A Neuronal and Astrocyte Co-Culture Assay for High Content Analysis of Neurotoxicity
Published on: May 5, 2009
Summary
Acrylamide, a common food contaminant and neurotoxin, may cause cumulative neurotoxicity through various mechanisms. Low-dose exposure can lead to similar effects as high doses, but over longer periods.
Area of Science:
- Toxicology
- Neuroscience
- Environmental Health
Background:
- Acrylamide is a widespread food contaminant and occupational exposure concern.
- It is classified as a neurotoxin with known exposure routes in humans.
- Acrylamide belongs to the 'type-2 alkenes' class of toxic chemicals.
Purpose of the Study:
- To review the neurotoxicity of acrylamide.
- To discuss the potential outcomes of acrylamide exposure.
- To examine hypotheses regarding acrylamide's neurotoxic mechanisms.
Main Methods:
- Literature review of studies on acrylamide neurotoxicity.
- Analysis of proposed mechanisms of acrylamide neurotoxicity.
- Evaluation of dose-response relationships in acrylamide exposure.
Main Results:
- Acrylamide neurotoxicity is hypothesized to involve inhibition of fast axonal transport, neurotransmitter alteration, and direct neurotransmission inhibition.
- Low-dose acrylamide exposure can elicit neurotoxic effects similar to high doses, requiring longer exposure durations.
- Concerns exist regarding the cumulative neurotoxicity of acrylamide, even at low dietary levels.
Conclusions:
- Acrylamide poses a neurotoxic risk through multiple pathways.
- The cumulative effects of chronic low-dose acrylamide exposure warrant further investigation.
- Understanding acrylamide's neurotoxicity is crucial for public health risk assessment.

01:26Physical Properties of Amines
Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.
01:19Amines to Amides: Acylation of Amines
Various carboxylic acid derivatives (such as acid chlorides, esters, and anhydrides) can be used for the acylation of amines to yield amides. The reaction requires two equivalents of amines. The first amine molecule functions as a nucleophile and attacks the carbonyl carbon to produce a tetrahedral intermediate. This is followed by the loss of the leaving group and restoration of the C=O bond.
Next, the second equivalent of amine serves as a Brønsted base and deprotonates the quaternary amide...

01:26Toxic Reactions: Overview
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

01:24Phase II Reactions: Acetylation Reactions
Acetylation, a phase II biotransformation reaction, introduces an acetyl group to drugs or their metabolites. Acetyltransferase enzymes facilitate this reaction, which resembles α-amino acid conjugation due to the addition of a functional group to the drug molecule.
The substrates for acetylation are typically drugs or their metabolites with an amino, sulfonamide, or hydrazine functional group. Acetylation can occur at several points in the drug molecule, including primary, secondary, and...

01:26Anticholinesterase Agents: Poisoning and Treatment
Anticholinesterases, also known as cholinesterase inhibitors, work by blocking the breakdown of acetylcholine, leading to its accumulation in the synaptic cleft. This accumulation indirectly enhances both muscarinic and nicotinic actions. These agents are classified as reversible or irreversible based on their mechanism of action.
Irreversible agents form a strong bond with the cholinesterase enzyme, making it inactive. The breakdown of the phosphorylated enzyme is slower than the...

01:29Hepatic Encephalopathy
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
