The defects in cilia structure contributes to disease pathogenesis in cystic fibrosis, primary ciliary dyskinesia, and chronic obstructive pulmonary diseases. As a result of mutations in the genes responsible from mobile cilia structure, the microtubule structure is disrupted and protrusions and shrinkage occur in the cilium. These deformations cause loss of cilia function and decrease in ciliary beat frequency. This decrease disrupts the mucociliary clearance mechanism, which is called as the clearance mechanism of mucus from foreign microorganisms and bacteria in the airways. The macrophages and neutrophils migrating to the environment cause cytokine storm due to the inability of mucus to be cleared from the epithelial surface and the disease course exacerbates with the activation of inflammatory pathways. In this review, genes that have a function in mobile cilia formation and that show direct or indirect expression changes in cystic fibrosis, primary ciliary dyskinesia, and chronic obstructive pulmonary diseases are summarized. As a result of change in the expression of these genes, cell differentiation on the lung epithelial surface and lung pathophysiology are affected.

Hücre yüzeyinde bulunan siller; kistik fibrozis, primer siliyer diskinezi ve kronik obstrüktif akciğer hastalıklarında yapı ve işlev bozukluğuna uğrayarak hastalık patogenezinde önemli rol oynarlar. Sil oluşumu sırasında özellikle hareketli sil yapısını oluşturan genlerde görülen mutasyonlar sonucu silin mikrotübül yapısı bozulur ve sil yüzeyinde çıkıntılar ile büzülmeler meydana gelir ya da sil yapısı oluşamaz. Silde oluşan bu deformasyonlar sonucunda sil işlevinin kaybı gerçekleşmekte ve siliyer atım frekansında azalma görülmektedir. Bu azalış, mukusun havayollarındaki yabancı mikroorganizmalardan ve bakterilerden temizlenme mekanizması olarak adlandırılan mukosiliyer klirens mekanizmasını bozmaktadır. Mukusun epitel yüzeyden temizlenememesi, fazla üretilmesi ve kalınlaşması sebebiyle ortama göç eden makrofajlar ve nötrofiller sitokin fırtınasına neden olmakta, inflamatuar yolakların aktifleşmesiyle hastalık seyri ağırlaşmaktadır. Bu derlemede kistik fibrozis, primer siliyer diskinezi ve kronik obstrüktif akciğer hastalıklarında hareketli sil oluşumunda görev alan ve doğrudan ya da dolaylı olarak ifade değişimi gösteren genler ve işlevleri özetlenmiştir. İlişkili genlerin ifade değişimleri sonucunda akciğer epitel yüzeyindeki hücreler farklılaşarak akciğer patofizyolojisi etkilenmektedir.

The publication language of Turkish Journal of Pediatric Disease is English.
Manuscripts submitted to the Turkish Journal of Pediatric Disease will go through a double-blind peer-review process. Each submission will be reviewed by at least two external, independent peer reviewers who are experts in the field, in order to ensure an unbiased evaluation process. The editorial board will invite an external and independent editor to manage the evaluation processes of manuscripts submitted by editors or by the editorial board members of the journal. The Editor in Chief is the final authority in the decision-making process for all submissions. Articles accepted for publication in the Turkish Journal of Pediatrics are put in the order of publication taking into account the acceptance dates. If the articles sent to the reviewers for evaluation are assessed as a senior for publication by the reviewers, the section editor and the editor considering all aspects (originality, high scientific quality and citation potential), it receives publication priority in addition to the articles assigned for the next issue.
The aim of the Turkish Journal of Pediatrics is to publish high-quality original research articles that will contribute to the international literature in the field of general pediatric health and diseases and its sub-branches. It also publishes editorial opinions, letters to the editor, reviews, case reports, book reviews, comments on previously published articles, meeting and conference proceedings, announcements, and biography. In addition to the field of child health and diseases, the journal also includes articles prepared in fields such as surgery, dentistry, public health, nutrition and dietetics, social services, human genetics, basic sciences, psychology, psychiatry, educational sciences, sociology and nursing, provided that they are related to this field. can be published.
