Mechanism of Ciliary Motion01:05

Mechanism of Ciliary Motion

4.9K
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

Microtubules in Signaling

The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...

Cystic Fibrosis: Pathogenesis

1.1K
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Chronic Obstructive Pulmonary Disease I: Introduction

33
Chronic obstructive pulmonary disease is a common, preventable, and treatable respiratory disorder characterized by persistent symptoms and progressive airflow limitation. This limitation results from a combination of small-airway disease (obstructive bronchiolitis) and parenchymal destruction (emphysema), both driven by chronic inflammation from exposure to harmful particles or gases.The disease includes two main pathological entities: emphysema, marked by destruction of alveolar walls and...

Chronic Obstructive Pulmonary Disease-I: Introduction

4.0K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Background:

  • Primary ciliary dyskinesia (PCD) is an inherited condition impacting cilia function.
  • It leads to chronic respiratory infections, infertility, and situs abnormalities.
  • Diagnosing PCD is complex, relying on clinical signs, functional tests, and genetic analysis.

Purpose of the Study:

  • To review current diagnostic and therapeutic strategies for PCD.
  • To highlight the role of emerging genetic testing and specialized care centers.

Main Methods:

  • Literature review of PCD diagnosis and management.
  • Discussion of current screening tools (nasal nitric oxide, genetic testing).
  • Overview of treatment modalities and the development of PCD care networks.

Main Results:

  • Diagnosis remains challenging, with 21 known causative genes identified.
  • Comprehensive genetic testing offers potential for early diagnosis in infants.
  • Standardized, multidisciplinary care at specialized centers is crucial for improved outcomes.

Conclusions:

  • Developing a network of specialized PCD clinical centers is essential for coordinated care.
  • Advancements in genetic testing and standardized treatments promise better outcomes for PCD patients.
  • Improved knowledge sharing and collaborative efforts will enhance PCD management globally.
