Several genera of cyanobacteria are able to produce toxins that may be accessible for use as chemical warfare agents. Important toxins include those that primarily affect the liver, such as microcystins, nodularins, and cylindrospermopsin. Important toxins that primarily affect the nervous system ...
Ergot alkaloids are known to affect the nervous system and to be vasoconstrictors. Historically, ingestion of contaminated grain, particularly rye, has been implicated in epidemics of both gangrenous and convulsive ergotism (St. Anthony's fire), although such epidemics no longer occur in humans du...
Bacterial products can act on neurons to alter signaling and function. In the present study, we found that dorsal root ganglion (DRG) sensory neurons are enriched for ANTXR2, the high-affinity receptor for anthrax toxins. Anthrax toxins are composed of p
The venom of the spider Phoneutria nigriventer contains a mixture of toxins that affect ion channel function, decreasing neuronal cell death and ameliorating neurotransmission alterations. The PhTx3-1 toxin is capable of blocking transient outward K+ currents (KvIA), improving ...
The peptide is derived from the intracellular processing of the antigenic protein. Peptide sequences from protein antigens that can stimulate the activity of T-cells via presentation on MHC class II molecules are generally referred to as “T-cell epitopes”. Such T-cell epitopes are any amino ...

Toxicity of both toxins in periphery may be attributed to the direct effect on muscle. Our data elucidate, for the first time, how differenttoxins affect mammalian central and peripheral excitable cells, and reveal unexpected subtype specificity of toxins that interact with receptor site 3. 展开 ...
Fungal toxins include the aflatoxins that can contaminate cereals; they are associated with chronic liver disease and liver cancer. All venoms are diverse mixtures of different toxins, so the effects in humans can be complex and variable [1]. Scorpion venoms contain many toxins that affect ion ...
