Active Transposable Elements in Immune Cells Can Lead to Flu-Like Symptoms in Fibromyalgia, Study Finds
Active transposable elements — small DNA fragments that can change position within the genome — found in immune cells of women with fibromyalgia can increase the levels of certain immune proteins, and be the reason why some patients experience flu-like symptoms, a study suggests. The study, “Activation of Transposable Elements in Immune Cells of Fibromyalgia Patients,” was published in the International Journal of Molecular Sciences. People with fibromyalgia frequently have myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), a condition characterized by overwhelming fatigue that is not alleviated by rest.  While both fibromyalgia and ME/CFS share common features, including abnormal immune function and infectious flu-like symptoms, no clear connection with viral infections has been found.  In 2019, a team of investigators at the
