Steps To Take To Prevent Your Nasal Allergy?

Do you know why and how your nose could feel itching and sensitive? The substance that causes itching and sensitive of your nose is called allergen. These include pollen, mold, dust mites, certain foods, latex, animal dander, and others.

These allergens sensitize the nasal mucosal membrane through a sensitization process, which typically involves a few types of cell in our body, such as macrophage, lymphocyte and mast cell. In the beginning of the sensitization, allergens penetrate through the mucosal surface in our nasal passage. The easiness of the allergens penetrate through the mucosal surface is due to the deficiency of IgA antibodies, which main function is eliminating micro organisms that adhere to the mucosal surface.

Usually, patients, who allergic to the allergen, have lower level of IgA antibodies. Do you know why and how your nose could feel itching and sensitive?

These allergens sensitize the nasal mucosal membrane through a sensitization process, which typically involves a few types of cell in our body, such as macrophage, lymphocyte and mast cell. In the beginning of the sensitization, allergens penetrate through the mucosal surface in our nasal passage. The easiness of the allergens penetrate through the mucosal surface is due to the deficiency of IgA antibodies, which main function is eliminating micro organisms that adhere to the mucosal surface.

Usually, patients, who allergic to the allergen, have lower level of IgA antibodies. The second step of the sensitization process is scavenging of the allergen by the macrophage cell. Macrophage cell is the large scavenger cell in the blood, whose function is eating up antigen, which is from outside of our body. During the scavenging process, macrophage cells also pass information about the invasion of foreign antigen to the lymphocyte cell, which involves several enzymes.

Lymphocytes are stimulated by this information and multiplied to transform into plasma cells, which would synthesize IgE antibodies. IgE antibodies move to the mast and basophil cells around the eye, mouth and nose via tissue fluid and blood where they bind to the mast and basophil cells. When an allergen forms a bridge between two IgE molecules on the mast or basophil cells surface, histamine, which is a primary chemical mediator, will be released. This chemical will stimulate exocrine glands, contract smooth muscles in the bronchi, dilate blood vessels and increase their permeability and cause itch. Second chemical; prostaglandin, which is a secondary mediator, is synthesized in all types of cell and this chemical will cause inflammation around the mucosal surface inside the nostril.
