Elie Metchnikoff's Cellular Theory

Decent Essays
Elie Metchnikoff, whose original name was llya llich Mechnikoff was a Russian scientist born on May 16, 1845. In 1883, he presented “The Curative Forces of the Organism,” Metchnikoff’s theory of phagocytes. Phagocytes (eating/ devouring cells), such as white blood cells or leukocytes, work as our front-line defense against infections in most animals including humans. This work formed the basis of Metchnikoff’s cellular theory of immunity in 1892
. According to Metchnikoff, under appropriate conditions, protector cells within an organism would engulf, mount, attack and ingest foreign bodies, such as bacteria to protect us from invading matters. This phenomenon known as Phagocytosis would become a fundamental part of our immune response system.

    According to Schouten et al (2008), sepsis involves the activation of the coagulation cascade coupled with down-regulation of anticoagulation and fibrinolysis. An intricate link between inflammation and coagulation exists within the body (Neligan, 2006). When a pathogen is present in the bloodstream or when tissue injury occurs, an inflammatory response occurs. The response causes a stimulation of the immune system to produce interleukin-1 (IL-1), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNFα) (Neligan, 2006). These cytokines are the main catalysts of the inflammatory response and cause the release of several agents including, interleukin-8, histamine, kinins, serotonin, selectins, and neutrophils.…

    The first main defense of the immune system is known as barriers which is the first line of defense. Barriers Neutralize pathogens before they can do any harm. Some examples of barriers include things like skin, stomach acid, tears and vomiting which basically defend the outer parts of your body preventing any types of pathogens from coming in. When skin is exposed…

    Neutrophils are a part of the innate immune system which provides a quick responders to the site of injury and inflammation. When there is an injury to mast cells, they release chemical messengers such as histamine and cytokines. Histamine signals vascular permeability and vasodilation, which allows leakage of blood components intended to fight infection and initiate healing. Cytokines are nonspecific chemical messengers which alert uninjured cells that an injury has occurred. Chemokines are small cytokines which are have the ability to move in a specific direction towards a higher concentration of chemokines, this process is called chemotactic.…

    CD4+ T lymphocytes, or cells, are white blood cells that are involved in immune protection. These cells assist B cells in creating antibodies, allow macrophages to establish heightened antimicrobial activity, recruit neutrophils, eosinophils, and basophils towards inflammation and infection. CD4+ T cells also produce a group of cytokines, which respectively, trigger an abundance of immune responses. T cell differentiation Originally, Mosmann et al., 1986 reported that CD4 T cells can be subdivided into those that produce interferon gamma (IFN-ϒ) and those that produce interleukin 4 (IL-4).…

    However exocytosis is the process in which debris enter a cell; this process can be sectioned off into three different parts: Phagocytosis, pinocytosis and receptor-mediated endocytosis. Phagocytosis is where recognition receptors detect threats to the immune system, and then the macrophage submerges the particle in a pocket called a phagosome where the enzymes are then released into the pocket by one of the organelles (Mosser, D. and Edwards, J. 2008) where lysosomes release digestive enzymes into, breaking down the debris which is then excreted from the cell. Pinocytosis is virtually the same process as phagocytosis except for the cell engulfs liquid in a somewhat smaller sack that is formed during phagocytosis; finally receptor-mediated endocytosis, unlike the other two processes is a selective process; this consists of cell proteins in pits on the surface of the cell acting as receptors which bind with molecules and the cell will only absorb certain cells if they are bound to a particular receptor.…

    COMPONENTS OF EARLY AND LATE IMMUNE RESPONSE IN INFECTIONS Early immune response refers to innate immunity, which is the first line of defense. Innate immunity is a non specific defense mechanism that comes into play immediately or within hours of an antigen’s appearance in the body. These mechanisms include physical barriers for example skin, chemicals in the blood and immune system cells that fight off foreign cells in the body. The innate immune response is activated by chemical properties of the antigen. Late immune response refers to adaptive immunity, which is an antigen specific immune response.…

It is stated that the antibiotic resistance and overuse of vaccine has contributed to the increased incidence of emerging diseases and resistance to their controls and treatments. The human immune system is the protection of the body against potentially damaging foreign bodies and other disease. Pathogens are organisms, including a bacterium, a virus or a fungus and these causes diseases in other organisms. Functions of the immune system and the use of vaccines, antibiotics and the effects of resistance to antibiotics in medicine and agriculture are also discussed.…
