Study Uncovers Early Rejection Markers in Pig Kidney Transplants
Scientists are working on a way to use pig kidneys to help people who need new ones.
They've found that human bodies sometimes try to reject these pig kidneys.
This study looked at how the body's defenses, the immune system, react to the pig kidney.
They used special tools to see the immune cells in action.
They noticed that rejection starts quickly after the transplant.
They found some key cells that cause rejection.
When they used medicine to stop the rejection, it worked.
This helps scientists learn how to make the pig kidneys work well in people.
The next step is to improve treatments and look for early signs of rejection.
Study explores how human immune cells interact with pig kidney tissue in transplants.
Researchers used spatial molecular imaging to identify early rejection markers.
Antibody-mediated rejection signs were observed as early as Day 10, peaking at Day 33.
Macrophages and myeloid cells were found to be the most prevalent immune cell types.
Targeted therapeutic interventions successfully weakened immune-mediated rejection signs.
