The „changes” occurring in the expression of the factors involved in the apoptotic chain at the level of the respiratory epithelium in asthma is still an unsolved issue. At this level an important role is played by the mitochondria and the factors that influence the membrane permeability, especially the Bcl-2 super family. The purpose of this study is to evaluate both the changes in the expression of the Bcl-2 and of the Bax proapoptotic factors at the respiratory epithelium level in 21 patients with bronchial asthma of different degrees of severity of disease (aaccording to GINA - Global Initiative For Asthma). To accomplish this, fragments of the bronchial mucosa were obtained through fiberbronchoscopy, being afterwords hystologically prepare in view of the immunomarking with anti Bcl-2 and anti-Bax antibodies. Microscopic examination revealed an important decrease in the level of proapoptotic factor Bcl-2 in patients with persistent severe forms of the disease and a significant decrease in the expression of the proapototic Bax factor at the respiratory epithelium level even in the early stages of the disease. Knowing all the factors involved in apoptosis at the respiratory epithelium level in bronchial asthma, as well as of their expression changes will be at the core of new therapeutical approaches to of this disease.
