  • Innate Immune System

    Innate immunity constitutes the first line of defense and is fundamental for the recognition and the initiation of an inflammatory response against microorganism. Maintenance of homeostasis is a primary function of the innate immune system and it is achieved through immune surveillance by pattern recognition receptors (PRRs), such as Toll-like receptors (TLRs) and nucleotide-binding domain leucine-rich repeat containing receptors (NLRs). The PRR’s are predominantly expressed by cells of the myeloid lineage. TLRs and NLRs are distributed throughout the gastrointestinal mucosa mostly being expressed in the epithelium and in lamina propria cells. The gastrointestinal mucosa surfaces are in constant interaction with a wide variety of commensal…

  • The Innate Immune System

    The innate immune system is the defense mechanism that is activated immediately or shortly after the body is exposed to invading microorganisms.1 This system is quick in response and does not have a memory, meaning it doesn’t need previous exposure to the foreign microbe’s antigen before it can be activated.2 The adaptive immune system consists of antigen-specific immune responses.2 This system is slow in response because after it is exposed to an antigen, it needs time to process the antigen…

  • Summary: The Innate Immune System

    The system produces a number of substances include cationic antimicrobial peptides (CAMPs) such as defensins, bacteriolytic enzymes such as lysozyme etc. The production of these substances ensures that the microorganisms are destroyed before they get an opportunity to cause infections [4]. However, S. aureus has developed mechanisms, which enhance the evasion of the host immune system. The host’s body produces effector proteins after microbial invasion; nevertheless, S. aureus produces molecules…

  • Innate Immune System Case Study

    1. The innate immune system, also considered the first line of defense, is made up of different mechanisms that protect the host from infecting organisms. This system allows for immediate response to infection, and is found in all classes of plant and animal life. Though the innate immune system does provide immediate defense against an infecting agent, it does not provide long term protective immunity to the host, therefore it does not have memory. The innate immune system utilizes protective…

  • Innate Vs Adaptive Immunity Case Study

    adaptive immunity. Discuss at least one specific condition that can impair the immune system’s ability to function normally The immune system defends the body two different ways innate and adaptive immunity. Innate immunity is the body’s natural way to fight against disease or pathogens consider this the body’s first line of defense against invasion. Innate immunity recognizes when something is not native to the body and attacks microbes preventing the infection from spreading. Innate…

  • Periodontitis Research Paper

    Periodontal diseases generally refer to common inflammatory disorders known as gingivitis and periodontitis, which are caused by a pathogenic microbiota in the subgingival biofilm that trigger an inflammatory response that activate the immune system. Biochemical mediators are biologically active compound, released by the immune cells as a response of the body to eliminate pathogenic bacteria when the periodontium is infected. These mediators responsible to initiate the inflammatory response are…

  • Celiac Disease Case Study

    protein distinction in the body, separating pathogenic proteins from innate proteins. Specific gene variants of HLA-DQA1/HLA-DQB1 (HLA-DQ2 or HLA-DQ8), trigger the immune system when exposed to gliadin protein, a derivative of gluten, and cause inflammation in the small intestines. HLA-DQ2 or HLA-DQ8 have been found in almost all genetically tested CD individuals, with HLA-DQ2 being much more prevalent (NLM, 2016). If someone tests negative for HLA-DQ2 and HLA-DQ8 during a diagnostic biopsy for…

  • Essay On Human Immune Response

    The human immune response is a complex, layered system that uses multiple defense mechanisms which function in harmony to protect the body from infection and illness. There are two main types of immune response, the innate and acquired, and while these responses are related and sometimes overlap, they use separate processes to defend against invaders. Working as a whole, innate and acquired immune responses protect the body from infectious organisms. Infectious organisms that can cause disease…

  • The Immune System In The Human Body

    Immune System(Remove) What does immune system means? The immune system is the one of necessity system in the body. It helps the body defend against every foreign body that causes disease for body. The immune system is getting stronger and stronger while it destroys disease.

In other words, the immune system…

  • Adaptive Immunity Essay

    On basic note Presence Innate immunity is something already present in the body. Adaptive immunity is created in response to exposure to a foreign substance. Specificity Non-Specific Specific Response Fights any foreign invader and rapid Fight only specific infection and slow(1-2 wks) Potency Limited and Lower potency High potency Time span Once activated against a specific type of antigen, the immunity remains throughout the life. The span of developed immunity can be lifelong or short.…
