The immunity which occurs by birth is called innate immunity. Innate immunity consists of external barriers formed by the skin and mucous membranes, plus a set of internal cellular and chemical defenses that defend against microbes that breach the external barriers. It is a non-specific type of defence system.

A prominent difference between active and passive immunity is that active immunity is developed due to the production of antibodies in one’s own body, while passive immunity is developed by antibodies that are produced outside and then introduced into the body. It occurs when antibodies are directly given into the body. This resistance plays a major role in the prevention of infectious diseases.

Innate Immunity. Since actively acquired immunity involves the production of memory T cells and memory B cells, such immunity to the pathogen will last longer than passively acquired immunity. There are two major types of immunity: innate or natural or nonspecific and acquired or adaptive. Acquired immunity includes both humoral immunity and cell-mediated immunity and will be the topic of Unit 6. proliferation, o Difference between innate and acquired immunity. How the vascular cambium is responsible for secondary growth? (ii) It consists of four types of barrier system that prevent the entry of pathogen or foreign element in to the body. It is an artificial immunity. It is a non-specific type of defence system. Matee Department of Microbiology and Immunology School of Medicine 2. The innate immune system is the most evolutionarily conserved arm of the immune system and it generates rapid, non-specific inflammatory responses in response to signals from Pattern Recognition Receptors (PRR). It is the more specific component of immunity. Special types of cells in our body, which kill the disease causing agents. Answer Now and help others. The main difference between innate and acquired immunity are as follows – Immunological memory – Acquired immunity has immunological memory while innate immunity does not. It is an artificial immunity. IL1, IL6, IFN, Local effects: vasodilatation, capillary In contrast to innate immunity, on re-exposure the responses are faster, more vigorous and more specific. The innate and the adaptive immune system efficiently cooperate to protect us from infections. Innate Immunity. parasites, role in allergy, o Cells which are virus-infected, release types of protein called interferon’s. The innate immune system provides the first line of host defense against microbes, before adaptive immune responses have had sufficient time to develop. cellular components, ·         Acquired Immunity here can take in two forms it can be actively acquired or passively acquired. (i) It is present from the time of birth and inherited from parents. Innate immunity (also called natural or native immunity) provides the early line of defense against microbes. memory, Internalises Ag, presents on MHC2, Complementary Roles of Innate &Innate Vs Acquired Response:Innate: Rapid, non-specific response, non-memoryAcquired:Longer term, more specific response, more efficient, Memory,AcquiredImmunityRapid and greater response to subsequent infection by the same organism,complementary to the innate responses. INNATE AND ACQUIRED IMMUNITY 9 9-3 INNATE IMMUNITY The healthy individual is protected from potentially harmful micro-organisms in the environment by a number of effective mechanisms, present from birth, that do not depend upon prior exposure to any par-ticular microorganism. 34.1 Overview of Adaptive Immunity 1. difference between innate and acquired immunity Acquired/Adaptive Immunity.

The innate immunity and acquired immunity work together to eliminate pathogenic microorganisms and other foreign agents. It prevents the entry of the pathogens of the body. Innate immunity consists of various barriers which prevent the entry of microorganisms into the body. Although innate systems predominate immediately upon initial exposure to foreign substances, multiple bridges occur between innate and acquired immune system … ADVERTISEMENTS: In this article we will discuss about innate and acquired immunity. Innate immunity is not stand alone but interacts with adaptive immunity - Innate immunity primes adaptive responses - B cells are ‘primed’ by activated complement - Th1 cell differentiation needs pro-inflammatory cytokines - Adaptive responses enhance innate ‘effectors’ - Th1 promote macrophage phagocytosis + neutrophil killing - Antibodies act as opsonins and some activate complement Antigens - substances that are foreign to the body – usually proteins present on the surfaces of whole organisms (like bacteria or viruses) or on parts of organisms (like pollen) Concept Map for Innate Versus Adaptive Immunity Compare and contrast how innate immunity and adaptive immunity are typically initiated in response to microbes.
