Summary
Adenosine triphosphate (ATP) is a key signaling molecule in the nervous system, acting as a neurotransmitter and neuromodulator. Purinergic signaling, mediated by ATP, plays crucial roles in development and disease, with ongoing therapeutic developments.
Area of Science:
- Neuroscience
- Cell Biology
- Pharmacology
Background:
- Adenosine triphosphate (ATP) was identified as a neurotransmitter in 1972.
- ATP functions as a co-transmitter in various neuronal systems and has short-term signaling and long-term trophic roles.
- Purinergic receptors (P1, P2X, P2Y) are diverse and widespread in neuronal and non-neuronal cells.
Purpose of the Study:
- To review the multifaceted roles of purinergic signaling in physiological and pathological processes.
- To highlight the evolutionary origins and broad distribution of purinergic signaling.
- To discuss the therapeutic potential of targeting purinergic pathways for various diseases.
Main Methods:
- Literature review of purinergic signaling research.
- Identification and classification of purinergic receptors.
- Analysis of ATP release and degradation mechanisms.
Main Results:
- ATP is a crucial signaling molecule involved in neurotransmission, neuromodulation, and secretion.

01:11IP3/DAG Signaling Pathway
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and produces two-second...
01:15Amplifying Signals via Second Messengers
Many receptor binding ligands are hydrophilic; they do not cross the cell membrane but bind to cell-surface receptors. Thus, their message must be relayed by second messengers present in the cell cytoplasm. There are several second messenger pathways, each with its own way of relaying information. For example, the G protein-coupled receptors can activate both phosphoinositol and cyclic AMP (cAMP) second messenger pathways. The phosphoinositol pathway is active when the receptor induces...
01:45Endocrine Signaling
Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.
01:15G Protein-coupled Receptors
G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

01:30Parasympathetic Signaling
Parasympathetic signaling plays a crucial role in regulating various physiological processes. It involves the release of acetylcholine (ACh) by parasympathetic neurons, which can have localized and short-lived effects. The majority of ACh released is rapidly inactivated at the synapse by the enzyme acetylcholinesterase (AChE), which hydrolyzes Ach into choline and acetate. Additionally, the tissue cholinesterase deactivates any ACh diffusing into the surrounding tissues.
