-bearing mice
Ito S, Wakamatsu K, Inoue S, Fujita K.
Melanoma tissues produce not only 5-S-cysteinyldopa (5-S-CD), a pheomelanin precursor, but also 5,6-dihydroxyindoles, eumelanin precursors. We compared 5-S-CD and eumelanin-related metabolites regarding the correlation of their production in melanoma and excretion in urine, versus the weight of B16 mouse melanoma. It was found that B16 melanoma tissues produce 5,6-dihydroxyindole-2-carboxylic acid ...

Circular and branched Birbeck granules and cytomembrane blebbing in Langerhans´ cells after dithranol irritation
Kanerva L.
Mild dithranol irritation of healthy human skin has a stronger effect on the fine structure of Langerhans´ cells (LC) than on that of other epidermal cells, causing mitochondrial enlargement and disruption of the cristae of LCs. With a stronger dithranol irritation, LCs were even more affected resulting in circular and branched Birbeck granules (BG) and blebbing of the LC cytomembrane. More often ...

Human epidermal Langerhans´ cells are sensitive to rapid cooling by ethyl chloride
Warfvinge K, Andersson L, Bartosik J.
Topical anesthesia with ethyl chloride spraying generates some remarkable reactive events in the human Langerhans´ cell (LC) system. Many LC retract their dendrites and a considerable number move to the innermost layers of the epidermis within 15 minutes. This rapid motility supports the view that the interstices between cells in living epidermis are large. The LC cytomembrane is very susceptible ...
