Definition: Antibodies, specifically antibodies produced during an immune response, are used in anti-cancer drugs to kill cancer cells. Definition: The word "antilysis" refers to a process by which the body's immune system destroys harmful or damaged substances without harming healthy tissue. Antimalarial drugs, such as artemisinin and azithromycin, work by targeting specific proteins that are responsible for transmitting viral pathogens to target cells. This process involves recognizing, destroying, and recycling these antigens in the body. Antibodies produced during an immune response help neutralize and destroy cancer cells (antitumor immunity), which helps prevent or treat cancer.
