We anticipate that these results will provide potential therapeutic agents and advances in precision medicine. is probably protective against helminth infection. This finding suggests that an increased incidence of IgAN in some geographic areas may represent an untoward consequence of protective adaptation to mucosal invasion by local pathogens. In addition, the notion of shared genetic components in immune-related diseases, such as inflammatory bowel disease (IBD) and IgAN, has been studied widely.11, 12, 13, 14, 15, 16, 17 Using increasing amounts of data on the role of infection in autoimmune diseases,18, 19 Couser and Johnson20 summarized the triggering role of infection in the pathogenesis of various glomerulonephritic conditions, including IgAN.
