Neurotrophins: Expression of Brain-Lung Axis Development

Area of Science:

• Neuroscience
• Developmental Biology
• Pulmonology

Background:

• Neurotrophins (NTs) are soluble growth factors essential for neuronal survival during development.
• Emerging data link altered NTs levels and function to neurological and pulmonary diseases.
• NTs are implicated in neurodevelopmental disorders ('synaptopathies') and various airway and lung conditions.

Purpose of the Study:

• To comprehensively review the role of NTs in brain and lung development.
• To explore the physiological and pathophysiological significance of NTs.
• To highlight NTs' involvement in both central and peripheral systems.

Main Methods:

• Literature review of existing studies on neurotrophins.
• Analysis of clinical data on NTs in disease.
• Synthesis of information on NTs' presence in various tissues.

Main Results:

• NTs are critical for neuronal survival and synaptic plasticity.
• Altered NTs expression is associated with neurodevelopmental disorders.
• NTs play significant roles in the pathophysiology of airway diseases, neonatal lung diseases, fibrosis, and lung cancer.

Conclusions:

• NTs are key physiological and pathophysiological players in brain and lung development.
• Dysregulation of NTs contributes to severe neurological and pulmonary conditions.
• Further research into NTs' roles may offer therapeutic insights.
