CDC (Complement-dependent Cytotoxicity)

Complement-dependent cytotoxicity (CDC) is a process where the immune system uses a part called the complement system to destroy targeted cells, such as infected or cancerous cells. When an antibody binds to a cell's surface, it activates the complement proteins, which then create a chain reaction leading to the formation of a pore in the cell membrane. This pore causes the cell to break apart and die. CDC is an important mechanism the immune system employs to eliminate threats, and it is also utilized in certain medical treatments, like antibody therapies for cancer.
