Highlights in the knowledge of brown spider toxins

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2017
Brown spiders are venomous arthropods that use their venom for predation and defense. In humans, bites of these animals provoke injuries including dermonecrosis with gravitational spread of lesions, hematological abnormalities and impaired renal function.

An Economic Dilemma between Molecular Weapon Systems May Explain an Arachno-Atypical Venom in Wasp Spiders (Argiope bruennichi)

open access: yesBiomolecules, 2020
Spiders use venom to subdue their prey, but little is known about the diversity of venoms in different spider families. Given the limited data available for orb-weaver spiders (Araneidae), we selected the wasp spider Argiope bruennichi for detailed ...

Fugitive Junctures: Life‐Seeking, Route‐Finding and the Mobile Ensemble at Kenya's Borders

open access: yesTransactions of the Institute of British Geographers, EarlyView.
Short Abstract Fugitivity has become an important conceptual frame to understand the illegalised mobilities of contemporary migrants in conjunction with enslaved people's historical lines of flight as spatial praxes to seize their own freedom. Thinking from Kenya, and drawing on research with migrants, border officials, activists, police and smugglers,

Pharmacology of spider venom toxins

open access: yesToxin Reviews, 2014
AbstractSpider venom is an intricate combination of target specific enzymatic and non-enzymatic toxins. In addition, the venom also contains polyamine neurotoxins, ATP, AMP, ADP, guanosine, 2,4,6-trihydroxy purine, γ-aminobutyric acid, glutamic acid, aspartic acid, taurine, histamine, serotonin, tyramine, octomine, nor-adrenaline and inorganic salts ...

Acute tetraparesis in a labrador retriever with suspected ectopic insulinoma and paraneoplastic polyneuropathy

open access: yesVeterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Summary This case report describes a 10‐year‐old, male, neutered labrador retriever that was presented with acute non‐ambulatory tetraparesis, later diagnosed with an ectopic insulinoma and paraneoplastic polyneuropathy. Clinical evaluation revealed severe hypoglycaemia, generalised neuromuscular signs and electromyography findings were consistent with

Axon Initial Segment: Structure, Biological Functions, Diseases, and Therapeutic Targets

open access: yesMedComm, Volume 7, Issue 4, April 2026.
The axon initial segment (AIS) is a specialized axonal domain critical for maintaining neuronal polarity, action potential initiation, and network stability. This review summarizes the necessary elements for maintaining AIS structure and plasticity, discussing crucial biological functions of AIS in neuronal signaling and the neural circuit homeostasis,

Spider Neurotoxins, Short Linear Cationic Peptides and Venom Protein Classification Improved by an Automated Competition between Exhaustive Profile HMM Classifiers

open access: yesToxins, 2017
Spider venoms are rich cocktails of bioactive peptides, proteins, and enzymes that are being intensively investigated over the years. In order to provide a better comprehension of that richness, we propose a three-level family classification system for ...

A century of theories of balancing selection

open access: yesBiological Reviews, Volume 101, Issue 2, Page 804-825, April 2026.
ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

The Dual Prey-Inactivation Strategy of Spiders—In-Depth Venomic Analysis of Cupiennius salei

open access: yesToxins, 2019
Most knowledge of spider venom concerns neurotoxins acting on ion channels, whereas proteins and their significance for the envenomation process are neglected.
