Photopheresis

Photopheresis is a medical treatment that helps the body fight certain diseases by using a special type of light to activate the immune system. Your immune system is like a team of superheroes that protect your body from germs and bad guys. Sometimes, though, the immune system needs a little extra help.

During photopheresis, a special machine takes some of your blood out of your body and runs it through a process that uses special light to activate your immune cells. These activated immune cells are like the superheroes getting ready to fight the bad guys. Then, the blood is put back into your body and your activated immune cells can better attack and destroy the disease-causing cells.

This treatment is often used to help people with certain immune system disorders, such as graft-versus-host disease (GVHD), which can happen after a bone marrow transplant. It can also be used to treat certain types of skin disorders like cutaneous T-cell lymphoma.

Overall, photopheresis is a way to help your immune system fight back against harmful diseases and keep your body healthy.
