What's floating in the heart's fluid?

Surprising Findings
iNKT cells are the only regulatory lymphocytes enriched in pericardial fluid.
Most regulatory immune cells were not more common in the heart’s fluid—only this rare, specialized type (iNKT) stood out, which is unexpected given the variety of immune regulators in the body.
Practical Takeaways
Understanding immune activity in pericardial fluid could help develop targeted anti-inflammatory treatments for heart disease.

People having heart bypass surgery show higher levels of certain immune cells in their heart fluid and blood compared to those having heart valve surgery — suggesting their bodies react differently depending on the type of heart disease they have.
After heart surgery, there's more of certain immune chemicals in the fluid around the heart than in the blood, which means the area around the heart may be more inflamed and actively calling in immune cells.
When people have heart surgery, the fluid around their heart has more of certain immune cells than their blood does — meaning the heart's surroundings might have a special kind of immune activity that helps watch for problems or control inflammation.
In people having heart surgery, a special type of immune cell called iNKT cells is found in much higher amounts in the fluid around the heart than in the blood — and it's the only immune cell type that shows up more in that heart fluid.
People having heart bypass surgery tend to have much higher levels of a protein linked to inflammation than people having heart valve surgery — this might mean their immune cells are more active because of their heart disease.
