Asthma-I: Introduction01:29

Asthma-I: Introduction

3.6K
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...

Asthma: Pathogenesis and Management

1.4K
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-II: Pathophysiology and Classification

4.4K
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:

Blood Studies for Cardiovascular System III: Serum Lipid Profile

642
Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Area of Science:

  • Genomics
  • Immunology
  • Pharmacogenomics

Background:

  • Non-Hispanic Black individuals experience disproportionately high rates of asthma and severe exacerbations.
  • Understanding asthma pathogenesis requires elucidating gene expression patterns linked to disease status.

Purpose of the Study:

  • To characterize whole blood gene expression and molecular pathways associated with asthma progression in non-Hispanic Black individuals.
  • To identify key molecular drivers and potential therapeutic targets for asthma exacerbations.

Main Methods:

  • RNA sequencing of whole blood samples from the Study of Asthma Phenotypes and Pharmacogenomic Interactions by Race-Ethnicity (SAPPHIRE).
  • Transcriptomic signatures were analyzed for asthma establishment and exacerbation states.
  • Probabilistic causal analysis identified key driver genes preceding exacerbations.

Main Results:

  • Controlled asthma showed upregulated genes in IgA production, asthma pathways, and antigen processing.
  • Impending exacerbations correlated with upregulated Fcγ receptor-mediated phagocytosis, TH1/TH2 differentiation, and neutrophil extracellular trap formation.
  • IL6R, NUMB, and EMG1 were identified as key driver genes preceding asthma exacerbations.

Conclusions:

  • Blood gene expression profiling in non-Hispanic Black individuals offers insights into asthma pathogenesis.
  • Identified potential targets and preventive drug candidates for asthma exacerbations.
  • Findings provide a foundation for developing novel treatments for severe asthma.
