OBJECTIVES: Guillain-Barre syndrome (GBS) results from autoimmune attack on the peripheral nerves, causing sensory, motor and autonomic abnormalities. Emerging evidence suggests that there might be an association between COVID-19 and GBS. Nevertheless, the underlying pathophysiological mechanism remains unclear. MATERIALS AND METHODS: We performed bioinformatic analyses to delineate the potential genetic crosstalk between COVID-19 and GBS. RESULTS: COVID-19 and GBS were associated with a similar subset of immune/inflammation regulatory genes, including TNF, CSF2, IL2RA, IL1B, IL4, IL6 and IL10. Protein-protein interaction network analysis revealed that the combined gene set showed an increased connectivity as compared to COVID-19 or GBS alone, particularly the potentiated interactions with CD86, IL23A, IL27, ISG20, PTGS2, HLA-DRB1, HLA-DQB1 and ITGAM, and these genes are related to Th17 cell differentiation. Transcriptome analysis of peripheral blood mononuclear cells from patients with COVID-19 and GBS further demonstrated the activation of interleukin-17 signalling in both conditions. CONCLUSIONS: Augmented Th17 cell differentiation and cytokine response was identified in both COVID-19 and GBS. PBMC transcriptome analysis also suggested the pivotal involvement of Th17 signalling pathway. In conclusion, our data suggested aberrant Th17 cell differentiation as a possible mechanism by which COVID-19 can increase the risk of GBS.
