Botulinum Toxin Type A Exerts Direct Trans-Synaptic Action at Bilateral Spinal Nociceptive Circuits.
Botulinum toxin type A (BoNT-A) induces a bilateral analgesic effect following unilateral injection in rodent bilateral or mirror pain models. This occurs either by indirect plasticity-related actions, or by the toxin's direct central actio…

Beyond neuromuscular activity: botulinum toxin type A exerts direct central action on spinal control of movement.
Overt muscle activity and impaired spinal locomotor control hampering coordinated movement is a hallmark of spasticity and movement disorders like dystonia. While botulinum toxin A (BoNT-A) standard therapy alleviates mentioned symptoms pre…

Botulinum toxin type a antinociceptive activity in trigeminal regions involves central transcytosis.
[OBJECTIVE] Botulinum toxin type A (BoNT-A) provides lasting pain relief in patients with craniofacial pain conditions but the mechanisms of its antinociceptive activity remain unclear. Preclinical research revealed toxin axonal transport t…

Native botulinum toxin type A vs. redesigned botulinum toxins in pain: What did we learn so far?
Driven by the clinical success of botulinum toxin serotype A (BoNT/A) and the need for improved chronic pain management, researchers attempted to develop re-designed botulinum toxin (BoNT)-based molecules as novel analgesics. Various recomb…

Antinociceptive Actions of Botulinum Toxin A1 on Immunogenic Hypersensitivity in Temporomandibular Joint of Rats.
Botulinum neurotoxin type A1 (BoNT-A) reduces the peripheral peptide and cytokine upregulation in rats with antigen-evoked persistent immunogenic hypersensitivity (PIH) of the temporomandibular joint (TMJ). Herein, we examined the effects o…

Detection of VAMP Proteolysis by Tetanus and Botulinum Neurotoxin Type B In Vivo with a Cleavage-Specific Antibody.
Tetanus and Botulinum type B neurotoxins are bacterial metalloproteases that specifically cleave the vesicle-associated membrane protein VAMP at an identical peptide bond, resulting in inhibition of neuroexocytosis. The minute amounts of th…

Lasting Peripheral and Central Effects of Botulinum Toxin Type A on Experimental Muscle Hypertonia in Rats.
Recent animal experiments suggested that centrally transported botulinum toxin type A (BoNT-A) might reduce an abnormal muscle tone, though with an unknown contribution to the dominant peripheral muscular effect observed clinically. Herein,…
-
Evidence for central antispastic effect of botulinum toxin type A.
[BACKGROUND AND PURPOSE] Botulinum toxin type A (BoNT/A) injections into hyperactive muscles provide effective treatment for spasticity and dystonias, presumably due to its local effects on extrafusal and intrafusal motor fibres. A recent d…

Mechanisms of Botulinum Toxin Type A Action on Pain.
Already a well-established treatment for different autonomic and movement disorders, the use of botulinum toxin type A (BoNT/A) in pain conditions is now continuously expanding. Currently, the only approved use of BoNT/A in relation to pain…

Involvement of substance P in the antinociceptive effect of botulinum toxin type A: Evidence from knockout mice.
The antinociceptive action of botulinum toxin type A (BoNT/A) has been demonstrated in behavioral animal studies and clinical settings. It was shown that this effect is associated with toxin activity in CNS, however, the mechanism is not fu…

Activity of botulinum toxin type A in cranial dura: implications for treatment of migraine and other headaches.
[BACKGROUND AND PURPOSE] Although botulinum toxin type A (BoNT/A) is approved for chronic migraine treatment, its mechanism of action is still unknown. Dural neurogenic inflammation (DNI) commonly used to investigate migraine pathophysiolog…

Effects of botulinum toxin type A facial injection on monoamines and their metabolites in sensory, limbic and motor brain regions in rats.
Despite its toxicity, botulinum neurotoxin type A (BTX-A) is a valuable therapeutic agent for several motor, autonomic and pain disorders. Numerous studies have described its peripheral as well as central effects. Using reversed-phase High …

Botulinum toxin type A in motor nervous system: unexplained observations and new challenges.
In the motor system, botulinum toxin type A (BoNT/A) actions were classically attributed to its well-known peripheral anticholinergic actions in neuromuscular junctions. However, the enzymatic activity of BoNT/A, assessed by the detection o…
