"Blood Signals of Long COVID Uncover Potential Treatments"
A study published in Science analyzed blood samples from long-COVID patients and found significant serum protein changes, indicating a dysregulation of the complement system, which could be behind the varied symptoms experienced by these patients. The findings suggest potential for developing biomarker-based tests to identify the condition and may lead to targeted therapies for long-COVID patients. However, experts caution that larger studies are needed to replicate the findings and that it's premature to apply new treatments based on these results.
