Insights

Canonical transient receptor potential 4 (TRPC4) channels regulate calcium entry and cellular functions. This review covers TRPC4 physiology and the development of small molecule modulators for therapeutic potential.

Area of Science:

  • Molecular Cell Biology
  • Neuroscience
  • Physiology

Background:

  • Canonical transient receptor potential 4 (TRPC4) channels are non-selective cation channels crucial for phospholipase C-dependent calcium (Ca2+) influx.
  • TRPC4 channels are activated by G protein-coupled receptors and receptor tyrosine kinases, and modulated by Gi/o proteins, lipids, and other signaling pathways.
  • These channels play significant roles in regulating the excitability of gastrointestinal smooth muscles and central nervous system neurons.

Purpose of the Study:

  • To provide a comprehensive overview of recent advancements in understanding TRPC4 channel physiology.
  • To highlight the development and potential of small molecular modulators targeting TRPC4 channels.

Main Methods:

  • Literature review of recent research on TRPC4 channel function and pharmacology.
  • Analysis of signaling pathways and regulatory mechanisms involved in TRPC4 channel activity.
  • Survey of identified small molecules and their effects on TRPC4 channel modulation.

Main Results:

  • TRPC4 channels are integral to cellular calcium homeostasis and signaling cascades.
  • Diverse physiological processes, including smooth muscle contraction and neuronal excitability, are influenced by TRPC4 activity.
  • Emerging small molecules demonstrate potential for modulating TRPC4 channel function, offering therapeutic avenues.

Conclusions:

  • Continued research into TRPC4 channel physiology is essential for understanding its broad physiological roles.
  • The development of specific TRPC4 modulators represents a promising strategy for treating conditions associated with channel dysfunction.
  • Further investigation into TRPC4 channel pharmacology could lead to novel therapeutic interventions.

Thermosensation01:43

Thermosensation

Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

GPCRs Regulate Adenylyl Cylase Activity01:09

GPCRs Regulate Adenylyl Cylase Activity

Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of...

Transducer Mechanism: G Protein–Coupled Receptors01:30

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,...

G-Protein Gated Ion Channels01:21

G-Protein Gated Ion Channels

GPCRs are primarily responsible for our sense of smell, taste, and vision.  The binding of a sensory stimulus activates GPCR to stimulate effector proteins, many of which are ion channels in the sensory organs. GPCRs modulate the opening and closing of the target ion channels either directly by binding them, or by releasing second messengers that activate these channels. As ions move across the membrane, the membrane potential is altered, which induces an appropriate response.

Mechanically-gated Ion Channels01:12

Mechanically-gated Ion Channels

Mechanically-gated ion channels are proteins found in eukaryotic and prokaryotic cell membranes that open in response to mechanical stress. Tension, compression, swelling, and shear stress can alter the conformation of the protein, opening a transmembrane channel that allows the passage of ions for signal transmission. In eukaryotes, mechanically-gated channels are distributed in several regions like the neurons, lungs, skin, bladder, and heart, where they play critical roles in numerous...

Non-gated Ion Channels01:24

Non-gated Ion Channels

Ion channels are specialized proteins on the plasma membrane that allow charged ions to pass down their electrochemical gradient. Their main function is to maintain the membrane potential which is critical for cell viability. These channels are either gated or non-gated and can transport more than a thousand ions within milliseconds for the cellular event to occur.
Compared to the gated ion channels, the non-gated channels, also known as leakage or passive channels, have no gating mechanism....
