Cystic Fibrosis: Pathogenesis01:23

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,...

T Cell Types and Functions01:24

T Cell Types and Functions

3.3K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Rheumatic Heart Disease I: Introduction

892
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

2.0K
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Asthma: Pathogenesis and Management01:20

Asthma: Pathogenesis and Management

1.7K
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.

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

14.0K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

Area of Science:

  • Immunology
  • Vascular Biology
  • Connective Tissue Diseases

Background:

  • Systemic sclerosis is a multisystem disorder with significant mortality.
  • Hallmark abnormalities involve the immune system, vasculature, and connective tissue.
  • Disease initiation involves poorly understood events in susceptible individuals.

Purpose of the Study:

  • To elucidate the complex interplay of dysregulated homeostatic mechanisms in systemic sclerosis.
  • To identify key factors contributing to disease progression.
  • To provide a foundation for improved therapeutic strategies.

Main Methods:

  • This study is a review and synthesis of current knowledge on systemic sclerosis pathophysiology.
  • Analysis of the roles of immune tolerance, endothelial physiology, and extracellular matrix turnover.
  • Examination of the non-sequential, simultaneous nature of regulatory dysfunction.

Main Results:

  • Systemic sclerosis pathogenesis requires simultaneous dysfunction in immune tolerance, endothelial physiology, and extracellular matrix turnover.
  • Disease progression is not linear but depends on the interplay of these factors.
  • Current understanding of initiating events remains limited.

Conclusions:

  • A deeper understanding of the interaction between immune, vascular, and connective tissue regulatory mechanisms is crucial.
  • Targeting these interconnected dysfunctions holds promise for advancing systemic sclerosis treatment.
  • Further research into initiating events is warranted.
