Abstract

The airway epithelium is a complex physicochemical barrier to inhaled irritants, allergens, pathogens and noxious substances. It is now clear that bronchial epithelium, in addition to acting as a barrier, plays a crucial role in initiating and augmenting pulmonary tissue defence by contributing various epithelial repair mechanisms. The pulmonary repair process by the contribution of epithelial cell functional transition is tried to be explained by epithelial-mesenchymal transition hypothesis. It is widely accepted that the relation of the epithelium with other submucosal cells such as dendritic cells, smooth muscle cells and fibroblasts has a sentinal role in the initiation and development of various pulmonary diseases. The recent evidence shows that some different repair mechanisms or altered repair process might play role in pathogenesis of pulmonary diseases including acute respiratory distress syndrome, asthma, cystic fibrosis, chronic obstructive pulmonary disease, and idiopathic pulmonary fibrosis. The purpose of this review is to revise the literature about the role of tissue repair mechanisms in the pathogenesis of various pulmonary diseases.

Özet

Hava yolu epiteli inhale irritanlar, allerjenler, patojenler ve zararlı maddelere karşı kompleks bir fizikokimyasal bariyerdir. Bronşiyal epitel, bariyer olarak görev yapmasına ek olarak, çeşitli epitel tamir mekanizmalarını gerçekleştirerek pulmoner doku savunmasını başlatmada ve artırmada önemli bir rol oynar. Epitel hücresindeki fonksiyonel değişimle başlayan akciğer doku tamir süreci epitel-mezenkimal dönüşüm hipoteziyle açıklanmaya çalışılmaktadır. Epitelin dendritik hücre, düz kas hücreleri ve fibroblastlar gibi diğer submukozal hücrelerle ilişkilerinin, çeşitli pulmoner hastalıkların başlamasında ve gelişmesinde koruyucu rol oynadığı yaygın olarak kabul edilmektedir. Yeni kanıtlar, bazı farklı tamir mekanizmalarının veya bozulmuş tamir sürecinin akut solunum sıkıntısı sendromu, astım, kistik fibrozis, kronik obstrüktif akciğer hastalığı ve idiyopatik pulmoner fibrozis gibi pulmoner hastalıkların patogenezinde rol oynayabileceğini göstermektedir. Bu derlemede, farklı pulmoner hastalıkların patogenezinde doku tamir mekanizmalarının rolüyle ilgili literatürün gözden geçirilmesi amaçlanmıştır.
