Alzheimer's Disease: Overview

Alzheimer's Disease: Overview

Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Alzheimer's Disease: Treatment

Alzheimer's Disease: Treatment

Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Area of Science:

Neuroscience
Molecular Biology
Genetics

Background:

Cryptic RNA splicing is a pathological mechanism implicated in various neurological diseases.
Neuron regeneration is crucial for recovery from neuronal damage but is often limited.
Developing targeted therapies to address RNA splicing defects is a significant challenge.

Purpose of the Study:

To investigate the efficacy of antisense oligonucleotides (ASOs) in correcting cryptic RNA splicing.
To determine if ASO-mediated splicing correction can promote neuron regeneration.
To explore a novel therapeutic strategy for neurological conditions.

Main Methods:

Design and synthesis of specific antisense oligonucleotides targeting cryptic splice sites.
In vitro and in vivo models of neurological conditions with aberrant splicing.
Assessment of RNA splicing patterns using RT-PCR and sequencing.
Evaluation of neuron survival, neurite outgrowth, and functional recovery.

Main Results:

Antisense oligonucleotides successfully corrected cryptic RNA splicing events in affected neurons.
ASO treatment led to significant improvements in neuron survival and regeneration.
Restored RNA splicing correlated with enhanced neuronal function.

Conclusions:

Antisense oligonucleotides are effective in rescuing cryptic RNA splicing.
This splicing correction directly promotes neuron regeneration, highlighting a potential therapeutic avenue.
ASO-based strategies hold promise for treating neurological disorders associated with RNA splicing defects.
