La CFI gene provides instructions for making a protein called complement factor I. This protein helps regulate a part of the body's immune response known as the complement system. The complement system is a group of proteins that work together to destroy foreign invaders (such as bacteria and viruses), trigger inflammation, and remove debris from cells and tissues. This system must be carefully regulated so it targets only unwanted materials and does not attack the body's healthy cells. Complement factor I and several related proteins protect healthy cells by preventing activation of the complement system when it is not needed.

Hémophilie
Hémophilie is a rare bleeding disorder that affects your ability to make a clot. The blood contains substances called clotting factors that work with platelets to form a clot. When you injure yourself the clot stops you bleeding. Haemophilia is a condition where there is a deficiency of clotting factors, so people with this condition usually have.

Puis-je prendre Apixaban et Bisoprolol ensemble ?
There is no direct interaction between apixaban and bisoprolol. They work in different ways and do not interfere with how the body processes each other. Why this happens Apixaban est un anticoagulant (blood thinner) that works by blocking a clotting factor called Factor Xa. Bisoprolol is a beta-blocker that slows the heart rate and lowers blood.
