T Cells and Antibodies Fight Pathogens

T Cells and Antibodies Fight Pathogens

T lymphocytes or T cells are one of the most amazing devices designed into your body. T cells are critical to defending your body against viral invaders (pathogens). T cells are white blood cells that work with proteins called antibodies to recognize and fight pathogens. When your immune system detects a pathogen, your body starts producing T cells and antibodies to fight it.

T cells are created in the bone marrow and then travel to the thymus gland right in front of the heart, where they mature. The T cells then circulate in the blood and lymphatic system, searching for pathogens by detecting the antigens on their surfaces. When they find pathogens, T cells and antibodies work to neutralize them, protecting your cells.

If a virus is new, it may take time for your body to generate the necessary T cells and antibodies to fight it. That’s where vaccines step in to give your body a head start so that if you get infected by a new pathogen, your body is prepared and ready to fight it. After clearing the infection, some of the T cells remain in case it returns.

The amazing immune system is the product of careful design and not some kind of accident. The more complexity we see in a system, the less likely it is a product of blind chance. The statement in Psalms 139:14 describes the wonder of T cells and antibodies: “I will praise you, Lord, for I am fearfully and wonderfully made: marvelous are your works and that my soul knows full well.”
