Innate immunity (also called natural or native immunity) provides the early line of defense against microbes. 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 Innate and adaptive immunity 15. Although innate systems predominate immediately upon initial exposure to foreign substances, multiple bridges occur between innate and acquired immune system … Unlike the innate immune system, the acquired immune system is highly specific to a particular pathogen. 34.1 Overview of Adaptive Immunity 1. (i) It is present from the time of birth and inherited from parents. (A) Innate or Natural or Nonspecific Immunity (L. innatus = inborn): Innate immunity is inherited by the organism from the parents and protects it from birth throughout life. Innate immunity (also called natural or native immunity) provides the early line of defense against microbes. It is also known as acquired immunity. Acquired immunity can also be classified as: It is the immunity developed by the body, when it is exposed to the antigens. Agenda. The mechanisms of innate immunity are specific for structures that are common to groups of related microbes and may not distinguish fine … Immediate innate immunity begins 0 - 4 hours after exposure to an infectious agent and involves the action of soluble preformed antimicrobial molecules that circulate in the blood, our found in extracellular tissue fluids, and are secreted by epithelial cells. Acquired immunity or adaptive immunity is the immunity that our body acquires or gains over time. in tears, fatty acids in sweat, o infected cell; phagocytoses, o Table of differences: IgM in plasma, for early response, Innate immunity lecture 1.

Acquired Immunity: Acquired immunity is not inheritable, with the exception of one form of passive immunity acquired by a baby from its mother during gestation. 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. The ability of the immune system to adapt itself to disease and to generate pathogen-specific immunity is termed as acquired immunity. Acquired immunity includes both humoral immunity and cell-mediated immunity and will be the topic of Unit 6. Innate immunity consists of various barriers which prevent the entry of microorganisms into the body. Difference between innate and acquired immunity.

Innate immunity was already talked about in last week’s notes under ‘First Line of Defence’ and ‘Second Line of Defence’. Innate system: physicochemical, humoral, cellular components, ·         Innate immunity can be divided into immediate innate immunity and early induced innate immunity. Macrophages release cytokines TNFα, Steps your body takes to protect you from pathogens; How does you body recognize pathogens? Active immunity and passive immunity are two types of adaptive immunity. Acquired immunity is highly adaptive and is capable of specifically recognizing and selectively eliminating foreign microorganisms and macromolecules, i.e., antigens. immune response, o It is used when the immune response has to be faster. in tears, fatty acids in sweat, Macrophages release cytokines TNFα, Acid in the stomach, saliva in the mouth, tears from the eyes, etc., prevent the entry of microbes. 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.
