Cleaved intracellular SNARE peptides are implicated in a novel cytotoxicity mechanism of botulinum serotype C [PDF]

open access: yes, 2013
Recent advances in intracellular protein delivery have enabled more in-depth analyses of cellular functions. A specialized family of SNARE proteases, known as Botulinum Neurotoxins, blocks neurotransmitter exocytosis, which leads to systemic toxicity ...

Long‐Term Safety and Efficacy of Repeat Treatments with DaxibotulinumtoxinA in Cervical Dystonia: Results from the ASPEN‐Open‐Label Study

open access: yesMovement Disorders Clinical Practice, EarlyView.
ABSTRACT Background DaxibotulinumtoxinA (DAXI), a novel botulinum neurotoxin (BoNT) formulation, was shown to be safe, effective, and long‐lasting in the treatment of cervical dystonia (CD) over one treatment cycle in the phase 3, randomized, placebo‐controlled ASPEN‐1 trial.

Structural Insights into Rational Design of Single-Domain Antibody-Based Antitoxins against Botulinum Neurotoxins. [PDF]

open access: yes, 2020
Botulinum neurotoxin (BoNT) is one of the most acutely lethal toxins known to humans, and effective treatment for BoNT intoxication is urgently needed. Single-domain antibodies (VHH) have been examined as a countermeasure for BoNT because of their high ...

Amylase release from streptolysin O-permeabilized pancreatic acinar cells. Effects of Ca2+, guanosine 5'-[gamma-thio]triphosphate, cyclic AMP, tetanus toxin and botulinum A toxin [PDF]

open access: yes, 1992
The molecular requirements for amylase release and the intracellular effects of botulinum A toxin and tetanus toxin on amylase release were investigated using rat pancreatic acinar cells permeabilized with streptolysin O.

Structure of dual receptor binding to botulinum neurotoxin B [PDF]

open access: yes, 2014
Botulinum neurotoxins are highly toxic, and bind two receptors to achieve their high affinity and specificity for neurons. Here we present the first structure of a botulinum neurotoxin bound to both its receptors.

Functional Head Tremor: Contrasting Features with Other Tremor Etiologies

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Functional tremor (FT) is considered the most common phenomenology among patients with functional movement disorders (FMDs). Most patients have limb tremor, but they can also present with tremor involving the head and trunk. Objectives and Methods We aimed to assess the clinical phenomenology of functional head tremor (FHT) and ...

Outbreak of botulism in horses associated with toxin A and D in São Paulo state, Brazil

open access: yesPesquisa Veterinária Brasileira
: Botulism is a neuromuscular disorder caused by neurotoxins produced by Clostridium botulinum. Equine botulism has been frequently reported worldwide; however, descriptions of cases in South America remain uncommon.

Widespread Sequence Variations in VAMP1 across Vertebrates Suggest a Potential Selective Pressure from Botulinum Neurotoxins [PDF]

open access: yes, 2014
Botulinum neurotoxins (BoNT/A-G), the most potent toxins known, act by cleaving three SNARE proteins required for synaptic vesicle exocytosis. Previous studies on BoNTs have generally utilized the major SNARE homologues expressed in brain (VAMP2 ...
