Nervous System Disease Model Construction Service for Exosome Functional Research

Exosome research is an emerging and rapidly developing field that has received increasing attention. In existing studies, exosomes have played a significant role in targeting, immunogenicity, and carrying biologically active molecules, making them play an important role in the treatment of nervous system diseases (NSDs). These suggest that researchers can start from the direction of exosomes to find new therapeutic avenues. During the development of therapeutic exosomes, the selection of appropriate animal models is helpful for the development of effective therapeutic drugs. Creative Biolabs can provide a variety of stable and high-quality NSD animal models to help customers achieve their goals.

Creative Biolabs Nervous System Disease Model Library for Exosome Functional Research

We can provide including but not limited to the following NSD animal models for exosome functional research.

NSD Animal Models	Inducer	Induction Mechanism	Applicable Animals	Model Features
Parkinson's disease (PD) animal models	6-hydroxydopamine (6-OHDA) induction	6-OHDA has strong neurotoxicity, can cause acute degeneration of sympathetic adrenergic nerve endings, and eventually cause irreversible damage to neurons.	Rat	This model is suitable for the study of the pathogenesis, treatment, and long-term observation of PD, especially for the study of pathophysiological changes in the middle and late stages of human PD.
	Rotenone induction	Rotenone is lipophilic, can pass through the blood-brain barrier, and has a strong and extensive inhibitory effect on the activity of mitochondrial respiratory chain complex I in brain tissue.	Rat	The model can better simulate PD-related characteristics in terms of pathology, biochemistry, pathogenic mechanism, and behavior.
	1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induction	MPTP is a natural insecticide, which is highly lipophilic and easily penetrates the blood-brain barrier. After entering the brain, MPTP can inhibit the activity of mitochondrial respiratory chain complex I, leading to the degeneration and death of dopaminergic neurons.	Mouse	The production cycle of this model is short, its neuron loss is obvious and the behavioral test is abnormal. It is currently one of the most commonly used PD animal models.
Alzheimer's disease (AD) animal models	APP/PS1 mice	APP/PS1 double transgenic mice express a fusion consisting of mutated presenilin (DeltaE9) and amyloid precursor protein (APPswe). β-amyloid deposits are produced in the brain of mice aged 6-7 months.	Mouse	This model is the most classic model for studying AD.
Alzheimer's disease (AD) animal models	3XTG mice	3XTG mice carry three AD-related genes, namely Psen1, APPswe, and tauP301L. At 12-15 months of age, this mouse had excess tau phosphorylated multimers in the hippocampus.	Mouse	This mouse exhibited plate and tangle pathology associated with synaptic dysfunction, which is similar to clinical AD pathology.
Epilepsy animal models	Combined induction of lithium chloride and pilocarpine	Pilocarpine activates acetylcholine receptors in the brain, causing persistent generalized tonic-clonic seizures. Lithium chloride can effectively increase the sensitivity of the body to pilocarpine, reduce the dosage of pilocarpine, and significantly reduce animal mortality caused by the toxic effect of pilocarpine.	Rat	The development process of this model is highly similar to that of human temporal lobe epilepsy, and it is an ideal model for studying temporal lobe epilepsy.
