GsMTx4 (TFA)

• Description:

  GsMTx4 TFA is a spider venom peptide that selectively inhibits cationic-permeable mechanosensitive channels (MSCs) belonging to the Piezo and TRP channel families. GsMTx4 TFA also blocks cation-selective stretch-activated channels (SACs), attenuates lysophosphatidylcholine (LPC) -induced astrocyte toxicity and microglial reactivity. GsMTx4 TFA is an important pharmacological tool for identifying the role of these excitatory MSCs in normal physiology and pathology[1][2][4].
