Melanin, melanin "ghosts," and melanin composition in Cryptococcus neoformans [PDF]
Infection and Immunity, 1996 Melanin synthesis is associated with virulence for the pathogenic fungus Cryptococcus neoformans. Exposure of nonmelanized C. neoformans 4067 cells to 4 M guanidinium isothiocyanate followed by 6 M HCl at 100 degrees C resulted in complete solubilization of cellular structures. However, exposure of melanized C.

Melanin and Melanin-Like Hybrid Materials in Regenerative Medicine [PDF]
Nanomaterials, 2020 Melanins are a group of dark insoluble pigments found widespread in nature. In mammals, the brown-black eumelanins and the reddish-yellow pheomelanins are the main determinants of skin, hair, and eye pigmentation and play a significant role in photoprotection as well as in many biological functions ensuring homeostasis.
