Asthma-II: Pathophysiology and Classification01:26

Asthma-II: Pathophysiology and Classification

2.6K
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

293
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.

Esophageal Strictures-I: Introduction01:30

Esophageal Strictures-I: Introduction

44
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

2.2K
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Asthma-I: Introduction01:29

Asthma-I: Introduction

2.6K
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...

Gastroesophageal Reflux Disease I: Meaning and Pathophysiology01:29

Gastroesophageal Reflux Disease I: Meaning and Pathophysiology

261
Gastroesophageal Reflux Disease (GERD) involves the recurrent backflow of the stomach or duodenal contents into the esophagus, leading to troublesome symptoms and potential esophageal mucosal damage. Although GERD is often referred to as a disease, it is more accurately described as a syndrome, as it encompasses a range of symptoms and complications rather than a singular pathological entity, impacting a large number of individuals as the most prevalent upper gastrointestinal problem. Roughly...

Area of Science:

  • Immunology
  • Gastroenterology
  • Dermatology

Background:

  • Eosinophilic esophagitis (EoE) and atopic dermatitis (AD) are type 2 helper cell-mediated diseases.
  • These conditions share immunological pathways, genetic risks, and clinical features with other atopic diseases like asthma and allergies.
  • Both EoE and AD involve impaired immune responses leading to CD4+ Th2 differentiation and elevated immunoglobulin E (IgE).

Purpose of the Study:

  • To review the clinical and immunological connections between EoE and AD.
  • To explore the implications of their co-occurrence for research and treatment.
  • To highlight shared characteristics along the skin-gut axis.

Main Methods:

  • This is a narrative review.
  • Literature search on EoE, AD, and related atopic conditions.
  • Analysis of shared clinical, immunological, and genetic factors.

Main Results:

  • EoE and AD exhibit overlapping features, immune responses, and genetic predispositions.
  • Both diseases affect stratified squamous epithelium and share treatment strategies.
  • The co-occurrence of EoE and AD is an area of growing research interest.

Conclusions:

  • EoE and AD share significant clinical and immunological similarities, suggesting a common underlying pathophysiology.
  • Understanding these connections can inform novel therapeutic strategies and research directions.
  • Targeting shared pathways may offer improved management for patients with comorbid EoE and AD.
