Disorders of Immune System

The immune system is essential for our survival. However, some situations may arise where this system does not function well. Immune system disorders may be the starting point of many diseases. Sometimes, the immune system is too weak and unable to efficiently fight infections: the immune system is too aggressive and attack harmless elements of the environment: this is the case of allergies.

• Allergies:

When you immune fail to tolerate some malfunctions this results in immune disorders or diseases. One of these most familiar disorders is allergy. Some allergies such as hay fever and hives might be attributed to antibody called ‘IgE;. Whenever any person is going to be affected with allergy such as grass pollen allergy or other allergy, the B cells will be forming the ‘IgE’ adding to it the grass pollen. These ‘IgE’ molecules will be connected to granule-containing cells which are called as mast cells, which are found in large amount in the lungs, skin, tongue and other internal linings of the body. The second time the person is in contact with the grass pollen, these ‘IgE’ that are engaged with the mast cells will produce powerful chemical that will cause the person to the initiation of what is known as allergy symptoms that some are wheezing , sneezing and other symptoms to occur(National Cancer Institute, 2009).
