COVID-19 related epigenetic changes and atopic dermatitis: An exploratory analysis

Area of Science:

• Immunology
• Genetics
• Epidemiology

Background:

• Epidemiological studies suggest a link between atopic dermatitis (AD) and COVID-19.
• The molecular mechanisms connecting COVID-19 and AD remain largely unknown.

Purpose of the Study:

• To determine if COVID-19-associated CpG sites contribute to AD development.
• To investigate if gene expression regulation mediates the association between COVID-19 and AD.

Main Methods:

• Utilized Mendelian randomization and transcriptome analysis.
• Identified significant CpG sites associated with COVID-19 and AD risk.

Main Results:

• Three CpG sites (cg04543273, cg11916609, cg10636246) showed significant impact on AD risk.
• CpG site cg04543273 inhibited LMAN2 expression; others had no significant effect.
• LMAN2 expression was upregulated in COVID-19 patients and correlated with Type 2 helper cells.

Conclusions:

• This research offers insights into COVID-19-related epigenetic changes impacting AD.
• A potential role for LMAN2 in the interplay between viral infections and AD is proposed.
• Further research is needed to elucidate LMAN2's immunopathology in this context.
