TLR7 and infection: Disease classes represented by this gene set (haematological, immune and infection) support this conclusion, and suggest that zinc can regulate not only hepatic immunity (IRF9, TLR7, STAT1), but immune cell migration (CXCL10, CCL19, CCL21), adhesion (COL1A1, COL3A1, COL4A1, ITGA2, ITGB5) and activation (HLA-A, HLA-B, HLA-H).
