IgM antibodies are the first type of antibody produced in response to an infection. It activates the complement system.…
Imagine spending your entire life trapped inside a bubble of antiseptic perfection,with no germs. You would develop a extremely weak immune system when the inevitable exposure to germs occurred you’d become extremely sick.…
Overusing the antigen concentration can shut down your immune system and make your current state worse because of the virus. Your immune system may reject the antigen concentration and that won’t be good at all!…
These antibodies then begin to bind to antigens on the patients own cell surface. Once these are binded they are recognized as intrinsic or extrinsic. During this phase the cells can act as antigen presenting cells. Another form of Type 2 hypersensitivity is called antibody-dependent cell-mediated cytotoxicity. (The reactions ran can take hours to a day.) Type 4 hypersensitivity which is an independent antibody and its reactions take 2 to 3 days. Unlike others, Type 4 hypersensitivity is not antibody mediated but is a type of cell mediated…
Cytokines are extracellular signaling proteins formed by various cells types in the body. Interleukin-6 (IL-6) is a proinflammatory cytokine and lymphokine. IL-6 is produced by almost all different types of lung cells including endothelial cells, airway epithelial cells, fibroblasts, and, most notably, alveolar macrophages. IL-6 is thought to play a role in all types of acute lung inflammation through its stimulatory effects on lymphocytes and the acute phase response. Interleukin-8 (IL-8), a CXC chemokine, is an important neutrophil chemoattractant and activator.…

5) Pathogenesis: LPS (lipopolysaccharide)- the endotoxin stimulates a powerful host immune response. This response causes cytokines to be release that can lead to fevers and other illnesses.…
Type 1 Hypersensitivity is a reaction that involves many parts of the body, for instance, the skin, eyes, nasopharynx, bronchopulmonary tissue, and the gastrointestinal tract. This reaction may cause a range of minor symptoms to fatality. Common manifestations that may possibly occur during Type 1 Hypersensitivity are rhinitis, asthma, atopic eczema, bee-sting reaction, and gastroenteritis. IgE, released from B cells, is an antibody that mediates hypersensitivity and arms mast cells, which exhibit as the principal component cell of this reaction in the body. The exposure of an allergen in an individual causes plasma B cells to produce the antibody IgE which circulates in small amount in the blood. Immunoglobulin E binds to the IgE receptors on mast cells which ultimately produces IgE antigen-binding sites on the surface of the mast cell. After the exposure of the mast cell with crosslinking of IgE-Fc receptors to an antigen, degranulation results and mediators are released causing signs of inflammation (Copstead & Banasik, 2010, pp. 227-228).…
In Good Pasteurs disease the immune system wrongly recognizes these cells as foreign and attacks and destroys them, as it would to an invading pathogen. There is a combination of glomerulonephritis with alveolar hemorrhage and anti-GBM antibodies. Anti-GBM antibodies…
For example, the person’s blood pressure will drop into the danger zone and the victim will eventually slip into unconsciousness because the body becomes very weak and is just unable to fight off the infection. In addition, the body will also go into septic shock from all of the toxins that the bacteria are spreading. Septic shock is an extensive infection from all the bacteria that causes multiple organ failure and an extremely low blood pressure. It usually results from the toxins produced by the Staphylococcus aureus bacteria, which ultimately leads to…
The proteins can be used for treatments for arthritis and cancer and several other conditions that affect the immune system. (pg 67)…
An autoimmune disease occurs when the body produces an abnormal immune response against self antigens. It is caused by failure of the tolerance processes to protect the host from the action of self reactive lymphocytes. An organ-specific autoimmune disease involves gradual damage to cellular structures and is replaced by the compensating connective tissue which depletes the function of the gland/organ. Type 1 diabetes (TD1), is an organ specific autoimmune disease characterize by distraction of the B cells located at the islets of langerham in pancreas resulting in a limited secretion of hormone. T1D sufferer’ s immune cells such as anti body T cell and CD8 killer cells mistakenly attacks the B cell as a foreign invader. This mechanism is a results of a delayed hypersensitive response to excessive immune reaction meditated by antigen-activated T lymphocytes, including CD4+ and CD8+ T cytotoxic cell . Mediated hypersensitivity reactions may induced by either environmental and self-antigens. Inappropriate activation these cell mediated cell can be directed against self antigens or exogenous antigens which may cause chronic inflammation in a the islets of pancreas in type 1 diabetes (Lopez 2009, pp. 43).…
So what happens during the primary immune response is in order for us to be protected from bacteria, viruses, and other foreign substances known as antigens. The bodies immune system needs to have a plan in being able to help identify these antigens the body has developed a response. The first would be the primary response which when the immune system comes into contact with an antigen for the first time. The immune system must recognize it and make an antibody against it and then store it in memory.…
