Manipulation of a spider peptide toxin alters its affinity for lipid bilayers and potency and selectivity for voltage-gated sodium channel subtype 1.7

Journal of Biological Chemistry, 2020
Huwentoxin-IV (HwTx-IV) is a gating modifier peptide toxin from spiders that has weak affinity for the lipid bilayer. As some gating modifier toxins have affinity for model lipid bilayers, a tripartite relationship among gating modifier toxins, voltage ...

Diversity of Joro Spider Toxins

YAKUGAKU ZASSHI, 1997
In a study to solve a mystery of venom toxicity of the joro spider, Nephila clavata, we purified and identified novel spider toxins such as clavamine, spidamine and joramine. Chemical analyses, bioassays and physical analyses were specifically elaborated in these procedures.

Insecticidal toxins from black widow spider venom

Toxicon, 2007
The biological effects of Latrodectus spider venom are similar in animals from different phyla, but these symptoms are caused by distinct phylum-specific neurotoxins (collectively called latrotoxins) with molecular masses ranging from 110 to 140 kDa. To date, the venom has been found to contain five insecticidal toxins, termed alpha, beta, gamma, delta

Autonomous Hydrogel Actuators Programmed by Endogenous Biochemical Logic for Dual‐Stage Morphing and Drug Release

Advanced Materials, EarlyView.
A 3D‐printed BSA–PEGDA bilayer actuator performs biochemical logic, bending autonomously in acid and releasing its drug payload only when both acid and pepsin are present. This dual‐stage, enzyme‐gated mechanism enables autonomous catch‐and‐release motion and controlled gastric drug delivery, representing a programmable soft material powered by ...
