Innate immune system

The human leukocyte antigen complex (HLA) aids in 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…

The host immune response is important in maintaining the health of periodontal tissues. The presence of pathogens in periodontal pockets will activate innate and adaptive immune responses in an attempt to clear the pathogenic threat as well as promote tissue homeostasis. However, the persistent presence of pathogens can cause the continuous activation of innate and adaptive immune responses; which in turn causes inappropriate inflammatory mediator (cytokine, chemokine, antimicrobial proteins…

surface of the skin or by entering through some other portal of entry; (2) attach itself to a host cell and (3) evade the body’s defense mechanisms long enough to produce harmful changes. In this research paper, I will discuss the differences between innate and adaptive immunity along with the chemical and physical factors that are involve in these immunities. It is easy to cluster the structures, cells, and chemicals that act against pathogens into two main lines of defense, each of which…

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 cytokines, prostaglandins, and…

Discussion of Relevant Literature In terms of understanding the role of the GI tract in immune response, articles 1 through 3 provided the best information. When trying to understand mechanisms or functions of a body system, it is important to discuss the implications of these mechanisms or functions in relation to what is relatable to the human body. Article 1 explains the role of GALT in the GI tract in relation to allergies, and goes further by discussing celiac disease, which is a common…

got sick too all the time. Thinking about it having him exposed to those germs and bacteria will in the end build a strong immune system for him. So, immunity refers to resistance to disease. The innate defense system and the adaptive defense system. The innate defense system is when you are born with it you just have it. And adaptive means you get it later. The innate system has surface barriers, and mucous membranes that will trap pathogens. Basically, nothing particularly different these are…

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…

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. It takes experience from disease which it is destroyed. The immune system is defined as “the system that protects your body from diseases and infections” in Merriam-Webster dictionary. In other words, the immune system…

Introduction The human body is populated by a large aggregate of microbes on the skin as well as many mucosal surfaces. They are composed of mainly bacteria, fungi, and protozoa. These commensal microorganisms live in the human body in symbiosis. Microbiota play a functional role in the health and disease of an individual. Roughly there are around 1012 bacteria found on the skin, primarily staphylococci and corynebacteria, and 1010 found in the mouth, primarily, streptococci, lactobacilli.1 But…

(neutrophils and monocytes for innate immunity and lymphocytes for adaptive immunity) to enter the area and clean up. This then allows for tissue repair to occur. The main element in the initiation of inflammation is NFKB- leading to the activation and release of cytokines and effector cells. However, there is also neuroinflammation to consider. It is not a process so dissimilar to what happens in the periphery as there is cross talk between the immune and nervous systems. The cross talk which…
