The results showed that these targets were mainly enriched in human cytomegalovirus infection, Yersinia pestis infection, herpes simplex virus type 1 infection, Kaposi sarcoma-associated herpesvirus infection, the MAPK signaling pathway, shigellosis, the C-type lectin receptor signaling pathway, and HIF-1 signaling pathway. The gene discussed is CLEC4D; the disease is plague.
