Are Misbehaving Antibodies the Culprit Behind Long COVID?

Researchers found that antibodies from people with long COVID can cause increased pain sensitivity and reduced movement in mice. This suggests that these antibodies might contribute to long COVID symptoms by attacking healthy tissues. Although the study involved a small number of participants and needs further validation, it provides a potential new way to study long COVID and could influence future treatments and policies, such as excluding long COVID patients from blood donations.

Key Insights

• Insight 1: Researchers found that antibodies from people with long COVID can cause increased pain sensitivity and reduced movement in mice. This suggests that these antibodies might be responsible for some long COVID symptoms.
• Insight 2: The study showed that different groups of antibodies had distinct effects on the mice, indicating that long COVID symptoms could vary based on the specific antibodies present.
• Insight 3: If these findings are confirmed, it could lead to new ways to study long COVID and potentially influence guidelines on blood donations from people with long COVID. However, more research is needed to fully understand the implications.
