FDA-approved drug restores hair in patients with Alopecia Areata

New York: Researchers at Columbia University Medical Centre (CUMC) have identified the immune cells responsible for destroying hair follicles in people with alopecia areata, a common autoimmune disease that causes hair loss, and have tested an FDA-approved drug that eliminated these immune cells and restored hair growth in a small number of patients. The results appear in Nature Medicine. more

Human ‘hairless’ gene identified: One form of baldness explained

Washington: A new research report appearing in The FASEB (Federation of American Societies for Experimental Biology) Journal explains why people with a rare balding condition called “atrichia with papular lesions” lose their hair, and it identifies a strategy for reversing this hair loss. more

Hair regeneration method uses patient’s own cells to grow new hair

Hair regeneration method uses patient’s own cells to grow new hair

New York: Researchers at Columbia University Medical Centre (CUMC) have devised a hair restoration method that can generate new human hair growth, rather than simply redistribute hair from one part of the scalp to another. The approach could significantly expand the use of hair transplantation to women with hair loss, who tend to have insufficient donor hair, as well as to men in early stages of baldness. The study is published in the Proceedings of the National Academy of Sciences (PNAS). more

Hormone plays surprise role in fighting skin infections

Hormone plays surprise role in fighting skin infections

Washington: Antimicrobial peptides (AMPs) are molecules produced in the skin to fend off infection-causing microbes. Vitamin D has been credited with a role in their production and in the body’s overall immune response, but scientists at the University of California, San Diego School of Medicine say a hormone previously associated only with maintaining calcium homeostasis and bone health is also critical, boosting AMP expression when dietary vitamin D levels are inadequate. more
