What is a system that fights disease and controls the immune response?
Which is a renal disease in which substances from the immune response to the streptococcus bacterium collect in the capillary network of the nephron?
What is the name for the immune system response to an infection by a pathogen against which individual has been vaccinated?
All vaccinations work on the same principle. By injecting into the body a material which is chemically similar to a given disease organism (such as the tuberculosis baccilus) the immune system is activated, and will prepare an immune response to that disease before the actual disease organism ever enters the body. Therefore there is a faster and more effective immune response if the disease is ever actually encountered.
Rheumatic Arthritis is an auto-immune disease. These diseases are caused when the immune system of the body triggers an immune response against its own cells and tissues, thereby degrading and harming the body. In other words, the immune system fails to identify the body constituents as 'self', and rather identifies them as 'foreign'; triggering an immune response against them and attacking them. Other examples are - Lupus, Crohn's disease, Grave's disease, etc.
There are many different diseases which result from problems with the immune system; broadly speaking, there are two types, which involve either an excessive immune response, causing an autoimmune disease such as multiple sclerosis, or an insufficient immune response, causing a disease such as AIDS. There are also many different reasons why the immune system may not work correctly. However, the greatest single threat to the functioning of the immune system is the human immunodeficiency…
Why does a person with a disease such as AIDS have a hard time trying to fight off a simple disease such as a cold or a flu?
Experts are not sure, and studies and research are ongoing. Several theories exist but unfortunately, none of these theories has yet been scientifically proven. Most experts agree that the immune system of people with Crohn's disease reacts abnormally - it treats good bacteria, foods, and other substances that are good for us as foreign and unwanted substances. In other words, the patients own immune system attacks. This leaves us with the question, does Crohn's disease…
