Botulinum toxin for injection is a purified and diluted protein which isolated from the bacterium Clostridium botulinum . It one of most potent toxins known to humankind. C. an anaerobic Gram-positive, spore-forming present naturally in soil, plants, static water bodies, gastrointestinal tract mammals aquatic life. Different formulations are available. FDA approval these varies. This article re...

Gangliosides, glycosphingolipids present in the membranes of neuronal and other cells, are natural receptors for a number of bacterial toxins and viruses whose sensitive detection is of interest in clinical medicine as well as in biological warfare or terrorism incidents. Liposomes containing gangliosides mimic cells that are invaded by bacterial toxins and can be used as sensitive probes for d...

and immunohistochemical evidence for central antinociceptive activity of botulinum toxin A.

Botulism is a neuroparalytic disease caused by neurotoxin produced from the bacterium Clostridium botulinum. The botulinum neurotoxins (BoNTs) are among the most potent known biological toxins and have an estimated human median lethal dose (LD50) in the nanogram/kilogram range. Botulinum toxins have historically been employed as biological weapons (BW) through state-sponsored programs in Japan,...

There are seven different serotypes of botulinum toxin available for study. Each serotype binds to receptor proteins at cholinergic terminals, although there may be different receptor proteins for different serotypes, and each produces a blockade of cholinergic neurotransmission in striated muscle (Martin, 1997; Schiavo et al., 1992; Blasi et al., 1993). The toxins also affect gamma motor neuro...

Lack of Interchangeability Between Botulinum Toxin Products The potency Units of BOTOX® are specific to the preparation and assay method utilized. They are not interchangeable with other preparations of botulinum toxin products and, therefore, Units of biological activity of BOTOX® cannot be compared to nor converted into Units of any other botulinum toxin products assessed with any other speci...

Botulinum toxins are metalloproteases that act inside nerve terminals and block neurotransmitter release through their cleavage of components of the exocytosis machinery. These toxins are used to treat human diseases that are characterized by hyperfunction of cholinergic terminals. Recently, evidence has accumulated that gangliosides and synaptic vesicle proteins cooperate to mediate toxin bind...
