Innate vs Adaptive Immunity. The major function of the immune system is to defend the host against pathogens and toxins, a task which is essential to any organism. Rather than forming into organs, the cells of the immune system are composed primarily of individual cells, and they spread throughout the body. However, the response to a second attack is more rapid, and it is the basis for vaccines. The innate system is mainly composed of eosinophils, monocytes, macrophages, natural killer cells, tor-like receptors (TLRs), and a series of soluble mediators such as complement system. Adaptive Immunity. The adaptive or specific immune system mainly attacks the specific invaders Adaptive immunity refers to antigen-specific immune response. The adaptive immune response is more complex than the innate. The antigen first must be processed and recognized. Once an antigen has been recognized, the adaptive immune system creates an army of immune cells specifically designed to attack that antigen. Adaptive immunity also includes a memory that makes future responses against a specific antigen more efficient. Features of an Immune Response. An immune response is generally divided into innate and adaptive immunity. Innate immunity occurs immediately, when circulating innate cells recognize a problem. Adaptive immunity occurs later, as it relies on the coordination and expansion of specific adaptive immune cells. An effective vaccine will optimally activate both the innate and adaptive response. An immunogen is used to activate the adaptive immune response so that specific memory cells are generated. Confidence votes 25. The innate system is a first line response after an infection happens. The adaptive system is when an immune cell (likely macrophages) show the pathogen to a lymph node and from there B cells make antibodies specifically for that pathogen. The innate system is non specific, but acquired is specific. The Innate Immune Response. The innate immune response is a non-specific response, meaning it is activated simply by the presence of a pathogen. Cells of the innate system respond to pathogens in a very general, generic way. Their response does not change, regardless of the type of pathogen involved. Another key feature of the innate immune response is that it has no memory, and it cannot trigger the development of memory. This first part of a series about different arms of the immune response looks at the innate and adaptive immune responses. slide 1 of 4. The various arms of the immune system can be categorized in several different ways. One of these is in terms of • The response of the innate system is rapid while that of the adaptive immunity is slow (Over 1-2 weeks). • The innate system has limited and lower potency. In contrast, the adaptive system has high potency. • The innate system recognizes a broad range of pathogens, but it cannot make fine distinctions. However, the response to a second attack is more rapid, and it is the basis for vaccines. The innate system is mainly composed of eosinophils, monocytes, macrophages, natural killer cells, tor-like receptors (TLRs), and a series of soluble mediators such as complement system. Adaptive Immunity. The adaptive or specific immune system mainly attacks the specific invader
