Insights

Alzheimer's disease treatments targeting amyloid beta have failed. This review explores the role of zinc in neurotransmission and its interaction with amyloid beta oligomers (AβO) as a novel therapeutic target.

Area of Science:

  • Neuroscience
  • Biochemistry
  • Pharmacology

Background:

  • Alzheimer's disease (AD) therapeutics targeting amyloid beta have shown limited success.
  • Novel therapeutic targets are needed to halt or slow AD progression.
  • Soluble amyloid beta in oligomeric forms (AβO) interact with zinc.

Purpose of the Study:

  • To review the interaction between AβO and zinc.
  • To explore the role of zinc in neurotransmission and its neurotoxic effects.
  • To discuss potential AD treatments modulating zinc homeostasis and hyperexcitability.

Main Methods:

  • Literature review of existing studies on AβO, zinc, and neurotransmission.
  • Analysis of experimental data from animal models of AD.
  • Exploration of therapeutic strategies targeting zinc modulation.

Main Results:

  • AβO bind with high affinity to zinc released during synaptic activity.
  • Zinc plays a role in neurotransmission and may contribute to neurotoxicity in AD.
  • Animal models suggest modulation of hyperexcitability and zinc homeostasis as potential treatments.

Conclusions:

  • Targeting the AβO-zinc interaction represents a promising therapeutic strategy for AD.
  • Modulating zinc homeostasis and neuronal hyperexcitability may offer new avenues for AD treatment.
  • Further research into zinc's role in AD pathogenesis is warranted.

Ligand-Gated Ion Channel Receptor: Gating Mechanism

Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

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...

Gut-Brain Axis

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

Indirect-Acting Cholinergic Agonists: Pharmacological Actions

Indirect-acting cholinergic agonists, also known as anticholinesterases, exert their pharmacological effects by enhancing cholinergic transmission in various body parts, including the neuromuscular junction, autonomic cholinergic synapses, and the brain.
At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...
