Asthma-II: Pathophysiology and Classification

3.0K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Asthma: Pathogenesis and Management

772
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Asthma-I: Introduction

2.8K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Role of ER in the Secretory Pathway

5.7K
Eukaryotic cells have a special pathway that enables communication between various intracellular membrane-bound compartments and also with the extracellular environment. This pathway is termed as the secretory pathway.
Components of the secretory pathway
About a third of proteins synthesized in the cell are sorted via the secretory route. They shuffle between different compartments in membrane-bound vesicles until they reach their final destination. The main intracellular compartments involved...

Chronic Obstructive Pulmonary Disease-II: Pathophysiology

3.2K
Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

Breathing01:05

Breathing

60.5K
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Area of Science:

  • Pulmonary Medicine
  • Immunology
  • Cell Biology

Background:

  • Airway hyperresponsiveness (AHR) is a critical factor in lung diseases like asthma and COPD.
  • AHR increases perioperative risks and mortality, linked to inflammation, remodeling, and mucus secretion.
  • Endoplasmic reticulum stress is implicated in the development of these airway pathologies.

Purpose of the Study:

  • To review the role of endoplasmic reticulum stress in immune cells and airway cells contributing to AHR.
  • To elucidate mechanisms of endoplasmic reticulum stress in airway hyperresponsiveness.
  • To identify novel strategies for preventing perioperative airway complications related to AHR.

Main Methods:

  • Literature review focusing on endoplasmic reticulum stress.
  • Analysis of its effects on epithelial cells, dendritic cells, eosinophils, and neutrophils.
  • Examination of its impact on airway smooth muscle and epithelial cell differentiation and remodeling.

Main Results:

  • Endoplasmic reticulum stress influences immune cell function in airway inflammation and mucus secretion.
  • It plays a role in the differentiation and remodeling of airway smooth muscle and epithelial cells.
  • These processes are key mechanisms underlying airway hyperresponsiveness.

Conclusions:

  • Endoplasmic reticulum stress is a significant contributor to airway hyperresponsiveness.
  • Targeting endoplasmic reticulum stress pathways may offer new therapeutic avenues for AHR.
  • Further research can inform perioperative management strategies to mitigate AHR risks.
