Hydroxylation of dehydroepiandrosterone in human scalp hair follicles

The British Journal of Dermatology
A J VermorkenH Bloemendal


The dehydroepiandrosterone hydroxylating enzyme system in the hair follicle has been characterized. It is found in the particulate fraction of the follicle, and is inhibited by carbon monoxide and the cytochrome P450 inhibitor metyrapone, and appears to be dependent upon NADPH. In these major characteristics the hair follicle enzyme is very similar to the liver monooxygenase system.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration
