Noradrenaline release from permeabilized synaptosomes is inhibited by the light chain of tetanus toxin [PDF]
Noradrenaline release from rat brain cortical synaptosomes permeabilized with streptolysin O can be triggered by μM concentrations of free Ca2+. This process was inhibited within minutes by tetanus toxin and its isolated light chain, but not by its heavy

Summary1. Death in several infectious diseases is caused by protein toxins secreted by invading bacteria. Cholera toxin is a simple protein secreted by Vibrio cholerae colonizing the gut; it is responsible for the massive diarrhoea that is cholera.2. The primary action of cholera toxin is an activation of adenylate cyclase, an enzyme found on the inner

Patient-Reported Side Effects of Intradetrusor Botulinum Toxin Type A for Idiopathic Overactive Bladder Syndrome [PDF]
Objective: The aim of the study was a prospective assessment of patient-reported side effects in an open-label study after intradetrusor botulinum toxin injections for idiopathic overactive bladder (OAB). Patients and Methods: Botulinum toxin A injection

The actions of Pasteurella multocida toxin on neuronal cells [PDF]
Pasteurella multocida toxin (PMT) activates the G-proteins Gα, Gα, Gα Gα and Gα by deamidation of specific glutamine residues. A number of these alpha subunits have signalling roles in neurones.

Comparative genomics of Shiga toxin encoding bacteriophages [PDF]
Background Stx bacteriophages are responsible for driving the dissemination of Stx toxin genes (stx) across their bacterial host range. Lysogens carrying Stx phages can cause severe, lifethreatening disease and Stx toxin is an integral virulence factor.

Biomedical Community and the Biological and Toxin Weapons Convention [PDF]
YesNegotiations to find a legally binding way to strengthen the Biological and Toxin Weapons Convention (BTWC) of 1972 [1]are in danger of failing. The crisis was precipitated during the current round of talks, now in its final week in Geneva, when the

The Toxins of Cyanobacteria [PDF]
Cyanobacteria , formerly called ”blue-green algae“, are simple, primitive photosynthetic microorganism wide occurrence in fresh, brackish and salt waters. Forty different genera of Cyanobacteria are known and many of them are producers of potent toxins responsible for a ...

The coevolution of toxin and antitoxin genes drives the dynamics of bacterial addiction complexes and intragenomic conflict [PDF]
Bacterial genomes commonly contain 'addiction' gene complexes that code for both a toxin and a corresponding antitoxin. As long as both genes are expressed, cells carrying the complex can remain healthy.

Chaperone-mediated native folding of a β-scorpion toxin in the periplasm of E.coli [PDF]
Background: Animal neurotoxin peptides are valuable probes for investigating ion channel structure/function relationships and represent lead compounds for novel therapeutics and insecticides.

How ricin and shiga toxin reach the cytosol of target cells : retrotranslocation from the endoplasmic reticulum [PDF]
A number of protein toxins bind at the surface of mammalian cells and after endocytosis traffic to the endoplasmic reticulum, where the toxic A chains are liberated from the holotoxin.
