Antioxidant function of fungal melanin.

چکیده
Polyphenols have been implicated in the virulence and oxidant resistance of Cryptococcus neoformans. Although monomeric polyphenols did not protect against the prooxidant, plumbagin, polymeric dopamine-melanin conferred resistance both to hypochlorite and to permanganate. The physiologic antioxidant capacity conferred by melanin was found to be 21.3 x 10(-15) mole-equivalents per cell, a value which approximates oxidant production by stimulated macrophages.

Introduction: Saffron has some applications such as anti-spasmodic and analgesic effects in traditional medicine. The aim of this study was to evaluate the anti melanogenesis and antioxidant properties of crocin (one of the saffron active components) on B16F10 mouse melanoma cell line. Methods: In this experimental study, B16F10 cells were prepared from Pasteur Institute (NCBI) and were grow...
متن کاملIsolation and Characterization of Melanin Producing Pseudomonas stutzeri Strain UIS2 in the Presence of l-tyrosine and Survey of Biological Properties of Its Melanin
Background: Melanin is a negative charge hydrophobic complex pigment. Melanin is produced naturally in bacteria to protect them against UV, free radicals and environmental stresses. Pigment production in bacteria has more advantages than other biosources due to its rapid growth, higher efficiency and easier extraction. The aim of this study was the isolation, biochemical and molecular identific...
متن کاملThe Response of Dark Septate Endophytes (DSE) to Heavy Metals in Pure Culture
Dark septate endophytes (DSE) occur widely in association with plants exposed to heavy metal stress. However, little is known about the response of DSE exposed to heavy metals. In this study, five DSE were isolated from the roots of Astragalus adsurgens Pall. seedlings growing on lead-zinc mine tailings in China. Based on morphological characteristics and DNA sequence analyses, the isolates wer...
متن کاملCell Wall Modifications during Conidial Maturation of the Human Pathogenic Fungus Pseudallescheria boydii
Progress in extending the life expectancy of cystic fibrosis (CF) patients remains jeopardized by the increasing incidence of fungal respiratory infections. Pseudallescheria boydii (P. boydii), an emerging pathogen of humans, is a filamentous fungus frequently isolated from the respiratory secretions of CF patients. It is commonly believed that infection by this fungus occurs through inhalation...
متن کاملDetection of antibodies against Paracoccidioides brasiliensis melanin in in vitro and in vivo studies during infection.
Several cell wall constituents, including melanins or melanin-like compounds, have been implicated in the pathogenesis of a wide variety of microbial diseases caused by diverse species of pathogenic bacteria, fungi, and helminthes. Among these microorganisms, the dimorphic fungal pathogen Paracoccidioides brasiliensis produces melanin in its conidial and yeast forms. In the present study, melan...
