Product Description
Aflatrem is the secondary metabolite of Aspergillus flavus. It is able to induce degeneration of neuronal processes in hippocampal neurotransmitter systems at low dose. It potentiates the gamma-aminobutyric acid (GABA)-induced chloride current. It is a tremorgenic mycotoxin with acute neurotoxic effect.

Mechanism Of Toxicity | Tremorgenic mycotoxins exert their toxic effects by interfering with neurotransmitter release, possibly by causing degeneration of nerve terminals. They are thought to inhibit gamma-aminobutyric acid (GABA) receptors, both pre- and postsynaptic, as well as inhibit transmitter breakdown at the GABA-T receptors. This would initially increase neurotransmitter levels, potentiating the GABA-induced chloride current, then lead to decreased levels of neurotransmitter in the synapse. In addition, aflatrem inhibits presynaptic high-conductance Ca+2 activated maxi-K+ channels in the smooth muscle. |
