Melanin particles isolated from the fungus Fonsecaea pedrosoi activates the human complement system

Memorias do Instituto Oswaldo Cruz, 2018
BACKGROUND Melanin production has been associated with virulence in various pathogenic fungi, including Fonsecaea pedrosoi, the major etiological agent for chromoblastomycosis, a subcutaneous fungal disease that occurs in South America.

Solubilized melanin suppresses macrophage function

FEBS Open Bio, 2019
Melanin‐producing Cryptococcus and Aspergillus are highly invasive and can suppress or escape the immune system of the host. Since non‐melanin‐producing strains do not affect the immune system, melanin may play a role in immune system suppression ...

Synthesis and study of polyhydroxylated phenol derivatives with potential cosmetic and phytoiatric applications [PDF]

, 2013
Tyrosinase (polyphenol oxidase, E.C. 1.14.18.1) and laccase (phenol oxidase, E.C. 1.10.3.2) are multifunctional copper-containing enzymes, that are keys in melanin biosynthesis, melanisation in animals and browning in plants.

Vital dye labelling of Xenopus laevis trunk neural crest reveals multipotency and novel pathways of migration [PDF]

, 1993
Although the Xenopus embryo has served as an important model system for both molecular and cellular studies of vertebrate development, comparatively little is known about its neural crest.

Research progress on peptides that inhibit melanin synthesis

Frontiers in Pharmacology
Melanin produced by melanocytes, primarily determines human skin color and protects against ultraviolet radiation. However, excessive melanin deposition can lead to skin conditions such as freckles, age spots, and moles, potentially causing aesthetic ...

Data on melanin production in B16F1 melanoma cells in the presence of emu oil

Data in Brief, 2016
Here, we present data on the effects of emu oil, obtained from emu (Dromaius novaehollandiae) fat deposits, on melanogenesis in B16F1 murine melanoma cells.

High temporal-resolution transcriptome landscape reveals the biological process and regulatory genes of melanin deposition in breast muscle of Silkie chickens during embryonic development

BMC Genomics
Background Abnormal deposition of melanin in skeletal muscle is an interesting phenomenon and the Silkie is the most typical example. Melanin deposition involves multiple steps such as neural crest cell migration, melanocyte differentiation, melanosome ...
