Summary
Epigenetic mechanisms, including DNA methylation and microRNA changes, are key in immune-mediated lung diseases. Understanding these epigenetic marks offers new biomarkers and therapeutic targets for conditions like asthma and fibrosis.
Area of Science:
- Pulmonary Medicine
- Immunology
- Epigenetics
Background:
- Immune-mediated pulmonary diseases stem from immune imbalance, causing inflammation, tissue damage, and lung function loss.
- Epigenetic mechanisms are increasingly recognized for their role in inflammation, autoimmunity, and cancer.
- Recent research highlights epigenetic regulation in immune-mediated lung diseases, influencing disease development and progression.
Purpose of the Study:
- To review the latest experimental and translational epigenetic studies in immune-mediated pulmonary diseases.
- To explore how epigenetic changes regulate molecular pathways in these conditions.
- To discuss the potential of epigenetic marks as biomarkers and therapeutic targets.
Main Methods:
- Literature review of experimental and translational epigenetic studies.
- Analysis of epigenetic mechanisms such as DNA methylation, histone modifications, and microRNA expression.
- Examination of the role of epigenetics in gene transcription and environmental factor interactions.
Main Results:
- Aberrant DNA methylation, histone modifications, and microRNA dysregulation impact gene transcription in immune-mediated lung diseases.
- Epigenetic changes contribute to T cell differentiation, myofibroblast activation, and extracellular matrix accumulation.
- Epigenetics mediates the interplay between environmental and genetic factors in lung disease development.
Conclusions:
- Epigenetic alterations are crucial in the pathogenesis of immune-mediated pulmonary diseases.
- Identifying abnormal epigenetic marks can lead to novel biomarkers for prediction and diagnosis.
- Epigenetics presents promising therapeutic targets for challenging conditions like steroid-resistance and progressive fibrosis.

5.0K
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:

77
Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...

01:20COPD: Pathogenesis and Clinical Features
2.1K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

01:23Chronic Obstructive Pulmonary Disease I: Introduction
71
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...

01:23Chronic Obstructive Pulmonary Disease II: Emphysema
155
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.

01:28Asthma I: Introduction
311
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
