D-GsMTx4 TFA, a selective spider venom peptide, is a TRPC1 6 and Piezo2 inhibitor that inhibits cation-permeable mechanosensitive channels (MSCs) belonging to the Piezo and TRP channel families, blocks cation-selective stretch-activated channels (SACs), and attenuates lysophosphatidylcholine (LPC)-induced astrocyte toxicity and microglia reactivity. toxicity and microglia reactivity.D-GsMTx4 TFA prevented myocardial infarction in a mouse model of ischemia reperfusion and can be used to characterize the role of excitatory MSCs in normal physiology and pathology.

Phoenixin-14 (PNX-14), an active endogenous isoform, induces an anxiolytic effect by activating the AHA GnRH system in mice and protects against ischemia reperfusion-induced cytotoxicity in microglia [1] [2].

PapRIV, a quorum-sensing heptapeptide derived from B. cereus, undergoes synthesis as a 48-amino acid polypeptide. This compound is secreted and then extracellularly processed by NprB proteases into its active form. At concentrations ranging from 1-25 µM, PapRIV triggers the production of IL-6 and TNF-α, as well as NF-κB translocation, specifically in BV-2 microglia cells.
