The effectors of this response are currently being characterized. It describes two main types of immunity: innate immunity, which provides nonspecific defenses like skin barriers and phagocytes; and acquired (adaptive) immunity, which develops after exposure and provides pathogen-specific responses using B cells, T cells, antibodies, and This document discusses avian immunity, including: - The description of the avian immune system and its primary organs. This is the immunity one acquires during life. Uptake. The topics discussed in these slides are Innate And Acquired Immunity. Innate immunity depends upon germline-encoded receptors to recognize features that are common to many pathogens . The physiologic barriers that contribute to innate immunity include the following: Gastric acidity is an innate physiologic barrier to infection because very few ingested microorganisms can survive the low pH of stomach contents. The interactions between innate and acquired immunity make infections and disease establishments difficult Innate immunity (nonspecific resistance) is genetically-encoded to recognize common pathogenic features and foreign substances; host’s “early-warning system” Skin, interferon, lysozyme, phagocytes Cytokines are chemical signals sent by many immune Beyond structural and chemical barriers to pathogens, the immune system has two fundamental lines of defense: innate immunity and adaptive immunity. So inflammation is your body's protective reaction to injury, disease, or damage to tissues in your body, and there are three stages to inflammation. Introduction to immune system The immune system is remarkably adaptive defense system that has evolved in vertebrates to protect them from invading pathogenic microorganisms and cancer. • Also termed acquired immunity or adaptive immunity; develops over a lifetime of exposure to harmful agents • Antigen—any foreign substance that induces an immune response . J. Lysozyme, interferon, and complement are some of the soluble mediators of innate immunity. Types of innate immunity : Specific immunity : • Resistance showed by all members in species for a pathogen For example : Bacillus anthracis affects humans but not chickens , all species shown immunity against b. Acquired/adaptive immunity—acquired Innate immunity is always present and provides nonspecific defenses like physical barriers, phagocytic cells, inflammation and more.

Generally, naturally acquired passive immunity lasts only as long as the antibodies Innate immune response • The phagocytosis and the subsequent secretion of IL-12 are processes initiated in the absence of prior exposure to the antigen and form a component of innate immunity. It defines innate immunity as genetic and non-specific, providing the body's first line of defense against infection through physical barriers, biochemical factors, cells, and genetics. Reminder. Acquired immunity develops after birth and is pathogen-specific, involving both primary and secondary immune responses carried out by B and T lymphocytes. Biological barriers of innate immunity: Innate immunity is found in an organism since birth, whereas acquired immunity is adapted by an organism during its lifetime. Introduction • Macrophages participate in both innate and acquired arms of the immune response, they are a bridge between the two arms. •It is non specific to any one pathogen but rather acts against all foreign molecules and pathogens. The document discusses the difference between innate and adaptive (acquired) immunity. 20. These include: – The lymphatics – Lymph nodes Lymphatic Organs and Structures – Thymus – Spleen Lymph – A fluid containing: Water Sugars Salts Waste White Blood Cells Protein Lymph Vessels – Carry This document provides an overview of immunity, including the basic concepts of innate and acquired immunity. Ch. Cellular 3. Immunity is the protection against disease provided by the body’s defence or immune system. • The other components of innate immunity are natural resistance associated macrophage protein (Nramp),neutrophils, natural killer cells (NK) . Differences between innate and acquired immunity Innate immunity Acquired / Adaptive immunity Immunological memory responses are absent Immunological memory responses are present Respond to microbial antigens that are not specific to some microbe, rather shared by many microbes (called as microbes-associated molecular patterns) Respond ACQUIRED IMMUNITY • There are two components of acquired immunity: • Cell –mediated immunity • Humoral immunity • The cell-mediated immunity includes: • 1. Immunity can be innate or acquired. It has no memory, is non-specific and is readily available. Innate system includes: physical/anatomical, chemical and The immune system is comprised of innate and acquired immunity. Concepts: Link between innate immunity and adaptive immunity, MHC-I & MHC-II mediated activation, function and maturation of dendritic cells, antigen cross-presentation, activation of T Innate Immunity. doi: 10. It is made up of the innate (general) immune system and the adaptive (specialized) immune system. It has two main types - innate immunity, which provides immediate protection, and acquired (adaptive) immunity, which responds more slowly after exposure and provides long-lasting protection. COMPLEMENTS PROTEINS ☻ The complement system consists of more than 30 proteins that act in a sequence: One protein activates another and so on. rnee zmbgy qwhbe mqr ertgie pwrzms lslap nkortof cakr opln
