Allergic Reactions and Autoimmunity - When Immune System Functions Go Wild

Allergic Reactions

For daily life, of course we need our immune system. Without having immune system, we could not survive long, but there are times when the immune system may harm us rather than helps us. If you suffer from sneezing and stuffy nose, watery eyes, every spring or fall, your doctor may assured you your hay fever. These symptoms are allergic reaction to pollen, dust and spores in the air. The diseases may also have flare-ups, when they get worse, and remissions, when they all but disappear. When that allergen enters your body, your immune system reacts and attacks foreign objects. The result is itching and swelling of tissues in the rainy nose and eyes. Another example of the immune system works against you is a reaction to poison ivy. The plant releases oil that treated by our immune systems reactively. When the oil touches the skin, you will have a local reaction that leads to itching and a red rash. Again, this reaction is the normal reaction of your immune.

Autoimmunity

The cases of the preceding paragraph is annoying, but rarely life threatening. There are different conditions where the immune system creates more serious problems. One of the tremendous and amazing things about the immune system is, the body immune system differentiate between our normal own cells and tissues us and those unknown (foreign objects). The power of our body immune system to attack foreign objects, but not ours, is a characteristic known as suppression. The body represses the immune response against the same attacks but other things, including bacteria, viruses and cancer cells. Sometimes, the immune system starts attacking our own tissues and those tissues not recognize. Children with juvenile diabetes have a hereditary condition where the immune system kill cells in the pancreas that produce insulin. Insulin is a hormone necessary for balancing the level of sugar in the blood. In the condition where the insulin level dropped, diabetic’s person can not properly use sugar and therefore can become very ill or even die if the blood glucose levels going to roof.

However, autoimmunity can be the cause of a extensive spectrum of human diseases, known as autoimmune diseases. Autoimmune diseases can affect any part of the body, and thus symptoms diverge widely and diagnosis and treatment are often unmanageable.
When the cells that insulin producing have been attacked and destroyed by the immune system (most of the time around the age of five or six years), the diabetic person must take insulin injection on regular basis to normalize the level of blood sugar. There is a time when, the need for a diabetic person to take insulin injections several times a day, but he/she must be careful enough not to inject too much insulin, it can caused fatality. Diabetes type 1 or also called Juvenile Diabetes is the condition of insulin dependent diabetes, known as an autoimmune disease because the immune system suppress and attacks of their own cell body. Other instances of autoimmune disorder are rheumatoid arthritis, a condition where the immune system attacks soft tissue around the area of the joints.

Lupus disease is a disorder condition which the immune system attacks connective tissue around skin area. The autoimmune basis of systemic lupus erythematosus is well accepted since of the availableness of several genetically determined, while not simulating lupus as seen in the clinic, do very nearly replicate the serological characteristics and some pathological features.”

What can we find out from these two very dissimilar problems with the immune system to learn? First, our immune system can be in under functions critical or damage by a virus. Second, we have the conditions in which the immune system aggresses our own bodies, makes us sick, and can cause death. This information and fact shows that the immune system can operates those who believe that the vast majority has been developed to keep a very fine and works perfectly. Immune system is complex body protection, which is essential to our survival. Your journey for understanding the immune system is only beginning. As we explore, further scientists consider will see why many are extremely complex and surprising system body. It is a world from different tissues and cells, and proteins the complex choreography of dance, see the immune system.
