Researchers have made a discovery that could bring relief to those struggling with long COVID. In a world-first finding, they've identified a way to restore the faulty function of ion channels on immune cells using a well-known drug. The breakthrough, builds on previous research showing long COVID patients share similar issues with ion channels as those with chronic fatigue syndrome (also known as myalgic encephalomyelitis or ME/CFS). The team had previously shown success in restoring ion channel function in ME/CFS patients using a drug called Naltrexone, and now they've achieved similar results with long COVID patients. "Ion channels are integral...
