Beta3 adrenergic receptors (β3-ARs) are upregulated in hypoxia and may play a role in fetal development and preterm infant diseases. Their activation offers protective effects, but altered expression in preterm infants could contribute to pathologies.
Area of Science:
- Perinatal Medicine
- Molecular Biology
- Developmental Biology
Background:
- Beta3 adrenergic receptors (β3-ARs) exhibit broad tissue expression and diverse functions.
- Emerging research suggests β3-ARs involvement in common preterm infant complications.
- This systematic review investigates the role of β3-ARs in fetal development and neonatal diseases.
Purpose of the Study:
- To systematically review the scientific literature on the association between β3-ARs, fetal development, and diseases in preterm newborns.
Main Methods:
- Searched PubMed/Medline and Cochrane databases for relevant studies.
- Included studies reporting associations between β3-ARs, fetal development, and preterm infant diseases.
- Selected 16 studies from an initial pool of 1596 articles for the review.
Main Results:
- β3-ARs are upregulated in hypoxic conditions across multiple tissues.
- Activation of β3-ARs promotes pro-angiogenic, anti-inflammatory, immunoregulatory, and metabolic adaptation effects.
- These effects are crucial for normal fetal development.
Conclusions:
- Preclinical data indicate a potential role for β3-ARs in the pathogenesis of numerous preterm newborn pathologies.
- Preterm birth disrupts the natural hypoxic fetal environment, exposing infants to relative hyperoxia.
- Altered β3-AR expression and activity due to premature oxygen exposure may impair fetal development and cause organ injury.

Adrenergic Receptors: β Subtype
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.
