Difference between Innate and Adaptive Immunity
Innate immune system
Clinical and Basic Immunodermatology pp Cite as. The skin immune system is the complex network of cells that are able to mount an immune response in the skin. The immune response can be divided into innate and adaptive arms. This is highly relevant to both systemic immunity, as well as immunity in the skin. The innate immune system responds rapidly to microbial insults, but is thought to have no memory or specificity. The adaptive immune system, composed of B lymphocytes and T lymphocytes, requires more time to respond to a threatening challenge to the host, but is responsible for long-lasting memory and specificity, and the development of an effector pool of lymphocytes for humoral or cell mediated immunity. Virtually all cells that reside in the skin play some role in the function of the skin immune system.
What happen if foreign invader attack the body to the second time in innate immunity? How innate immunity will response? An Ag can specifically bind to an Ab molecule. An Ag i.
Complement and its role in innate and adaptive immune responses
Defense against microbes is mediated by the early reactions of innate immunity and the later responses of adaptive immunity. Figure 1, 2; Table 1. Innate immunity also called natural or native immunity provides the early line of defense against microbes. It consists of cellular and biochemical defense mechanisms that are in place even before infection and are poised to respond rapidly to infections. The mechanisms of innate immunity are specific for structures that are common to groups of related microbes and may not distinguish fine differences between microbes.
The innate immune system is one of the two main immunity strategies found in vertebrates the other being the adaptive immune system. The innate immune system is an older evolutionary defense strategy, relatively speaking, and is the dominant immune system response found in plants , fungi , insects , and primitive multicellular organisms. Anatomical barriers include physical, chemical and biological barriers.
