From Wikipedia, the free encyclopedia

The Complement system is generated to regulate self protection from infection. The overall Complement system is composed of protein groups that collaborate in destroying foreign invaders, which ultimately remove debris from cells and tissues. When the body detects a foreign invader, the body signals the Complement system and the Complement component 2 protein attaches to Complement system 4 resulting in an immune response. Complement component 2 protein is critical for regulating the body's immune response.

Complement Component 2 Deficiency

[edit]
Complement C2 is a protein that in humans is encoded by the C2 gene.

In the Molecular Biology, the deficiency of Complement Component 2 is a disorder that causes a major effect in the immune system, resulting in a form of immunodeficiency. This effect results in an inability to protect the body against any foreign invader. Complement component 2 deficiency is also connected with an increased risk of developing autoimmune disorders, such as systemic vasculitis.
