Insights

This review explores the roles of canonical transient receptor potential (TRPC) channels in vascular cells. It examines their functions in platelets, smooth muscle, and endothelial cells using genetic and tissue-based analyses.

Area of Science:

  • Physiology
  • Molecular Biology
  • Vascular Biology

Background:

  • Mammalian transient receptor potential (TRP) channels form a superfamily, with the canonical TRPC family being evolutionarily conserved.
  • TRPC channels (TRPC1-7) are activated by phospholipase C (PLC)-coupled receptors, but their interaction with STIM and ORAi proteins in store-dependent pathways remains debated.
  • TRPC proteins are implicated in various cellular functions within the vascular system.

Purpose of the Study:

  • To review the proposed functions of TRPC proteins in vascular cells, including platelets, smooth muscle cells, and endothelial cells.
  • To present data on the physiological roles of TRPC channels in the vascular system.
  • To discuss controversial aspects of TRPC channel regulation by store-dependent mechanisms.

Main Methods:

  • Literature review of TRPC channel functions in vascular cells.
  • Analysis of physiological functions in isolated tissues with reduced TRPC channel activity.
  • Examination of data from gene-deficient mouse models lacking specific TRPC channels.

Main Results:

  • TRPC channels play significant roles in vascular cell function.
  • Evidence from genetic models and tissue studies elucidates TRPC channel physiology.
  • Controversies regarding STIM/ORAi regulation of TRPC channels persist.

Conclusions:

  • TRPC channels are crucial for vascular system physiology.
  • Further research is needed to fully understand TRPC channel regulation and function in vascular cells.
  • TRPC proteins represent important targets for understanding and potentially treating vascular diseases.

Vascular Spasm01:16

Vascular Spasm

The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last for...
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...
Overview of the Vascular System01:20

Overview of the Vascular System

The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...
Cell Signaling in Plants01:25

Cell Signaling in Plants

Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...
Transducer Mechanism: Enzyme-Linked Receptors01:27

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
Non-Canonical Wnt Signaling Pathways01:41

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...
