UCLA researchers led by Dr. Donald Kohn have created a method for modifying blood stem cells to reverse the genetic mutation that causes a life-threatening autoimmune syndrome called IPEX. The gene therapy, which was tested in mice, is similar to the technique Kohn has used to cure patients with another immune disease, severe combined immune deficiency, or SCID, also known as bubble baby disease.
By stirring crosstalk among skin cells that form the roots of hair, researchers report they have regrown hair strands on damaged skin. The findings better explain why hair does not normally grow on wounded skin, and may help in the search for better drugs to restore hair growth, said the study's authors.
Researchers found five strains of a multidrug-resistant bacterium similar to hospital-acquired infections on the International Space Station (ISS), raising concerns about the organisms' health implications for future missions.
