CLEC4D and viral infectious disease: Using Kyoto Encyclopedia of Genes and Genomes (KEGG), we found that besides “asthma,” “influenza A,” and “Th17 cell differentiation-related signals,” the top enriched pathways for these DEGs were also associated with viral infection-related signals including “viral protein interaction with cytokine receptor (CR),” “NOD-like receptor signaling pathway,” and “C-type lectin receptor signaling pathway” (Fig. 1j).
