The genus Clostridium comprises a number of spore forming Gram positive, rod shaped bacilli. They are found in the intestines of numerous mammalian species including domestic animals, horses, chickens, and humans. They are also widely distributed in the soil and in marine and freshwater sediments.

Release of vasopressin from isolated permeabilized neurosecretory nerve terminals is blocked by the light chain of botulinum A toxin [PDF]
The intracellular action on exocytosis of botulinim A toxin and constituent chains was studied using permeabilized isolated nerve endings from the rat neural lobe. The release of the neuropeptide vasopressin was measured by radioimmunoassay.

On Botulinum Neurotoxin Variability [PDF]
ABSTRACT The rapidly growing number of botulinum neurotoxin sequences poses the problem of the possible evolutionary significance of the variability of these superpotent neurotoxins for toxin-producing Clostridium species. To progress in the understanding of this remarkable phenomenon, we suggest that researchers should (i) abandon an anthropocentric ...

Nanoparticle-mediated delivery of Neurotoxin-II to the brain with intranasal administration: an effective strategy to improve antinociceptive activity of Neurotoxin [PDF]
Background: Neurotoxin-II (NT-II), an analgesic peptide which was separated from the venom of Naja naja atra, is endowed an exceptional specificity of action that block transmission of the nerve impulse by binding to the acetylcholine receptor in the ...

Anatomical Proposal for Botulinum Neurotoxin Injection for Glabellar Frown Lines [PDF]
Botulinum neurotoxin injection for treating glabellar frown lines is a commonly used method; however, side effects, such as ptosis and samurai eyebrow, have been reported due to a lack of comprehensive anatomical knowledge.

A Targeted Therapeutic Rescues Botulinum Toxin-A Poisoned Neurons [PDF]
Botulinum neurotoxin (BoNT), a Category A biothreat agent, is the most potent poison known to mankind. Currently no antidote is available to rescue poisoned synapses.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Capsaicin protects neuromuscular junctions from the inhibitory effects of botulinum neurotoxin A [PDF]
Within 24 hrs after injecting botulinum neurotoxin A (BoNT/A) into the hindlimb, mice lost the toe spread reflex and developed progressive muscle weakness. At the same time, the compound muscle action potential amplitude decreased. Injection of capsaicin

TLC immunostaining characterization of Clostridium botulinum type A neurotoxin binding to gangliosides and free fatty acids [PDF]
The receptor structure of Clostridium botulinum neurotoxin type A was analysed by TLC immunostaining. GQ1b was found to be the most potent receptor, and the neurotoxin also bound to GT1b and GD1a, but not to GM3, GM2, GM1, GD3, GD1b and GT1a.

Diversity and complexity in neural organoids
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
