Melanization of Candida auris Is Associated with Alteration of Extracellular pH
Journal of Fungi, 2022 Candida auris is a recently emerged global fungal pathogen, which causes life-threatening infections, often in healthcare settings. C. auris infections are worrisome because the fungus is often resistant to multiple antifungal drug classes.

Melanin Promotes Spore Production in the Rice Blast Fungus Magnaporthe oryzae
Frontiers in Microbiology, 2022 The rice blast pathogen, Magnaporthe oryzae, spreads through spores and invades rice through appressoria. Melanin is necessary for an appressorium to penetrate plant cells, but there are many unknown aspects of its role in fungal conidiation.

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.

Pathogenic Roles for Fungal Melanins [PDF]
Clinical Microbiology Reviews, 2000 SUMMARY Melanins represent virulence factors for several pathogenic fungi; the number of examples is growing. Thus, albino mutants of several genera (in one case, mutated precisely in the melanizing enzyme) exhibit decreased virulence in mice.

Differential Antifungal Activity of Human and Cryptococcal Melanins with Structural Discrepancies
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.

The role of L-DOPA on melanization and mycelial production in Malassezia furfur. [PDF]
PLoS ONE, 2013 Melanins are synthesized by organisms of all biological kingdoms and comprise a heterogeneous class of natural pigments. Certain of these polymers have been implicated in the pathogenesis of several important human fungal pathogens.

Fungal Melanin Rewires Macrophage Metabolism
Trends in Biochemical Sciences, 2020 Aspergillus fumigatus is a deadly fungal pathogen in immunocompromised patients. A report by Gonçalves et al. reveals that melanin, a secondary metabolite present at the surface of infecting fungal spores, induces glycolysis in macrophages to promote inflammatory responses.
