WebOverall, we only find mild, but not striking, difference in the ion channel toxicity between PtNP-5 and PtNP-70. Upon the mechanisms underlying the acute toxic effects of PtNPs on cardiac electrophysiology, we noticed that the toxic effects appeared rapidly (within 5 mins) either at the cellular AP level (shown in Figure 2 ) or at the ion channel level (see … Web22 jan. 2024 · Recent work has shown that voltage-gated sodium ion channels expressed on peripheral nerve axons, especially NaV1.7, NaV1.8 and NaV1.9 to be critical in pain signaling and transmission. Certain peptides, such as the tarantula-based toxin ProTx-II, are known to block specific sodium channels, preventing nerve cells from transmitting …
WebSpider venoms are a complex mixture of peptides with a large number of neurotoxins targeting ion channels. Although thousands of peptide toxins have been identified from venoms of numerous species of spiders, many unknown species urgently need to be investigated.
