29-year-old Lynndrick Holmes of Mobile, Alabama has been declared sickle-cell free after undergoing a two-year clinical trial to treat his disease. If he remains stable for five years, he will be declared cured. The experimental gene therapy involves modifying stem cells from Holmes’ own bone marrow to alter the gene that causes sickle cell disease.

Three studies recently published in Nature describe how the nervous system comes into play during cancer growth. Researchers found some cancer cells that behave like neurons, which can help the tumor infiltrate the brain. They found this system in brain tumors, or gliomas, as well as in some breast cancers. While the results were surprising for the researchers, they may also open new treatment opportunities for oncologists.
