Innate Defense System
Pathogens such as bacteria, viruses, fungi, and parasites can respond to antibodies produced by the immune system. Antibodies work by binding to specific antigens on the surface of pathogens, marking them for destruction by other immune cells. This antibody response is a key component of the adaptive immune system's defense mechanism against infections.
No, T cells respond to antigens by directly destroying infected cells or by producing cytokines to help coordinate the immune response. Complements are a group of proteins that are part of the innate immune response and are mainly secreted by macrophages and other immune cells to help enhance the immune response.
When dead or weakened microbes are introduced into a healthy body, the immune system recognizes them as foreign invaders. This triggers an immune response, leading to the activation of various immune cells and the production of antibodies. This process helps the body to "learn" how to respond to similar live pathogens in the future, effectively preparing the immune system for potential infections. This principle is the basis for many vaccines, which use killed or attenuated microbes to build immunity.
The macrophages are typically the first cells to detect and respond to invading germs in the body. They are part of the innate immune system and are able to recognize and engulf pathogens to initiate an immune response.
Memory B cells are only active during a specific immune response. They are a type of white blood cell that "remembers" previous pathogens the immune system has encountered and can quickly respond to future infections by producing specific antibodies.
lymph
Tolerance exists when the immune system does not respond to a particular antigen. All cells and tissues in the body contain antigens that normally do not stimulate an immune response. The immune system is said to exhibit tolerance toward such antigens.
The immune system is a system in the body. It begins with the letter i.

Response cells are cells that respond to the immune system and react to diseases.

An autoimmune response is always disadvantageous to an individual. This is because the person's immune system begins to attack itself.
