| Traumatic memories that haunt people with post-traumatic stress disorder might be eased by a pill from Novartis now used to treat multiple sclerosis, a study of mice suggests.
Mice given Novartis' Gilenya were faster at getting rid of acquired-fear memories, according to a study published Sunday in the journal Nature Neuroscience. The thought-erasing action of the medicine was linked to a newly discovered mechanism unrelated to its immune-suppressing properties that treat MS, researchers said.
Gilenya, also known as fingolimod, is the first oral drug approved for MS, though its beneficial effects in the central nervous system aren't well understood, the researchers said. The study found that the therapy from Basel, Switzerland-based Novartis also inhibits an enzyme called histone deacetylase, and consequently enhances gene-expression processes associated with memory and learning.
"We saw an effect in mice to forget adverse memory," said Sarah Spiegel, the lead study author and chairwoman of the department of biochemistry and molecular biology at the Virginia Commonwealth University School of Medicine.
