Guided by gut sensory cues, humans and animals prefer nutritive sugars over non-caloric sweeteners, but how the gut steers such preferences remains unknown. In the intestine, neuropod cells synapse with vagal neurons to convey sugar stimuli to the brain
P. Mechanism of immune suppression by ultraviolet irradiation in vivo. I. Evidence for the existence of a unique photoreceptor in skin and its role in photoimmunology. J. Exp. Med. 158, 84–98 (1983). The first demonstration that UV-irradiated mice are unable to reject UVR-induced tumours,...
Describe the role of melanocytes in skin pigmentation Although you may not typically think of the skin as an organ, it is in fact made of tissues that work together as a single structure to perform unique and critical functions. The skin and its accessory structures make up theintegumentary sy...

Acne, melasma, and alopecia are among the most common skin disorders seen in this patient population. Understanding the differences in the basic science of skin and hair is imperative in addressing their unique needs. Despite the paucity of conclusive data on racial and ethnic differences in skin...
Skin photoaging largely depends on the presence of melanin in the cells, which acts as the first level of defense against UV radiation. However, excess production of melanin can lead to damage like melasma, freckles, and senile lentigo. During exposure to UV radiation, tyrosinase is activated,...
Black beauty consumers and brands face deep challenges when it comes to equity. Removing those barriers can lead to greater opportunity for everyone in the industry. Hair, makeup, and skin care:for billions of people worldwide, beauty products are a fundamental part of how others view them ...
The endothelium is a monolayer of cells on the posterior corneal surface that transports water from the stroma into the anterior chamber. This movement of water counters a natural tendency for the stroma to swell and is necessary to maintain a transparen
