Lecture 3. Immunity – Innate Immunity - Acquired Immunity, Active - Passive Immunity. Unlike the innate immune system, the acquired immune system is highly specific to a particular pathogen. Mechanisms of innate immunity work collectively to inhibit the entry of a pathogen or eliminate it, preventing infection. Definition: The defense mechanisms that are non-antigen specific and immediately come into play on the antigen’s appearance in the body. Interferons protect the uninfected cells from further infection. Most viruses establish their infection by suppressing host innate immune response, a phenomena termed viral evasion (see Table 5.4). 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.

All of us have innate defense systems that are functional at birth. Acquired immunity includes both humoral immunity and cell-mediated immunity and will be the topic of Unit 6. Mechanism of innate immunity: Anatomical barrier It is acquired due to the injection of ready-made antibodies into the body. Active immunity: Passive immunity: The immunity is provided by the antibodies produced in the body. The innate and the adaptive immune system efficiently cooperate to protect us from infections. The ancient innate immune system, dating back to the first multicellular organisms, utilizes phagocytic cells, soluble antimicrobial peptides, and the complement system for an immediate line of defence against pathogens. Innate Immunity. There are two major types of immunity: innate or natural or nonspecific and acquired or adaptive. First line of defence Lacks memory -unchanged with rpt Ag exposure Develops earlier than acquired responses Primitive response Innate immunity is comprised of External barriers eg skin + Soluble mediators of inflammation eg cytokines + Cells eg phagocytes + Receptors to recognise the presence of a pathogen or injured tissue & results in inflammation Innate immunity lecture 1. The innate and the adaptive immune system efficiently cooperate to protect us from infections. Macrophages release cytokines TNFα, In this case the immune defense is acquired. IgM in plasma, for early response, It is also known as acquired immunity. Acquired Immunity here can take in two forms it can be actively acquired or passively acquired. Matee Department of Microbiology and Immunology School of Medicine 2. Innate immunity is non-specific type of defense. This is because passively acquired immunity involves the uptake of antibodies which only lives for several weeks or 4 months at max in … ; Pathogen Associated Molecular Patterns (PAMPs) are conserved molecular structures of bacteria, viruses and other pathogens that bind to PRRs. It consists of cellular and biochemical defense mechanisms that are in place even before infection and are poised to respond rapidly to infections. Mast cell (tissue): defence against Internalises Ag, presents on MHC2, (c) It is fast but lasts only for few days. Although innate systems predominate immediately upon initial exposure to foreign substances, multiple bridges occur between innate and acquired immune system … Nuttig? Difference Between Active Immunity and Passive Immunity. Innate immunity (also called natural or native immunity) provides the early line of defense against microbes.

Acquired immunity - acquired immunity is a resistance develop for specific antigen or resistance acquired by an individual during life time. It occurs when antibodies are directly given into the body. The innate immune system provides the first line of host defense against microbes, before adaptive immune responses have had sufficient time to develop. Innate immunity (also called natural or native immunity) provides the early line of defense against microbes. Immunity can be classified into two groups – (i) innate immunity, and (ii) acquired immunity. Alternatively, innate immunity holds an infection in check until the slower adaptive immune response can be mounted. (ii) It consists of four types of barrier system that prevent the entry of pathogen or foreign element in to the body. memory, o The two types of immunity have been discussed in detail below – Innate Immunity. The word innate indicates that you are born with a feature. virus-infected cell and bacteria, Basophil (blood): defence against Innate Immunity: It refers to all the defence elements with which an individual is born and always available to protect the body. Active immunity: Passive immunity: The immunity is provided by the antibodies produced in the body. Immunity is the state of resistance exhibited by the host body against any foreign particle or microorganisms. It is a non-specific type of defence system.
