This is also known as an “acquired” (learned) or specific immune response.īecause the adaptive immune system is constantly learning and adapting, the body can also fight bacteria or viruses that change over time. The adaptive (specific) immune system makes antibodies and uses them to specifically fight certain germs that the body has previously come into contact with. The main job of the innate immune system is to fight harmful substances and germs that enter the body, for instance through the skin or digestive system. It mostly fights using immune cells such as natural killer cells and phagocytes (“eating cells”). The innate immune system provides a general defense against harmful germs and substances, so it’s also called the non-specific immune system. Both of these subsystems are closely linked and work together whenever a germ or harmful substance triggers an immune response. There are two subsystems within the immune system, known as the innate (non-specific) immune system and the adaptive (specific) immune system. Our work highlights the important role that the immune system plays in mediating the adaptation of muscle to regular exercise, Lee said. It then attacks healthy, harmless cells in the body. These findings demonstrate how immune signaling works in coordination with the metabolic pathway to support the body’s needs during prolonged physical activity. Sometimes the immune system mistakenly thinks that the body's own cells are foreign cells. ![]() But those proteins don’t usually trigger the immune system to fight the cells. The body’s own cells have proteins on their surface, too. Then, if it comes into contact with the germ again, it recognizes the germ straight away and can start fighting it faster. ![]() Once the body has come into contact with a disease-causing germ for the first time, it usually stores information about the germ and how to fight it. When these antigens attach to special receptors on the immune cells (immune system cells), a whole series of processes are triggered in the body. Examples of antigens include the proteins on the surfaces of bacteria, fungi and viruses. The immune system can be activated by a lot of different things that the body doesn’t recognize as its own.
