Common examples of neurotoxins include lead, [7] ethanol (drinking alcohol), [8] glutamate, [9] nitric oxide, [10] botulinum toxin (e.g. Botox), [11] tetanus toxin, [12] and tetrodotoxin. [6] Some substances such as nitric oxide and glutamate are in fact essential for proper function of the body and only exert neurotoxic effects at excessive ...
An example is through the nicotinic acetylcholine receptor (nAchRs), which is a receptor commonly found along the surfaces of the cells that respond to nicotine stimulation, turning them on or off. Aβ was found manipulating the level of nicotine in the brain along with the MAP kinase , another signaling receptor, to cause cell death.
Tetanus toxin (TeNT) is an extremely potent neurotoxin produced by the vegetative cell of Clostridium tetani [1] in anaerobic conditions, causing tetanus. It has no known function for clostridia in the soil environment where they are normally encountered. It is also called spasmogenic toxin, tentoxilysin, tetanospasmin, or tetanus neurotoxin.
Anatoxin-a is a neurotoxin produced by multiple genera of freshwater cyanobacteria that are found in water bodies globally. [3] Some freshwater cyanobacteria are known to be salt tolerant and thus it is possible for anatoxin-a to be found in estuarine or other saline environments. [4]
Clostridium botulinum is a gram-positive, [1] rod-shaped, anaerobic, spore-forming, motile bacterium with the ability to produce botulinum toxin, which is a neurotoxin. [2] [3]C. botulinum is a diverse group of pathogenic bacteria.
Domoic acid is a neurotoxin released by Pseudo-nitzschia, a common phytoplankton species found in coastal waters. Sea lions — and other marine mammals — become poisoned when they eat large ...

Some exotoxins act directly at the ribosome to inhibit protein synthesis. An example is Shiga toxin. Other toxins act at elongation factor-2. In the case of the diphtheria toxin, EF2 is ADP-ribosylated and becomes unable to participate in protein elongation, and, so, the cell dies. Pseudomonas exotoxin has a similar action.
