AI Article Synopsis

  • The study by Collaço et al. explores the inhibitory effects of ω-grammotoxin-SIA on various voltage-gated ion channels.
  • In addition to its known impact on calcium (Ca2+) and potassium (K+) channels, the toxin also inhibits voltaged-gated sodium (Na+) channel currents.
  • These findings suggest that ω-grammotoxin-SIA has a broader effect on ion channel activity than previously understood, which could have implications for understanding its biological roles.

Article Abstract

This JGP study (Collaço et al. https://doi.org/10.1085/jgp.202413563) reveals that in addition to voltage-gated Ca2+ and K+ channels, ω-grammotoxin-SIA also inhibits voltage-gated Na+ channel currents.

The high potassium-induced potentiation of spontaneous glycine release in extracellular Ca2+-free conditions was studied in mechanically dissociated rat spinal dorsal horn neurons using whole-cell patch-clamp technique. Elevating extracellular K+ concentration reversibly increased the frequency of spontaneous glycinergic inhibitory postsynaptic currents (IPSCs) in the absence of extracellular Ca2+. Blocking voltage-dependent Na+ channels (tetrodotoxin) and Ca2+ channels (nifedipine and omega-grammotoxin-SIA) had no effect on this potassium-induced potentiation of glycine-release.

Ca2+ influx in resting rat sensory neurones that regulates and is regulated by ryanodine-sensitive Ca2+ stores.

1. Store-operated, voltage-independent Ca2+ channels are activated by depletion of intracellular Ca2+ stores and mediate Ca2+ influx into non-excitable cells at resting membrane potential. We used microfluorimetry, patch-clamp and Mn2+-quench techniques to explore the possibility that a similar mechanism exists in rat dorsal root ganglion (DRG) neurones in primary culture.

Mechanically activated currents in chick heart cells.

J Membr Biol

December 1996

Biophysical Sciences, 120 Cary Hall, SUNY at Buffalo, Buffalo, NY 14214, USA.

As predicted from stretch-induced changes of rate and rhythm in the heart, acutely isolated embryonic chick heart cells exhibit whole-cell mechanosensitive currents. These currents were evoked by pressing on cells with a fire polished micropipette and measured through a perforated patch using a second pipette. The currents were carried by Na+ and K+ but not Cl-, and were independent of external Ca2+.
