Eosinophils are white blood cells that are involved in the immune response of the body against parasites. Asthma is a disease in which eosinophils are present in increased amounts in the airways of the lungs. These cells cause swelling and narrowing of the bronchial tubes in the lungs. There are two main types of asthma, namely, type I and type II. A person who has type I asthma is allergic to certain substances. These substances trigger the eosinophils in the blood to release substances that damage the tissues in the Eotaxin-2 airways. In the case of a person who has type II asthma, allergies do not play a role. He or she usually has more severe symptoms. Asthma symptoms include chest tightness, wheezing, coughing, shortness of breath, and difficulty breathing.
A study that looked at the levels of Eotaxin in the blood of asthmatic patients showed that levels were elevated in the patients’ blood. Levels increased along with the worsening of the condition. An experimental drug named EnzyChrom was found to significantly decrease the amount of Eotaxin in the blood.
