Immunology has its origins in the study of how the body protects itself against infectious diseases caused by microorganisms, such as bacteria, viruses, protozoa, and fungi, and also parasitic organisms, such as helminth worms. The immune system (or immunity) can be divided into two types - innate and adaptive immunity. Immunologic defenses in vertebrates consist of two immunologic subsystems—innate and adaptive. 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 and in extracellular tissue fluids. Innate Immunity The innate immune response is the body’s 1st line of defense and includes: 1) physical barriers between inside & outside • the skin and the mucous membranes of the digestive, respiratory and genito-urinary tracts • all substances secreted at these barriers and all of the normal microbiota that live on these surfaces You can change your ad preferences anytime. Pattern recognition receptors (PRRs) play a crucial role in the proper function of the innate immune system.PRRs are germline-encoded host sensors, which detect molecules typical for the pathogens. The adaptive immune response is more complex than the innate. Overview of Specific (Adaptive) Immunity •Three major functions –recognize nonself –respond to nonself Berkembangsepanjanghidup. and antigen specific adaptive responses (antibody, effector T lymphocytes). The internal mucosal tissues (e.g. The immune system can be simplistically viewed as hav-ing two “lines of defense”: innate immunity and adaptive immunity. due largely to the immune system. Innate Immunity. For much of the past 30 years, immunologists and microbiologists have studied innate and adaptive immunity in isolation. Innate Immunity. View Innate Immunity.ppt from IFSN 303 at Bahauddin Zakaria University, Multan. Alternatively, innate immunity holds an infection in check until the slower adaptive immune response can be mounted. ; Pathogen Associated Molecular Patterns (PAMPs) are conserved molecular structures of bacteria, viruses and other pathogens that bind to PRRs. Principles of tumour immunology. 1. The innate immune system controls the early stages of infection. 14: Innate immunity is always kept on. Eg. Innate immune mechanisms also clear host cell and microbial debris from the body. Looks like you’ve clipped this slide to already. Central University Of Kerala. HDT 2:1 – Semester 2.

Innate Immunity • When barriers to infection are compromised, such as a graze or a reduction in mucociliary escalation, the innate immune response is initiated. Some innate immune mechanisms are completely non-induced and non-specific, whereas others are inducible and involve broad pattern recognition mediated by pattern recognition molecules (P… Innate Immunity (natural/native): Immediate Innate Immunity The innate immune response is the body’s 1st line of defense and includes: 1) physical barriers between inside & outside • the skin and the mucous membranes of the digestive, respiratory and genito-urinary tracts • all substances secreted at these barriers and all of the normal microbiota that live on these surfaces Innate Immunity (Non-specific) 2.

And even in the nonspecific immune system, we subdivided that into kind of the first line barriers. 18 Innate Immune System . Innate immunity represents the first line of defense to an intruding pathogen. Innate and Adaptive Immunity Innate immunity is the immunity one is born with and is the initial response by the body to eliminate microbes and prevent infection. M.Sc. Menghancurkan zat asing. The key difference between innate and adaptive immunity is that innate immunity is a fast immune response that provides the first line of immunological defence against infections while adaptive immunity is a slow immune response mediated by the T and B lymphocytes.. Ana410(2) Innate Immunity PPT. The immune system is composed of two closely collaborative systems, an innate and an adaptive system. Outline the localization of B and T cells during development 2 . If a pathogen persists, the adaptive immune system will engage the pathogen with specificity and memory. The potency of adaptive immunity is very high. INNATE 6 hours 12 hours 1 week TIME ADAPTIVE Cancers grow and spread when tumor cells evade detection by the immune system. Natural passive immunity: IgG antibody produced in mother cross placenta and protects fetus up to 6 month old age. How do you know how to breathe?

Eg. If these defences are breached, the acquired immune system is called into play. Adaptive immunity refers to antigen-specific immune response. Explain the types of Immunity? These changes are necessary for full immune system activation. 34.1 Overview of Adaptive Immunity 1. Anti-venom, Rabies vaccine (* it is not a vaccine, it is preformed anti rabies antibody) Immunity and its types: Innate and Acquired immunity Innate immunity is the first line of defence against infectious agents, and most potential patho-gens are checked before they establish an overt infec-tion.
