The Role of Antibodies from Cellular Immune Responses in the Complement System

Antibodies in Immune Responses

Antibodies are key components of the immune system's defense mechanism. They are produced by B cells in response to the presence of foreign substances in the body.

The Complement System

The complement system is a part of the immune system that enhances the ability of antibodies and phagocytic cells to clear pathogens. It is composed of a complex network of proteins that work together to identify and eliminate foreign invaders.

Antibodies and the Complement System

Antibodies generated by cellular immune responses play a crucial role in the activation of the complement system. They are specifically involved in the classical pathway of complement activation.

Activation Pathways

There are three main pathways through which the complement system can be activated: the classical pathway, the alternative pathway, and the lectin pathway.

Role of Antibodies

Antibodies from cellular immune responses are utilized in the classical pathway of the complement system. They bind to pathogens, which triggers a cascade of complement protein activation leading to the destruction of the pathogen.
