GsMTx4 had been used for years to investigate the functional role of cat …The GsMTx-4 peptide isolated from tarantula venom is a specific modifier of nonselective mechanosensitive channels . Its inhibitory action is within the outer membrane leaflet and is considered to be through altering the distortion of the boundary lipids adjacent to the channel that occurs during membrane stretch ( 16 , 17 ).GsMTx-4 was also found to inhibit both TRPC1 and TRPC6 channels 5,6, as well as Piezo1, the mechanosensitive channel 7. Antimicrobial activity is shown against several Gram-positive and Gram-negative bacteria as well 8 .

Pharmacological inhibition of Piezo1 (GsMTx-4) attenuated plaque formation, decreased the level of inflammation related factors (JNK, TNF-α, NF-κB, VCAM-1) of carotid plaque in atherosclerotic mice. Meanwhile, ox-LDL also upregulates Piezo1 and inflammation proteins (NF-κB, JNK and TNF-α) in endothelium cells (ECs).

GsMTx4 is a spider venom peptide that selectively inhibits cationic mechanosensitive channels (MSCs) such as TRPC1 and TRPC6 and Piezo channels. GsMTx4 blocks stretch-activated cation channels in astrocytes, cardiac cells, and smooth and skeletal muscle cells. GsMTx4 also inhibits TACAN, a mechanosensitive ion channel involved in the pain response.

GsMTx-4 accelerates the desensitization of muscle-type nAChRs in C2C12 myotubes Previously, 1 μM GsMTx-4 was used to block the mechanosensitivity of muscle-type nAChRs [25]. During the experiment, toxic inhibition of the nAChR single channel was observed. To determine the properties of GsMTx-4-mediated inhibition,GsMTx-IV failed to inhibit 100% of current from any Na V channel subtype, and SgTx-I caused a delay in channel inactivation accompanied by an increase in sodium peak current. Despite these differences between GsMTx-IV and SgTx-I compared with the remaining seven GMTs, both GsMTx-IV and SgTx-I were not selective (Fig. 8 and Table 1).Manipulation of the pancreas during surgery can induce acute pancreatitis due to zymogen activation.

This finding ...Biochem/physiol Actions. GsMTx4 (Grammostola Mechanotoxin #4) is a tarantula venom-derived 34-mer amphipathic cysteine knot peptide that exerts its cationic mechanosensitive channels (MSCs; stretch-gated ion channels or SACs) modulatory activity by changing local membrane properties near the channels.To characterize the current-voltage relation, we applied ramped pulses from –100 to +100 mV at 5-second intervals. The flow-induced current was markedly inhibited in the presence of GsMTx-4 (Figure 4, I and J), indicating that Piezo1 mediates cellular current in C2C12 myotubes in response to mechanical stimulation.GsMTx-4 caused a significant reduction in ZAP70 phosphorylation for Jurkat cells treated with FSS and antibodies in comparison to Jurkat cells treated with FSS, antibodies, and no GsMTx-4 (Fig. 4C). This indicates that FSS enhances T cell activation by inducing the activation of mechanosensitive ion channels that result in calcium influx.property of GsMTx-4 may lead to a better understanding of the desensitization of ligand-gated channels and disease therapy.
