Neurotoxins can interfere with neurotransmitter function in several ways: - Inhibition of Synthesis: Some neurotoxins inhibit the enzymes necessary for the synthesis of neurotransmitters. - Disruption of Release: Certain neurotoxins can interfere with the release of neurotransmitters from synaptic vesicles. - Receptor Interaction: Neurotoxins can either block or overstimulate receptors, impairing normal neurotransmission. - Enzyme Inhibition: Neurotoxins can inhibit enzymes that degrade neurotransmitters, leading to an accumulation and excessive stimulation.
