Pulmonary Hypertension: Classification and Pathogenesis

646
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Asthma: Pathogenesis and Management

1.3K
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.

Cystic Fibrosis: Pathogenesis

871
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,...

COPD: Pathogenesis and Clinical Features

1.8K
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...

Internal Receptors01:31

Internal Receptors

74.7K
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

Summary

Purinergic receptors P2X4, P2X7, and P2Y12 play key roles in multiple sclerosis (MS) by influencing immune cells and brain cells. Targeting these receptors may offer new therapeutic strategies for MS.

Area of Science:

  • Neuroimmunology
  • Cellular and Molecular Neuroscience

Background:

  • Multiple sclerosis (MS) is a chronic central nervous system inflammatory disease.
  • Immune cell infiltration and demyelination characterize MS pathology.
  • Purinergic receptors regulate immune and neural cell functions.

Purpose of the Study:

  • To review the role of specific purinergic receptors in MS.
  • To explore P2X4, P2X7, and P2Y12 receptors as potential MS biomarkers.
  • To discuss these receptors as therapeutic targets for MS.

Main Methods:

  • Literature review of experimental autoimmune encephalomyelitis (EAE) models.
  • Analysis of purinergic receptor expression and function in MS.
  • Examination of therapeutic interventions targeting purinergic receptors.

Main Results:

  • P2X4, P2X7, and P2Y12 receptors show altered expression in MS.
  • Activation or blockade of these receptors impacts EAE progression.
  • These receptors influence astrocyte and microglia activity.

Conclusions:

  • P2X4, P2X7, and P2Y12 receptors are critically involved in MS pathogenesis.
  • Emerging evidence supports their potential as MS biomarkers.
  • Targeting these purinergic receptors presents a promising therapeutic avenue for MS.
