Area of Science:
- Pharmacology and Cell Biology
- Focuses on purinergic signaling and P2 receptors.
Background:
- Purinergic signaling involves extracellular nucleotides acting on P2 receptors.
- P2 receptors are crucial in various physiological and pathological processes.
Purpose of the Study:
- To provide a comprehensive reference on P2 receptor distribution and function across all body systems.
- To detail the historical context, molecular evidence, and functional roles of P2X and P2Y receptors.
Main Methods:
- Literature review synthesizing historical data up to 1994.
- Summary of evidence for P2X and P2Y receptor subtype mRNA and protein expression.
- Inclusion of functional data and discussion of receptor plasticity.
Main Results:
- Comprehensive overview of P2 receptor distribution and function in diverse organs and cells.

Functional Brain Systems: Reticular Formation
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...

Adrenergic Receptors: ɑ Subtype
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase...
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.
