The Immunological Process in an Allergic Reaction

immunological allergic reaction
Allergens are the trigger for human body allergic reaction. It is one of human immunological process to react for invader substance. We find most allergens are common in our environment. Most allergic reactions developed over the years by the immune system. If someone who has suffered from allergies for a long time, they mostly will know when their body gives immediate reaction to an allergen. (more…)

Dietary Management of Oral Allergy Syndrome

oral allergy syndrome
Oral allergy syndrome is one form of allergy that body have allergic reaction to fruits and vegetables. Based on statistics facts, The American Academy of Allergy Asthma and Immunology described that probably one third of people allergic to pollen may can extend and develop to oral allergy syndrome. As a matter of fact, not only pollen and fruits allergy are related, but pollen allergy can lead into the oral allergy to certain fruits and vegetables. (more…)

Barrier Cells, Innate Immunity, and Allergic Inflammation

Contact of pathogens with the innate immune system will most frequently occur at epithelia, and the biology of the airway epithelium is of considerable importance in asthma. Airway epithelia express a range of innate immune receptors, allowing them to function as a line of first response to pathogens: their ability to detect and respond to pathogens must clearly be substantial, given that they form the main target for most respiratory viruses.

There are also potentially close relationships between epithelial cells and other cells of the innate immune system such as DCs and macrophages.

Cooperative networks that regulate airway inflammation are discussed in more detail below. Interestingly, defective responses to respiratory viruses are evident in epithelial cells from asthmatics, which may be relevant in the pathology of asthma exacerbations, and phenotypic differences in epithelia between asthmatics and normal subjects have been demonstrated.
