Celiac disease, inflammation and oxidative damage: a nutrigenetic approach

Area of Science:

• Immunology
• Gastroenterology
• Nutritional Science

Background:

• Celiac disease (CD) is a chronic inflammatory condition of the small intestine triggered by gluten/gliadin intolerance.
• Genetic and environmental factors contribute to CD pathogenesis.
• Proteomics has advanced understanding of prolamin toxicity and CD's biochemical/immunological aspects.

Purpose of the Study:

• To explore the role of nutrigenomics and nutrigenetics in understanding diet-gene interactions in CD.
• To investigate the potential protective effects of dietary components against gliadin peptide toxicity.
• To evaluate the role of specific nutrients in the nutritional therapy of celiac disease.

Main Methods:

• Review of scientific literature on celiac disease, proteomics, nutrigenomics, and nutrigenetics.
• Analysis of studies investigating gliadin peptide effects on intestinal cells.
• Examination of research on dietary components modulating oxidative stress and gene expression.

Main Results:

• Certain gliadin peptides can directly impact intestinal cells by altering gene expression and oxidative stress.
• Nutrigenomics and nutrigenetics illuminate diet-gene interactions relevant to CD.
• Dietary components like ω-3 fatty acids, flavonoids, and carotenoids can modulate inflammatory pathways.

Conclusions:

• Dietary components may preserve intestinal barrier integrity in celiac disease.
• Specific nutrients show potential in protecting against gliadin peptide toxicity.
• Nutritional interventions hold promise for celiac disease management.
