Adenosine triphosphate (ATP) acts as a cotransmitter alongside classical neurotransmitters in both the peripheral and central nervous systems. This cotransmission allows for nuanced, localized adjustments in neurotransmission and neuromodulation.
Area of Science:
- Neuroscience
- Neurochemistry
Background:
- Adenosine triphosphate (ATP) is recognized as a cotransmitter in various neuronal systems.
- Its release patterns and proportions differ across species, tissues, and physiological states.
Purpose of the Study:
- To elucidate the diverse roles and mechanisms of ATP cotransmission in the nervous system.
- To highlight the significance of cotransmission in modulating neurotransmission.
Main Methods:
- Review of existing literature on ATP cotransmission.
- Analysis of studies detailing ATP release with various classical and non-classical neurotransmitters.
Main Results:
- ATP is released with noradrenaline and neuropeptide Y from sympathetic nerves.
- It cotransmits with acetylcholine in parasympathetic nerves and glutamate in sensory nerves.
- ATP also pairs with dopamine and serotonin in the central nervous system, and nitric oxide in enteric nerves.
Conclusions:
- ATP cotransmission is a widespread phenomenon in both central and peripheral nervous systems.
- The varied combinations of cotransmitters provide fine-tuning of neural signaling.
- Cotransmission mechanisms contribute to subtle, localized variations in neurotransmission and neuromodulation.

Pore Transport and Ion-Pair Transport
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct microscopic...
