1. Overview Reason Behind the Study Following World War II, the region of Karelia was split between Finland and the Soviet Union (now Russia). This geopolitical division created an unprecedented natural experiment: two populations sharing nearly identical genetic ancestry and the same geographic latitude, yet diverging dramatically in lifestyle. The Finnish side underwent rapid industrialization, urbanization, and modernization, while the Russian side maintained traditional r

1. Overview Reason Behind the Study The original DIABIMMUNE study established a remarkable finding: despite sharing similar genetic backgrounds, Finnish children had a six-fold higher incidence of type 1 diabetes (T1D) and significantly higher rates of allergies compared to children in Russian Karelia. The study identified that divergent gut microbiome compositions, particularly the dominance of immunologically "silent" Bacteroides species in Finnish infants versus immune-sti

Diabetes — Testing the Hygiene Hypothesis 1. Overview Reason Behind the Study ver eades, devloped nations have witnessed a striking rise in immune-mediated disorders—type 1 diabetes (T1D), allergies, and other autoimmune conditions—while these diseases remain relatively rare in less industrialized regions. The "hygiene hypothesis" emerged as the leading explanatory framework: reduced exposure to pathogens and diverse microbes in modern, sanitized environments may disrupt norm
