HealthWhat Are Four Functions of Antibodies By Chris GreenwaltyNovember 26, 2022 Antibodies play a crucial role in defending against infection. These molecules attach to foreign invaders, such as pathogens and toxins, which enables them to recognize the body’s own tissue and destroy it. The process is called antibody dependent cell mediated cytotoxicity (ADCC). There are two types of antibody receptors on a white blood cell: Fc receptors (FcR), which act as antigen binding sites, and complement receptor 2 (CR-II), which activate an intracellular signal for the destruction of the target cell. They can also interact with T lymphocytes to help regulate the activity of the latter. You need a healthy balance between your humoral immunity and cellular immunity in order to fight infections effectively. Bluegen antibodies This is because if you are too weak in one arm, this will affect the other. For example, a person who has low levels of B lymphocytes won’t be able to produce sufficient amounts of IgG antibodies, and thus may not respond well to vaccinations. What Are the 4 Functions of Antibodies Quizlet Antibodies are proteins that your body produces to fight against foreign invaders. Antibodies can be found in many different parts of the human body. For example, they help protect the lungs from bacteria, the skin from germs, and the digestive system from food particles. There are four main functions of antibodies. First, they act like a defense mechanism. This means that when you get sick, your immune system will produce more antibodies to combat the infection. Second, they can also recognize and destroy harmful cells. Third, they can neutralize viruses and other pathogens. Finally, they can trigger an allergic reaction.
