MelLec recognizes melanin in conidial spores of Aspergillus fumigatus as well as in other DHN-melanized fungi. MelLec is ubiquitously expressed by CD31+endothelial cells in mice, and is also expressed by a sub-
What is melanin and why is it important? Pigments: A pigment may be defined as a molecule or material that is able to change the color of reflected or transmitted light due to its selective absorption of light wavelengths. In biology, pigment is found in the fur, skin, hair, and eye co...
His darker pigmentation is the result of the presence of high levels of melanin, a molecule that protects his skin against the ultraviolet rays of the sun. Without melanin acting as a shield from the sun, the Ibo man would burn or contract skin cancer. [ILLUSTRATION OMITTED] The ...
Pigmentation is caused by the distribution of melanin, a black or brown pigment molecule, under your skin. This pigment exists to protect your skin cells from the sun, and everybody has it. But normally, we don’t notice a nice, even distribution of melanin. We just like how it looks—...
The therapeutic options for Alzheimer’s disease (AD) are limited, underscoring the critical need for finding an effective regulator of Aβ42 production. In this study, with 489 human postmortem brains, we revealed that homotrimer G protein subunit gamma 5 (GNG5) expression is upregulated in ...
It links ageing to a potentially detrimental characteristic of these neurons, and since neuromelanin (see below) is believed to bind iron and chelate it, again gives a plausible link between two important features of these neurons. The affinity of iron for melanin is much lower than for iron ...

(a) DCs and T cells emigrating from skin explants were identified by FACS. CD14 and CD1c labeling was determined on the gated DC-containing population. (b) HLA-DR, MR, and Dendritic Cell–Specific Intercellular adhesion molecule-3–Grabbing Nonintegrin (DC-SIGN) expression was measured on gat...
A retrospective study showed that melanin levels are lower in women with ovarian cancer compared with healthy ones (41.8 versus 82.4 pg/mL) [28]. Even though there is no significant relationship between urinary melatonin levels and ovarian cancer risk in women, several evidence shows that ...
Resveratrol (trans-3,5,4′-trihydroxystilbene) is a polyphenolic compound present in grapes and blueberries and has strong anti-oxidative activities [3, 4]. This compound also exhibits an inhibitory effect on melanin synthesis, anti-inflammatory activity, anti-cancer, and osteoblast differentiation [...
