    Insights

    Persistent activation of Gαi/o-coupled receptors causes adenylyl cyclase (AC) supersensitization, leading to cyclic adenosine monophosphate (c AMP) accumulation. This cellular response is linked to drug dependence and central nervous system disorders.

    Area of Science:

    • Neuropharmacology
    • Cellular Signaling
    • Molecular Biology

    Background:

    • Gαi/o-coupled receptors play a crucial role in cellular communication.
    • Persistent receptor activation can lead to adaptive cellular changes.
    • Adenylyl cyclase (AC) activity and cyclic adenosine monophosphate (c AMP) levels are key indicators of cellular response.

    Purpose of the Study:

    • To provide a comprehensive overview of Gαi/o-coupled receptor-mediated AC supersensitization.
    • To discuss the historical context and current understanding of this phenomenon.
    • To explore the implications of AC supersensitization in CNS disorders and drug dependence.

    Main Methods:

    • Literature review of studies on Gαi/o-coupled receptors and AC activity.
    • Analysis of cellular mechanisms underlying AC supersensitization.
    • Discussion of evidence linking AC supersensitization to neurological conditions.

    Main Results:

    • Persistent activation of Gαi/o-coupled receptors leads to enhanced AC activity and c AMP accumulation.
    • AC supersensitization is a significant cellular adaptive response.
    • This phenomenon is implicated in the development of drug dependence and CNS disorders like schizophrenia and depression.

    Conclusions:

    • AC supersensitization is a critical cellular mechanism with broad implications.
    • Understanding AC supersensitization is vital for developing treatments for CNS disorders.
    • Further research is needed to fully elucidate the complexities and therapeutic potential of targeting this pathway.

    G-protein Coupled Receptors

    G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

    Receptor-mediated Endocytosis

    Receptor-mediated endocytosis is when bulk amounts of specific molecules are imported into a cell after binding to cell surface receptors. The molecules bound to these receptors are taken into the cell through inward folding of the cell surface membrane, which is eventually pinched off into a vesicle within the cell. Structural proteins, such as clathrin, coat the budding vesicle.

    G 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...

    Transducer Mechanism: G Protein–Coupled Receptors

    G Protein–Coupled Receptors (GPCRs) are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to various stimuli. GPCRs regulate critical physiological pathways and are excellent drug targets for treating diseases such as diabetes, cancer, obesity, depression, or Alzheimer's. Nearly 35% of approved drugs implement their therapeutic effects by selectively interacting with specific GPCRs.
    GPCRs are also called heptahelical,...

    Internal Receptors01:31

    Internal Receptors

    Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.
