At ORIEMS FIT RESEARCH DIGEST, we explore exciting new scientific discoveries that spark curiosity and encourage learning. Today, we’re looking at a fascinating study about fibromyalgia, a condition that causes chronic pain, fatigue, and sensitivity.
Scientists have found that fibromyalgia symptoms might be caused by antibodies in the blood—and these symptoms can even be transferred from humans to mice!

Who Did This Research and When?
This study was conducted by researchers from:
- Karolinska Institute (Sweden) – One of the world’s leading medical universities.
- King’s College London (UK) – A highly respected research university.
- University of Liverpool (UK) – Home to top experts in pain research.
It was published in 2021 in the Journal of Clinical Investigation, a well-known scientific journal.
Who Funded This Research?
One of the researchers received funding from Eli Lilly & Co., a pharmaceutical company.
What Is This Research About?
Scientists wanted to find out if fibromyalgia symptoms are caused by something in the blood—specifically, antibodies (a part of the immune system). To test this, they took antibodies from people with fibromyalgia and injected them into mice to see if the mice developed symptoms.
Who Was This Study Done On?
- People with fibromyalgia (who experience chronic pain).
- Healthy people (for comparison).
- Mice, which were injected with antibodies from both groups.
What Did the Researchers Do?
- They took blood samples from people with fibromyalgia and from healthy individuals.
- They separated out the antibodies from the blood.
- They injected the antibodies into mice for 4 days.
- They observed the mice to see if they developed fibromyalgia-like symptoms.
What Did They Find?
- Mice injected with fibromyalgia antibodies became more sensitive to pain—they reacted more strongly to pressure and cold temperatures.
- These mice also showed reduced grip strength (a sign of muscle weakness).
- The antibodies attached themselves to nerve cells and glial cells in the mice, affecting how they processed pain.
- In contrast, mice injected with antibodies from healthy people did not develop any pain symptoms.
What Do These Findings Mean?
This study suggests that fibromyalgia is an immune-related condition. Instead of being just a problem with the brain or nerves, the immune system may be playing a big role in causing pain.
Specific Evidence Supporting These Findings
- 100% of the fibromyalgia antibody-injected mice developed pain sensitivity.
- 7 out of 8 mice also became sensitive to cold temperatures.
- Mice injected with antibodies from healthy people showed no symptoms.
- The symptoms lasted for about 2-3 weeks before disappearing, matching the time it takes for human antibodies to break down in mice.
Why This Study Is Important
Understanding that fibromyalgia may be linked to the immune system could help scientists develop better treatments. If antibodies are the cause, therapies that remove or block these antibodies might reduce symptoms.
How Might This Study Help People with Fibromyalgia?
If fibromyalgia is caused by immune system antibodies, future treatments could include:
- Antibody-reducing therapies (such as plasma exchange).
- New drugs that block the effects of these antibodies.
- More personalized treatments for people with chronic pain.
