The neonatal window of opportunity-early priming for life

The concept of the neonatal window of opportunity assigns the early postnatal period a critical role for lifelong host-microbial and immune homeostasis. It is supported by epidemiological evidence that links postnatal environmental exposure with disease susceptibility and mechanisms in the neonate host that facilitate the postnatal transposition, establish a stable microbiome, and promote immune maturation. During the conference on “The neonatal window of opportunity – early priming for life,” postnatal micro-biome and immune maturation, epidemiological evidence, and fundamental mechanisms were discussed to identify new targets for future preventive and interventional measures.

From December 5 to 7, 2016, the Herrenhausen Conference “The neonatal window of opportunity – early priming for life” took place at Hannover, Germany, sponsored by the Volkswagen Foundation. The concept of the “neonatal window of opportunity,” that is, a critical nonredundant time frame in a newborn’s life during which environmental factors drive immune and tissue maturation and influence the susceptibility to immune-mediated and other diseases in adult life, was discussed.
