Factor H

Factor H is a protein in your blood that helps regulate the immune system, specifically the complement system, which fights infections. Its main role is to prevent the immune system from attacking your own body’s healthy cells by controlling and stopping excessive activation of complement proteins. This regulation ensures that the immune response is targeted only at harmful invaders like bacteria, reducing the risk of tissue damage or autoimmune conditions. Proper functioning of Factor H is essential for maintaining immune balance and protecting your tissues during immune responses.
