"Persistent Inflammatory Protein Levels in Long COVID: A Potential Treatment Target"

A University of Cambridge-led study has identified the protein interferon gamma (IFN-γ) as a potential biomarker for Long COVID fatigue, shedding light on an immunological mechanism underlying the disease and paving the way for potential therapies. The study followed Long COVID patients for over 2.5 years and found persistently high levels of IFN-γ, suggesting a potential mechanism for the condition. The research also suggests that vaccination may help clear IFN-γ in Long COVID patients, and argues for classifying Long COVID into subtypes to personalize treatment.
