neuronal-peptides Neurotoxic peptides are a class of molecules that can adversely affect the nervous systemWhy is the amyloid beta peptide of Alzheimer's disease .... These peptides, often found in natural toxins like venoms, can disrupt neuronal function through various mechanisms. Research into neurotoxic peptides spans from understanding their origins in organisms like stinging trees and scorpions to developing computational models for predicting their activity and exploring their potential therapeutic applicationsClearance of neurotoxic peptides and proteins by .... The study of these compounds is crucial for both understanding neurological disorders and for developing countermeasures or novel treatments.
Neurotoxic peptides originate from a diverse array of biological sources. Prominent among these are animal venoms, such as those from snakes, scorpions, and jellyfish (cnidarians). For instance, the venom of the giant Australian stinging tree (Dendrocnide species) contains previously unknown pain-inducing peptides that activate sensory neurons.A large language model for predicting neurotoxic peptides ... Similarly, cnidarian peptide neurotoxins are known to specifically target voltage-gated ion channels, thereby inhibiting nervous system function.
Beyond animal venoms, certain endogenous peptides can also exhibit neurotoxic properties. Amyloid beta (Aβ) oligomers, implicated in Alzheimer's disease, are recognized as neurotoxic, causing damage to neurons and axons through various mechanisms, including interaction with cell membranesNeurotoxic and cytotoxic peptides underlie the painful .... The study of these peptides contributes to understanding neurodegenerative processes and potential pathways for interventionA large language model for predicting neurotoxic peptides ....
The accurate identification and prediction of neurotoxic peptides are vital for safety evaluations, particularly concerning therapeutic proteins and genetically modified organisms. Recent advancements in computational biology have led to the development of sophisticated models, including those utilizing large language models, to predict neurotoxicity in peptides and proteins. These models analyze amino acid profiles and other molecular characteristics to distinguish between neurotoxic and non-neurotoxic sequences.作者：MH Ling—'Study ofneurotoxic peptidesfrom Chinese scorpion Buthus martensi Karsch' published in 'Peptide Science — Present and Future' For example, research has shown that neurotoxic peptides may exhibit a higher abundance of certain amino acids like cysteine, glycine, and lysine.作者：EK Gilding·2020·被引用次数：33—We show here that the venoms of Australian Dendrocnide species contain heretoforeunknown pain-inducing peptidesthat potently activate mouse sensory neurons.
While inherently toxic, the study of neurotoxic peptides also opens avenues for therapeutic development. Their specific interactions with neuronal targets, such as voltage-gated calcium and sodium channels, can be leveraged. For example, some neuroprotective peptides derived from snake venoms, despite their primary role in predation, exhibit selective neurotoxicity that could be harnessed for medicinal purposesClearance of neurotoxic peptides and proteins by .... Furthermore, understanding how neurotoxic peptides are cleared from the system, such as across the blood-brain barrier, is crucial for developing treatments for conditions like Alzheimer's disease.A large language model for predicting neurotoxic peptides ... Research into the properties of neurotoxic peptides, such as those related to the BRI gene, can also shed light on the mechanisms underlying various dementias and neurological disorders.Neurotoxic peptides from the venom of the giant Australian ...
Neurotoxic peptides represent a complex area of study, bridging the fields of toxicology, neuroscience, and molecular biology.A large language model for predicting neurotoxic peptides ... From their potent effects in natural toxins to their potential implications in diseases like Alzheimer's and their role in ongoing scientific prediction models, these molecules continue to be a focus of intensive research. Understanding their sources, mechanisms of action, and biological interactions is essential for advancing our knowledge of the nervous system and for developing innovative strategies in medicine and toxicology.
