Funnelweb–Spider Venom Antagonist

Medical Journal of Australia, 1980
It was found in a series of experiments on anaesthetized monkeys that rat plasma and rat euglobulin fractions contain a substance which could offer some protection against funnelweb-spider envenomation when administered before envenomation or simultaneously with the funnelweb-spider venom. Further work to isolate, identify, and purify this substance is

Chromosomal‐level genome of a sheet‐web spider provides insight into the composition and evolution of venom

Molecular Ecology Resources, 2022
Spiders are the most abundant venomous predators in the world. Previous research related to spider venom has mostly relied on transcriptomes and proteomes, with only a few high‐quality genomes available.

Spider Venoms and Spider Toxins

Journal of Toxicology: Toxin Reviews, 1998
AbstractSpider venoms and toxins are useful tools for the study of ion channels and synaptic functions of neurons in vertebrates and invertebrates. The components of spider venom, such as proteins, peptides, polyamines and bioamines, are species-specific. The various functions of these toxins are reviewed in this paper.

A spider-venom peptide with multi-target activity on sodium and calcium channels alleviates chronic visceral pain in a model of irritable bowel syndrome.

Pain, 2020
Chronic pain is a serious debilitating condition that affects ∼20% of the world's population. Currently available drugs fail to produce effective pain relief in many patients and have dose-limiting side effects.

Latarcins: versatile spider venom peptides

Cellular and Molecular Life Sciences, 2015
Arthropod venoms feature the presence of cytolytic peptides believed to act synergetically with neurotoxins to paralyze prey or deter aggressors. Many of them are linear, i.e., lack disulfide bonds. When isolated from the venom, or obtained by other means, these peptides exhibit common properties.

Molecular diversity of spider venom

Biochemistry (Moscow), 2009
Spider venom, a factor that has played a decisive role in the evolution of one of the most successful groups of living organisms, is reviewed. Unique molecular diversity of venom components including substances of variable structure (from simple low molecular weight compounds to large multidomain proteins) with different functions is considered ...
