Differential Antifungal Activity of Human and Cryptococcal Melanins with Structural Discrepancies [PDF]

Frontiers in Microbiology, 2017
Melanin is a pigment found in all biological kingdoms, and plays a key role in protection against ultraviolet radiation, oxidizing agents, and ionizing radiation damage. Melanin exerts an antimicrobial activity against bacteria, fungi, and parasites.

Shedding light on melanins within in situ human eye melanocytes using 2-photon microscopy profiling techniques. [PDF]

Scientific Reports, 2019
Choroidal melanocytes (HCMs) are melanin-producing cells in the vascular uvea of the human eye (iris, ciliary body and choroid). These cranial neural crest-derived cells migrate to populate a mesodermal microenvironment, and display cellular functions ...
